Abstract

PROBLEM TO BE SOLVED: To provide a communication terminal that can prevent data of an image not scheduled by a user from being transmitted to a caller side. SOLUTION: When an incoming call indicates the arrival of image communication, a tone B is used for an incoming call notice (1st incoming call notice) (ST21). When a reply operation is made to the 1st incoming call notice (ST22), a display section displays (2nd incoming call notice) denoting the arrival of an incoming call by image communication, a channel to an opposite party (caller side) is connected, and a reply message is transmitted to the opposite party (ST28-ST30). When a reply is made with respect to the 2nd incoming call notice (ST31), the image communication is started (ST27). Since a preparation time until a 2nd reply is provided to a user, it is prevented that data of an image whose transmission is not scheduled by the user and obtained through image pickup by an image pickup section for example are transmitted to the caller side.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device suitable for application to, for example, a simple portable telephone. Specifically, when the communication type of the incoming call is image communication, the first
When the first response operation to the incoming call notification is made, a response message is transmitted to the calling side, and thereafter, when the second response operation to the second incoming call notification is made, the image communication is started, so that the user is scheduled. The present invention relates to a communication terminal device for preventing data of a missing image from being transmitted to a calling side.

[0002]

2. Description of the Related Art In recent years, portable telephones (PHS: Pers)
In the onal Handyphone System), voice communication (voice service) or image communication (image service) can be selected as the communication type. In voice communication, communication of voice data is possible. On the other hand, in image communication, communication of image data is possible.

[0003]

In image communication, image data can be transmitted as described above. Conventionally, when the communication type related to an incoming call is image communication, the image communication starts immediately when a response operation is performed to the incoming call notification. In this case, when a response operation is performed, for example, image data obtained by imaging by the imaging means attached to the PHS is immediately transmitted to the calling side, and data of an image not planned by the user is transmitted to the calling side. May be transmitted to the server.

Accordingly, an object of the present invention is to provide a communication terminal device capable of preventing data of an image not scheduled by a user from being transmitted to a calling side.

[0005]

A communication terminal device according to the present invention comprises: a judging unit for judging whether a communication type relating to an incoming call is image communication, a display unit for displaying at least an image, and a judging unit. When it is determined that the communication type related to the incoming call is image communication, a first incoming call notifying unit that performs a first incoming call notification and a period in which the first incoming call notification is performed by the first incoming call notifying unit First response control means for transmitting a response message to the calling side when there is a response operation to the caller;
When there is a response operation while the incoming call notification is being performed by the incoming call notifying means, the second incoming call notifying means for performing the second incoming call notification and the second incoming call notification are performed by the second incoming call notifying means. And a second response control means for starting image communication when a response operation is performed during the operation.

In the present invention, when there is an incoming call, it is determined whether or not the communication type related to the incoming call is image communication. When the communication type is image communication, a first incoming call notification is performed. For example, the first incoming notification is performed by a first notification sound different from the second notification sound used in the incoming notification when the communication type is not the image communication. Thereby, the user can confirm by the notification sound that the communication type is the incoming call of the image communication.

While this first incoming call notification is being performed,
When there is a response operation (first time) by the user, a response message such as “Please wait” is transmitted to the calling side. Thus, the calling side can confirm that the line connection with the other party has been established. For example, the response message is an image message, so that the calling side can visually confirm the response message.

Further, when the user performs a response operation as described above, a second incoming call notification is performed. For example,
The second incoming call notification is performed by displaying an image message (such as an image communication incoming call) on the display unit. This second incoming call notification may also be made by a notification sound.

While this second incoming call notification is being performed,
When there is a response operation (second time) by the user, image communication is started. For example, image data obtained by being imaged by the imaging means attached to the terminal device main body is transmitted to the calling side. As a result, the user performs a response operation (second time) after obtaining image data to be transmitted to the calling side, whereby image data not scheduled by the user is transmitted to the calling side. Can be prevented.

[0010] When there is no response operation by the user and the first incoming call notification continues for a predetermined time, an automatic response may be made and a message may be transmitted to the calling side. This message is, for example, an answering message and is for urging the calling side to transmit image data (voice data) to be recorded. This message is, for example, an image message, so that the calling side can visually confirm the absence response message.

Is used to store data generated under the control of the control unit 101 and as a working area.

