MOBILE BODY COMMUNICATION SYSTEM

摘要

PURPOSE:To restrict the service area of other system in a service area of a communication system by integrating a mobile communication system in which radio zones are overlapped. CONSTITUTION:An exchange station 1-1 of an automobile telephone system 1 and an exchange station 2-1 of a mobile satellite communication system 2 have respectively home memories 1-1-l and 2-1-1 and are connected to a telephone network 4 and a common signal line network 5 to transmit and receive control information. When a reception level measurement section 7-5 of a mobile equipment 7 exclusively for the system 2 receives a radio wave from a base station 1-1 of the system 1 at a prescribed level, the reception of a call request from a transmitter-receiver 7-4 and an incoming call request from the base station via a transmitter-receiver 7-1 is stopped. A radio wave of a control channel is always set in the system 1 and the mobile equipment 7 exclusively for the system 2 implements the operation as above, then the use of the system 2 is restricted in the coverage area of the system 1.
