Abstract: A device implementing a system for audio-video conferencing using multiple stream identifiers includes a processor configured to receive, from a sending device, indication of a first content stream and a first stream identifier, and indication of a second content stream and a second stream identifier associated. The first content stream and the second content stream correspond to different bit rates of streaming content. The processor is configured to receive, from a receiving device, a request to subscribe to the second content stream, the request including the second stream identifier, and receive, from the sending device, an indication that the second stream identifier has been associated with the first content stream. The processor is configured to forward, to the receiving device, the first content stream based on the request to subscribe to the second content stream and on the indication that the second stream identifier has been associated with the first content stream.

Abstract: This disclosure relates to inter radio access technology management for audiovisual calls. Wireless link availability and suitability for an audiovisual call may be evaluated for each of a first radio access technology and a second radio access technology. One or more wireless links on which to establish an audiovisual call may be selected based on the evaluations. The audiovisual call may be established on the selected wireless link(s). Wireless link availability and suitability for an audiovisual call may be monitored during the audiovisual call and decisions on whether to perform handover to a different wireless link and/or media duplication on multiple wireless links may be made based on the suitability for an audiovisual call of available wireless links.
