A wireless telephone system comprises a mobile station having its reception portion turned on in timed relationship with paging channels contained in a sending signal having been issued from a telephone exchange to the mobile station through a base station, and has the reception portion de-energized in the remaining period of time, so that the intermittent standby reception operation is performed. The exchange sends a paging message in both an intermittent superframe reception group and a paging channel group, for which groups the mobile station is waiting. The unit 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.
