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.

[ What is claimed is:] [1.] A battery saving radio paging signal transmitting and receiving system, comprising an exchange, a radio paging transmitter and a radio paging receiver;said exchange receiving a call request from a given terminal and, in response to said call request, transmitting a call message to enable communication with said radio paging receiver;said radio paging transmitter receiving and encoding said call message to generate a call signal, and determining whether a subscriber corresponding to said radio paging receiver belongs to a first group or a second group based on a radio paging number provided in said call message, said radio paging transmitter initially transmitting said call signal in a non-inverted state when the subscriber belongs to said first group and initially transmitting said call signal in an inverted state when the subscriber belongs to said second group; andsaid radio paging receiver adjusting an operating power source to activate one of a batch mode and an idle mode in accordance with the inversion and non-inversion of said call signal received from said radio paging transmitter;wherein, when said subscriber belongs to said first group, said radio paging receiver adjusts said operating power source to activate said batch mode during reception of said call signal in said non-inverted state, and adjusts said operating power source to activate said idle mode during reception of said call signal in said inverted state; andwherein, when said subscriber belongs to said second group, said radio paging receiver adjusts said operating power source to activate said batch mode for reception of said call signal in said inverted state, and adjusts said operating power source to activate said idle mode for reception of said call signal in said non-inverted state.
