  A user of a mobile communication terminal device may want to select a communication method according to a place or situation where communication is performed. For example, telephone calls are prohibited in trains and the like, and it is necessary to use e-mail, chat, and the like when communicating.

  However, in many cases, the calling user of the mobile communication terminal device cannot know in advance the location or situation of the called user. For this reason, the calling user may make a call regardless of the location or situation in which the called user is not allowed to make a voice call. In such a case, the called user cannot receive voice communication even though he / she recognizes the incoming call.

  As countermeasures that can be taken in such a case, conventionally, the calling party user can record the requirements using the message function, or the automatic answering message function can be used to notify the calling party user that the voice communication cannot be performed. There was a way to tell. When the message function is used, the called user can listen to the message by playing the recorded message. Even when the automatic response message function is used, the called user can identify the calling user from the caller display function of the mobile communication terminal device. Thus, a reply can be made by e-mail or voice communication.

  However, both of these methods have a drawback that they cannot respond to incoming calls in real time. In other words, the reply by voice communication cannot be performed until the voice communication of the called user is permitted. Also, in the method using e-mail or the like, since the calling user once replies after making a call, a certain time is required from the start of the incoming call to the reply.

  On the other hand, even in a place or situation where voice communication is possible, a user of a mobile communication terminal device may want to select a communication method or whether or not to allow a call. For example, during a meeting, if you have an urgent and complex requirement, you want to move outside the conference room to make a call, but if you need a simple response, e-mail or chat is more convenient. If you don't need it, you may not want to communicate.

  Even in such a case, since the calling user does not know the situation of the called user, there is a case where a call is made despite the requirement not worthy of voice communication. However, the called user cannot determine whether the requirement deserves voice communication unless he / she receives voice communication. For this reason, the called user is bothered by unnecessary voice communication.

  A first object of the present invention is to provide a technique for returning in real time to a calling side user without receiving the voice communication when the voice communication is received.

  A second object of the present invention is to apply a technique for determining the requirements of a calling user without receiving the voice communication when the voice communication is received.

Starting communication.

  In the first invention, it is desirable that the calling-side mobile communication terminal device transmits a display message to the called-side mobile communication terminal device when making a call.

  In the first invention, it is desirable that the called mobile communication terminal device automatically displays a display message on the display screen when receiving a call.

  Further, in the first invention, when the text conversation mode is selected, the text conversation communication is started after the automatic voice message notifying the selection of the text conversation mode is reproduced on the calling side mobile communication terminal device. It is desirable that

  (2) A mobile communication terminal device according to a second aspect of the present invention is an outgoing / incoming call means for performing call processing and incoming call processing related to voice communication with respect to another mobile communication terminal device, and another mobile communication terminal device. When a call signal is received, communication mode selection means for selecting either a voice mode or a text conversation mode based on a user's operation and, when the voice mode is selected, between another mobile communication terminal device And a communication connection means for starting character conversation communication with the other mobile communication terminal device when voice communication is started and the character conversation mode is selected.

  In the second invention, it is desirable that the incoming / outgoing call means transmits a display message to the other mobile communication terminal apparatus simultaneously with performing the outgoing call processing.

  In the second invention, when a call signal is received from another mobile communication terminal device, it is desirable to automatically display a display message received together with the call signal on the display screen.

  Further, the second invention starts character conversation communication after reproducing an automatic voice message notifying selection of the character conversation mode when the character conversation mode is selected by another mobile communication terminal device. Is desirable.

  According to the first and second inventions, the called-side user can select the communication by the text conversation communication for the call related to the voice communication, so without receiving the connection of the voice communication, A real-time reply can be made to the calling user.

  In addition, in the first and second inventions, when a call message is received, if a display message is transmitted from the calling communication terminal device to the called mobile communication terminal device at the time of outgoing call, In addition, it is possible to determine the requirements of the calling user without receiving the voice communication connection.

  Further, if this display message is automatically displayed on the display screen of the called-side mobile communication terminal device, the requirement can be easily determined.

  Further, when the text conversation mode is selected, if the automatic voice message notifying the selection of the text conversation mode is reproduced on the calling side mobile communication terminal device, the text conversation communication is started. The calling user can easily know that the text conversation mode has been selected.

  The housing 180 is used for housing other components 110 to 170.

  Next, a communication procedure when performing text conversation communication using the mobile phone terminal according to this embodiment will be described with reference to FIGS. Here, FIG. 3 is a sequence diagram for explaining the communication procedure, and FIG. 4 is a conceptual diagram showing a display screen example.

  (1) First, the user of the calling side mobile phone terminal operates the key input unit 150 to create a display message. The method for creating the display message may be the same as that for normal e-mail or mobile chat. At this time, the created display message is displayed on the display unit 140 and used for confirmation of the display message. Thereafter, the calling user operates the key input unit 150 to instruct transmission of a calling signal related to voice communication and the display message. The calling signal and the display message are transmitted from the control unit 130 to the transmission / reception unit 120, subjected to transmission signal processing, and transmitted from the antenna unit 110 (see a in FIG. 3).

  (2) The calling signal and the display message are sent to the called mobile phone terminal via a network (not shown). The calling signal and the display message are received by the antenna unit 110 of the called mobile phone terminal, subjected to signal processing by the transmission unit 120, and then sent to the control unit 130. In response to the reception of the calling signal, the control unit 130 notifies the incoming user of the incoming call using a ring tone, a vibration motor (not shown), or the like. At the same time, the control unit 130 sends the received display message to the calling user's telephone number (if the telephone number is registered in the called mobile phone terminal, the registered calling The user name may be displayed on the display unit 140 (see b in FIG. 3). FIG. 4 shows a display example at this time.

