Description

  The present invention relates to a portable telephone system, a method for reducing power consumption in a portable telephone system, an external voice input / output device, and a portable telephone device. In particular, a user directly communicates with a communication partner using an external voice input / output device. The present invention relates to a portable telephone system to be performed, a method for reducing power consumption in a portable telephone system, an external voice input / output device, and a portable telephone device.

  In recent years, with the advance of technology, portable telephones that can be carried by users have become widespread.

  The portable telephone can apply a call service using IP (internet protocol) technology.

  As such a portable telephone, a portable IP telephone device using an IP network has been proposed (for example, see Patent Document 1).

  In this portable IP telephone apparatus, the portable IP telephone apparatus performs call control IP communication and voice data IP communication, and only the voice data is transferred to an external voice input / output apparatus.

  Here, as a specific example, an example of the portable IP telephone device is shown in FIGS.

  The portable phone system shown in FIG. 6 includes an external voice input / output device 100A, a portable IP phone device 200A, a wireless base station 300A, an IP network 400A, and a wireless LAN network 500A.

  The mobile phone system shown in FIG. 7 includes an external voice input / output device 100A, a mobile IP phone device 200A, and an IP network 400A.

  Here, the radio base station 300A shown in FIG. 6 is not limited to a radio base station, and may be a radio base station or a wireless LAN (local area network) access point that can be connected to the IP network 400A. good.

  The external audio input / output device 100A shown in FIG. 6 or FIG. 7 corresponds to a headset, earphone, or the like connected by wire, and shows a wireless part of the wired part.

  That is, as a wireless part of the wired unit, for example, a headset or an earphone using a Bluetooth (registered trademark) system.

  Here, the operation of the portable telephone system shown in FIG. 6 will be described. The portable IP telephone apparatus 200A communicates voice packets (voice data) and call control packets (call control data) with the radio base station 300A. It has become.

Furthermore, in the portable telephone system shown in FIG. 6, the portable IP telephone device 200A and the external voice input / output device 100A communicate with each other wirelessly via Bluetooth.
JP 2003-324517 A

  By the way, in the case of a call using the above-described external voice input / output device 100A, as shown in FIG. 6, the control of the telephone control protocol (call control) performed by IP communication and the voice communication connected by the call control are: The portable IP telephone device 200A is configured to perform this operation.

  That is, portable IP telephone apparatus 200A converts voice data into IP, changes the voice data converted to IP into an arbitrary format, and transmits it to external voice input / output apparatus 100A.

  For this reason, when this external voice input / output device 100A is used, since the portable IP telephone device 200A performs all the control, there is a problem that the portable IP phone device 200A consumes a large amount of power. It was.

  Here, the operation of this portable telephone system will be specifically described with reference to FIG. 8. In the portable telephone system shown in FIG. 6, the portable IP telephone apparatus 200A makes a call via the radio base station 300A. A connection request is made to the other party (steps S51 and S52).

  The other party is connected to the IP network 400A, and when receiving the connection request, returns an ACK to the portable IP telephone apparatus 200A via the radio base station 300A (steps S53 and S54).

  Next, when the portable IP telephone device 200A receives an ACK from the other party, the destination of the voice data is set to the portable IP telephone 200A to the other party that has returned the ACK, and a connection destination notification is sent to the wireless base station. Transmission is performed via the station 300A (steps S55 and S56).

  Upon receiving the connection destination notification, the communication partner transmits a connection destination notification for notifying the port that receives the voice data via the radio base station 300A (steps S57 and 58).

  Thereby, when portable IP telephone apparatus 200A acquires voice data from external voice input / output apparatus 100A (step S59), it transmits the voice data to the other party (step S60).

  When the other party transmits voice data, the other party sends voice data to the portable IP telephone device 200A (step S61), and the portable IP telephone device 200A sends the voice data to the external voice. The data is transmitted to the input / output device 100A (step S62).

  In this case, the voice data in steps S59 to S62 can be communicated as a call between the external voice input / output device 100A and the call partner via the portable IP phone device 200A.

  Then, when portable IP telephone apparatus 200A transmits a disconnection instruction to the call partner via radio base station 300A, the call is disconnected (steps S63 and S64).

  Thus, portable IP telephone device 200A transmits and receives audio data to and from the external voice input / output device 100A, so that power consumption increases.

  In particular, when the external voice input / output device 100A is wireless (for example, a Bluetooth headset), this problem is remarkable. For communication of voice data, the call partner and the portable IP phone device 200A, the portable IP phone device 200A and the external There is a problem that double power is consumed by the voice input / output device 100A.
