 PORTABLE COMMUNICATION TERMINAL, RADIO COMMUNICATION DEVICE, PORTABLE COMMUNICATION SYSTEM, AND COMMUNICATION CONTROL METHOD

 Technical field

 The present invention relates to a technology for communication control or power control in the case where wireless communication is performed between a predetermined mobile communication terminal and a wireless communication apparatus which is a partner communication terminal, for example, a relatively short distance wireless communication. In order to control a portable communication terminal such as a portable telephone terminal provided with a communication means for performing communication and a communication means for performing relatively long distance wireless communication, and a wireless communication apparatus which is a partner communication terminal It is used.

 Background art

 [0002] Modern cellular phones and personal digital assistants (PDAs) have various functions! . For example, many mobile phone terminals have a function for performing short-range wireless communication, in addition to the function of performing wireless communication with the base station of the mobile phone, which is the original communication function.

 [0003] As short-range wireless communication, for example, wireless communication conforming to Bluetooth (registered trademark), IEEE802.11 standards, etc. (for example, wireless LAN), UWB (Ultra Wide Band, ultra-wide band wireless), Wireless USB Wireless communication such as (Wireless Universal Serial Bus, Wireless USB), ZigBee (ZigBee), wireless communication in 426 MHz band, wireless communication in 304 MHz band, etc. are assumed.

 [0004] By the way, since the portable telephone terminal and the portable information terminal are portable, the power supplied from the built-in battery power is used as a power supply for operating the electric circuit. Therefore, it is important to reduce power consumption in order to realize long-term circuit operation using limited battery power. In addition, in places such as hospitals and aircraft, it is obligated to turn off the mobile phone's power supply.

Therefore, for example, Patent Document 1 discloses a conventional technique relating to automatically powering off the mobile phone terminal. That is, in Patent Document 1, a special sensor is provided on a mobile phone terminal, and a special signal previously defined by this sensor (power off When the indication signal is detected, the power of the wireless unit is automatically shut off and transmission of radio waves is stopped. It also discloses resuming power supply to the wireless unit when the sensor does not detect a power off instruction signal. The power off instruction signal is sent from a special transmitter installed in the restricted use area.

 Disclosure of the invention

 Problem that invention tries to solve

 According to the prior art disclosed in Patent Document 1, only the original wireless communication function (function to communicate with the base station of the mobile phone) of the mobile phone terminal is considered. It is designed to stop the transmission of radio waves in restricted use areas such as hospitals and aircraft.

 However, recent mobile phone terminals and personal digital assistants also have the function for performing short-distance wireless communication as described above, so even within the restricted use area, Radio waves to carry out wireless communication of distance will continue to be emitted.

 [0008] Therefore, in the restricted use area, the user must manually operate to shut off all the power supplies of the terminal. However, when all the power of the mobile phone terminal is shut off, the radio wave for performing short distance wireless communication is also immediately stopped to be transmitted, so during short distance wireless communication with the other station. If there is, the other station will misunderstand that the mobile phone terminal has suddenly moved out of the communication area or that a communication failure has occurred, and the correct processing can not be performed.

 Further, the prior art as disclosed in Patent Document 1 does not stop transmission of radio waves from a mobile phone base station. However, when the remote station performing short-range wireless communication operates with the battery as a power source, the remote station also needs to suppress power consumption as much as possible. However, when the power of the mobile phone terminal is shut off and the radio wave from the mobile phone terminal is stopped, the other station which performs short distance wireless communication is short distance to restore communication with the mobile phone terminal. It is forced to repeat the transmission of communication radio waves and consumes unnecessary power.

[0010] In addition, even when the power supply of the terminal is shut off, radio waves are periodically transmitted to perform short-distance wireless communication with the other station. Furthermore, even within the restricted use area, When the power was turned off by the user's input operation with the power turned off, there was also the possibility that radio waves were temporarily transmitted.

 [0011] In addition, in the prior art, in order to regulate the use (transmission of radio waves) of the mobile phone terminal, special transmitters must be installed at each required place, and transmitters are installed. It is inevitable that the cost to manage

 According to the present invention, when a portable communication terminal such as a portable telephone terminal provided with a function of performing wireless communication with a partner communication terminal, for example, the user performs a predetermined power shut-off operation.

 In this embodiment, it is assumed that the present invention is applied to a wireless communication system as shown in FIG. The wireless communication system shown in FIG. 1 includes a mobile phone terminal 10, a short distance wireless communication device 20, and a base station 30.

 Similar to a general mobile phone, the mobile phone terminal 10 shown in FIG. 1 performs wireless communication (cellular wireless communication) with a nearby base station 30 providing communication service of the mobile phone. If necessary, secure communication lines necessary for calls and communications. In addition, the mobile telephone terminal 10 also has a function of predetermined short distance wireless communication, and the mobile telephone terminal 10 can perform short distance wireless communication with a short distance wireless communication device 20 existing in the vicinity. . Therefore, the short distance wireless communication device 20 also has a short distance wireless communication function.

 As a specific short-range wireless communication, for example, Bluetooth (registered trademark), IEEE 802.

Radio communication such as wireless communication (for example, wireless LAN), UWB (Ultra Wide B and, ultra-wide band wireless), Wireless USB (Wireless Universal Serial Bus, wireless USB), ZigBee (ZigBee), etc. compliant with 11 standards Wireless communication of 426 MHz band, wireless communication of 304 MHz band, etc. are assumed. Therefore, the radio frequency band and modulation format used in the short distance radio communication are different from the radio frequency band and modulation format used in the radio communication between the mobile phone terminal 10 and the base station 30. Also, the distance that can be communicated by short distance wireless communication It is short compared to cell phone wireless communications.

The contents of the detailed control of the short-range wireless communication control unit 13 will be described later, but the control will be as follows if it is briefly described.

 [0054] When a predetermined condition is satisfied, for example, when an input operation instructing to turn off the mobile phone terminal 10 is detected, the short-range wireless communication transmission unit 11 transmits a radio wave-off notification and then transmits the radio wave-off notification. The radio wave transmitted from the distance wireless communication transmission unit 11 may be turned off (in the same meaning, the expression “turn off the radio wave” or “turn off the radio wave” may be used in the same meaning). The same goes for "etc. In addition, when a predetermined condition is satisfied, for example, there is an input operation instructing the power-off of the mobile phone terminal 10 (that is, when the main power is off) and the power-on input operation is further detected. After turning on the radio wave transmitted by the short-range wireless communication transmission unit 11, the short-range wireless communication transmission unit 11 transmits a radio-wave on notification to the short-range wireless communication device 20. In addition, when the mobile phone terminal 10 detects that it has entered an area where transmission of radio waves for short distance radio communication is permitted, the radio wave transmitted by the short distance radio communication transmission unit 11 is switched from off to on. Then, the short-range wireless communication transmission unit 11 transmits a radio wave on notification.

Also, the trigger of the start of such control can be given from the power control unit 17.

The cellular radio communication transmitting / receiving unit 15 has a function for transmitting / receiving radio waves of cellular radio communication with the base station 30, as with the cellular radio communication transmitting / receiving unit of a general mobile phone. The cellular radio communication transmission / reception unit 15 can be configured by, for example, a high frequency circuit and an electric circuit including analog signal processing.

 The cellular radio communication control unit 16 has a function for controlling transmission and reception of the cellular radio communication transmission / reception unit 15 as well as a cellular radio communication control unit of a general mobile phone. The cellular radio communication control unit 16 needs to realize various functions such as processing of the communication protocol of the cellular radio communication, and, for example, is mainly configured by a digital circuit or a processor for signal processing and software. Various functions can be implemented using digital signal processing. Also, base station information or position information can be obtained from the base station 30 via the cellular radio communication transmitting / receiving unit 15.

