IP MEDIA RATE ADAPTATION

摘要

A method of managing congestion in a packet switched access network. The method is performed within a packet core network providing a transit network for a user media stream sent from a sending device via the packet switched access network. Actual or potential congestion in the packet switched access network associated with said user media stream is identified. In response to such identification, the sending device is notified of the actual or potential congestion by inserting a notification of congestion into control signalling of the media stream.
