Description

Wireless call information display method and text information input method using infrared communication

The present invention adds an infrared transceiver to a pager, stores a large amount of messages such as life information received through the pager in a storage device, and then displays a terminal such as an electronic notebook or a computer or a personal terminal (PAD) equipped with an infrared transceiver. The present invention relates to a method of displaying a large amount of radio call information for transmission and display using infrared communication, and vice versa.

Figure 1a is a block diagram of a conventional text radio call network using a text radio pager.

In general, there are four methods for transmitting a text message using a wireless call network, which will be described below with reference to FIG. 1A.

In the first method, when the operator 12 verbally receives a message from the caller and inputs it into the text message system 13 using the telephone 11 and the public telecommunication network 11, the input message is transmitted to the radio call terminal 14. It is a manual text service method that is converted into a radio call message through the base station 15 and transmitted to the subscriber.

In the second method, when a caller inputs a desired message using the personal computer 16, it is transmitted to the text message system 13 connected by the modem 17, and the transmitted message is transmitted through the radio calling terminal 14. The automatic text service method is converted into and transmitted to the subscriber through the base station 15.

In the third method, when a caller dials a calling number using an electronic telephone and enters a pre-arranged fixed character code into the paging terminal 14, the entered message is transferred to the paging message through the paging terminal 14. It is a fixed sentence method that is converted and transmitted to the subscriber through the base station 15.

Lastly, the fourth method transmits the living information to the wireless calling terminal 14 from the living information database computer 18 in which the living information received from the information provider such as stock information, breaking news, and weather is stored. After converting the message into a broadcast information via the base station 15 to the subscriber to the life information service method.

Figure 1b is a block diagram of a conventional number radio call network using a number radio pager.

As shown in FIG. 1B, when the caller inputs a message through the telephone 10 and the public communication network 11, the input message is converted into a radio call message at the radio call terminal 14. It is transmitted to the called party 20 through the base station 15. As described above, the conventional digital radio call message transmission method lacks various services because only numeric telephone number messages can be transmitted between individuals.

In addition, since one of the features of the wireless pager is one-to-many communication, the living information service is suitable for the wireless calling system. However, the conventional text information receiving wireless pager mainly communicates between individuals, thus requiring portability. In case of receiving a large amount of messages as in the case of the display, the display unit is usually 7 characters in 2 columns, which is not suitable for viewing a lot of contents, and since the function page of the pager is usually less than 5, it is difficult to edit the received contents. It was inconvenient and not enough memory to get more life information services.

In addition, in the conventional text radio call service as described above, in order to receive a text message composed of Korean, English, numerals, etc., a number radio caller must be provided to receive a text radio call service. There was a problem.

Wireless communication terminals such as cellular phones and personal communication terminals having a conventional electronic organizer function have the disadvantage of increasing the size of wireless communication terminals, which are smaller in size when both numeric and character keys are installed to input the electronic organizer function. Installed or spoken. However, when inputting by voice, there was a problem that the accuracy is poor.

In order to solve the above problems, the present invention, by adding an infrared transceiver to the number or letter wireless pager, a large number of messages such as life information received through the wireless pager in the storage device electronic notebook equipped with an infrared transceiver Or a method of displaying a large amount of wireless call information for transmission and display to a display terminal such as a computer or a personal terminal (PAD) using infrared communication, and transmitting numerical and text information to the wireless communication terminal using infrared communication in an electronic notebook. The purpose is to provide a method of inputting character information.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

FIG. 2A illustrates an example of a text wireless call network using a general wireless pager equipped with an infrared transmitter and receiver to which the present invention is applied, and four text message transmission methods described in the related art may be used in the same manner.

In this case, the general pager 20 refers to a number wireless pager as well as a text wireless pager. Even when the general pager 20 is a number wireless pager that cannot receive text service, the wireless pager 20 includes an infrared transceiver. When the text is received later, the text message is received and stored in the storage device of the pager 20 equipped with the infrared transceiver. When the text message is requested to be sent from the electronic organizer 30 or another display terminal such as a computer or a personal terminal. By using infrared communication, a text message is transmitted to the electronic notebook 30 or a computer or a personal terminal, so that the transmitted text message can be viewed on the electronic notebook 30 or a computer or a personal terminal.

