METHOD, SYSTEM AND DEVICE FOR REALIZING NETWORK ADDRESS TRANSLATION PASSING

摘要

A method for implementing NAT traversal is disclosed herein. The first MGW and the ICE mechanism supporting device obtain the local candidate information and the candidate information of the peer end; the first MGW and the ICE mechanism supporting device perform connectivity check according to the candidate information; and the first MGW and the ICE mechanism supporting device transmit media streams according to the result of the connectivity check. A system and a device for implementing NAT traversal are also disclosed. The method, the system and the device under the present disclosure improve stability of transmitting media streams in a network inclusive of an MGC and an MGW (for example, an NGN).
