ステムの単信通信制御方法。2. The method according to claim 1, wherein, when the radio base station receives a transmission request signal from the transmission-side radio mobile station, information indicating that simplex communication is performed is added to the transmission request signal.
The first to sixth steps described above are executed, and when information for performing simplex communication is not added to this transmission request signal,
The process between the radio base station and the control station device is performed by assigning different identification codes to the originating radio mobile station and the terminating radio mobile station, respectively. A simplex communication control method for a digital mobile communication system, wherein different channel designation signals are wirelessly transmitted to a station and a called-side wireless mobile station.
