[Description of operation of embodiment]
Next, the operation of the mobile phone system 200 showing an example of the present invention will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart showing an example of the basic operation of the mobile phone system 200 showing an example of the present invention. As described above, the mobile phone devices 204, 205, and 206 have the same configuration as the mobile terminal device 101 shown in FIG.

  In order to simplify the description of the operation of the mobile phone system 200, here, a PoC call is made from the mobile phone device 204 on the caller side to the mobile phone device 205 on the callee side, and from the mobile phone device 205 on the callee side, A case where PoC is made to the mobile phone device 204 will be described.

  As described with reference to FIG. 2, when the mobile phone device 204 on the calling side makes a SIP registration request to the mobile phone device 205 on the receiving side from the SIP server 201, the mobile phone device on the receiving side from the SIP server 201. Since the PoC incoming notification from the mobile phone device 204 is notified to the device 205, the incoming mobile phone device 205 receives the PoC incoming call from the SIP server 201 (step S401).

  The mobile phone device 205 on the receiving side that has received the PoC incoming call returns a PoC incoming call response indicating acceptance of the PoC incoming call to the SIP server 201 (step S402). The SIP server 201 that has received the PoC incoming response from the incoming mobile phone device 205 establishes a PoC communication session between the outgoing mobile phone device 204 and the incoming mobile phone device 205 (step S403).

  Here, for example, in the mobile phone device 205 on the receiving side, after the user of the mobile phone device 205 inputs the text for PoC speech into the text input frame 305 as shown in FIG. In step S404, the PTT button 302 of the operation unit 109 is pressed (step S405).

  When receiving the pressing operation of the PTT button 302, the control unit 102 of the incoming side mobile phone device 205 checks whether or not there is text input for PoC utterance (step S406). When there is text input for PoC utterance (YES in step S406), the text data for PoC utterance that has been input is analyzed in the text analysis unit 111 of the mobile phone device 205 on the incoming side (step S407). . Based on the analysis result analyzed by the text analysis unit 111, the text data is voice-synthesized by the TTS function in the data conversion unit 112 and generated as voice data (step S408). The generated voice data is transmitted to the calling-side mobile phone device 204 as voice data for PoC utterance in the called-side mobile phone device 205 (step S409).

  On the other hand, if there is no text input for PoC utterance in step S406 (NO in step S406), it is determined that PoC utterance is to be performed by voice, and the user's utterance voice is transmitted from the microphone 106 of the mobile phone device 205. Is received (step S410). The user's utterance voice received via the microphone 106 is transmitted as it is to the calling side mobile phone device 204 as PoC utterance voice data in the incoming side mobile phone device 205 (step S409).

  As described above, it is detected whether or not the user of the mobile phone device 205 on the receiving side has input a text for PoC utterance. By converting it and sending it as a PoC message to the mobile phone device 204 on the caller side, it is possible to suppress the transmission of useless voice data when no text is input.

  On the other hand, in the incoming side mobile phone device 205, when the PTT button 302 is pressed, there is no text input, and when a voice for PoC speech is input from the microphone 106, the user's voice input from the microphone 106 is displayed. Is transmitted as voice data of PoC speech as it is, when the user can speak PoC by voice instead of a public place, the user directly uses the microphone 106 without voice input. You can speak PoC.

  Note that FIG. 4 illustrates the case where the mobile phone device 205 on the receiving side speaks PoC, but the same applies to the case where the mobile phone device 204 on the calling side speaks PoC.

  In the embodiment shown in FIG. 4, as a method for determining whether or not text data is converted into voice data for PoC utterance, it is determined by whether or not text is input in the text input frame 305 when the PTT button is pressed. Although cases have been shown, the present invention is not limited to such cases.

  For example, whether or not the voice data for PoC utterance is converted from the input text data and acquired depending on whether or not the voice input suppression button that suppresses voice input is pressed when the PTT button is pressed. It may be determined whether the sound from the microphone 106 is used as it is. That is, the voice input suppression button is a button pressed by the user of the mobile phone device, and is a dedicated operation for designating either a PoC call by text input or a PoC call by the microphone 106 / speaker 107. Button. In addition, this voice input suppression button is shared with the manner mode button (a button for setting the sound output from the mobile phone device to the outside so as not to disturb the surroundings) provided in a normal mobile phone device. Thus, in a public place where the cellular phone device is set to the manner mode and used, PoC utterance itself due to voice input from the microphone 106 may be suppressed.

  Furthermore, the determination may be made using a combination of the presence / absence of text input and the pressed state of the voice input suppression button. For example, even when the voice input suppression button is not pressed, if the text is input in the text input frame, the input text is converted into voice data for PoC speech. On the contrary, even if the text is input in the text input frame, if the voice input suppression button is not pressed, the voice input from the microphone 106 is used for PoC speech. It may be used as audio data.

  Next, the operation when the voice data for PoC utterance is received will be described with reference to FIG. FIG. 5 is a flowchart showing another example of the basic operation of the mobile phone system according to the present invention, and shows an example of the operation when voice data for PoC utterance is received.

  In order to simplify the description of the operation of the mobile phone system 200, here, a case will be described in which the mobile phone device 204 on the caller side receives the voice data of the PoC message from the mobile phone device 205 on the callee side. . In addition, as a method of switching whether the received voice data for PoC utterance is output as voice or converted into text and output, the case where the voice output suppression button is pressed is determined.
