Abstract

A mobile telephone device comprises a separate paging signal channel in addition to the conventional transceiver channels which process voice signals. The paging signal channel has a lower power consumption level than the transceiver channels. A power supply control device shuts off power to the conventional transceiver channels when in a standby mode, i.e. when waiting for an incoming call, and applies power to the paging signal channel instead. Therefore, power consumption is reduced in the standby mode and consequently, the operating time of the battery is extended. Power is applied to the transceiver channels during voice communication periods. A calling party's telephone number received in the paging signal channel is stored and displayed. A control unit has the capability of immediately returning the calling party's call from the telephone number so stored and displayed. <IMAGE>
