Intelligent paging-channel scanning based on location relative to zone of last registration

摘要

Exemplary methods and systems are disclosed herein that may, among other benefits, help a mobile station to conserve power by intelligently determining how often to scan for incoming pages. An exemplary method may be carried out by a mobile station that has most-recently registered with a radio access network in a zone of last registration, and involves the mobile station (a) determining a location of the mobile station in relation to the zone of last registration, (b) using the location of the mobile station in relation to the zone of last registration as a basis for determining a scan period to wait between scans of the paging channel; and (c) periodically scanning the paging channel according to the determined scan period. Furthermore, an exemplary method may be carried out in order to conserve battery power when a mobile station determines that its battery power is low.

主权项

1. A method comprising:
(a) at a mobile station that is operating in a radio access network, determining a location of the mobile station in relation to a zone of last registration, wherein the mobile station last registered with the radio access network in the zone of last registration, wherein the zone of last registration is a paging zone in the radio access network, wherein determining the location of the mobile station in relation to a zone of last registration comprises:
(i) determining a current paging zone in which the mobile station is currently located, wherein the current paging zone is a paging zone in the radio access network; and(ii) determining a location of the current paging zone in relation to the zone of last registration; (b) the mobile station using the location of the mobile station in relation to the zone of last registration as a basis for determining a scan period to wait between scans of a paging channel for a page from the radio access network; and (c) the mobile station periodically scanning the paging channel according to the determined scan period.
