Abstract
A paging network is disclosed which utilizes a plurality of distributed switches to transmit pages on a non-real time basis to achieve efficient and low cost transmission. Each of the switches processes packets of pages received from the network. Each of the switches also processes pages into packets of pages to be transmitted to another switch in the network or into batches of pages to be transmitted by a local paging service if the switch is a local switch. The network dynamically programs the reception channel(s) of the paging receivers in response to traffic conditons of a local switch or in accordance with service options specificed by a subscriber to a local paging service. The digits of the paging receiver identification code are transmitted in an order of increasing significance to conserve battery life of the paging receivers. Pages may be initiated by placing a local call to any lata switch in the network and service options may be varied by placing of a local call to a lata switch.