 The power control unit 17 has a function for controlling the power on Z off or the operation state of each circuit constituting the mobile phone terminal 10. The power ONZOFF input unit 18 accepts an input operation by the user to instruct power on or off. The GPS receiving unit 19 receives radio waves from a plurality of satellites of GPS (Global Positioning System), and calculates the position of its own station on the earth by calculation.

 The operation of the power control unit 17 can be obtained, for example, from the power on / off input signal from the power on Z off input unit 18, obtained from the cellular wireless communication transmitting / receiving unit 15 through the cellular wireless communication control unit 16. It is assumed that power supply or operation of the circuit of each block of the mobile phone terminal 10 is controlled based on base station information or position information, position information from the GPS receiver 19 and the like. As one of such control, the start of various controls of the short distance wireless communication control unit 13 described above is to be triggered based on the obtained information.

On the other hand, with regard to the short distance wireless communication device 20, as shown in FIG. 1, the short distance wireless communication transmission unit 21, the short distance wireless communication reception unit 22, the short distance wireless communication control unit 23, and the reset input Department Prepare with 27 and beat.

 The short-range wireless communication transmission unit 21 transmits a radio wave of short-range wireless communication in the same manner as the short-distance wireless communication transmission unit 11 described above. Further, the short distance wireless communication receiving unit 22 receives a radio wave of short distance wireless communication in the same manner as the short distance wireless communication receiving unit 12 described above.

 The short distance wireless communication control unit 23 controls the short distance wireless communication transmitting unit 21 and the short distance wireless communication receiving unit 22 to control the operation of the short distance wireless communication. As one specific control, when the short-range wireless communication device 20 receives a radio-wave-off notification transmitted from the mobile phone terminal 10, the radio wave transmitted from the short-range wireless communication transmission unit 21 is turned off. Also, after receiving the radio wave off notification transmitted from the mobile telephone terminal 10 (ie, when the main power is off or the radio wave transmission is off), the radio wave from the mobile telephone terminal 10 is further transmitted. When the on notification is received, the radio wave transmitted from the short-range wireless communication transmission unit 21 is turned on. In order to realize various functions such as communication protocol processing at the time of control, it is assumed that the short-range wireless communication control unit 23 is mainly configured with a digital circuit or a signal processing processor and software. Ru. This allows digital signal processing to be performed.

 The reset input unit 27 is provided to reset the operation state of the short distance wireless communication control unit 23. For example, when the reset input unit 27 receives an input operation from the user and resets the operation state of the short distance wireless communication control unit 23, the operation state of the short distance wireless communication device 20 can be reset.

 A more specific operation of the system shown in FIG. 1 will be described below. The state transition regarding the operation of the mobile telephone terminal 10 and the short distance radio 20 constituting the system shown in FIG. 1 is shown in FIG.

As shown in FIG. 2, when the system of this form is in an initial state due to a power reset or the like, it passes through a predetermined search mode (step S 110) to enter the radio wave on mode (or radio wave transmission mode). ) (Step S120). The radio wave on mode means a mode (operating state) in which the mobile phone terminal 10 and the short distance wireless communication device 20 transmit and receive each short distance wireless communication. Note that transmission and reception operations in radio wave on mode are periodic (intermittent) transmission and reception for battery separation (reduction of power consumption). be able to.

 Then, when the predetermined conditions are met, the mobile phone terminal 10 turns off the radio wave transmitted from the short distance wireless communication transmission unit 11 after transmitting the radio wave off notification from the short distance wireless communication transmission unit 11. Then, the radio wave off mode (or radio wave transmission off mode, the same applies hereinafter) is transited (step S125). The radio wave off mode (step SI 30) means a mode in which the mobile telephone terminal 10 and the short distance wireless communication device 20 do not transmit their respective short distance wireless communication. However, the mobile phone terminal 10 and Z or the short distance wireless communication device 20 can receive short distance wireless communication even in the radio wave off mode. In addition, also regarding reception, periodic reception (intermittent reception) can also be performed for noticing.

Also, if the predetermined conditions are met, the radio wave transmitted from the short-range radio communication transmission unit is turned on, and then the short-range radio communication transmission unit power radio-wave on notification is transmitted and transition to radio-wave on mode is made. (Return) (Step S 135). In the following, these operations will be mainly described in more detail. Furthermore, in the following description, it is assumed that at least the short distance wireless communication device 20 performs short distance wireless communication reception in the radio wave off mode (step S130).

The process of the power supply control unit 17 of the mobile phone terminal 10 when the system shown in FIG. 1 also transitions to the radio wave off mode (step S 125) when the aforementioned radio wave on mode power also transitions to FIG. 3 is shown in FIG. As shown in FIG. 3, in the radio wave on mode, the power control unit 17 periodically checks an input signal from the power on Z off input unit 18 (step S201). If there is no power-off input signal that results in no power-off input operation, step S201 returns (step S202, NO). On the other hand, if there is a power-off input operation and there is a power-off input signal, the short-range wireless communication control unit 13 triggers the start of the communication sequence for transitioning from the radio wave on mode to the radio wave off mode. (Step S250) (step S202, YES).

 [0069] For example, when moving to a place where transmission of radio waves is restricted, such as in a hospital or in a plane, for transitioning from radio wave on mode to radio wave off mode according to an input operation from the user. A communication sequence is started.

The short distance between the mobile telephone terminal 10 and the short distance wireless communication device 20 is performed when the system shown in FIG. 1 also transitions to the radio wave off mode (step S125) as described above. The sequence of communication using wireless communication is shown in FIG.

 When receiving the trigger from the power supply control unit 17 described above, the short-range wireless communication control unit 13 of the mobile phone terminal 10 transmits a radio wave off notification from the short-range wireless communication transmission unit 11 as shown in FIG. Trust (Step S351).

 Next, when the short-range wireless communication control unit 23 of the short-range wireless communication device 20 receives the radio wave off notification from the mobile phone terminal 10 via the short-range wireless communication receiving unit 22, the short-range wireless communication control unit 23 The communication control unit 23 replies that the radio wave off notification has been received (S 352). After this reply, the short-range wireless communication control unit 23 turns off the radio wave transmitted from the short-range wireless communication transmission unit 21. That is, the short distance wireless communication device 20 stops the transmission from the short distance wireless communication transmission unit 21 and transitions to the radio wave off mode. In the radio wave off mode, the reception operation of the short distance wireless communication reception unit 22 is performed. Note that the reception operation can be periodic reception (intermittent reception) to perform symbol reception. (Step S391). In the radio wave off mode, the power supply of the short distance wireless communication transmission unit 21 can be turned off. Thus, in the short-range wireless communication device 20, the transition to the radio wave off mode (step S125) is completed.

 On the other hand, the short distance wireless communication control unit 13 of the mobile phone terminal 10 receives, via the short distance wireless communication receiving unit 12, a reply to the effect that the radio wave off notification from the short distance wireless communication device 20 has been received. Then, the short distance wireless communication control unit 13 turns off the radio wave transmitted from the short distance wireless communication transmission unit 11. That is, in the radio wave off mode, the mobile phone terminal 10 stops transmission of radio waves from the short distance wireless communication transmission unit 11. Then, the power control unit 17 turns off the power of the mobile phone terminal 10 (step S392). Thus, the mobile phone terminal 10 completes the transition to the radio wave off mode (step S125).

 In the power-off state of the mobile phone terminal 10 described here, the power supply to each circuit unnecessary for operation on the mobile phone terminal 10 is cut off, but, for example, the off state as in the receiving circuit. It is assumed that power supply to circuits that need to be operated during this period is either maintaining power or intermittently repeating power supply.

When the system shown in FIG. 1 transitions (returns) to the above-mentioned radio wave off mode power radio wave on mode (step S 135), the processing of the power supply control unit 17 of the mobile phone terminal 10 is shown in FIG. Ru.

