Abstract
Abstract A system and method including a flexible paging protocol which adjusts the allocation of resources for paging in response to the amount of actual paging traffic, by increasing resources for paging when paging traffic is heavy and decreasing them when paging traffic is light. A base station transmits a paging packet message over a paging broadcast channel containing a set of paging messages and a next page pointer. The next page pointer identifies when the next set of paging packet message will be transmitted. A user station monitoring the paging channel receives the next page pointer, and, if not being paged, goes to sleep until the next paging packet message is due. When paging traffic is light, paging messages are sent infrequently, freeing up base station resources and allowing the user station to remain asleep longer. When paging traffic is heavy, paging messages are sent more frequently, ensuring rapid response to the pages and reducing the probability of a missed call. The protocol is particularly well suited for use in TDMA environments. The next page pointer may be used in conjunction with a system which also employs a next slot pointer for increasing the speed of control traffic transactions. In a wireless packet-oriented communication system, the base station receives data packets over a backhaul connection, transmits a paging message to the mobile end system, divides the data packet into a sequence of message frames, and transmits the message frames to the mobile end system in assigned time slots.
