| 摘要 |
The present invention provides a path node determining method, a media path establishing method and a signaling media gateway. The path node determining method comprises: for any one of the signaling media gateways in the IMS network, when receiving a first SDP offer, transmitting a first SDP offer carrying a first path parameter, wherein a network segment identifier of the signaling media gateway is added in the first path parameter of the transmitted first SDP offer; when receiving a first SDP answer for the transmitted first SDP offer, the signaling media gateway judging, according to a second path parameter in the received first SDP answer or the first path parameter in the transmitted first SDP offer, whether the signaling media gateway is a path node; and transmitting the first SDP answer which carries the second path parameter; and transmitting the first SDP answer which carries the second path parameter. Through the technical solutions of the present invention, it is possible to effectively reduce the number of the nodes of a media path and save the resources of media processing equipment. |
