Abstract
In a radio communication system (local radio system) having a plurality of radio cell stations (CS) and a plurality of radio personal stations (PS), when a certain radio personal station (PS) proceeds from a monitoring state to a call state, even during the call, the radio cell station (CS) of interest sends successively the information (slot and frequency information) which is required for the certain radio personal station (PS) to be returned back to the monitoring state to the certain radio personal station (PS) to be stored in the certain radio personal station (PS). By adopting such a procedure, when the call state has been quitted, even if the certain radio personal station proceeds once to a control channel, there is no need of obtaining the information required for the certain radio personal station to be returned back to the monitoring state. Since a time period for obtaining the information is not required, the transition from the call state to the monitoring state is immediately made.
