Abstract:
1. A method for implementing media gateway function, comprising: receiving a first signaling message, wherein the first signaling message is generated by a Mobile Switching Center (MSC) serving device in the processing of the base station application layer or the processing of the media gateway control application layer of the MSC serving device, and is sent by the MSC serving device; determining to perform a processing of a base station application layer or a processing of a media gateway control application layer according to a source Internet Protocol (IP) address and port as well as a destination IP address and port of a Simple Control Transmission Protocol (SCTP) link, wherein the SCTP link is indicated by the first signaling message; obtaining a destination IP address of traffic data; if it is determined that the processing of the media gateway control application layer is to be performed, routing the traffic data to a destination device according to the destination IP address of the traffic data; receiving a notification signaling message sent by the MSC serving device in a processing procedure of an H.248 protocol layer; connecting to a Media Resource Function Processor (MRFP) of a media gateway according to the session description information including the IP address and port of the media resource received from the MRFP to obtain a media resource; notifying the MRFP of preparing the media resource before receiving the notification signaling message sent by the MSC serving device; and returning session description information including IP address and port of the media resource to the MSC serving device upon the media resource being prepared, wherein the notification signaling message comprises: the session description information including IP address and port of the media resource received from the MRFP.
