  • transmitting an incoming call signal to a called radio subordinate unit through a radio transmission/reception portion of a radio interface unit by use of a control unit of a base station without performing an acquisition of a digital wire circuit communication channel between a radio control station and the base station when the base station receives a call setup message sent from the radio control station for the called radio subordinate unit through a circuit-control-channel control portion of a circuit interface unit, the call setup message passing through a digital wire circuit;

    acquiring the digital wire circuit communication channel between the radio control station and the base station by use of a communication channel management unit, at a moment at which it is known that the called radio subordinate unit is present in a radio area of the base station; and

    connecting the base station and the called radio subordinate unit through a radio communication channel after the acquisition of the digital wire circuit communication channel.
