1. A digital wireless telephone system comprising a mobile station provided with a reception portion, which portion is timed in its turning-on-power operation to a paging channel contained in a sending signal issued from a telephone exchange to said mobile station through a base station, and is held in its de-energized state in the remaining period of time, wherein when an intermittent standby operation is available, said telephone exchange sends out a paging message in an intermittent superframe reception group and in a paging channel group, for which groups said mobile station is waiting;

  • andwherein said mobile station receives broadcast information, specifies an intermittent reception group on the basis of the contents of intermittent standby information contained in said broadcast information, and performs its intermittent standby reception operation in said reception group having been thus specified, and wherein said intermittent standby reception operation reduces power consumption of said mobile station by arbitrarily controlling the interval of intermittent standby reception.
