Abstract: A method and system to help control connectivity of a UE served with dual connectivity by a master node and a plurality of secondary nodes. An intermediary that is disposed between a core-network gateway system and the secondary nodes tracks data flow between the gateway system and the secondary nodes and provides the master node with a data-flow report, which the master node could use as a basis to trigger release of the UE's RRC connection, and/or to control addition or removal of one or more secondary nodes for the UE's dual-connectivity service.

Abstract: In an arrangement where an access node (e.g., a Node-B) is used in dual-connectivity service of UEs that are served by other access nodes, resources of the access node could be dynamically allocated to the UEs based at least on respective priorities designated for the other access nodes. For instance, each other access node could be prioritized based on its type, such as whether it is a macro access node, a small-cell access node, an indoor access node, an access node for a special event, or a access node for dedicated service, among other possibilities, and allocation of resources of the jointly-used access node could be defined based on these priorities, giving higher resource-allocation priority to UEs that are served by a higher priority other access node and giving lower resource-allocation priority to UEs that are served by a lower priority other access node.

Abstract: A wireless air interface may be defined for communication with a wireless communication device (WCD). The wireless air interface may include paired low-frequency channels and paired high-frequency channels, where the paired low-frequency channels include a low-frequency downlink channel and a low-frequency uplink channel, and where the paired high-frequency channels include a high-frequency downlink channel and a high-frequency uplink channel. It may be determined that, on at least one of the downlink or uplink channels, the WCD is experiencing a quality of wireless coverage below a threshold wireless coverage value. Possibly in response to the WCD experiencing the quality of wireless coverage below the threshold wireless coverage value, the downlink and uplink channels may be reconfigured so that the paired low-frequency channels include two low-frequency uplink channels and the paired high-frequency channels include two high-frequency downlink channels.