 In the radio wave off mode, the power control unit 17 periodically checks the input signal from the power on Z off input unit 18 (step S 401). If the power on input signal is not detected, the process returns to step S401 (step S40 2 NO) o

 On the other hand, when the power-on input operation is performed and the power-on input signal is detected, the cellular radio communication control unit 16 is turned on (step S421) (step S402, YES). In this case, the cellular radio communication control unit 16 turns on the cellular radio communication transmission / reception unit 15 (step S422), and the base station information or position information from the base station 30 via the cellular radio communication transmission / reception unit 15 To receive. The received base station information or position information is notified to the power control unit 17 (step S423).

 Next, based on the base station information or the position information acquired from the base station 30, the power supply control unit 17 determines whether or not the regional strength for turning on the radio wave of the short distance wireless communication. Specifically, for example, information in each area indicating whether to transmit radio waves is registered in a table or the like, and the coordinates (latitude, longitude) of the current position or the number of the base station 30 are collated with the contents of the table. Thus, it is possible to identify whether or not to turn on the transmission of radio waves.

 Then, when it is not determined that the mobile phone terminal 10 has entered the area where the transmission of radio waves for short distance wireless communication is turned on (ie, in a place where the use is restricted), the radio wave off mode is maintained ( Step S483) (Step S424, NO). On the other hand, when it is determined that the mobile phone terminal 10 has entered the area where the transmission of radio waves for short distance wireless communication is turned on (that is, usage is not restricted, no problem in places), the short distance wireless communication control unit The 13 power supplies (or the function of the short distance wireless communication control unit 13) are turned on (step S425) (step S424, YES).

 Next, the power supply control unit 17 gives the short distance wireless communication control unit 13 a trigger for starting the sequence of communication for transitioning (returning) from the radio wave off mode to the radio wave on mode (step S440).

In steps S421 to S423, it is assumed that base station information or position information is received using cellular radio communication in order to obtain the current position. It can also be used to determine the current position. Therefore, the base station Instead of using 30, the GPS receiver 19 may be used to obtain position information.

When the system shown in FIG. 1 transitions (returns) to the above-mentioned radio wave off mode power radio wave on mode (step S 135), short distance radio communication between the mobile telephone terminal 10 and the short distance radio communication device 20 The communication sequence is shown in FIG.

When the short-range wireless communication control unit 13 of the mobile phone terminal 10 receives the trigger from the power supply control unit 17 described above, the short-range wireless communication transmission unit 11 power supply (or short-range wireless communication transmission unit 1 1 After turning on the transmission of radio waves), as shown in FIG. 6, a radio wave on notification is transmitted from the short-range wireless communication transmission unit 11 (step S551).

Next, when the short-range wireless communication control unit 23 of the short-range wireless communication device 20 receives the radio wave on notification from the mobile phone terminal 10 via the short-range wireless communication receiving unit 22, the short-range wireless communication control unit 23 The communication control unit 23 turns on the radio wave transmitted from the short distance wireless communication transmission unit 21 (or the power supply of the short distance wireless communication transmission unit 21). Therefore, after that, the short distance wireless communication device 20 can transmit the radio wave from the short distance wireless communication transmission unit 21. Then, the short distance wireless communication control unit 23 sends a reply indicating that the radio wave on notification has been received (S 552). Thus, in the short-range wireless communication device 20, the transition to the radio wave on mode (step S135) is completed.

 On the other hand, the short distance wireless communication control unit 13 of the mobile phone terminal 10 receives, via the short distance wireless communication receiving unit 12, a reply indicating that the radio wave on notification has been received from the short distance wireless communication device 20. Then, the mobile telephone terminal 10 is in a state of transmitting the radio wave from the short distance wireless communication transmission unit 11 (step S592). Thus, the transition to the radio wave on mode (step S135) is completed in the mobile phone terminal 10 as well.

 In the sequence of FIG. 6, for comparison with the sequences of the other embodiments, the power described as “return to the (normal) authentication mode” (S591, S592) It goes without saying that it is more accurate to say "return to radio wave on mode" if authentication has not been performed.

Further, in the above description, it is assumed that at least the short distance wireless communication device 20 can receive short distance wireless communication even in the radio wave off mode (step S130). However, in the radio wave off mode (step S 130), the short-range radio 20 Does not receive short-range wireless communication! Even if the short-range wireless communication control unit 23 is reset from the reset input unit 27 of the short-range wireless communication device 20, Distance The operating state of the wireless communication device 20 can be reset. In addition, by performing an input operation of power on from the power on Z off input unit 18 of the mobile phone terminal 10, the operation state of the mobile phone terminal 10 can be reset. In this case, the radio wave on mode (step S120) can be set after passing through a predetermined search mode (step S110).

 In the above description, it is assumed that short-distance wireless communication is performed between the mobile phone terminal 10 and the short-distance wireless communication device 20. However, the present invention is not limited to the mobile phone terminal 10. Even when the information terminal (PDA) performs short distance wireless communication with the short distance wireless communication device 20, the same operation can be realized.

 By using the system described above, transmission of radio waves of short distance wireless communication can be stopped under predetermined conditions. In addition, even if the user is not particularly aware, it is possible to stop transmission of radio waves for short distance wireless communication in conjunction with the power-off operation of the mobile phone terminal 10.

. Furthermore, in a place where the use is not restricted, it is possible to return to the state of transmitting radio waves of short-range wireless communication in conjunction with the power-on operation of the mobile phone terminal 10 without the user being conscious in particular. Furthermore, in places where use is restricted, transmission of radio waves for short-range wireless communication can be stopped in conjunction with the power-off operation of the mobile phone terminal 10 without the user being particularly aware.

 Second Embodiment

 Another embodiment relating to the mobile communication terminal and the wireless communication device, the mobile communication system, and the communication control method of the present invention will be described below with reference to FIGS. 7 to 10.

FIG. 7 is a block diagram showing a configuration example of a system in the second embodiment. FIG. 8 is a sequence diagram showing a control procedure for the system to shift to the radio wave off state in the second embodiment. FIG. 9 is a flow chart showing control when a power on operation of the mobile phone terminal is performed in the second embodiment. FIG. 10 is a sequence diagram showing a control procedure for returning the system to the radio wave on state in the second embodiment. The second embodiment is a modification of the first embodiment, and it is assumed that the present invention is applied to a wireless communication system as shown in FIG. In FIG. 7, elements corresponding to those of the first embodiment are indicated by the same reference numerals.

 The wireless communication system shown in FIG. 7 is composed of a mobile telephone terminal 40, a wireless key device 50, and a base station 30. Similar to a general mobile phone, the mobile phone terminal 40 shown in FIG. 7 performs wireless communication (cellular wireless communication) with a nearby base station 30 that provides a mobile phone communication service, as required. Secure communication lines necessary for calls and communications. The mobile telephone terminal 40 also has a function of predetermined short distance wireless communication, and the mobile telephone terminal 40 can perform short distance wireless communication with the wireless key device 50 existing in the vicinity. Therefore, the wireless key device 50 also has a short distance wireless communication function.

 The wireless key device 50 holds a unique ID code and the like, and is used for various authentications.

 For example, in the case where one wireless key device 50 to be possessed by a legitimate user exists in the vicinity of the mobile phone terminal 40 when using a specific function in the mobile phone terminal 40, the mobile phone terminal 40 and the wireless key device The user can use the functions of the mobile phone terminal 40 in order to successfully authenticate the ID code etc. However, when a third party who does not possess the legitimate wireless key device 50 uses the portable telephone terminal 40, the wireless key device 50 does not exist in the vicinity, so that the authentication is not successful and the portable telephone terminal 40 specific functions become unavailable.

