PURPOSE:To relieve the effect of disturbance due to an external wave by allowing a mobile station receiving notice of a radio wave interference due to an external wave with respect to an incoming control channel to vary the access period using the incoming control channel or to increase number of recycle circuits. CONSTITUTION:A signal is sent/received by using a control channel between a mobile station 3 and plural radio base stations 2 (21-23) and the mobile station 3 uses an incoming control channel when the station 3 makes access at calling and reply at the arrival of a call. In this state, when an external wave is received through the incoming control channel and a base station 2 detects a radio wave interference, then the presence of a radio wave interference is informed through an outgoing control channel from the base station 2 to the mobile station 3, the mobile station 3 receiving the notice varies the access period using the incoming control channel or increases number of recycle circuits. Thus, the effect of disturbance due to an external wave is relieved. |
