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 mechanism for controlling secondary-coverage scanning for configuring dual-connectivity. A computing system establishes for a primary access node a scan list of secondary cells based on the primary access node having an X2 interface for each secondary cell and having received a threshold extent of B1 measurement reporting indicating threshold strong coverage of the secondary cell for configuration of dual-connectivity. Further, the computing system establishes for each secondary cell of the scan list a respective B1 measurement threshold based on evaluation of performance history of the secondary cell such as based on extent of secondary-access-node-addition failures involving the secondary cell and/or based on communication-quality metrics such as error rate or retransmission rate. The computing system then configures the primary access node to provide a B1 measurement object conveying the scan list with measurement thresholds.

Abstract: A cell site that has multiple first-RAT carriers will monitor a capacity demand respectively of each first-RAT carrier, with capacity demand representing an extent to which adding more service capacity could be useful in view of the state of service on the 4G carrier. Further, the cell site will dynamically allocate resources of a second-RAT carrier for use in dual-connectivity service of UEs served on various ones of the first-RAT carriers, with the allocation being based on the capacity demands of the various primary-RAT carriers. For instance, if a first first-RAT carrier has a higher capacity demand than a second first-RAT carrier, then the cell site could allocate a more resources of the secondary-RAT carrier for use in dual-connectivity service of UEs served on the first first-RAT carrier than for use in dual-connectivity service of UEs served on the second first-RAT carrier.
