摘要： A mechanism for controlling operation of a first access node that supports operation according to a first radio access technology (RAT) but does not support dual-connectivity operation according to the first RAT and a second RAT. A system detects a high extent of occurrences of dual-connectivity-capable user equipment devices (UEs) being connected with the first access node when the dual-connectivity-capable UEs could instead connect with a second access node that supports the dual-connectivity operation. And in response, the first access node blocks dual-connectivity-capable UEs from being connected with the first access node while allowing UEs that are not dual-connectivity capable to be connected with the first access node.

摘要： A method and system for controlling application of MU-MIMO. The disclosure provides for considering a device's block error rate (BLER) as a basis to decide whether to provide the device with MU-MIMO service. For instance, a base station could determine which of the base station's served devices each have threshold low BLER. And on at least that basis, the base station could select each such device to receive MU-MIMO service. Or faced with a choice between devices to receive MU-MIMO service, the base station could compare the devices' levels of BLER and could select the devices that have lower BLER to receive MU-MIMO service.

摘要： Disclosed herein is a system and method for tearing down a radio link based on keepalive message activity. An example method involves a radio access network (RAN) establishing a radio link with a wireless communication device (WCD); the RAN detecting that the RAN received periodic keepalive messages from the WCD via the radio link; and responsive to the RAN detecting that the RAN received periodic keepalive messages via the radio link, the RAN tearing down the radio link.

摘要： Disclosed are methods and systems for selecting a carrier on which to serve a user equipment device (UE). In particular, a base station may determine that a speed of movement of the UE is threshold high. In response to determining that the speed of movement of the UE is threshold high, the base station may select a carrier based on a group delay variation (GDV) of the selected carrier. For example, the base station may respond to the determining by selecting a carrier having a threshold low GDV. In another example, the base station may respond to the determining by selecting the carrier having the lowest GDV among two or more candidate carriers being considered as part of the selection process. As such, once a carrier is selected, the base station may then serve the UE on the selected carrier.

摘要： A base station could establish maximum transmit power that the WCD should apply per carrier when serving the WCD on multiple carriers, with the base station considering the WCD's total power headroom and a delta of the WCD's uplink receive power per carrier. For instance, the base station could determine the WCD's total power headroom and could determine a receive power delta per carrier, the base station could effectively re-distribute the WCD's total power headroom among the carriers as adjustments to the maximum transmit power per carrier in accordance with a relative comparison of the receive power deltas on the carriers, the base station could further shift the adjustments to keep the sum of the WCD's maximum transmit power of the carriers in line with the WCD's maximum total transmit power, and the base station could direct the WCD to apply the shifted adjusted maximum transmit values.

摘要： A method and system for dynamically allocating backhaul bearer service based on network loading conditions to help use backhaul-network resources more efficiently. A RAN detects an event relating to bearer service establishment for a given application. Then the RAN identifies a standard bearer service for the given application, where the standard bearer service has a first quality of service. After detecting the event, the RAN determines that a load of the backhaul communication network does not exceed a load threshold. Then, based on the determination that the load of the backhaul communication network does not exceed the load threshold, the RAN selects a bearer service for the given application, where the selected bearer service has a second quality of service that is higher than the first quality of service. Next, the RAN causes the selected bearer service to be established.

摘要： A mechanism to help control connectivity of a user equipment device (UE). When the UE is served by a master node (MN) that does not support VOP service, the MN will cause the UE to not have a secondary connection with a secondary node (SN) that would engage in control-plane signaling with the UE via the UE's master connection with the MN. For instance, in that situation, the MN could avoid setting up the secondary connection for the UE in the first place. Or if the secondary connection exists already, the MN could tear down that secondary connection. By causing the secondary connection to not exist, the mechanism may help to avoid problems with operation of the secondary connection as a result of the UE tuning away to facilitate voice service.

摘要： A base station that is configured to provide first-RAT service on multiple carriers will reserve at least one of the carriers for use in providing UEs with dual-connectivity service on the first RAT and a second RAT, and the base station will reserve at least one other of the carriers for use in providing UEs with standalone first-RAT service. For instance, a 4G base station that is configured to provide 4G service on multiple 4G carriers could reserve at least one of those 4G carriers for use in providing UEs with EN-DC service (where each UE would be served concurrently on a 5G carrier as well) and could reserve another one of those 4G carriers for use in providing UEs with standalone 4G service.

摘要： 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 what type of UE the UE is, such as whether the UE is a relay-UE or rather an end-user UE for instance. Based on the determined type, the first access node could then control whether to apply blind addition or rather threshold-based addition in adding for the UE a second connection with a second access node. For instance, if the UE is an end-user UE rather than a relay-UE, then the first access node could apply blind addition rather than threshold-based addition, and if the UE is a relay-UE rather than an end-user UE, then the first access node could apply threshold-based addition rather than blind addition.

摘要： A method and system for controlling application of MU-MIMO. The disclosure provides for considering a device's mobility as a basis to decide whether to provide the device with MU-MIMO service. For instance, a base station could determine which of the base station's served devices are each stationary or moving less than a threshold extent. And on at least that basis, the base station could select each such device to receive MU-MIMO service. Or faced with a choice between devices to receive MU-MIMO service, the base station could compare the devices' speed of movement and could select the devices that have lower speed of movement to receive MU-MIMO service.
