PURPOSE: To facilitate communication consecution (channel switching) processing through a common control channel of a transfer destination zone.
CONSTITUTION: When a mobile station 13 starts communication through a base station 121 of a zone 111, a base station stores a call management number to a home memory 22 by using a mobile station number as an address. When the mobile station enters a zone 11. and makes a re-connection request through a common control channel, a controller 162 receives the request through a base station 122 and accesses a home memory device 17 based on the mobile station number via an exchange 151 to recognize a resident zone 111 and a call management number and makes a switching request to a controller 161 of the zone 111 together with the call management number. The controller 161 makes a switching request to the exchange 151 similarly to the case with usual channel switching based on the call management number. The succeeding processing is processed similarly to the case with a conventional method and a new channel is designated to the mobile station via a base station 122.
