A method and system for realizing media stream interaction are provided. The method includes the following steps: the MGC obtains the public network address corresponding to the media gateway MG in the private network, and the public network address is used as the remote address of the opposite side of the MG; then, the MGC sends the public network address to the opposite side; and the opposite side realizes media stream interaction with the MG in the private network by the public network address. Using this method, the media stream passing through across different IP domains in the media gateway can be realized. Also, a media gateway controller and a media gateway are provided.
