Abstract:
1. A method of providing a presence service, comprising: determining a paging channel load in a zone of a wireless telecommunications network; sending a plurality of outgoing presence updates to a mobile station located in the zone, wherein the outgoing presence updates are sent over the wireless telecommunications network on a channel different from the paging channel; throttling the outgoing presence updates while the paging channel load exceeds a threshold load, wherein the throttling is minimum-delay throttling, and wherein throttling the outgoing presence updates comprises scheduling presence updates so that a minimum delay passes between presence updates to the mobile station, wherein the minimum delay is based at least in part on the paging channel load; selecting one of a plurality of levels of throttling for the mobile station, wherein the throttling of the outgoing presence updates is performed at the selected level; and determining an amount of time that has elapsed since the mobile station began a presence session, wherein the level of throttling is determined at least in part by the amount of time that has elapsed since the mobile station began the presence session.
