PURPOSE:To suppress the generation of cross modulation by opening only a call channel not to give the cross modulation interference to a control channel for calling. CONSTITUTION:Idle channel information is held at areas ECH 1 to ECH 3 of an RMA, and a call channel is opened between handsets 1A to 1H based on the idle channel information. Further, when the idle channel information is registered to the areas ECH 1 to ECH 3, it is checked whether or not the call channel is a channel to give the cross modulation to a control channel, and when it is the channel to give the cross modulation, the registration to the areas ECH 1 to ECH 3 is prohibited. Thus, it is eliminated to give the cross modulation interference to the control channel, and in the base station 2, a command signal CMND can be correctly received. |