 The cellular phone terminal 40 shown in FIG. 7 includes a short distance wireless communication transmission unit 11, a short distance wireless communication reception unit 12, an authentication control unit 14, a cellular wireless communication transmission / reception unit 15, and a cellular wireless communication control. A power supply control unit 17, a power ONZOFF input unit 18, and a GPS reception unit 19 are provided. That is, a major difference between the mobile phone terminal 10 shown in FIG. 1 and the mobile phone terminal 40 shown in FIG. 7 is that an authentication control unit 14 is provided instead of the short distance wireless communication control unit 13. The other components are the same as in the first embodiment.

The authentication control unit 14 of the mobile telephone terminal 40 has an authentication function in addition to the functions of the short distance wireless communication control unit 13 described above. That is, in the above-described radio wave on mode, wireless authentication is performed using short distance wireless communication with the wireless key device 50. Furthermore, based on the result of this authentication, the authentication control unit 14 restricts the functions of the cellular radio communication control unit 16 (for example, , Call control, etc.), and power control of the mobile phone 40 (eg, power on or off). Since the authentication control unit 14 also has the function of the short distance wireless communication control unit 13, the authentication control unit 14 can be regarded as a kind of short distance wireless communication control unit.

 On the other hand, the wireless key device 50 shown in FIG. 7 includes a short distance wireless communication transmission unit 21, a short distance wireless communication reception unit 22, an authentication control unit 24, and a reset input unit 27. That is, the big difference between the short distance wireless communication device 20 shown in FIG. 1 and the wireless key device 50 shown in FIG. 7 is that the authentication control unit 24 is provided instead of the short distance wireless communication control unit 23.

 The authentication control unit 24 of the wireless key device 50 has an authentication function in addition to the function of the short distance wireless communication control unit 23 described above. That is, in the above-described radio wave on mode, wireless authentication using short distance wireless communication is performed with the authentication control unit 14 of the portable telephone terminal 40. Note that various methods can be considered as a method of starting an authentication procedure. In this example, it is assumed that the authentication is started using a wireless signal periodically transmitted by the wireless key device 50 as a trigger.

 The specific operations of the mobile phone terminal 40 and the wireless key device 50 constituting the system in the second embodiment will be described below. In FIGS. 8 to 10, the steps corresponding to those of the first embodiment are indicated by the same reference numerals. Description of the same steps is omitted.

 Also in the system of the second embodiment, state transition is performed as shown in FIG.

 In the second embodiment, since radio authentication using short distance radio communication is performed in the radio wave on mode, in the following description, the radio wave on mode is also referred to as an authentication mode.

In the radio wave on mode (authentication mode), the authentication control unit 14 of the mobile phone terminal 40 and the authentication control unit 24 of the wireless key device 50 perform predetermined wireless authentication using short-range wireless communication. As for the contents of wireless authentication, it is assumed, for example, to exchange ID codes with each other and to confirm whether or not the ID code of the opposite station and the ID code of the own station are associated with each other. Then, when the authentication is established, the mobile phone 40 cancels the function restriction (for example, the calling restriction) of the cellular radio communication control unit 16 or the power control of the mobile phone 40 (for example, Power on, etc.). The specific wireless authentication procedure itself is the same even if other wireless authentication procedures are not limited to this example.

 When the system shown in FIG. 7 transits to the radio wave on mode power to the radio wave off mode (step S 125), the processing of the power supply control unit 17 of the mobile phone terminal 40 is the same as the contents shown in FIG. . Therefore, this explanation is omitted.

 When the system shown in FIG. 7 transitions to the radio wave on mode power to the radio wave off mode (step S 125), short distance wireless communication is used between the mobile telephone terminal 40 and the wireless key device 50 which is a short distance wireless communication device The sequence of communication is shown in Figure 8.

 The content of the sequence shown in FIG. 8 is that the portable telephone terminal 40 and the wireless key device 50 which is a short distance wireless communication device mutually transmit and receive notification that the radio wave off notification and the radio wave off notification have been received. , It is similar to the sequence shown in FIG. Further, in the sequence shown in FIG. 8, transmission / reception can be performed by adding a notification indicating that the radio wave off notification and the radio wave off notification have been received to the sequence for wireless authentication using short-range wireless communication (step S307). , S309, S312).

 As shown in FIG. 8, after the wireless key device 50 and the portable telephone terminal 40 mutually transmit and receive the notification that the radio wave off notification and the radio wave off notification have been received, the authentication control unit 24 of the wireless key device 50 The radio wave transmitted from the short distance wireless communication transmission unit 21 is turned off. That is, the wireless key device 50 does not perform transmission from the short-range wireless communication transmission unit 21. However, the reception operation of the short distance wireless communication reception unit 22 continues. Note that this reception operation may be periodic reception (intermittent reception) for battery saving. (Step S391). Thus, in the wireless key device 50, the transition to the radio wave off mode (step S125) is completed.

On the other hand, the authentication control unit 14 of the mobile phone terminal 40 turns off the radio wave transmitted from the short distance wireless communication transmission unit 11. That is, the mobile phone terminal 40 does not perform transmission of the short distance wireless communication transmission unit 11. Then, the power control unit 17 turns off the power of the mobile phone 40 (step S392). Thus, in the mobile phone 40, the transition to the radio wave off mode (step S125) is completed. In the power-off state of the mobile phone terminal 40 described here, the power supply to the main circuit blocks of the mobile phone terminal 40 is Power to Stop It is assumed that the power supply to some necessary circuit blocks, such as the receiver circuit, is maintained. Therefore, it is not possible to receive radio waves of short distance wireless communication even in the power off state.

 When the system shown in FIG. 7 transitions (returns) to the radio wave off mode power radio wave on mode (step S 135), the contents of the processing of the power control unit 17 in the mobile phone terminal 40 are shown in FIG. ing.

 In the process shown in FIG. 9, when there is an input operation of power on from the power on Z off input unit 18 and there is an input signal of power on, the power control unit 17 receives base station information. Alternatively, it is the same as the processing shown in FIG. 5 in that it is judged based on the position information whether or not it is an area where the radio wave of short distance wireless communication is turned on.

 The difference is that, in step S 453 of FIG. 9, the power supply control unit 17 gives the authentication control unit 14 a trigger to start the sequence transitioning (returning) to the radio wave on mode (authentication mode). After that, authentication is established, and it is a point to determine whether or not the force has returned to the authentication mode (step S461).

 When the authentication mode is restored (step S 461, YES), the authentication control unit 14 cancels the function restriction (for example, the call restriction) of the cellular radio communication control unit 16, and the power control unit 17 carries Power control of the telephone terminal 40 (for example, power on etc.) is performed (step S462).

 On the other hand, if the authentication mode is not restored! (Step S 461, NO) or if the area is not returned to the authentication mode (step S 451: NO), the user is requested to input the use restriction release password (step S480). Then, if the password is correct (step S 481, YES), the usage restriction is canceled (step S 482). If the password is not correct (step S 481, NO), the usage restriction is maintained (step S 481). Step S483).

 When the system shown in FIG. 7 transitions (returns) to the radio wave off mode power (also to the authentication mode) also in the radio wave off mode power (step S 135), the mobile telephone terminal 40 and the radio key which is a short distance radio communication device The sequence of communication with the device 50 using short range wireless communication is shown in FIG.

Note that the sequence shown in FIG. 10 is the same as the mobile telephone terminal 40 and the short distance wireless communication device. This is the same as the sequence shown in FIG. 6 in that the line key device 50 mutually transmits and receives notification that the radio wave off notification and the radio wave off notification have been received. Further, in the sequence shown in FIG. 10, it is possible to transmit and receive a radio authentication sequence using short-range wireless communication with a notification that radio wave off notification and radio wave off notification have been received (step S534, S542 2).

