PURPOSE:To attain efficient calling of a mobile radio station by transmitting a power supply throw-in command and a power supply disconnection command of the mobile radio station to a radio base station and storing them in its storage section so as not to call the mobile radio station whose power is disconnected. CONSTITUTION:When an engine key 16 is turned off while a transmitter-receiver 12 is in operating state, it is informed to a controller 15, which transits a code representing the power supply disconnecting state and a mobile radio station number to a radio base station 18 from the transmittor-receiver 12. After a response signal representing that the radio base station 18 receives the said signal is received, a power switch 13 is turned off to interrupt the power to the transmitter-receiver 12. The power supply application and disconnection state are stored at each mobile radio station by a storage section 22 of the radio base station 18. When a call request to a movile radio station is incoming, the radio base station 18 reads the storage section 22 so as to check the state of power of each mobile radio station and does not conduct calling processing to a mobile radio station whose power is disconnected. |
