Abstract:
1. A method for implementing Internet Protocol (IP) cross-domain interconnecting between a calling IP domain and a called IP domain, wherein the calling IP domain comprises a first Media Gateway Controller (MGC) and a first Media Gateway (MG), the called IP domain comprises a second MGC and a second MG, and the calling IP domain connects to the called IP domain through a Border Media Gateway (BG), wherein the method comprises: receiving, by the first MGC, a call request based on H.248 from the first MG, wherein the call request comprises calling information, called information and settings of calling media streams; forwarding, by the first MGC, the call request to the second MGC; forwarding, by the second MGC, the call request to the second MG; reporting, by the second MG, a call acceptance including settings of called media streams to the second MGC, wherein the call acceptance is judged by a called user connecting to the second MG according to a preset white list or black list; forwarding, by the second MGC, an interconnecting request to the BG, wherein the interconnecting request comprises IP domain information of the first MG, the settings of the calling media streams, IP domain information of the second MG and the settings of the called media streams; and creating, by the BG, media streams from the BG to the first MG and media streams from the BG to the second MG, wherein the media streams from the BG to the first MG are created according to the IP domain information of the first MG and settings of the calling media streams, the media streams from the BG to the second MG being created according to the IP domain information of the second MG and settings of the called media streams.