Next, the operation of the PHS 100 shown in FIG. 1 will be described. Since the PHS 100 is out of synchronization with the control channel when the power is turned on, the PHS 100 receives the control channel transmitted from the base station and establishes synchronization with the control channel. In this case, control channels of available base stations are sequentially received, and the received signal strength (RSSI: Receive) is received.
A control channel of which signal strength is greater than or equal to the selected level and at the maximum level is selected, and synchronization with the control channel is established. Then, after that, location registration that the user is on the control channel for which synchronization has been established is performed. This location registration is performed using a call channel. After the location registration is completed, the mobile station returns to the reception state of the control channel for which synchronization has been established, and enters a standby state.

Next, the operation in the case of performing communication by the voice service or the image service will be described. For example,
In the PHS 100, when the telephone number of the other party is input by operating the keys of the operation unit 112, or when the call key is operated after searching the telephone directory data, a calling process is performed. In this calling process, the control unit 101 supplies the other party's telephone number data and the like as control data to the communication control unit 104 and transmits the data to the base station through a control channel. Then, as is well known, after a link channel is established and a call setting operation is performed, a line connection with the other party is performed, and a transition is made to a communicable state.

Also, call data is transmitted as control data from the base station using the control channel, and this call data is supplied from the communication control unit 104 to the control unit 101, and when an incoming call is detected, the incoming call processing is performed. Done. In this incoming call processing, as is well known, after the link channel is established and the call setting operation is performed, a response is made by operating the call key, so that the line connection with the other party is performed and communication is possible. Transition to the state.

Here, the communication is performed using the communication channel notified from the base station. In addition, as described above,
Whether to select voice communication (voice service) or image communication (image service) as the communication type is determined by the setting at the time of calling.

Transmission and reception when the communication type is voice communication will be described. The compressed voice data transmitted through the communication channel is output from the communication control unit 104. And
The compressed audio data is expanded by an audio processing unit 105 and further converted to an analog audio signal before being supplied to a speaker 106. As a result, the receiving sound is output from the speaker 106. On the other hand, an analog audio signal from the microphone 107 is converted into a digital signal by the audio processing unit 105, and after being subjected to compression processing, supplied to the communication control unit 104 and transmitted to the other party through a communication channel.

Next, transmission and reception when the communication type is image communication will be described. The operation at the time of reception will be described. For example, JPEG, QCI transmitted on the call channel
Compressed image data such as F, MPEG1, and MPEG2 is output from the communication control unit 104. Then, after the compressed image data is decompressed by the image processing unit 108,
It is supplied to the display unit 109. Thereby, the display unit 109
Then, an image based on the image data is displayed. On the other hand, the image data obtained by imaging by the imaging unit 110 is compressed by the image processing unit, supplied to the communication control unit 104, and transmitted to the other party through the communication channel.

Next, with reference to the flow charts shown in FIGS. First, in step ST1, it is determined whether there is an incoming call. If there is an incoming call, it is determined in step ST2 whether the communication type related to the incoming call is voice communication (voice service) or image communication (image service). If the communication type is voice communication, the incoming call is notified by the tone A from the ring tone output unit 111 in step ST3. here,
The tone means any one of a tone color, a pitch, a melody, a notification interval, and the like, or a combination thereof.

Next, in step ST4, it is determined whether or not there is a response operation by pressing the talk key. If there is no response operation, it is determined in step ST5 whether or not a predetermined time has elapsed since the incoming call. If the predetermined time has not elapsed, it is determined in step ST6 whether the incoming call has ended. If the incoming call has not ended, step S
Returning to T4, the same determination processing as described above is repeated.

In step ST6, when the incoming call ends,
It returns to step ST1. If there is a response operation in step ST4, a line with the other party is connected in step ST7, and voice communication is started in step ST8. Further, in step ST5, when a predetermined time has elapsed since the incoming call, the processing shifts to the answering machine processing. That is,
In step ST9, the line with the other party is connected, and in step ST10, an answering response message (voice data) is transmitted to the other party (calling side). This answering machine response message is for urging the other party to transmit voice data to be answering machine, and is stored in the nonvolatile memory 113 in advance as described above. Then, in step ST11, recording of a message (voice data) from the other party is started. This message is recorded in the nonvolatile memory 113.

