Abstract

In an improved system and method for paging cellular mobile stations, an incoming call signal intended for a paged cellular mobile station is received into a base station. Next, a page frame is assembled having a header that identifies the page frame as a hard page frame containing a prescribed number of mobile station identification numbers. The page frame contains an associated mobile station identification number associated with the paged cellular mobile station, and a dummy mobile station identification number. The page frame is transmitted to, and is disassembled within the paged cellular mobile station. The associated mobile station identification number is recognized within, the paged cellular mobile station, and, within each of a plurality of cellular mobile stations, the dummy mobile station identification number is ignored.
