Abstract

A cooperative paging system (10) and radio telephone system (15) combine to provide conventional delivery of short paging messages to a combination pager/radio telephone (40) via a first communication path, while a radio telephone link operating at a higher data rate is used to deliver large data messages to the pager/radio telephone (40). The radio telephone link is formed by a transceiver section (205) of the pager/radio telephone (40) coupling to a radio telephone base station (50,52) and calling up a paging terminal (32) of the paging system (10). The paging terminal (32) retrieves the large data messages from a temporary message memory (42) to deliver to the pager/radio telephone (40).
