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 an aggregate frequency bandwidth of the first air-interface connection with an aggregate frequency bandwidth 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 processing by a data server. An example method includes a computing system receiving from a client entity a request for information, and, responsive to receiving from the client entity the request, the computing system (i) determining, based on the client entity from which the computing system received the request, a processing time limit for the data server to apply in processing a query for the information and (ii) generating and sending to the data server the query, including in the query an indication of the determined processing time limit. The data server could thus receive and process the query and impose the specified processing time limit on the processing of the received query.

Abstract: A base station or an associated control entity determines when base station's air interface is threshold highly loaded or is predicted to be threshold highly loaded, and the base station responsively reduces the number of transmit antennas that the base station uses. Further, the base station or associated control entity could determine when the base station's air interface is no longer actually or predicted to be threshold highly loaded, and the base station could responsively increase the number of transmit antennas that the base station uses, such as by reverting to use a default number of antennas. Reducing the number of transmit antennas that the base station uses when its air interface is threshold highly loaded may help to increase air-interface capacity by reducing resource consumption from transmission of reference signals associated with the transmit antennas.

Abstract: A method and system for controlling uplink communication from a user equipment device (UE) that 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 comparing a level of antenna pattern efficiency associated with the first air-interface connection with a level of antenna pattern efficiency associated with the second air-interface connection and, based at least on the comparing, configuring an uplink split ratio defining a distribution of uplink user-plane data flow of the UE between at least the first air-interface connection and the second air-interface connection. In an example implementation, this could involve configuring one of the air-interface connections as a primary uplink path to which the UE restricts its uplink communication unless and until a trigger occurs for transitioning the UE to operate in an split-uplink mode.

Abstract: In a wireless communication system including a first access node and a second access node, where the first and second access nodes cooperatively support providing user equipment devices (UEs) with dual-connectivity service, where data flows between the first and second access nodes, and where a proper subset of the data flowing between the first and second access nodes is user-plane data of the dual-connectivity service, a method includes (i) detecting that a total volume of the user-plane data that flows between the first and second access nodes is at least as high as a predefined threshold, and (ii) based on at least the detecting, blocking new establishment of the dual-connectivity service.

Abstract: A method and system to dynamically reassign RF spectrum from a first access node to a second access node, where the first access node provides service on a first carrier having a carrier bandwidth. An example method includes (i) selecting a frequency portion of the carrier bandwidth to reassign, the selecting being based on the frequency portion having higher determined noise than one or more other frequency portions of the carrier bandwidth, and (ii) based on the selecting, reassigning the selected frequency portion from the first access node to the second access node to be used by the second access node as at least part of a second carrier on which to provide service. Upon reassigning of the selected frequency portion, the second access node could then provide service on the reassigned portion and the first access node could continue to provide service on a remainder of the first carrier.

Abstract: A method and system for controlling connectivity of a user equipment device (UE), the UE being dual-connectivity capable. The UE detects that the UE has ping-ponged at a threshold high rate between standalone connectivity and dual connectivity. And responsive to at least detecting that the UE has ping-ponged at the threshold high rate between standalone connectivity and dual connectivity, the UE transmits, to an access node serving the UE, a report including an indication that the UE is not dual-connectivity capable, even though the UE is dual-connectivity capable. The access node could then use the indication in the report as a basis to forgo configuring of dual connectivity for the UE, which could thereby help discontinue the ping-ponging.

Abstract: Systems and methods are provided for dynamically changing a channel state information (CSI) reporting protocol by adjusting CSI reporting frequency for a wireless device communicating with an access node within a wireless network. The methods and systems identify a power headroom (PHR) value at a particular wireless device and adjust the CSI reporting frequency when the PHR satisfies a predetermined threshold. The method changes the CSI reporting frequency for the wireless device to enable more frequent CSI reporting over a primary path to the access node to facilitate reallocation of resources.

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: A method and system for responding to a processing failure of an Internet Protocol (IP) Multimedia Subsystem (IMS). An example method includes a computing system detecting the processing failure of the IMS and responsively causing one or more user equipment devices (UEs) to forgo using the IMS for voice over IP (VoIP) call placement and to instead use an alternate VoIP calling service for VoIP call placement. For instance, a given UE may be configured by default to use the IMS for VoIP call placement, but the UE may detect an IMS processing failure and may responsively instead make a next VoIP call placement attempt using an alternate VoIP calling service, such as a third party VoIP calling application running on the UE.
