However, in the case of a telephone call mode provided by NTT DOCOMO, the call charge is higher than in the case of a voice call mode in which a normal voice-only call is performed. If it is better to make a call while watching, in order to make a call in the video phone mode for a while and hope for one of the users in the middle of the call, to reduce the call charge for the subsequent call, There is a method of switching from a video call mode with a high call charge to a voice call mode with only a low call charge and continuing the call.

  In addition, when there is a need for a switching operation from the voice call mode to the video phone mode, which is opposite to the switching operation from the voice call mode to the voice only voice call mode described above, for example, a voice only call In situations such as when you want to know where the other party's facial expression or clothes are, or where the other party is, you may not be able to understand the mode. In this case, switch from the voice call mode to the videophone mode. This is very convenient, and it is possible to continue the call by switching to the videophone mode from the middle of the call in the voice call mode.

  The operation for switching the call mode as described above is performed by the user who is making a call. However, as in the technique described in Japanese Patent Laid-Open No. 2001-54085, the user can switch the call mode. Techniques have also been developed to eliminate the need for operations. In this technology, when the receiver of the mobile terminal is brought close to the ear, the state detection means built in the mobile terminal automatically determines that the use state of the mobile terminal is in a call state using the receiver and automatically sets the call mode. Switch to the voice call mode, and conversely, when the mobile terminal is moved away from the ear, the use state of the mobile terminal is determined to be a call state using a speaker, and the call mode is automatically switched to the videophone mode. Configured mobile terminals have also been developed.

  FIG. 8 shows a case where the user performs a switching operation between the video phone mode and the voice call mode, and the conventional general mobile phone switches from the video phone mode to the voice call mode. A flowchart showing the flow of the operation of the mobile phone is shown.

  The switching operation of the call mode of the portable terminal in the conventional videophone service shown in FIG. 8 temporarily ends the connection of the call line connected in the videophone mode and ends the call up to that point (step S301). In the voice call mode to be switched, by performing a re-call by dialing the call partner up to that time (step S302), waiting for reconnection of the call line with the mobile terminal of the call partner (step S303), The telephone line is reconnected to the other party's mobile terminal, the reconnection is completed, the switching of the telephone mode from the video telephone mode to the voice telephone mode is completed, and the voice telephone can be entered (step S304). ) That is, in order to switch the call mode, it is necessary to once terminate the connection of the call line and perform a re-call by dialing to the other party in the call mode to be switched again.

  Conversely, when switching from a voice call mode call to a video phone mode call, it is necessary to reconnect the call line by making a call by redialing the call partner.
