Paging system with message possible for communication between paging slave sets

Abstract

Abstract PURPOSE:To attain 2-way communication between paging slave sets by using a separate radio channel for a paging signal and a call request signal. CONSTITUTION:When a paging slave set 1b desires to call a paging slave set 1a, a call request signal is sent while being superimposed on a radio wave of CH2. The call request signal is received by an antenna 4b and a reception section 3b of a nearby paging master set and sent to a paging call reception device 6. The paging call reception device 6 decodes a paging call request signal and sends the call signal to the paging slave set 1a and the reception confirmation signal to the paging slave set 1b to a paging encoder device 5. The signal encoded by the paging encoder 5 is sent from transmission sections 2a-2c of a paging master set as a paging signal in the form of radio wave CH1.
