Abstract: Disclosed are methods and systems for selection of a handover target for a user equipment device (UE). In particular, a wireless communication system may serve the UE over an air interface connection between the UE and a source base station (BS). While the system serves the UE, the system may make a selection of a handover target for the UE. And in accordance with the disclosure, the selection may be based at least in part on the handover target not having a wireless relay backhaul connection. Once the system selects the handover target using the disclosed approach, the system may then trigger handover of the UE from being served by the source BS to being served by the selected handover target.

Abstract: Disclosed herein is a method and corresponding system for managing communication in a first network, where the first network is interconnected with a fallback network. The first network may detect, when a user equipment device (UE) served by a base station of the first network seeks to initiate a voice call, the UE will transition from being served by the first network to be served by the fallback network in order to initiate the voice call directly via the fallback network rather than initiate the voice call via the first network. In response to detecting this, and further in response to the base station not supporting signaling between the UE and the fallback network, the first network may cause the UE to not transition to be served by the fallback network and to instead stay served by the base station.

Abstract: Disclosed are methods and systems for requesting a UE to forgo handover to a congested neighbor. In particular, a wireless communication system may serve the UE over an air interface connection between the UE and the first base station. While serving the UE, the wireless communication system may receive from the UE a handover request requesting a handover of the UE from the first base station to a second base station. In response to receiving from the UE the handover request, the wireless communication system may determine that the second base station is threshold congested, and, responsive to the determining, (i) deny the handover request and (ii) send to the UE a command for the UE to withhold transmission of further requests for handover of the UE from the first base station to the second base station.

Abstract: Disclosed herein is a method and a corresponding system for managing quantity of carriers, based at least in part on consideration of a public land mobile network (PLMN) to which the user equipment device (UE) at issue subscribes. A base station serving the UE may determine the PLMN to which the UE subscribes and, based at least on the UE's PLMN, may determine a quantity of carriers on which to serve the UE, the determined quantity of carriers being at least one carrier. The base station may then configure an air interface between the base station and the UE to encompass the determined quantity of carriers, so that the base station is then set to serve the UE on the determined quantity of carriers.

Abstract: In an example method, a base station encounters a trigger to begin providing carrier aggregation service to a UE. The base station is serving the UE on a first carrier, and makes a determination that the first carrier is a carrier having an uplink transmission power restriction rather than a carrier that does not have the uplink transmission power restriction. Responsive to encountering the trigger: based at least on the determination, the base station initiates a handover of the UE from the first carrier to a second carrier that does not have the uplink transmission power restriction; and the base station providing the UE with the carrier aggregation service, using the second carrier as a primary carrier during the carrier aggregation service.

Abstract: A base station may provide wireless service on an air interface that defines different mutually exclusive groups of random access channel (RACH) instances for different uses. In one example, the air interface may define a first group of RACH instances having groupings of preambles for designating a value of a characteristic, and define a second group of RACH instances that does not have groupings of preambles. As another example, the air interface may define a first group of RACH instances that has groupings of preambles for designating a value of a first characteristic, and define a second group of RACH instances that has groupings of preambles for designating a value of a second characteristic. The base station may then differentially handle random access requests based on whether the base station receives a preamble in a RACH instance of the first group or rather the second group.

Abstract: A method and systems for allocating wireless communication resources between access link and relay link. An example method involves determining a remaining battery level of one or more user equipment devices (UEs) that are served by a relay base station. The method also involves establishing an allocation of wireless communication resources between a relay backhaul link and a relay access link based at least on the determined remaining battery level of the one or more UEs. And the method then involves, responsive to the establishing of the allocation of the wireless communication resources, configuring the relay backhaul link and the relay access link based on the established allocation of the wireless communication resources.

Abstract: A method and system is disclosed for dynamic swapping of uplink and downlink base stations. A user equipment device (UE) may engage in a communication session with a downlink from a first base station (e.g., eNodeB) and an uplink to second, different base station. If a determination is made that more favorable operating conditions for transmitting session communications to the UE are available on a downlink air interface from the second base station than on the downlink air interface from the first base station, the uplink and downlink may be swapped, such that after swapping, the UE may have a downlink from second base station and an uplink to the first base station.

Abstract: A wireless communication device (WCD) may determine that the WCD has bearer traffic queued for transmission to a radio access network (RAN). The WCD may be configured to transmit the bearer traffic and neighbor reports over a reverse-direction channel of the RAN. The neighbor reports may contain information related to wireless coverage areas. One or more characteristics of the bearer traffic may also be determined. Based on the one or more characteristics of the bearer traffic, the neighbor reports may be scheduled to be transmitted over the reverse-direction channel at a particular rate. The WCD may transmit the neighbor reports over the reverse-direction channel at the particular rate.

Abstract: Methods and systems for making decisions regarding handing off a user-equipment device from a serving base station to a neighboring base station. Base stations in a wireless communication network measure parameters regarding forward-links from the base stations and reverse-links to the base stations. Each base station transmits its measured parameters to its neighboring base station(s). Each base station can determine differences between the parameters it measures and the parameters measured by a neighboring base station. The differences indicate whether the quality of service provided by the serving base station is greater than the quality of service provided by a neighboring base station. The servicing base station transmits the differences to user-equipment devices served by that base station. The user-equipment device compares the differences pertaining to the serving base station and multiple neighboring base stations and selects a neighboring base station to which the user-equipment device is to be handed over.
