PURPOSE:To eliminate an outgoing/incoming call reception disabling time of a mobile station by making a channel switching with the transmission of a channel switching signal during talking while systems are in talking. CONSTITUTION:Even when a mobile station 2 transits to a service area Y where systems A and B are overlapped while the mobile station 2 receives a channel for incoming control by the system A, the mobile station 2 conducts no system switching. On the other hand, the talking channel from the system A to the system B is switched by detecting the talking state of the mobile station 2 through the use of the talking channel of the system A by the outgoing or incoming connection in the area Y in the system. Thus, the mobile station 2 eliminates the outgoing/incoming reception disabling time through the level detection of the incoming control channel of the system B. |