 Further, in the sequence shown in FIG. 10, the authentication control unit 14 of the mobile phone terminal 40 receives the ID code of the wireless key device 50 or the radio wave ON notification via the short-range wireless communication transmission unit 11 until receiving the notification. The transmission of the ID code of the telephone terminal 40 is continued (steps S513 to S519). Then, when the authentication control unit 24 of the wireless key device 50 in the intermittent reception state receives and confirms the ID code of the mobile phone terminal 40, the wireless key device 50 causes the mobile phone terminal 40 to return to the power ON state. It can be recognized that there is (step S521). Then, the wireless key device 50 transmits the ID code of the wireless key device 50 or the radio wave ON notification via the short distance wireless communication transmission unit 21 (step S534). As shown in FIG. 10, as a result of transmitting and receiving the radio wave OFF notification and the notification indicating that the radio wave OFF notification has been received to the radio authentication sequence, if the authentication is established, the system proceeds to the authentication mode as described above. If it returns and authentication is not established, it will request the input of the password for releasing the usage restriction.

 In the above description, it is assumed that at least radio key device 50 performs radio wave reception processing for short distance wireless communication in radio wave off mode (step S 130). The operation is possible even if the short distance wireless communication of the wireless key device 50 does not perform the reception process in (step S130). In that case, the operation state of the wireless key device 50 can be reset by resetting the operation state of the short distance wireless communication control unit 23 from the reset input unit 27 of the wireless key device 50. In addition, by performing the power-on input operation from the power-on Z-off input unit 18 of the mobile phone terminal 40, the operation state of the mobile phone terminal 40 can be reset. In this case, the radio wave on mode (step S120) can be set after passing through a predetermined search mode (step S110).

Also, in the above description, the case where the mobile telephone terminal 40 and the wireless key device 50 communicate is described, but a similar mobile electronic device may be used instead of the mobile telephone terminal 40. Operation can be realized. According to the system described above, in addition to the effects described for the first embodiment, the following effects can be obtained. That is, in places where the use of radio waves is not restricted, the radio waves of short-range wireless communication are turned on in conjunction with the power-on operation of the mobile phone even without the user's particular awareness, and the usage restrictions etc. be able to. Furthermore, in places where the use of radio waves is restricted, in conjunction with the power-on operation of the mobile phone, the short-range wireless communication radio waves are not turned on, but the user is required to enter a password for releasing the usage restriction. It is possible to release the usage restrictions etc. at the same time.

 Third Embodiment

 Another embodiment relating to the mobile communication terminal and the wireless communication device, the mobile communication system, and the communication control method of the present invention will be described below with reference to FIGS. 11 and 12. FIG. 11 is a sequence diagram showing a control procedure for the system to shift to the radio wave off state in the third embodiment. FIG. 12 is a sequence diagram showing a control procedure for returning the system to the radio wave on state in the third embodiment.

 This embodiment is a modification of the second embodiment. Further, as in the second embodiment, it is assumed that the present invention is applied to the system having the configuration shown in FIG. The system configuration is the same as that of the second embodiment.

 Next, the operation of the system will be described. This embodiment is largely different from the second embodiment in that the authentication control unit 14 of the portable telephone terminal 40 starts an authentication operation triggered by a wireless signal transmitted. However, the other operations are substantially the same as those of the second embodiment.

 The state transitions of the mobile phone terminal 40 and the wireless key device 50 that configure the system are the same as in FIG. However, in the radio wave on mode, wireless authentication using short distance wireless communication is performed. Therefore, in the following description, the radio wave on mode may be referred to as the authentication mode.

In the third embodiment, in the radio authentication sequence using short-range wireless communication in the radio wave on mode (authentication mode), a mobile telephone terminal is used in contrast to the case of the second embodiment. The authentication signal is changed to start the authentication operation triggered by the wireless signal transmitted by the 40 authentication control units 14. For other operations, the system of the second embodiment It is almost the same as

 In addition, when the system of the third embodiment transits from the radio wave on mode to the radio wave off mode (step S 125), the process of the power supply control unit 17 of the mobile phone terminal 40 has already been performed. It is the same as the contents of FIG. 3 described. Therefore, this explanation is omitted.

 When the system of the third embodiment transitions to the radio wave on mode radio wave off mode (step S 125), a short circuit between the mobile telephone terminal 40 and the radio key device 50 which is a short distance radio communication device is performed. A sequence of communication using distance wireless communication is shown in FIG. For the sequence shown in FIG. 11, the authentication control unit 14 of the mobile phone 40 uses the signal to be transmitted as a trigger to perform the authentication operation (step S301). It is almost the same as the sequence shown in FIG.

 In addition, when the system transits (returns) from the radio wave off mode to the radio wave on mode (step S135), the processing of the power supply control unit 17 of the mobile phone 40 is the same as the processing of FIG. It is. Therefore, the description of this process is omitted.

 When the system of the third embodiment changes (returns) to the radio wave on mode (authentication mode) also in the radio wave off mode power (step S 135), the mobile telephone terminal 40 and the wireless communication device which are short distance radio communication devices A sequence of communication using short-range wireless communication with the key device 50 is shown in FIG.

 Regarding the sequence shown in FIG. 12, the point at which the authentication operation is started using the wireless signal transmitted by authentication control unit 14 of mobile phone terminal 40 as a trigger (step S 531) has been changed. It is almost the same as the sequence of FIG. 10 already described.

In the above description, it is assumed that at least the reception processing of the short distance wireless communication of the wireless key device 50 is performed in the radio wave off mode (step S130). However, in the radio wave off mode (step S130), the operation is possible even when the short distance wireless communication of the wireless key device 50 does not perform reception processing. In that case, the operation state of the wireless key device 50 can be reset by resetting the operation state of the short distance wireless communication control unit 23 by operating the reset input unit 27 of the wireless key device 50. . In addition, by performing the power-on input operation from the power-on Z-off input unit 18 of the mobile phone terminal 40, the operation state of the mobile phone terminal 40 can be reset. In this case, a predetermined search The radio wave on mode (step SI 20) can be set after passing through (step SI 10).

In the above description, it is assumed that short distance wireless communication is performed between the mobile telephone terminal 40 and the wireless key device 50, but instead of the mobile telephone terminal 40, a general mobile electronic device is used. The same operation can be realized by using an apparatus.

The system described above achieves almost the same effect as the system described in the second embodiment.

Fourth Embodiment

 Another embodiment of the mobile communication terminal and the wireless communication device, the mobile communication system, and the communication control method of the present invention will be described below with reference to FIGS. 13 and 14. FIG. 13 is a flowchart showing control of the mobile phone terminal for the system to shift to the radio wave off state in the fourth embodiment. FIG. 14 is a flowchart showing control of the mobile phone terminal for the system to return to the radio wave on state in the fourth embodiment.

 This embodiment is a modification of the first embodiment. Further, as in the first embodiment, it is assumed that the present invention is applied to the system having the configuration shown in FIG. The system configuration is the same as that of the first embodiment, but the operation of each part is changed. The changed behavior is described below.

 The short distance wireless communication control unit 13 of the mobile phone terminal 10 controls the short distance wireless communication operation of the short distance wireless communication transmission unit 11 and the short distance wireless communication reception unit 12. As one of the specific control, when it is detected that the mobile phone terminal 10 has entered the area (specific area) where the radio wave of the short distance radio communication is turned off or used frequency is changed, the short distance radio communication transmission unit 11. After transmitting the radio wave OFF notification or the change notification of the use frequency, etc., turn off the use of the radio wave transmitted from the short distance wireless communication transmission unit 11 or change the use frequency or the like. For example, detection of entry into a specific area based on base station information or position information obtained from the base station 30 via the cellular radio communication transmitting / receiving unit 15 or current position obtained using the GPS receiving unit 19 If you do, perform these processing.

