Abstract
Techniques to optimize video-call communications are disclosed. The link quality capability of a wireless video-call session and the requirements of the video-call session are determined. The link quality capability determination is based at least on measurements through the entire communications chain, including user, client device, operating system, application, air interface, cell sector, and backhaul parameters. Those parameters may be determined from static profiles, dynamically determined or be statistically derived. Client device response may include adapting the rate of data captured by a video camera, microphone, or other data capture device used in the video-call session. For video-conferencing scenarios, communications throughput is optimized by consolidating video streams.