Next, in step ST12, it is determined whether or not a predetermined recordable time has elapsed. If the predetermined time has not elapsed, it is determined in step ST13 whether or not the line of the other party has been disconnected. If there is no line disconnection on the other side, the process returns to step ST12 and repeats the same determination processing as described above. If the predetermined time has elapsed in step ST12, or if the line of the other party has been disconnected in step ST13, the recording of the message from the other party is terminated in step ST14.
At 15, communication termination processing is performed.

If it is determined in step ST2 that the communication type relating to the incoming call is image communication (image service), the process proceeds to step ST21 (FIG. 3) and the ringing tone output unit 1
From step 11, an incoming call is notified by tone B. This tone B
Is different from tone A in step ST3 described above. Thereby, the user can easily confirm whether the communication type related to the incoming call is voice communication or image communication by the tone in the incoming call notification at the time of the incoming call.

Next, in step ST22, it is determined whether or not there is a response operation by pressing the talk key. If there is no response operation, it is determined in step ST23 whether or not a predetermined time has elapsed since the incoming call. If the predetermined time has not elapsed, it is determined in step ST24 whether the incoming call has ended. If the incoming call has not ended, the process returns to step ST22 and repeats the same determination processing as described above.

When the incoming call is terminated in step ST24, the process returns to step ST1. Step ST22
If there is a response operation, the process proceeds to step ST25.
In this step ST25, it is determined whether the response is set to "response at the first time" or "response at the second time".
judge. By operating the operation unit 112 by the user,
The setting can be made arbitrarily. "Response at the first time"
Is set in step ST26, a line with the other party is connected in step ST26, and image communication is started in step ST27.

On the other hand, when "respond for the second time" is set, in step ST28, the display unit 109 displays, as an incoming call notification, an incoming call by image communication. The image data for this display is stored in the nonvolatile memory 113 in advance as described above. This call notification
If the incoming call notification in step ST21 is the first incoming call notification, the incoming call notification is a second incoming call notification.

Next, in step ST29, a line with the other party (calling side) is connected, and in step ST30, a response message is transmitted to the other party. This response message is an image message that displays an image such as "Please wait". The image data for the response message is stored in the nonvolatile memory 113 in advance as described above. As described above, since the response message is transmitted to the calling side, the calling side can visually confirm that the line connection with the partner has been established. Then, in a step ST31, it is determined whether or not there is a response operation by pressing the call key. If there is a response operation, the process proceeds to step ST27 to start image communication.

In step ST23 described above, if a predetermined time has elapsed since the incoming call, the processing shifts to the answering machine. That is, in step ST32, a line with the other party is connected, and in step ST33, the other party (calling side) is connected.
To send an absence response message (image data). This answering machine response message is for urging the other party to transmit image data to be answering machine, and is stored in the nonvolatile memory 113 in advance as described above. The other party can visually confirm the absence response message. Then, in step ST34, recording of a message (image data) from the other party is started. This message is recorded in the nonvolatile memory 113.

Next, in step ST35, it is determined whether or not a predetermined recordable time has elapsed. If the predetermined time has not elapsed, it is determined in step ST36 whether or not the line of the other party has been disconnected. If there is no line disconnection on the other side, the process returns to step ST35 and repeats the same determination processing as described above. If the predetermined time has elapsed in step ST35, or if the line of the other party has been disconnected in step ST36, the recording of the message from the other party is terminated in step ST37.
At T38, communication termination processing is performed.

As described above, in the present embodiment, when the communication type relating to an incoming call is image communication (image service) and "respond at the second time" is set, the first incoming call notification (step ST21) When the first response operation is performed for the second incoming call notification (step ST28), the image communication is started. . Therefore, the image communication is not immediately started by the first response operation, but a preparation time is given to the user until the second response operation is performed.
It is possible to prevent data of an image which is not planned by the user and is obtained by being imaged in 10 from being transmitted to the calling side.

In the above-described embodiment, the second incoming call notification performed in step ST28 (FIG. 3) is displayed on display unit 109, but may be performed using a notification sound.

In the above-described embodiment, the response operation in step ST22 (FIG. 3) and the step ST31
Although all of the response operations in FIG. 3 are performed by pressing the call key, each response operation may be performed by a different key.

In the above-described embodiment, when the communication type is image communication (image service), only the image data is communicated. Can be In that case, the message to be transmitted to the other party (calling side) can transmit a voice message together with or instead of the image message.

Further, in the above-described embodiment, the communication terminal device is a PHS. However, it goes without saying that the present invention can be similarly applied to other communication terminal devices.