  (3) When the user on the called side presses the text conversation mode selection key 152 (see c in FIG. 3), the control unit 130 of the called mobile phone terminal receives the incoming call to the calling mobile phone terminal. Processing (sending a response signal to the calling signal, etc.) (see d in FIG. 3), and further, an automatic voice message notifying that the text conversation mode has been selected (for example, “This phone is received by the chat function. Message "or the like" is transmitted to the calling mobile phone terminal (see e in FIG. 3). Then, the controller 130 of the called mobile phone terminal starts a communication operation in the character conversation mode.

  (4) The calling side mobile phone terminal receives the automatic voice message from the antenna unit 110. The automatic voice message is signal-processed by the transmission / reception unit 120 and then sent to the control unit 130. The control unit 130 causes the speaker 170 to reproduce the automatic voice message (see f in FIG. 3). When the calling user recognizes that the called user has selected the text conversation mode by listening to the automatic voice message, the calling user presses the character conversation mode selection key 152 of the calling mobile phone terminal. (See g in FIG. 3). As a result, the control unit 130 of the calling mobile phone terminal also starts the operation of the text conversation communication.

  (5) Thereafter, text conversation communication is performed between the calling-side mobile phone terminal and the called-side mobile phone terminal (see h in FIG. 3). The procedure for ending communication is the same as that for ending in a normal mobile phone terminal. That is, if a predetermined call end key is pressed on either the calling side mobile phone terminal or the called side mobile phone terminal, the communication is ended.

  Next, a communication procedure when voice communication is performed using the mobile phone terminal according to this embodiment will be described with reference to FIG. Here, FIG. 5 is a sequence diagram for explaining the communication procedure.

  (6) First, as in the case of the text conversation communication, the user of the calling side mobile phone terminal creates a display message using the key input unit 150 and transmits it together with the calling signal (FIG. 5). I).

  (7) The called mobile phone terminal receives the calling signal and the display message in the same manner as in the case of the text conversation communication, notifies the called user of the incoming call, and displays the display message or the incoming message. A telephone number or the like is displayed on the display unit 140 (see j in FIG. 5 and FIG. 4).

  (8) At this time, when the called-side user presses the voice mode selection key 151 (see k in FIG. 5), the control unit 130 of the called-side mobile phone terminal Then, an incoming call process (transmission of a response signal to the call signal, etc.) is performed (see l in FIG. 5), thereby starting a communication operation in the voice mode (see m in FIG. 5).

  (9) The procedure for terminating the communication is the same as that for the text conversation communication.

  If the called user determines that the communication connection is not established as a result of confirming the display message displayed on the display unit 140 when the incoming call is received, the message function is used to satisfy the requirements as in the conventional case. It may be recorded, or the calling side user may be notified that voice communication cannot be performed by the automatic response message function, or may be left as it is.

  In this embodiment, the voice mode / character conversation mode is selected using the voice mode selection key 151 and the character conversation mode selection key 152. Instead, words such as “voice mode” and “character conversation mode” are used. May be displayed on the display unit 140, and the user may select a mode using the cursor key 153 and the enter key 154. FIG. 6 conceptually shows a screen display example of such a method. The user of the called-side mobile terminal device first operates the cursor key 153 to select, for example, “voice mode”. The display unit 140 displays the selected mode in black and white reversed. Then, when the called user presses the enter key 154, the selected mode is recognized by the control unit 130.

  In this embodiment, both voice communication and text conversation communication are performed by voice communication connection, but character conversation communication may be performed by data communication connection. In this case, for example, an automatic voice message notifying that the text conversation mode has been selected can be stored in an internal memory (not shown) of the calling side mobile phone terminal. That is, after making a data communication connection between the called mobile phone terminal and the calling mobile phone terminal, the control packet indicating that the character conversation mode is selected is sent from the called mobile phone terminal. If the calling mobile phone terminal that has transmitted to the mobile phone terminal and received this control packet plays the automatic voice message, it starts the text conversation mode without making any voice communication connection. Is possible.

  In this embodiment, the case where the present invention is applied to a mobile phone terminal has been described as an example, but it is needless to say that the present invention can also be applied to other mobile communication terminal devices such as a PHS and a car phone.

  As described above, according to this embodiment, the called user can select communication by text conversation communication for outgoing calls related to voice communication, so that without receiving voice communication, A real-time reply can be made to the calling user.

  In addition, in this embodiment, when a call is made, a message for display is transmitted from the caller communication terminal device to the callee mobile phone terminal. It is possible to determine the requirements of the calling user without performing communication.

  In this embodiment, since the display message is automatically displayed on the display screen of the called mobile phone terminal, an operation for confirming the display message is unnecessary. Therefore, the requirements can be easily determined and the operability is excellent.

  Further, when the text conversation mode is selected, the automatic voice message for notifying the selection of the text conversation mode is reproduced on the calling side mobile phone terminal, so that the text conversation communication is started. The person can know that the character conversation mode has been selected without checking the display screen. That is, according to this embodiment, as in the case of conventional voice communication, the caller only has to wait for the start of communication while the speaker 170 is in contact with the ear.
