Abstract

PURPOSE:To shorten a communication interruption time with regard to channel switching accompanying zone transition by testing the continuity of a new channel while holding communication over the last channel and switching the communication to the new channel on the completion of the continuity test. CONSTITUTION:A mobile equipment 9 has two transmitter and receivers 2 and 3 and a changeover switch 12. When the switching to a base station 7 is necessary while the mobile equipment 9 communicates with an equipment connected to a connection control network 8 through a base station 6 over a radio channel 4, the connection control network 8 acquires a radio channel 5 newly between the transmitter and receiver 3 and base station 7 while holding the communication over the channel 4. The continuity of this new radio channel 5 is tested, and when the continuity is normal, the switch 12 is changed over to the side of the transmitter and receiver 3. The connection control network 8 switches the communication path between the network and base station to the communication path between the network and the base station 7.
