Abstract: A method and system for controlling connectivity in a wireless communication system that includes a first cell and a second cell, when the first cell and the second cell are both candidates to serve a given user equipment device (UE). An example method includes determining a first Radio-Resource-Control (RRC)-connection-establishment failure rate of the first cell, where the first RRC-connection-establishment failure rate of the first cell is based on one or more instances of RRC-connection-establishment failure experienced in the first cell. And the method includes using at least the determined first RRC-connection-establishment failure rate of the first cell as a basis to control whether the given UE will be connected with the first cell or rather with the second cell. Further, in this method, the one or more instances of RRC-connection-establishment failure experienced in the first cell encompass RRC-connection-establishment failure experienced by one or more UEs other than the given UE.

Abstract: A method and system for proactively reconfiguring communication to a user equipment device (UE) in anticipation the UE experiencing a coverage-throughput reduction when the UE is receiving streaming media. An example method includes (i) predicting, when the UE is receiving streaming media, that the UE is going to experience the coverage-throughput reduction and (ii) based at least in part on the predicting, proactively increasing a quality-of-service (QoS) level of a bearer through which the UE is receiving the streaming media, the proactively increasing occurring before the UE experiences the coverage-throughput reduction so that the QoS level is increased by when the UE experiences the coverage-throughput reduction.

Abstract: In a system where a first node provides a first area of TDD coverage on a first TDD carrier using a first TDD configuration and an adjacent second node provides a second area of TDD coverage on a second TDD carrier using a different second TDD configuration, the first node could additionally provide an area of FDD coverage on a first FDD carrier, including causing the area of FDD coverage to sit at least partially between the first and second areas of TDD coverage and therefore to define a spatial buffer between the first and second areas of TDD coverage. For instance, the first access node could restrict its service on the first TDD carrier to be for user equipment devices (UEs) that are relatively close to the first access node and could restrict its service on the first FDD carrier to be for UEs that are relatively far away from the first access node.

Abstract: A method and system for controlling dual-connectivity service in a system where a first access node provides service on a first air interface and a second access node provides service on a second air interface, and where (i) in a single-connection-uplink mode for the dual-connectivity service, uplink user-plane communication is carried on just the second air interface and (ii) in a split-uplink mode for the dual-connectivity service, uplink user-plane communication is split between the first air interface and the second air interface. An example method includes determining an uplink Multi-User Multiple-Input-Multiple-Output (MU-MIMO) grouping efficiency of the second air interface and, based on the determined uplink MU-MIMO grouping efficiency of the second air interface, controlling whether to provide the dual-connectivity service in the single-connection-uplink mode or rather in the split-uplink mode.

Abstract: A method and system for controlling air-interface resource utilization in a wireless communication system in which an access node provides service on a carrier defining air-interface resources. An example method includes monitoring a rate of voice muting on the carrier, detecting when the monitored rate of voice muting on the carrier is at least predefined threshold high, and responsive to detecting that the monitored rate of voice muting on the carrier is at least predefined threshold high, starting to apply a maximum limit on how many user equipment devices (UEs) the access node will concurrently serve with a resource-intensive service on the carrier.

Abstract: A method and system for dynamically controlling connectivity of a user equipment device (UE) in a wireless communication system. An example method includes (i) while the UE has dual connectivity with a first access node and a second access node, determining that power headroom of the UE on an air-interface connection between the UE and the second access node is threshold low, and (ii) responsive to at least the determining, transitioning the UE from having the dual connectivity with the first access node and the second access node to instead having standalone connectivity with the second access node. Transitioning the UE to having standalone connectivity with the second access node as to which the UE had threshold low power headroom may help to improve quality of communication between the UE and the second access node.

Abstract: A method and system for controlling data split of a dual-connected user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes (i) comparing a level of spectral efficiency of the first air-interface connection with a level of spectral efficiency of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.

Abstract: A method and system for controlling application of TTI bundling on a carrier on which an access node provides service, the carrier defining air-interface resources. An example method includes detecting that at least a predefined threshold number of devices of a predefined class (e.g., IoT devices) are connected with the access node on the carrier. Further, the example method includes, responsive to the detecting that at least the predefined threshold number of devices of the predefined class are connected with the access node on the carrier, proactively reserving a portion of the air-interface resources for use to serve communications between the access node and the devices of the predefined class and, in view of the proactive reserving of the portion of the air-interface resources, imposing a reduction in the application of the TTI bundling by the access node on the carrier.
