Abstract: A method and system to help control message routing in a scenario where a client device is registered with a media system via a first network and the media system is configured by default use the first network as a primary route for routing messages to the WCD. Per the disclosure, the media system will detect, while the client device is so registered via the first network, that a second network is serving the client device with a voice call, and the media system will responsively be reconfigured to use the second network as a primary route for routing of messages destined to the client device. Further, the media system may then subsequently detect that the voice call has ended, and the media system may responsively revert to being configured to use the first network as the primary route for routing of messages destined to the client device.

Abstract: A method and system for handover of a wireless communication device (WCD) from a source base station to a target base station that is a relay base station. The source base station may engage in procedure to handover the WCD to the target base station. A determination may be made as to whether or not the target base station is a relay base station with a wireless backhaul. If the target base station is determined to be a relay base station with a wireless backhaul, then the source base station may transmit to the WCD on an air interface a message containing a particular identifier for use by the WCD in a contention-free random access request to the source base station. In the event that the handover fails, the WCD may make a contention-free random access request to the source base station to regain access through the source base station.

Abstract: One embodiment takes the form of a method carried out by a base station. The method includes the base station serving a wireless communication device (WCD) on a given air-interface resource. While serving the WCD, the base station may receive a data packet from the WCD. In response, the base station may update the data packet to include an indication of the given air-interface resource on which the base station is serving the WCD. The base station may then transmit the updated data packet for receipt by one or more gateways.

Abstract: A method and corresponding system to help manage user equipment device (UE) transmission power, specifically in a scenario where the UE was being served by a base station on a first carrier frequency and the UE is then going to communicate with a base station (whether the same or another base station) instead on a second, different carrier frequency. As disclosed, a UE may determine, based on communication by the UE on the first carrier frequency, a baseline initial transmit power for the UE to use for an initial transmission from the UE to a cellular base station on the second carrier frequency. Responsive to the second carrier frequency being different than the first carrier frequency, the UE may adjust the baseline initial transmit power to establish an adjusted initial transmit power. The UE may then engage in the initial transmission using the adjusted baseline initial transmit power.

Abstract: A method and apparatus in which (i) a user equipment device registers with a first radio access network (RAN) that provides connectivity with a transport network, (ii) once registered with the first RAN, the device then registers via the first RAN and transport network with a call server, and (iii) in response to the device registering with the call server, but before the device then engages in a call served by the call server, the device registers via the first RAN with a second RAN. The method may thereby help to expedite later handover of a call served by the call server from being via the first RAN to being via the second RAN. Further, by the second RAN registration being conducted in response to registration of the device with the call server, the method may help to ensure usefulness of the registration of the device with the second RAN.
