In the system 10, the interval of an intermittent reception operation is further increased, so that a period of continuous standby time of a mobile station 15 increases and the power consumption of the mobile station 15 decreases. In operation, the mobile station 15 has a power source of its reception portion turned on in timed relationship with paging channels contained in a sending signal having been issued from a telephone exchange 12 to the mobile station 15 through a base station 14, and has the reception portion de-energized in the remaining period of time, so that the intermittent standby reception operation is performed. The exchange 12 sends a paging message in both an intermittent superframe reception group and a paging channel group, for which groups the mobile station 15 is waiting. The unit 15 receives broadcast information, specifies the intermittent superframe reception group on the basis of the contents of intermittent standby information contained in the broadcast information, and performs its intermittent standby reception operation in the reception group having been thus specified. |
