Abstract

A paging system is provided for transferring information to a paging receiver. The system includes a central controller having a paging controller, an encoder, and a first transmitter. The paging controller receives the information and data designating the paging receiver from an entry device. The encoder, in response to the data, generates a selective call paging signal designating the paging receiver. The selective call paging signal is transmitted to the paging receiver by the first transmitter. The paging receiver receives and decodes the selective call paging signal generating a control signal. A switching device is provided for selecting a normal and a deferred paging operating mode. In response to the control signal, a coded acknowledgment signal is generated indicating the selected paging receiver mode, and transmitted back to the paging controller by a second transmitter included in the paging receiver. A second receiver receives and detects the coded acknowledgment signal and in response to decoding the coded acknowledgment signal, the paging controller effects the transmission of the information to the paging receiver, which is stored in a memory when the paging receiver is in the deferred paging mode. When the coded acknowledgment signal indicates the paging receiver memory is full in the deferred paging operating mode, the information is stored in the central controller for transmission at a later time.
