Abstract
A paging system which provides both individual and information services includes a transmitter which transmits page call address and data periodically in batches to subscribing paging receivers. Each batch comprising a synchronization code followed by a predetermined plurality of sequential frames. Each paging receiver searches for both its individual service address and a first information service address in its corresponding assigned frame of each batch of a transmission period, and in response to reception of the first information service address, searches for a second information service address in a designated common frame of each batch of a transmission period. Individual and information service data messages are obtained from frames immediately subsequent the frame in which the respective individual and second information service addresses are found.
