PURPOSE:To attain smooth call reception of a mobile set by varying optionally a time till a fixed station radiates a radio wave of a control channel when an incoming signal reaches from a telephone line. CONSTITUTION:When a incoming call signal reaches a fixed station 10 through a telephone line 1, an incoming call circuit 2 outputs an incoming detection signal to a radio control means 92. Upon the receipt of the incoming detection signal, the means 92 sends a setting code of a control channel to a frequency synthesizer 5 to activate a radio reception circuit 4, which discriminates whether a control channel is busy or idle depending on an output of an idle channel discrimination circuit 6. When the control channel is idle, the means 92 outputs a set signal of a timer means 91. After lapse of a time set in the means 91, the means 92 outputs a radio transmission circuit operating signal to activate a radio transmission circuit 3 thereby sending the control signal to a mobile set. The time from the incoming call detection till radiation of a control channel radio wave is optionally varied by presetting the time of the timer means 91. |
