Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable radio telephone with reduced power consumption during a call.

[0002]

2. Description of the Related Art In recent years, portable telephones have been used in addition to voice calls.
It is also used for character information communication such as downloading from mail and contents. In this text information communication, there is a service in which a key operation of a terminal is performed according to voice guidance to download information. For example, when a key is operated in accordance with voice guidance to access a service of a predetermined trader, a desired song can be previewed or downloaded as a ringtone.

[0003] On the other hand, when these services are received by a conventional portable radio telephone device, both the transmission and reception circuits are connected in an operating state as in a normal voice call.
The unnecessary power consumption of the transmitting circuit is wasted.

[0004] A mobile radio communication device with reduced power consumption during transmission is disclosed in, for example, Japanese Patent Application Laid-Open No. 10-4380. In order to reduce the power consumption during transmission, it is sufficient that the audio information is not transmitted during the period from the silence start signal to the silence end signal. The zone is switched according to the electric field strength and the bit error rate of the control information. However, if there is no need to move, there is no need to send control information. Therefore, the transmission of control information is prohibited by operating the power saving mode changeover switch during a call. Specifically, the user operates the power saving mode switch to send a power saving mode switching request command to the exchange,
The exchange which has received this command returns a power saving mode switching instruction command. By receiving the power saving mode switching instruction command, the mobile radio communication device can recognize that the switching center has been switched to the power saving mode, and thus can prohibit transmission of control information thereafter. . On the other hand, even if the exchange enters the silent state and no radio wave comes from the mobile station, the line disconnection processing is not performed as long as the mobile station is in the power saving mode.

[0005] Applications other than voice communication are disclosed, for example, in Japanese Patent Application Laid-Open No. 9-325795. The communication device described in this publication includes a response message memory, and scrolls and displays a response message. Then, the selected response message is transmitted to the other party as a synthesized voice signal. Here, the response message is, for example, a fixed fixed number such as “Yes”, “No”, “Please give me again”. According to such a communication device, even in a public place such as a theater or a movie theater, or in a place where quietness is required such as a conference room, a call can be made without a voice.

[0006]

However, Japanese Patent Application Laid-Open No.
In the mobile radio communication device disclosed in Japanese Patent No. 4380, transmission power can be reduced, but power of a transmission circuit cannot be reduced.

Further, the communication device disclosed in Japanese Patent Application Laid-Open No. 9-325795 does not aim at reducing power consumption, and therefore cannot reduce the power consumption of the transmission circuit.

Accordingly, an object of the present invention is to reduce the power consumption of a cellular phone when making a call to a telephone number that does not require a two-way voice call.
