Assume that the power switch 2 is operated to turn off the power source 3. The power supply holding circuit 4 maintains the power supply 3 by operating the power switch 2.
power off (
(Input) Activate the information generation circuit 5. The power off (on) information generation circuit 5 generates power off information, then performs an automatic calling operation, and sends it to the nearest wireless base station 7 via the transceiver 6 along with its own subscriber number. Power supply holding circuit 4
The transmitter/receiver 6 is operated while the power cutoff information is being sent, and the power is turned off when the sending is completed. In the car telephone exchange 8, the subscriber number and power cutoff information are received by the information receiving device 9. The received information is analyzed by the central processing unit 10, and information that needs to be registered is registered in the storage device 11.

Next, when the calling party 12 makes a call request via the public network 13 to the mobile device 1 that has registered power disconnection, the central processing unit 10 receives the called party number sent from the calling party 12. The mobile device is analyzed and checked to see if it is a mobile device registered in the storage device 11. As a result, if it is determined that the mobile device is a registered mobile device, the information notification announcement device 14 is activated,