In addition, when the predetermined condition is satisfied, the short distance wireless communication control unit 13 turns on the radio wave transmitted from the short distance wireless communication transmission unit 11 and then turns on the short distance wireless communication transmission unit 11. Send a notification. For example, after detecting that the mobile phone terminal 10 has entered the area where the radio wave of the short distance radio communication is turned off, and further detecting that the mobile phone terminal 10 has entered the area where the radio wave of the short distance radio communication is turned on. After turning on the radio wave transmitted from the short-range wireless communication transmission unit, the short-range wireless communication transmission unit transmits a radio-wave on notification. Also, the trigger of the start of such control can be given from the power supply control unit 17.

 Note that, as a typical example of entering an area (specific area) where radio waves of short distance wireless communication are turned off or used frequency is changed, it may be considered that the mobile phone starts roaming overseas. Therefore, it may be possible to perform these processing when it is detected that roaming has been started or ended.

 The power control unit 17 of the mobile telephone terminal 10 controls the power supply or operation state of each circuit block of the mobile telephone terminal 10. For example, each power source control unit 17 can obtain each of the cellular phone terminals 10 based on base station information or position information obtained also via the cellular radio communication control unit 16 and the position information from the GPS reception unit 19 or the like. Controls block power or operating conditions. As one of the control, it is possible to give a trigger of start of various control of the short distance wireless communication control unit 13 described above based on the information.

 The configuration and operation of the short distance wireless communication device 20 are substantially the same as in the first embodiment. However, as a new process, when the short-range wireless communication control unit 23 of the short-range wireless communication device 20 receives a notification of change in operating frequency etc. from the mobile phone terminal 10, the short-range wireless communication transmission unit 21 It is desirable to carry out a process to change the used frequency of the radio wave to be transmitted.

 Next, the operation of the system will be described. The state transition of the mobile telephone terminal 10 and the short distance wireless communication device 20 constituting the system is the same as the contents shown in FIG. However, although not shown, it is desirable to add a new state transition so that the radio wave on mode can be maintained after changing the radio wave usage frequency etc. when transmitting or receiving a change notification such as the operating frequency.

In the radio wave on mode, each of the mobile telephone terminal 10 and the short distance radio communication device 20 is used. The radio wave off mode (step S130) is a mode (operation state) in which the short distance wireless communication is transmitted and received. Don't do it!

The contents of the processing of the power supply control unit 17 of the mobile phone terminal 10 when the system of the fourth embodiment transits to the radio wave on mode power radio wave off mode (step S 125) are shown in FIG. 13. .

 As shown in FIG. 13, in the radio wave on mode, power supply control unit 17 receives base station information or position information obtained from cellular radio communication transmission / reception unit 15 via cellular radio communication control unit 16, GPS reception The position information from the unit 19 is periodically checked (step S221). If the power control unit 17 determines that the area is not to turn off the radio wave based on the information, the process returns to step S201 (step S222, NO). On the other hand, if it is determined that the power is off, the short distance wireless communication control unit 13 is triggered to start the communication sequence for transitioning from the radio wave on mode to the radio wave off mode (step S250). ) (Step S222, YES).

 Note that the process of the power supply control unit 17 of the mobile phone terminal 10 in the case of changing the operating frequency etc. is also the same. The power supply control unit 17 of the mobile phone terminal 10 is, in the radio wave on mode, base station information or position information obtained from the cellular radio communication transmission / reception unit 15 via the cellular radio communication control unit 16, position information from the GPS receiving unit 19, etc. Check regularly. If the power supply control unit 17 determines that the area to be used, such as the frequency to be changed, is not a region to be changed based on such information, the process returns to the process of periodically checking base station information or position information. On the other hand, if it is determined that the area to be used is changed, the short-range wireless communication control unit 13 changes the used frequency and the like, and triggers the start of the communication sequence for maintaining the radio wave on mode. give.

In addition, as a typical example of entering an area (specific area) in which radio waves of short distance wireless communication are turned off or used frequency is changed, it may be considered that the mobile phone starts roaming overseas. Therefore, when it is detected that foreign roaming has been started (or when it is detected that the roaming destination has been changed), the short distance wireless communication control unit 13 also changes the radio wave on mode to radio wave off mode. Trigger the start of the sequence of communication to It is also possible to Similarly, when it is detected that foreign roaming has been started or ended, the short distance wireless communication control unit 13 can be triggered to start the sequence of communication for changing the frequency used, etc. .

 Also in the fourth embodiment, the short distance wireless communication between the mobile telephone terminal 10 and the short distance wireless communication device 20 when the system transitions to the radio wave on mode power radio wave off mode (step S125). The sequence related to communication using is similar to the content of FIG. 4 described above. Therefore, the description is omitted.

 It should be noted that, for the sequence of communication using short distance wireless communication between the mobile phone terminal 10 and the short distance wireless communication device 20 in the case of changing the operating frequency etc., the radio wave OFF notification shown in FIG. Instead, a use frequency change notification may be sent. Also, instead of the notification indicating that the radio wave off notification has been received, a notification may be sent indicating that the operating frequency change notification has been received.

When the system of the fourth embodiment transits (returns) to the radio wave off mode power radio wave on mode (step S 135), the process of the power supply control unit 17 of the mobile phone terminal 10 is shown in FIG. It is done.

 Power supply control unit 17 periodically determines base station information or position information obtained from cellular radio communication transmission / reception unit 15 via cellular radio communication control unit 16 and position information from GPS reception unit 19 in radio wave off mode. (Step S411).

 If the power control unit 17 determines that the area is not to turn on the radio wave based on the information, the process returns to step S411 (step S412, NO). On the other hand, if it is determined that the area is to be turned on, the short-range wireless communication control unit 13 is turned on (step S440) (step S412, YES). Trigger the start of the sequence of communication to transition to the radio on mode (step S440).

 Specifically, for example, information for each area indicating whether to transmit radio waves is registered in a table on the power control unit 17 or the like, and coordinates (latitude, longitude) of the current position or the number of the base station 30 By checking the contents of the table, the power control unit 17 can identify whether or not the radio wave should be turned on.

[0149] In addition, the area where the radio wave of short distance wireless communication is turned off or the frequency used is changed (specified As a representative example of entering the area (1), the case where the mobile phone terminal 10 starts overseas roaming of the mobile phone communication network can be considered. Therefore, when it is detected that roaming has ended (or when it is detected that the roaming destination has been changed), the short-range wireless communication control unit 13 transitions to the radio wave off mode power to the radio wave on mode. Can be controlled to trigger the start of the communication sequence to

[0150] Also, with regard to the processing from step S411 to step S412 in FIG. 14, it is assumed that base station information or position information is acquired from base station 30 using cellular radio communication. Instead of using the GPS receiver 19 to obtain current position information.

 Also in the system of the fourth embodiment, when transitioning from radio wave off mode to radio wave on mode (restoration) (step S 135), between mobile phone terminal 10 and short distance wireless communication device 20 The communication sequence using short-range wireless communication is the same as the contents of FIG. 6 described above. Therefore, the description is omitted.

 In the above description, it is assumed that at least the short-range wireless communication device 20 performs short-range wireless communication reception in the wireless-wave off mode (step S130). In the off mode (step S130), the operation is possible even if the short-range wireless communication device 20 does not receive short-range wireless communication. In that case, the operating state of the short distance wireless communication device 20 can be reset by resetting the operating state of the short distance wireless communication control unit 23 from the reset input unit 27 of the short distance wireless communication device 20. In addition, by performing the power-on input operation from the power-on Z-off input unit 18 of the mobile phone terminal 10, the operation state of the mobile phone terminal 10 can be reset. In this case, the radio wave on mode (step S120) can be set after passing through a predetermined search mode (step S110).

 Further, in the above description, although it is assumed that short distance wireless communication is performed between the mobile phone terminal 10 and the short distance wireless communication device 20, a general mobile phone is used instead of the mobile phone terminal 10. Similar operations can be realized using electronic devices.

