[First Embodiment] FIG. 2 shows the operation of a mobile telephone having the configuration of FIG. 1 as a first embodiment. In the figure, S represents a step. First, the RSSI information is output from the receiving circuit 1 at the time of standby,
The SI information is input to the control circuit 3. When the RSSI information is equal to or less than a certain value, the control unit 3 causes the display unit 6 to display an out of service area. Then, the control unit 3 counts the time of the out-of-service display state (S101). When the out-of-service display time (out-of-service display time) exceeds an arbitrary time (set time) (S10)
2) A warning is issued to the user by the speaker 4 and the vibrator 5 (S103). If [arbitrary time> out-of-service display time] is determined in S102, an out-of-service standby is entered (S104). After the execution of S103, a screen is displayed to prompt the user to select one of the following messages: "Continue to display out of service area as is?" Or "Auto start after power off?" (S105). If the user selects “continue out-of-service display”, the mobile phone 10 continues the in-service display state (S106). On the other hand, if the user
If "Automatic start after F" is selected, a message prompting the user to set the restart time is displayed on the display unit 6, and the user inputs a time (restart time) until the automatic start is restarted after the power is turned off. (S10)
8). Thereafter, the power supply (at least for the communication system) is automatically turned off (S109). On the other hand, if the user
If no response is made to the display of No. 5 within a certain time, the power is automatically turned off (S107). This OFF
The state is continued until the user turns on the power.

When the time set in S108 elapses, the power is automatically turned on (S110). Next, it is determined whether any of the user's power ON / OFF operation, calling operation, and incoming operation has been performed (S11).
1). When it is determined that any operation is performed, the automatic start mode is released (S112). If the determination in S111 is NO and it is determined again that the vehicle is out of the service area (the second out-of-service area pattern), the counting of the out-of-service display time is started (S113). After that, the processing after S109 is repeatedly executed. In this case, the warning and the selection screen are not displayed, and the power is automatically turned off (S109).
An operation of restarting (S110) after the previously input automatic start time is executed.

According to the above-described embodiment, when the out-of-service state continues for a long time, the power can be automatically turned off and a warning can be issued to the user to inform the user that the out-of-service state is continuing. This allows the user to select whether to continue the out-of-service standby or to turn off the power and automatically turn on the power again after a time set by the user when the out-of-service state is determined to be prolonged. Become. Since the power supply to each circuit is stopped while the power is off, the battery consumption is suppressed, and the usable time of the mobile phone can be extended.

? And "Do you want to switch to single mode?" Are displayed, prompting the user to make a selection (S20).
3). If neither is selected within the fixed time, the process shifts to the single mode and waits (S204). Also,
If "Continue out-of-service display" is selected, an out-of-service standby state is set and the out-of-service display is continued (S205). Further, when “Single mode” is selected, a message prompting the user to set a restart time (arbitrary time) is displayed on the liquid crystal display of the display unit 6. When the user inputs the setting of the restart time according to this message (S206),
The mode shifts to the single mode (S207). Next, it is determined whether the single mode is out of the service area or in the service area (S20).
8) If the area is determined, the dual mode is activated after a set time, and a search for a standby channel is performed (S209). Next, it is determined whether or not the mobile station has gone out of the service area in the standby channel (S210). If the service area is in the service area, the mobile station performs standby in the dual mode (S212).
If it is out of the service area, the process returns to S207, and the subsequent processes are executed again.

On the other hand, when it is determined in step S208 that the terminal is out of the service area in the standby mode in the single mode, the mode shifts to the dual mode, the other mode in which the power is off is automatically activated, and the location is registered (S213). Here, the location registration refers to registering its own ID toward a base station in an area where the mobile phone 10 exists. Mobile phone 10
If is moved by a vehicle or the like, registration is performed again in a new area that is closer to the previous area.
Next, it is determined whether or not the dual mode is within the service area (S214). If it is within the service area, the standby mode is started in the dual mode (S215). Communication system) OFF (S
216), without performing location registration and communication with the base station.
When the set time has elapsed, the power is turned on (S
217). Thereafter, the process returns to S201, and the subsequent processes are repeatedly executed.

As described above, according to the second embodiment of the present invention, in a mobile telephone provided with a two-mode (PHS and mobile phone) communication mode, after detection of out-of-service, the mode shifts to single mode and the out-of-service mode is set. The power of the communication mode is set to OFF, and after switching to the single mode, after the set time, it is determined whether the dual mode is in or out of the service area. If the standby in the dual mode is possible, the standby in the dual mode is performed. Execute. Therefore, in the dual mode, the power supply on the stopped side is turned off, so that the consumption of the battery is suppressed and the usable time of the mobile phone can be extended.
