。In order to solve the above problems, in the present invention, the interval of intermittent reception can be controlled by a signal transmitted from a transmitting device. That is, the signal transmitted from the transmitter is composed of a synchronization signal, paging data, and intermittent reception control data, and the signal is repeatedly transmitted until the paging data is changed. The intermittent reception control data is data that specifies a time interval at which the receiving device performs intermittent reception.

を受信装置は行うことが可能となる。According to the transmission signal configuration of the radio paging system as described above, the receiving device can set the frequency of intermittent reception according to the received intermittent reception control data. That is, if the intermittent reception control data is data specifying the time interval of intermittent reception, the receiving device performs intermittent reception according to that value. In this case, the receiving device calculates the time from the value of the received intermittent reception control data to the start of cycle N, that is, the time when the intermittent reception control data switches from 1 to N, and continues receiving until the start of cycle N. Turn off the power to the circuit. If this cycle N is arbitrarily set on the transmitting side, the receiving device can perform intermittent reception corresponding to the cycle N.