As described above, in the system of the fourth embodiment, radio waves of short distance wireless communication can be turned off under predetermined conditions. In addition, areas where mobile phones turn off radio waves for short-range wireless communication or change frequencies, etc., even if the user is not particularly aware The radio wave of short-range wireless communication can be turned off in conjunction with entering (for example, start of overseas roaming etc.). Furthermore, even if the user is not particularly aware of the fact that the mobile phone has entered the area (specific area) where the radio wave of short-distance radio communication is on (for example, the end of overseas roaming etc.) Radio waves of distance wireless communication can be turned on.

Fifth Embodiment

 Another embodiment relating to the mobile communication terminal and the wireless communication device, the mobile communication system, and the communication control method of the present invention will be described below with reference to FIGS. 15 and 16. FIG. 15 is a flowchart showing control of the mobile phone terminal for the system to shift to the radio wave off state in the fifth embodiment. FIG. 16 is a sequence diagram showing a control procedure for the system to shift to the radio wave off state in the fifth embodiment.

 This mode is a modification of the second embodiment. Further, as in the second embodiment, it is assumed that the present invention is applied to the system having the configuration shown in FIG. The system configuration is the same as that of the second embodiment, but the operation of each part is changed. The changed behavior is described below.

 In this embodiment, as shown in FIG. 7, the authentication control unit 14 of the mobile phone 40 controls the short distance wireless communication of the short distance wireless communication transmitter 11 and the short distance wireless communication receiver 12. The outline of the specific control of the authentication control unit 14 is as follows.

 For example, when it is detected that the mobile telephone terminal 40 has entered an area (specific area) where off of radio waves of short distance wireless communication or change in used frequency is made, the short distance wireless communication transmission unit 11 After transmitting the radio wave OFF notification or the used frequency change notification, the authentication control unit 14 controls to turn off the radio wave transmitted from the short distance wireless communication transmission unit 11 or change the used frequency or the like.

 As a specific example, the base station information or position information obtained from the base station 30 via the cellular radio communication transmitting / receiving unit 15 or the current position obtained by using the GPS receiving unit 19 can be obtained by: These processes are performed when it is detected that a specific area has been entered.

When the predetermined condition is satisfied, after the radio wave transmitted from the short-distance wireless communication transmission unit 11 is turned on, the short-range wireless communication transmission unit 11 transmits a radio-wave on notification. concrete In addition, after detecting that the mobile phone terminal 10 has entered the area for turning off the radio wave of short distance radio communication, it is further detected that the mobile phone terminal 10 has entered the area to turn on the radio wave of short distance radio communication. In this case, after the radio wave transmitted from the short distance wireless communication transmission unit 11 is turned on, the short distance wireless communication transmission unit 11 transmits a radio wave on notification to the wireless key device 50. The trigger of the start of such control can be given from the power supply control unit 17.

 As a typical example of entering an area (specific area) where radio waves of short distance wireless communication are turned off or used frequency is changed, it may be considered to start overseas roaming of mobile phones. Therefore, when it is detected that foreign roaming has been started or ended, the above process can also be started using it as a trigger.

 Authentication control unit 14 performs wireless authentication using short-range wireless communication with authentication control unit 24 of wireless key device 50 in the radio wave on mode. Further, based on the result of this authentication, the authentication control unit 14 performs function restriction (for example, calling restriction) of the cellular radio communication control unit 16 or power control of the mobile phone 40 (for example, power supply And so on).

 The power supply control unit 17 of the mobile telephone terminal 40 controls the power supply or operation state of each circuit block of the mobile telephone terminal 40. For example, the power supply control unit 17 may use the mobile station 40 based on base station information or position information obtained from the cellular radio communication control unit 16 and the position information from the GPS reception unit 19 or the like. Control the power supply or operating status of each block. Specifically, it is assumed that the start of various controls of the authentication control unit 14 is triggered based on the information acquired from the base station 30 or the GPS reception unit 19, for example.

 The operation of the wireless key device 50, which is a short-distance wireless communication device, is substantially the same as that of the second embodiment. However, when the authentication control unit 24 of the wireless key device 50 receives, as a new process, a notification of change of the operating frequency etc. from the mobile phone terminal 40, the operating frequency of the radio wave transmitted from the short distance wireless communication transmission unit 21. It also performs processing to change etc.

Next, the specific operation of the system will be described. The state transitions of the mobile phone terminal 40 and the wireless key device 50 constituting the system are the same as the contents of FIG. 2 already described. It is. However, in the radio wave on mode, since wireless authentication is performed using short distance wireless communication, in the following description, the radio wave on mode may be referred to as an authentication mode.

 The sequence relating to wireless authentication between the mobile telephone terminal 40 and the wireless key device 50 is the same as that of the second embodiment, and various sequences may be used as needed. .

 The contents of processing relating to the power control unit 17 of the mobile phone terminal 40 when the system of the fifth embodiment transits to the radio wave on mode power radio wave off mode (step S 125) is shown in FIG. 15. .

 With regard to the contents of the process shown in FIG. 15, in addition to the process in FIG. 13 already described, a process for giving a warning that the use restriction is to be implemented before shifting to the radio wave off mode (step S 223 )It is included. In addition, after the warning, unless the user cancels the wireless authentication, after the radio wave off mode transition is completed, usage restriction (for example, call restriction) of the mobile phone is started (step S282).

 [0169] When the system of the fifth embodiment transits to radio wave on mode radio wave off mode (step S125), communication using short distance radio communication between the mobile telephone terminal 40 and the radio key device 50 The sequence is shown in FIG. The contents of the sequence shown in FIG. 16 are the same as the sequence of FIG. 8 already described. Therefore, this explanation is omitted. After the transition to the radio wave off mode is completed, the usage restriction (for example, the calling restriction) of the mobile phone is started unless the user cancels the wireless authentication execution (step S394).

 The sequence shown in FIG. 8 or FIG. 16 is a sequence in the case of performing communication using short-range wireless communication between mobile phone terminal 40 and wireless key device 50 in the case of change of operating frequency or the like. Part of is changed as follows. That is, in the step of radio wave off notification in FIG. 8 or FIG. 16, the contents are changed so as to transmit the use frequency change notification. Also, in the step relating to the notification indicating that the radio wave off notification has been received in FIG. 8 or FIG.

Also in the system of the fifth embodiment, the processing of power control unit 17 of mobile phone terminal 40 when transiting (returning) from radio wave off mode to radio wave on mode (authentication mode) (step S 135) Is similar to the content of FIG. 14 already described. Therefore, its explanation Is omitted. It should be noted that after the radio wave on mode transition is completed, the usage restriction (eg, call restriction) of the mobile phone is released.

 Also in the system of the fifth embodiment, when transitioning from radio wave off mode to radio wave on mode (restoration) (step S 135), the mobile telephone terminal 40 and the wireless key that is a short distance wireless communication device The sequence of communication with the device 50 using short-range wireless communication is similar to the content of FIG. 10 described above. Therefore, the description is omitted. It should be noted that after the radio wave on mode transition is completed, the usage restriction (for example, the calling restriction) of the mobile phone is released.

 In the above description, it is assumed that at least the wireless key device 50 performs reception processing for short distance wireless communication in the radio wave off mode (step S 130), but the radio wave off mode (step S 130) In the above, even if the wireless key device 50 does not perform the reception process of the short distance wireless communication, the operation is possible. In that case, the operating state of the wireless key device 50 can be reset by resetting the operating state of the short distance wireless communication control unit 23 from the reset input unit 27 of the wireless key device 50. In addition, by performing an input operation of power on from the power on Z off input unit 18 of the mobile phone 40, the operation state of the mobile phone 40 can be reset. In this case, the radio wave on mode (step S120) can be set after passing through a predetermined search mode (step S110).

