PURPOSE:To reduce the zone blocking number by transmitting the schedule information of the call time from the mobile station to the fixed station, thus increasing the using efficiency of the circuit. CONSTITUTION:The radio communication zone is formed with base stations AS- KS which are arranged in series and controlled by control office MS, and the communication circuit is formed between plural number of mobile stations and office MS via the communication zone. And in case the communication zones of the communication circuits of plural number of communication zones which are adjacent to each other centering on the communication zone where the mobile station exists as well as that communication zone are blocked, the call scheduled time signal is transmitted from telephones TL1-TLn connected to link SLK of the mobile station via operation of keys F1 and Fn. The time signal transmitted is supplied to office MS via carrier end offices CEa-CEk of stations AS-KS. Thus the communication zone blocking number is decided, and furthermore the tracking is carried out for the mobile station via the call scheduled time signal. |
