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 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.

Abstract: A method and system to help manage resources in a fallback scenario is disclosed. A first network may be configured to serve user equipment devices (UEs) according to a first protocol and a second network may be configured to serve UEs according to a second protocol. The method may involve the first network serving a UE, where serving the UE includes allocating at least one resource to the UE. The method may also involve, after the UE has transitioned from being served by the first network to being served by the second network for a circuit-switched-fallback call, (i) if the UE completes call setup, the first network releasing the resources, but (ii) if the UE does not complete call setup, the first network using the allocated resources to serve the UE after the UE transitions back to being served by the first network.

Abstract: In one aspect, an exemplary method involves a WCD: (i) determining a likelihood of roaming, wherein the likelihood of roaming indicates a likelihood that the WCD will be handed off from a preferred coverage area to a non-preferred coverage area; and (ii) using the likelihood of roaming as a basis for managing an active set of the WCD. In particular, the WCD may manage its active set by setting at least one active-set parameter affecting the number of active sectors in an active set of the WCD, and then maintaining its active set according to the setting of the at least one active-set parameter. According to an exemplary embodiment, a WCD will make an effort to increase the number of sectors in its active set when the likelihood of roaming is greater, and vice versa.

Abstract: A method and system for pre-configuring a UE with timing advance for use in communication with a handover target. When a UE is being served by a handover source, the handover source transmits to a handover target a measurement request that specifies an uplink reference signal that the UE will provide, and the handover target evaluates that uplink reference signal to determine a timing advance for the UE and reports the timing advance in a response to the handover source. As the handover source then directs the UE to hand over to the handover target, the handover source provides the UE with an indication of the timing advance provided by the handover target. The UE may then transition to be served by the handover target and to make use of the indicated timing advance.

Abstract: A method and system for dynamically selecting call setup procedure based on channel quality. While a wireless communication device (WCD) is being served by a first radio access network (RAN), a network node receives an indication of a communication quality of the at least one channel used by the first RAN to serve the given WCD. Then, the network node selects a call setup procedure for establishing a call to be served by a second RAN based on the received indication of the communication quality of the at least one channel, where the selected call setup procedure comprises the given WCD transitioning to be served with the call by the second RAN. Next, the network node signals to invoke setup of the call using the selected call setup procedure.

Abstract: A method and system to help avoid a failed eCSFB call setup in the presence of handover. While a WCD is being served by a base station of a first network, the base station may detect both a fallback trigger and a handover trigger. The fallback trigger may be a trigger to initiate a fallback setup procedure, where the fallback setup procedure involves execution of a sequence of steps including a particular step. The handover trigger may be a trigger to initiate a handover procedure. The base station determines that the handover trigger was detected before execution of the particular step of the fallback setup procedure. Responsive to determining that the handover trigger was detected before execution of the particular step, the base station (a) foregoes the fallback setup procedure and (b) transmits to the WCD a message directing the WCD to establish communication with the second network.

Abstract: Disclosed is a method and system of managing an allocation of resources in a wireless communication system. According to the disclosure, a base station may receive or otherwise determine an indication of radio frequency (RF) conditions being perceived by a given user equipment device (UE). Based on that indication, the base station may make a decision of whether to use a first resource limitation or a second resource limitation for data transmissions to the given UE, where the second resource limitation generally allows for a lesser extent of resources to be allocated than the first resource limitation in weaker RF conditions. For instance, the base station may decide to use a bit-rate limitation for threshold strong RF conditions and a resource-block limitation for threshold weak RF conditions. Thereafter, the base station may allocate resources for a data transmission to the given UE in accordance with the decision.

Abstract: It may be determined that a HARQ transmission schedule from a RAN to a WCD includes HARQ acknowledgment bundling. An indication of signal quality as measured by the WCD may be received by the RAN. The indicated signal quality may be associated with a first transmission rate. The RAN may determine a first set of one or more data slots of the HARQ transmission schedule for which the WCD bundles HARQ acknowledgments. In response to this determination, one or more HARQ subpackets may be transmitted to the WCD in the first set of one or more data slots. The one or more HARQ subpackets may be transmitted at a second transmission rate that is less than the first transmission rate.
