PROBLEM TO BE SOLVED: To obtain the personal handy phone system in which its power supply is interrupted automatically during high speed movement, power supply is restored automatically when the high speed movement is finished and the system restores to a communication available state by providing a detector detecting number of times of rewrite of a plurality of base station identification signals and a timer circuit operated at a prescribed time interval. SOLUTION: When the personal handy phone system (terminal) 1A moves at a high speed, the terminal sequentially receives a trigger pulse (Tr) and a plurality of different base station identification signals (CS-ID) within a prescribed time interval to rewrite sequentially the CS-IDs stored in a memory circuit 7b. A controller 7A integrates the Tr at an integration circuit 7d, activates a timer circuit 7c whose time is set by a restoration time setting device 11, interrupts power to a telephone circuit device 6 when the controller 7A detects a rewrite number of times of the CS-IDs, and when the CS-ID is unchanged within the set restoration time, the controller 7A activates the power supply to restore the terminal to be a communication available state. Thus, the terminal equipment 1A is realized, in which the power supply is automatically interrupted at high speed movement. |
