Patent ID: 8073470

Claim:
A method of paging for wireless networks comprising: synchronizing a window clock of a wireless terminal to a server window clock, wherein the server window clock is separate from and is only synchronized periodically with the window clock of the wireless terminal; determining whether the wireless terminal is in a traffic mode or a standby mode; in the event that the wireless terminal is in standby mode, determining whether the window clock of the wireless terminal indicates that the wireless terminal is in a paging window or in a dormant window using a set of instructions, wherein the paging window has a duration at least as long as a duration from a start of a first paging slot to an end of a second paging slot between the wireless terminal and the server such that the paging window overlaps at least one paging slot between the wireless terminal and a base station, and wherein the dormant window has a duration greater than at least twice a period between the first paging slot and the second paging slot, wherein the period between the first paging slot and the second paging slot is based at least in part on a paging clock of the base station or a paging clock of the wireless terminal; and in the event that the wireless terminal is in the dormant window, maintaining sleep of the circuitry of the wireless terminal and not waking up circuitry for any paging slots between the wireless terminal and the server; in the event that the wireless terminal is in the paging window: waking up circuitry to receive and to respond to the page; determining a paging interval and a paging period, wherein the paging interval is based at least in part on a function of the wireless terminal identifier, a time, and a first paging period to distribute a paging load of the wireless network; listening for the page during the paging period occurring at a time based at least in part on the paging interval; receiving the page from the server at the wireless terminal if and only if a message is sent from the server to the wireless terminal; and causing the circuitry of the wireless terminal to sleep.
