Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request to a network entity to establish a voice communication session with another UE that may be subscribed to a video service. The UE may transmit an indication of a video streaming parameter for the video service for streaming one-way video transmissions from the network entity to the UE for display during establishment of the voice communication session. The UE may transmit an indication of an updated video streaming parameter to the network entity to reduce the video quality for the video service. The network entity may reduce the video streaming quality for the one or more one-way video transmissions to the UE based on the updated video streaming parameter.

Abstract: A method and apparatus improve Voice over Internet Protocol (VOIP) call setup success rate and latency. The method provides for attempting a mobile originated packet switched call, by a user equipment (UE), across a packet switched network with a transmission control protocol (TCP) connection of the Internet Protocol multimedia subsystem (IMS) session. A silent redial of the mobile originated packet switched call is performed in response to a failure of the mobile originated packet switched call, via a circuit switched network. A keep alive message is transmitted over the packet switched network after the circuit switched network call, which allows reconnection to the packet switched network.
