Abstract: Disclosed is a method and corresponding apparatus for management of access probe transmission from a wireless communication device (WCD) to a radio access network (RAN). The WCD determines that a particular coverage area is not the strongest coverage area detected by the WCD, and the WCD responsively transmits an access probe to the RAN in that particular coverage area. For instance, the WCD may define a sequence of access probe transmissions including at least one transmission to just a coverage area that the WCD deems to not be the strongest and further including at least one transmission to just a coverage area that the WCD deems to be the strongest.

Abstract: Described are various approaches for considering inter-base-station link congestion levels in connection with handoff of a mobile station when the source base station (or another entity) is able to select a target base station for handoff from among a plurality of base stations. In one aspect, the plurality of base stations are each communicatively linked via a respective inter-base-station link with the source base station serving the mobile station. The source base station (or another entity) selects the target base station from among the plurality of base stations based at least in part on a congestion level of each base station's respective inter-base-station link. The source base station then hands off the mobile station to the target base station.

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 vertical handoff of a mobile station from a first-protocol RAN to a second-protocol RAN. The method and system provide a make-before-break vertical handoff, by having the first-protocol RAN (i) acquire, on behalf of the mobile station, a traffic channel assignment defining one or more traffic channel parameters for air interface communication in the second-protocol RAN, and (ii) pass to the mobile station, via the first air interface protocol, the one or more traffic channel parameters so that the mobile station can then readily switch over to communication under the second-protocol RAN. Optimally, the acquisition and passing of the one or more second-protocol traffic channel parameters may occur without the mobile station having requested the handoff, without the mobile station having asked for the traffic channel assignment, and without the mobile station having yet begun communication with the second-protocol RAN.

Abstract: An exemplary method involves a user equipment (UE) receiving a communication-origination request to initiate a communication with a given counterpart. In response, the UE: (a) uses historical communication data for one or more previous communications as a basis for evaluating whether the UE is likely to be assigned a particular codec, from a plurality of possible codecs, for communication with the given counterpart; (b) based on results of the evaluation, determines a respective setting for each of one or more access parameters affecting a likelihood of successfully establishing the communication with the given counterpart; and (c) performs the communication-origination process according to the determined settings for the one or more access parameters, to initiate the requested communication with the given counterpart.

Abstract: One or more packets to be transmitted to or from a user equipment (UE) device are determined to have a particular packet length, e.g., based on a vocoder to be used for a voice over Long Term Evolution (VoLTE) call. An initial modulation and coding scheme (MCS) is selected for transmission of the packets based on channel conditions. The initial MCS is replaced by an alternative MCS having a lower efficiency than the initial MCS in response to a determination that the alternative MCS would require the same number of resource blocks to transmit a packet having the particular packet length as the initial MCS. One or more resource blocks are allocated for transmission of the one or more packets having the particular packet length using the alternative MCS. Indications of the allocated one or more resource blocks and the alternative MCS are transmitted to the UE.

Abstract: Disclosed are methods and systems for managing allocation of air interface resources to a relay user equipment device (relay-UE) that provides wireless backhaul connectivity for a relay base station (relay-BS). In particular, a base station may serve the relay-UE and may make a determination that the relay-UE is positioned within an indoor environment rather than within an outdoor environment. While serving the relay-UE, the base station may manage allocation of air interface resources to the relay-UE and may do so based at least on the determination that the relay-UE is positioned within an indoor environment rather than within an outdoor environment.

Abstract: A method and system for scanning for target coverage in order of signal strength threshold. In a wireless communication system that defines a plurality of wireless coverage areas, a user equipment device (UE) may seek to select one of the coverage areas in which to operate. Each coverage area may have a respective downlink receive signal strength threshold (DSST) defining a minimum downlink receive signal strength for triggering UE selection of the coverage area. While operating in the wireless communication system, the UE may be arranged to rank-order the coverage areas in order of their respective DSSTs so as to define a sequence of the coverage areas. The UE may be arranged to then scan the coverage areas in order of the defined sequence, in search of a coverage area to select to operate in.
