Intelligent Paging-Channel Scanning Based on Location Relative to Zone of Last Registration
First Claim
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, and wherein the zone of last registration is a paging zone in the radio access network;
(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.

Abstract
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.

13. A method comprising:
-
a mobile station determining a battery-power level of the mobile station, wherein the mobile station has most-recently registered with a radio access network in a zone of last registration, and wherein the zone of last registration is a paging zone in the radio access network; the mobile station determining whether the determined battery-power level is below a threshold level; if the determined battery-power level is above the threshold level, then the mobile station selecting a first scanning process; if the determined battery-power level is below the threshold level, then the mobile station selecting a second scanning process, wherein the second scanning process varies a period between scans of a paging channel based at least in part on a location of the mobile station in relation to the zone of last registration; and scanning the paging channel according to the selected scanning process. - View Dependent Claims (14)

15. A mobile-station system comprising:
-
a non-transitory tangible computer-readable medium; and program instructions stored on the non-transitory tangible computer-readable medium and executable by at least one processor to; (a) determine 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, and wherein the zone of last registration is a paging zone in the radio access network; (b) use the location of the mobile station in relation to the zone of last registration as a basis to determine a scan period to wait between scans of a paging channel for a page from the radio access network; and (c) cause the mobile station to periodically scan the paging channel according to the determined scan period. - View Dependent Claims (16, 17, 18, 19, 20)
