Abstract: A communications device sends an invite to a communication session to multiple target devices and receives first and second media streams from first and second target devices prior to receiving a signaling indication that any of the multiple target devices accepts the invite. The communications device selects between the first and second media streams based upon (i) information contained in a first packet of the first or second media streams and/or (ii) signaling information that indicates a forking context for the communication session. The communication device plays the selected media stream prior to receipt of the signaling indication. In another embodiment, after sending the invite, the communications device detects a network address and port information from (i) a media stream from a target device, and (ii) from a signaling message. The communication device sends media to the target device based on the detected information.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided where, at a first wireless node, a weighted average of a frame loss rate is determined for a plurality of frames transmitted from a second wireless node using a first codec; feedback is transmitted to the second wireless node based at least in part on the frame loss rate; and one or more frames are received from the second wireless node using a second codec, responsive to transmitting the feedback. Also, transmitting from a first wireless node a plurality of frames to a second wireless node using a first codec; receiving frame loss rate information from the second wireless node responsive to the transmitting; selecting a second codec, based at least in part on the frame loss rate information, and transmitting a second plurality of frames to the second wireless node using the second codec.

Abstract: Aspects of the present disclosure provide techniques to speed up and improve silent redial success rates in wireless communications. A user equipment (UE) may determine how to attempt retrying a mobile originated (MO) call and procedures for selecting a subsequent system for attempting the call based, at least in part, on a restriction status of the call and a detected failure.