 Also, in the above description, it is assumed that short-range wireless communication is performed between the mobile phone terminal 40 and the wireless key device 50, but instead of the mobile phone terminal 40, a general portable electronic device is used. The same operation can be realized by using.

 [0175] By using the system as described above, mobile telephone terminal 40 enters an area (specific area) where off of radio wave of short distance radio communication or change of used frequency etc. (eg, roaming overseas) In conjunction with the detection of the start, etc., the radio wave of the short distance wireless communication can be turned off, and the usage restriction of the mobile telephone 40 can be implemented. Furthermore, in conjunction with the detection (for example, the end of overseas roaming etc.) that the mobile phone terminal 40 has entered the area (specific area) where the radio wave of the short distance wireless communication is turned on, even if the user is not particularly aware. The radio wave of the short distance wireless communication can be turned on, and the usage restriction of the mobile phone terminal 40 can be released.

 Sixth Embodiment

Mobile communication terminal and wireless communication device of the present invention, and portable communication system and communication Another embodiment of the control method is described below with reference to FIG. FIG. 17 is a sequence diagram showing a control procedure for the system to shift to the radio wave off state in the sixth embodiment.

 This form is a modification of the fifth embodiment. Further, as in the fifth embodiment, it is assumed that the present invention is applied to the system having the configuration shown in FIG. The system configuration is the same as that of the fifth embodiment, but the operation of each part is changed. The changed behavior is described below.

 Also in the sixth embodiment, the state transition regarding the portable telephone terminal 40 and the wireless key device 50 which constitute the system is the same as the contents of FIG. 2 already described. Also, the sequence of wireless authentication in the authentication mode (radio wave on mode) is the same as that of the third embodiment. Furthermore, the processing of the power supply control unit 17 of the mobile phone terminal 40 when the system transitions from the radio wave on mode to the radio wave off mode (step S 125) is the same as that of the fifth embodiment. Therefore, these explanations are omitted.

 [0179] When the system of the sixth embodiment transits to radio wave on mode radio wave off mode (step S125), the communication using the short distance radio communication between the mobile telephone terminal 40 and the radio key device 50 Most of the sequence is the same as the content shown in FIG. However, the point at which the first trigger is applied (step S301) differs depending on the radio signal periodically transmitted by the mobile phone terminal 40. After the transition to the radio wave off mode is completed, the usage restriction (for example, the call restriction) of the mobile phone is started unless the user cancels the setting of the wireless authentication (step S394).

 [0180] With regard to the sequence of communication using short-range wireless communication between mobile phone terminal 40 and wireless key device 50 in the case of change of operating frequency, etc., part of the sequence shown in FIG. 8 or FIG. It is changed as follows. That is, in place of the step of radio wave off notification shown in FIG. 8 or FIG. Also, instead of the notification step indicating that the radio wave off notification has been received, processing for transmitting a notification indicating that the operating frequency change notification has been received is performed.

When the system transits (returns) from the radio wave off mode to the radio wave on mode (authentication mode) (step S 135), the processing of the power control unit 17 of the mobile phone terminal 40 has already been described. It is the same as the contents of FIG. Therefore, the description is omitted. It should be noted that after the radio wave on mode transition is completed, the usage restriction (for example, the call restriction) of the mobile phone is released.

 In addition, when the system also transits (returns) the radio wave off mode power to the radio wave on mode (step S135), the short distance between the portable telephone terminal 40 and the wireless key device 50 which is a short distance wireless communication device The communication sequence using wireless communication is the same as the content of FIG. 12 described above. Therefore, the description is omitted. It should be noted that after the radio wave on mode transition is completed, the usage restriction (for example, the call restriction) of the mobile phone is released.

 In the above description, it is assumed that at least the wireless key device 50 performs reception processing for short distance wireless communication in the radio wave off mode (step S 130), but the radio wave off mode (step S 130) In the above, even if the wireless key device 50 does not perform the reception process of the short distance wireless communication, the operation is possible. In that case, the operating state of the wireless key device 50 can be reset by resetting the operating state of the short distance wireless communication control unit 23 from the reset input unit 27 of the wireless key device 50. In addition, by performing an input operation of power on from the power on Z off input unit 18 of the mobile phone 40, the operation state of the mobile phone 40 can be reset. In this case, the radio wave on mode (step S120) can be set after passing through a predetermined search mode (step S110).

 Also, in the above description, a system for performing short distance wireless communication between the mobile phone terminal 40 and the wireless key device 50 is assumed, but instead of the mobile phone terminal 40, a general mobile electronic device is used. The same operation can be realized even if it is used.

 [0185] According to the system described above, the mobile phone terminal 40 enters an area (specific area) where the radio wave of the short distance wireless communication is off or the operating frequency is changed (for example, start of overseas roaming etc.) The radio wave of short distance wireless communication can be turned off and the use restriction of the mobile phone terminal 40 can be implemented in conjunction with the detection of. Furthermore, even if the user is not particularly aware, it is linked to the detection of the mobile telephone terminal 40 entering an area (specific area) where the radio wave of short distance wireless communication is turned on (for example, the end of overseas roaming etc.). Then, the radio wave of the short distance wireless communication can be turned on, and the usage restriction of the mobile phone terminal 40 can be released.

The following control can be performed in any of the sixth embodiment described above. As conditions for turning off or turning on radio waves for short-range wireless communication, either mobile phone terminal 10 (or mobile phone terminal 40) or short-range wireless communication device 20 (or wireless key device 50) It can be added that the received signal level of the radio wave of the short distance communication received is equal to or higher than a predetermined value. Alternatively, the distance between the mobile telephone terminal 10 (or the mobile telephone terminal 40) and the short distance wireless communication device 20 (or the wireless key device 50) is predetermined as a condition for turning off or turning on the radio wave of the short distance wireless communication. Can be added within

Further, in the case of identifying the received signal level as a condition as described above, the threshold value of the received signal level (or distance) is set to different values when the radio wave is turned off and when the radio wave is turned on. It's a story, and it's the same value.

 For example, if the threshold of the received signal level (or distance) when turning off the radio wave is set to a signal level (far distance) weaker than the threshold of authentication of normal short distance wireless communication, the cellular phone terminal 10 The radio wave can be turned off even when the short distance between (or the portable telephone terminal 40) and the short distance wireless communication device 20 (or the wireless key device 50) is long. This makes it possible to more reliably prevent the emission of short-range radio waves in places where use is restricted. Conversely, if it is set to a signal level (close distance) that is stronger than the authentication threshold of normal short-range wireless communication, the probability of erroneously turning off the radio wave due to noise or the like decreases, or out of communication range while setting radio wave off. Can be reduced. As a result, radio waves can be turned off with few malfunctions.

[0190] Also, if the threshold of the received signal level (or distance) when turning on the radio wave is set to a signal level (close distance) stronger than the threshold of authentication for normal short distance wireless communication, noise or the like may occur. The probability of accidentally turning on the radio can be reduced, or the probability of being out of range during radio on can be reduced. As a result, radio waves can be turned on with less malfunctions. Conversely, by setting the signal level (far distance) weaker than the threshold of authentication of ordinary short distance wireless communication, radio waves can be turned on even when the short distance is far. This makes it possible to resume short-range wireless communication more quickly. In addition, when turning on the radio wave, as described above, it is controlled to turn on the radio wave after confirming that it is an area where the radio wave may be turned on using base station information or position information such as GPS. be able to. Industrial applicability

 As described above, the present invention is applied to a wireless communication system in which a portable wireless station such as a cellular phone terminal or a personal digital assistant (PDA) performs short distance wireless communication with another station. This makes it possible to temporarily stop the transmission of radio waves for short-range wireless communication and resume the transmission of radio waves. Moreover, when the transmission of the radio wave is stopped, the other station is notified prior to that, so efficient communication operation becomes possible.
