PURPOSE:To simplify the channel changeover during talking around the service area when a mobile station is subjected to control by two control stations in one radio zone. CONSTITUTION:A channel changeover exclusive zone is provided around the service area. The service areas S1, S2 are controlled respectively by control stations MCC1, MCC2. When the mobile station M2 starts its talking from a radio zone RZ11 and going to a radio zone RZ22 and the station enters a channel changeover exclusive zone RZH11 through the radio zone RZ11, the talking is continued by the talking channel changeover. In such a case, it is not required to provide any special line or control means between the control stations MCC1 and MCC2. In this example, since the station is already within the radio zone RZ22 when the talking is finished in the channel changeover exclusive zone RZH11, the outgoing/incoming call through the control station MCC2 is attained. |
