Abstract: An operating method for a media stream transmission key includes: detecting, by a media gateway, lifetime status information of a media stream transmission key; and when the media gateway determines that a lifetime of the media stream transmission key expires, executing, by the media gateway, a media stream transmission key lifetime expiry behavior according to an instruction of a media gateway controller. The embodiments of the present invention fill a technical gap that an operation is performed on a lifetime status of a media stream transmission key in an architecture where an MG and an MGC are separated.

Abstract: A method for adjusting media stream transmission bandwidth and a related apparatus are provided. A media stream sending end acquires scores that are given, according to identifiers of multiple media streams, by a media stream receiving end to the media streams, where the multiple media streams are transmitted at a same transmission port, and these identifiers are described based on media stream content; when it is detected that congestion occurs or congestion is resolved, the media stream sending end performs transmission bandwidth adjustment on a corresponding media stream according to these scores, and therefore media stream transmission bandwidth adjustment may be performed, based on the media stream content, on the multiple media streams transmitted at the same transmission port.