By adding an infrared transceiver to the general number wireless pager as described above, it is possible to receive text service from the general number wireless pager by infrared communication with other display terminals. That is, a wireless pager with an infrared transceiver displays a small number of wireless call information directly on the display, but when a large amount of life information is received, it is only temporarily stored in a storage device and transmitted to another display terminal through an infrared transceiver. And display devices with a large storage capacity and a large number of function keys. In terms of the development of wireless pagers, the development of high-speed transmission allows more messages to be transmitted and the pagers become smaller, so that pagers display only urgent or short messages and long messages appear on the display of the pager. Since it is not suitable, infrared transmission to other display terminals will lead to the development of a suitable device according to the development of high-speed transmission of a pager.

2b is another exemplary diagram of a text radio call network using a general radio pager equipped with an infrared transmitter and receiver according to the present invention.

As shown in Figure 2b by adding an infrared transceiver to the general pager 20, it is possible to send and receive wireless call messages with other terminals (electronic notebook, computer, personal terminal, etc.) equipped with an infrared transceiver, even in the number radio call service (10) and through the public telephone network (11) by inputting a fixed character code through the wireless call terminal 14 to the desired form of wireless call service to the general pager system 20, securities information, The living information service which receives the breaking news, the weather, etc. from the living information database computer 18 which stores and receives the breaking news, the weather, etc. is stored in the radio call terminal 14, and transmits to the subscriber.

3 is an example of a connection relationship using infrared communication between the pager and the electronic notebook according to the present invention.

The general pager 20 receives a radio frequency (RF) receiver 22 for receiving a radio call message from the base station 15 of the radio call network through the antenna 21, and receives the received radio call message from the high frequency receiver 22. Decoder 23 for receiving and decoding a radio call message of its own, a central processing unit 24 for receiving a radio call message from the decoder 23 and performing various processes and controlling each component; A storage unit 27 for receiving and storing a radio call message from the central processing unit 24, a display unit 25 for receiving a short radio call message from the central processing unit 24 for display by a user, and And a plurality of radio call messages temporarily stored in the storage unit 27 under the control of the central processing unit 24 when the electronic notebook 30 transmits the radio call message transmission request. An infrared transceiver 26 for transmitting to the infrared transceiver 31 is provided.

On the other hand, the electronic notebook 30 requests the infrared transceiver 26 of the pager 20 to transmit the radio call message, and receives an infrared transceiver 31 for receiving a large number of radio call messages, and inputs a user's command. A central processing unit 32 for processing a wireless call message input from the infrared transceiver unit 31 according to a command input from the key input unit 33, a key input unit 33 for receiving and controlling each component; A storage unit 34 for receiving and storing a radio call message from the central processing unit 32, and a display unit 35 for receiving and displaying a radio call message from the central processing unit 32 for viewing by a user. It is provided.

4 is a flowchart illustrating a data transmission method using infrared communication between a pager and an electronic notebook according to an embodiment of the present invention.

First, an electronic notebook with an infrared transceiver 31 in a state in which a general pager 20 having an infrared transceiver 26 stores a large amount of wireless call information (life information, etc.) received through a wireless call network. When requesting transmission of radio call information from (30) (41, 42), the general pager 20 generates a transmission start signal and transmits it to the electronic notebook 30 (43) and then starts transmission from the electronic notebook 30. Upon reception of a response signal to the signal (44), transmission of radio call information is started.

In the present invention, the transmission of radio call information is performed by dividing all radio call information into blocks (1 block = 128 bytes) and then transmitting from the first block (45) and receiving a response thereto (46). Wireless call information is transmitted until the last block (47 to 52).

Thereafter, the general pager 20 transmits an end signal to the electronic notebook 30 (53), and receives an answer signal for the termination signal from the electronic notebook 54 (54) to terminate all infrared communication processes.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

The present invention as described above has the following effects.

First, in order to receive a wireless call text service, the caller must have a wireless pager for receiving text information, but in the present invention, after receiving and storing a text with a wireless pager for receiving a text service, the display is different from an infrared transceiver. By transmitting and displaying to the terminal, it is possible to receive a wireless call text service even with a wireless pager for receiving numbers.

Secondly, in the case of wireless paging service, a large amount of wireless paging message is received, but because the display part of the existing paging device is small enough to display only seven characters on two lines, the paging device is not suitable for displaying a large amount of information. After receiving and storing the radio call information, a simple message is displayed on its own display, and a large amount of messages are transmitted to another terminal through an infrared transceiver, so that the user needs processing in a terminal having a larger screen, more storage capacity, and many function keys. By making it possible to print out, the user's convenience can be greatly improved.
