Abstract: A radio access network (RAN) may be configured to identify a set of wireless coverage areas in which to transmit inter-frequency search directives. Identifying the set of coverage areas may involve determining which of the coverage areas defined by the RAN have threshold weaker coverage on one carrier frequency than on another carrier frequency of that coverage area. For each coverage area of the set, the RAN may identify one or more WCDs operating in the coverage area that are operating on the coverage area's carrier frequency that has the weaker coverage. Based on the identifying of the WCDs, the RAN may send to each identified WCD an inter-frequency search directive to cause the WCD to scan for and report to the RAN a measurement of coverage on one or more carrier frequencies other than the carrier frequency on which the WCD is currently operating.

Abstract: A request to establish a call involving a wireless communication device (WCD) served by a radio access network (RAN) may be received. The WCD may receive signals from the RAN via a plurality of wireless coverage areas at respective signal strengths. The plurality of wireless coverage areas may be defined by the RAN. A media codec to use for the call and a target bitrate for the media codec to use during the call may be determined. Based on the target bitrate, a set of n wireless coverage areas through which the WCD and the RAN communicate during the call may be selected. The value of n may be between one and a predetermined maximum number. The set of n wireless coverage areas may be selected from the plurality of wireless coverage areas.

Abstract: Embodiments may involve the adjustment of the way in which coverage areas are included in the active set of a wireless communication device (WCD), based on the codec that is currently associated with the WCD. An illustrative method involves a radio access network (RAN): (a) determining a codec that is associated with a WCD; (b) using the associated codec as a basis for determining a value for at least one active-set parameter for the WCD; and (c) sending a message to the WCD, wherein the message indicates the determined value for the at least one active-set parameter.

Abstract: A method and corresponding system for management of neighbor scanning in a cellular wireless communication system is disclosed. A radio access network (RAN) sends, and a mobile device receives, a neighbor list update message containing a plurality of different neighbor lists each listing available neighboring coverage areas communicating on respective communication channels. While the mobile device is engaged in a call, the mobile device selects one of the neighbor lists based on a service type of the engaged call. The mobile device scans the neighbors listed in the selected neighbor list for signal strengths sufficient to trigger a hand off. The mobile device sends a report indicating measured signal strengths of signals from the neighbors to the RAN, which then instructs the mobile device to hand off the engaged call.

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.
