Abstract
A battery saving radio paging signal transmitting and receiving system includes an exchange for receiving a call request from a given terminal. I response to the call request, the exchange transmits a call message to a radio paging transmitter to enable communication with a radio paging receiver. The radio paging transmitter receives and encodes the call message to generate a call signal, and determines whether a subscriber corresponding to the radio paging receiver is a local area service subscriber or a wide area service subscriber based on a radio paging number provided in the call message. The radio paging transmitter initially transmits the call signal in a non-inverted state when the subscriber is a local area service subscriber, and initially transmits the call signal in an inverted state when the subscriber is a wide area service subscriber. The radio paging receiver adjusts an operating power source to activate one of a batch mode and an idle mode in accordance with the inversion and non-inversion of the call signal received from the radio paging transmitter.
