    摘要： In a wireless communication system where a wireless access network includes a base station providing coverage in which to serve devices and where the wireless access network provides connectivity with an Internet Multimedia Subsystem (IMS), a method and system to help manage network resources by dynamically controlling when setup of a dedicated bearer will be invoked for a packet-based call placed by a device served by the base station. If the base station is lightly loaded, then setup of dedicated bearer could be invoked before the called party answers the call. Whereas, if the base station is heavily loaded, then setup of the dedicated bearer could be invoked if and when the called party has answered.

    摘要： Disclosed are methods and systems for configuring service of a user equipment device (UE). When the UE has dual-connectivity service, such as EN-DC service, poor quality on one of the UE's air-interface connections could result in transition of the UE to single-connectivity service. To address technological issues that may arise in this process, one of the UE's serving Node-Bs (NBs) could control teardown of an access bearer homed to the other of the UE's serving NBs. Further or alternatively, a control-plane signaling path that is homed to one of the UE's serving NBs could be replaced with a control-plane signaling path instead homed to the other of the UE's serving NBs. In addition, in appropriate circumstances, when such reconfiguration occurs, service of the UE could be switched from one core network to another.

    摘要： While a device is served on a first wireless connection on a first carrier that has a first center frequency, a determination will be made that a threshold high probability of precipitation is forecast for a location of the first wireless connection. In response to at least that determination, but before the forecast precipitation occurs, the device will then be reconfigured from being served on the first wireless connection on the first carrier to instead being served on a second wireless connection on a second carrier that has a second center frequency lower than the first center frequency, with the reconfiguring being based on the second center frequency being lower than the first center frequency. Proactively switching the device to a lower carrier based on the prediction of precipitation may help to minimize rain fade and associated issues.
