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. |

1. An operating method for a media stream transmission key, comprising:
receiving, by a media gateway, a key expiry event including a key lifetime expiry behavior parameter delivered by a media gateway controller, wherein the key lifetime expiry behavior parameter instructs the media gateway to execute, when the media stream transmission key expires, a corresponding key lifetime expiry behavior; detecting, by the media gateway, lifetime status information of a media stream transmission key according to the received key expiry event; and when the media gateway determines that a lifetime of the media stream transmission key expires, executing, by the media gateway, the key lifetime expiry behavior corresponding to the key lifetime expiry behavior parameter delivered by the media gateway controller; wherein the key lifetime expiry behavior corresponding to the key lifetime expiry behavior parameter comprises at least one of the following:
closing a media stream and sending a media stream close message, orreporting the key expiry event to the media gateway controller, without sending a media stream close message, wherein the reported key expiry event carries a key expiry indication parameter which indicates whether or not the media stream transmission key is still used. |
