Abstract: A method and system to control UE handover is disclosed herein. A source base station serving a UE receives from the UE a measurement report that specifies a signal strength of a neighboring target base station. The source base station sets a value of a handover threshold parameter, with the set value being based at least in part on whether the target base station is a relay base station or a non-relay base station. Further, the source base station may compare the specified signal strength of the target base station to the set value of the handover threshold parameter and determine that a handover condition is satisfied. Responsive to making such a determination, the source base station may invoke handover of the UE from the source base station to the target base station.

Abstract: A method and system are disclosed for a base station to manage air interface communications with a user equipment device (UE) served by the base station. The base station will determine whether the served UE is a relay-UE that provides wireless backhaul connectivity for a relay base station and whether the relay base station serves at least a threshold extent of delay-sensitive communication traffic. Based on a determination that the served UE is a relay-UE and that the relay base station serves at least the threshold extent of delay-sensitive communication traffic, the base station will responsively cause the relay-UE to be served by the base station on a particular carrier frequency, in an effort to reduce a total delay resulting from the wireless relay arrangement.

Abstract: A method and system for controlling application of split-uplink mode in a wireless communication system including an access node. In an example implementation, a method includes determining a first count defining how many user equipment devices (UEs) are connected with the access node and do not support a split-uplink-mode operation in which uplink user-plane data flow is split between air-interface transmission to the access node and air-interface transmission to another access node. Further, the method includes determining a second count defining how many UEs are connected with the access node as part of dual connectivity and support the split-uplink-mode operation. And the method includes, based on the first count and the second count, controlling whether the access node will allow the split-uplink-mode operation, such as whether the access node will allow new activation of the split-uplink-mode operation.

Abstract: A method and system to control carrier aggregation in a wireless communication system including a first access node and a second access node, where the first access node has a first respective backhaul connection, where the second access node has a second respective backhaul connection, where the first access node supports serving user equipment devices (UEs) with standalone connectivity, and where the first and second access nodes cooperatively support serving UEs with dual connectivity. A method includes detecting that the second respective backhaul connection of the second access node is threshold heavily loaded. And the method includes, based at least in part on the detecting that the second respective backhaul connection of the second access node is threshold heavily loaded, causing the first access node to suppress an extent of carrier-aggregation service that the first access node will provide to any standalone-connected UEs, to help free up capacity for dual-connectivity service.

Abstract: A method and system for controlling connectivity of a user equipment device (UE). When a UE is served with dual connectivity by a first access node over a first connection in accordance with a first radio access technology (RAT) and a second access node over a second connection in accordance with a second RAT, initiation of a voice call for the UE will be detected. And in response to at least detecting the initiation of the voice call for the UE, the first access node will invoke transition of the UE from being served with the dual connectivity over the first connection and the second connection to instead being served with standalone connectivity over the first connection.

Abstract: A mechanism for controlling a measurement threshold used for triggering handover of a user equipment device (UE) when the UE is connected with a first access node, the first access node operating on a first frequency band and a second frequency band, and a second access operating on the second frequency band. A determination is made as to whether the UE supports inter-band dual-connectivity service with the UE being connected with the first access node on the first band and with the second access node on the second band. And responsive to the determination being that the UE does not support the inter-band dual-connectivity service, the measurement threshold is adjusted from a default level to an adjusted level to help facilitate handover of the UE from being connected with the first access node on the first band to being connected with the first access node instead on the second band.

Abstract: Disclosed are methods and systems for setting a timeout period. In particular, a BS may have data storage defining a buffer. Also, the BS may be configured to (i) provide an air interface through which the BS serves UEs, (ii) buffer data packets destined to individual UEs, and (iii) apply a buffer timeout process according to which the BS drops a data packet from the buffer in response to that data packet being in the buffer for a timeout period. As such, the BS may make a determination that a served UE is a relay-UE that provides wireless backhaul connectivity for a relay-BS, and may set the timeout period based on the determination. When the BS then applies the buffer timeout process, the BS drops a data packet from the buffer in response to that data packet being in the buffer for the timeout period set based on the determination.

Abstract: Disclosed are methods and systems for a user equipment device (UE) to avoid being served by a base station that experiences a threshold high extent of change of the base station's coverage identifier. In particular, the UE may detect a threshold high extent of change of a coverage identifier of a first base station, and may responsively configure itself to avoid being served by the first base station. In this way, if the UE is being served by the first base station, then the configuring may cause the UE to trigger a handover from being served by the first base station to being served by a second base station. Whereas, if the UE is not currently being served by the first base station, then the configuring effectively blacklists the first base station, such that the UE avoids attaching to and/or handing over to the first base station in the future.

Abstract: Disclosed are methods and systems to help conserve battery life of a user equipment device (UE). In particular, the UE may make a determination that a remaining battery life is threshold low. In response to making the determination, the UE may engage in a scanning-limiting process that involves (i) the UE identifying on the list each carrier frequency higher than the serving carrier frequency and (ii) based on the identifying, the UE excluding each identified higher carrier frequency from the list, so that, in response to detecting a trigger to scan carrier frequencies in search of target coverage for possible handover, the UE scans each carrier frequency on the list that is lower than the serving carrier frequency but forgoes scanning each identified higher carrier frequency. Further, once the UE detects the trigger, the UE may responsively scan carrier frequencies in accordance with the scanning-limiting process.
