Or out of the service area where calls are not possible. If you are in the area, just turn on the power and it will be in the standby state,
When outside the service area, even if the power is turned on, the device does not enter a standby state, so that power is wasted.

[0004] When the power of the mobile phone 10 is turned off, the mobile phone 10 does not enter a standby state even in a service area.

[0005]

In the conventional portable telephone, only the display of "service area" where a call can be made or "out of service area" where a call cannot be made is performed. At that time, the power of the mobile phone was still turned on even in an area outside the service area, wasting power.

[0006] When the power of the mobile phone is turned on, "out of service area" is set.
If the power is turned off just because the display is displayed, the mobile phone does not enter the standby state even if the mobile phone enters the service area thereafter.

[0007]

In order to solve the above-mentioned problems, a portable telephone according to the present invention confirms location information inside or outside a service area at predetermined time intervals, and automatically turns off a power supply in an outside service area. It has a function to turn off. In addition, it has a function to automatically turn on the power when moving from outside the service area to the service area.

Used for comparison with the value of The display unit 108 displays “in range” or “out of range” based on position information obtained by wireless communication between the wireless communication unit 102 and the public wireless base station. The speaker 109 outputs, for example, a sound notifying that the user has entered the area within the service area from the service area or outside the service area during the movement.

Next, the operation of the present invention will be described with reference to the flowchart of FIG.

First, the power of the mobile phone 10 is turned on (200). On the display unit 108, "range" or "out of range" is displayed depending on the current position. Next, if the area is outside the service area, the input unit 107 inputs an input to start a mode for automatically turning off the power of the mobile phone 10 (hereinafter, referred to as a power saving mode).
(201).

When the power saving mode is started, the input unit 107 sets a time interval for confirming the position information within or outside the service area.
Is input (202). The input time is stored in the storage device 105, and the setting of the power saving mode ends at this stage. The first position information check is performed immediately after the setting is completed (203).

First, the operation when the first position information confirmation result is "in range" (204) will be described. In this case, the apparatus is in a standby state while the power is on. The clock 106 operates (205), and the standby state is maintained until the set time stored in the storage device 105 is reached.

At the set time, the second position information confirmation is performed (206). If the service area is in the “service area” again (207), the clock 106 operates in the standby state (20).
5). As described above, if the position information confirmation result is “in range”, the standby state is maintained. When the second position information confirmation result (206) is “out of service area” (208), the control unit 104 outputs a power-off command to the power supply circuit 103 (209), and the power supply of the mobile phone 10 is controlled. Is automatically turned off. The clock 106 operates even after the power of the mobile phone 10 is turned off (210).
