Abstract
When a base station of a digital radiotelephone system receives, through a circuit interface unit of the base station, a call setup message for a radio subordinate unit from a radio control station, an incoming call signal is transmitted to the radio subordinate unit through a radio interface unit of the base station, under control of a control unit of the base station, without performing an acquisition of a circuit communication channel between the radio control station and the base station. Thereafter, when a radio link setup message, an incoming call response, a call proceeding message or an authentication response message is provided by the radio subordinate unit, it is known that the radio subordinate unit is present in a radio area of the base station, and the circuit communication channel is acquired under the management of a communication channel management of the base station. Therefore, even when many incoming call signals are concentrated at the base station, a circuit communication channel can be reliably and efficiently acquired.
