    Abstract: A method and system for controlling wireless service of a user equipment device (UE) by an access node. The access node serves the UE with uplink carrier-aggregation over a connection encompassing multiple uplink channels including a primary uplink channel (uplink PCell) and a secondary uplink channel (uplink SCell). Further, the access node dynamically sets a channel-quality threshold applicable to control when to deconfigure the uplink SCell from service of the UE, with the dynamically setting of the channel-quality threshold including setting the channel-quality threshold to a value selected based on one or more operational circumstances of the UE, such as whether the UE is engaged in uplink heavy or rather uplink light communication. And the access node applies the dynamically set channel-quality threshold to control when to deconfigure the uplink SCell from service of the UE.

    Abstract: A method and system for controlling air-interface connectivity of a user equipment device (UE). A computing system detects, when the UE has dual connectivity including a first air-interface connection with a first access node and a second air-interface connection with a second access node, and when the first air-interface connection is defined on a first carrier, that the UE is moving toward a geographic area where UEs that were served by the first access node on the first carrier as part of dual connectivity lost their dual connectivity due to their having insufficient aggregate dual-connectivity throughput. And based at least on the detecting, the computing system reconfigures the first air-interface connection of the UE's dual connectivity to be defined on a lower-frequency second carrier, to help avoid having the UE lose its dual connectivity.

    Abstract: When a UE is served by a first radio access network (RAN) and is engaged in a voice call such as a VoIP call, a determination will be made that the UE is at an edge of coverage (e.g., threshold poor coverage) of the first RAN and that there is no other adjacent coverage of the first RAN that could support the voice call. In response, signaling will cause a second RAN to page the UE via the first RAN so as to cause the UE to transition from being served by the first RAN to being served by the second RAN. More generally, when a UE has poor coverage of its serving RAN, another RAN will pull the UE to the second RAN by paging the UE to trigger transition of the UE from to the second RAN.

    Abstract: Methods and systems for controlling service by a base station when the base station is serving both a first UE without carrier aggregation and a plurality of second UEs with carrier aggregation. As a basis for invoking carrier aggregation service for the first UE, the base station selects one of the second UEs to transition from being served by the base station with carrier aggregation to being served by the base station without carrier aggregation. The base station makes such a selection based at least in part on a modulation and coding scheme that the base station uses to serve the selected one of the second UEs. The base station transitions from serving the selected second UE with carrier aggregation to serving the selected second UE without carrier aggregation. And the base station transitions from serving the first UE without carrier aggregation to serving the first UE with carrier aggregation.
