Abstract: A mechanism for controlling configuration of dual connectivity for a UE that has a first connection with a first access node. The first access node could make a determination whether a level of load of a second access node with which the UE is not currently connected is threshold high. And if the determination is that the determined level of load of the second access node is not at least threshold high, then the first access node could proceed with application of a process for adding the second connection, without applying a timer for delaying application of the process. Whereas, if the determination is that the determined level of load of the second access node is at least predefined threshold high, then the first access node could apply the timer for delaying application of the process and, upon expiration of the timer, could proceed with application of the process.

Abstract: A method and system for controlling carrier load in a wireless communication system that supports multiple user equipment devices (UEs) each being primarily connected with a first access node on a first carrier and each having a respective secondary connection for dual-connectivity service. An example method includes (i) monitoring a distribution of the respective secondary connections of the UEs among being on a second carrier and being on a third carrier, the third carrier having wider bandwidth than the second carrier, (ii) based on the monitoring, determining that at least a predefined threshold portion of the UEs have their secondary connections on the third carrier rather than on the second carrier, and (iii) based at least on the determining, taking action to control load on the first carrier, such as limiting a maximum number of UEs allowed to be concurrently connected with the first access node on the first carrier.

Abstract: A method and system for controlling application of split-uplink mode for 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 the 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 detecting at least a predefined threshold high level of uplink voice muting on the first air interface and responsively restricting application of the split-uplink mode for the dual-connectivity service.

Abstract: A method and system for controlling configuration of dual connectivity of a UE in a system where the UE is served by a first access node over a first air-interface connection and in which configuring the dual connectivity includes adding for the UE a second air-interface connection with a second access node to facilitate concurrent service of the UE by the first access node over the first connection and the second access node over the second connection. An example method includes determining whether both (i) the second access node is threshold highly loaded and (ii) the UE is likely to engage in a threshold high extent of data communication when served by the second access node. And the example method includes, responsive to the determination being affirmative, forgoing from adding for the UE the second air-interface connection between the UE and the second access node.

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 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.

Abstract: A method and system for controlling connectivity of a user equipment device (UE). When the UE is connected with an access node in a cell provided by the access node, the access node determines that uplink noise in the cell is threshold high. And responsive to at least determining that uplink noise in the cell is at least threshold high, the access node applies a battery-level-based UE-offloading process to offload the UE from the cell. For instance, the access node could cause the UE to hand over or otherwise transition from being connected in the cell to instead being connected in another cell.

Abstract: Disclosed are structures and processes to help enable a wireless communication device (WCD) to support operation in a dual-connectivity scenario, such as where the WCD operates concurrently with 4G and 5G wireless connections over frequency channels in a common frequency band. Downlink low-noise-amplification could be controlled with a split dual-stage arrangement and control communication between modems in the WCD. And uplink maximum-power reduction could be controlled based on an evaluation of the frequency channels used by the respective connections, given knowledge of frequency resources allocated for one of those connections, and with a presumed worst-case-scenario frequency-resource allocation on the other connection.

Abstract: A method and system for controlling uplink transmit power of a UE when the UE is served concurrently on at least two air interfaces including a first air interface and a second air interface. An example method includes, iteratively for each successive given time interval of a continuum of equal-duration time intervals, (i) determining an actual average transmit power of the UE on the first air interface over the given time interval, (ii) using the determined actual average transmit power of the UE on the first air interface over the given time interval as a basis to set a maximum average transmit power of the UE for transmission on the second air interface in a respective subsequent time interval, and (iii) applying the set maximum average transmit power as a limitation on uplink transmit power of the UE for the transmission on the second air interface in the respective subsequent time interval.

Abstract: A method and system for controlling connectivity of a user equipment device (UE). When a UE is served with dual connectivity by a first access node over a first connection in accordance with a first radio access technology (RAT) and a second access node over a second connection in accordance with a second RAT, initiation of a voice call for the UE will be detected. And in response to at least detecting the initiation of the voice call for the UE, the first access node will invoke transition of the UE from being served with the dual connectivity over the first connection and the second connection to instead being served with standalone connectivity over the first connection.
