Network address translation traversal system and method for real-time communications

摘要

A network address translation traversal system and method for real-time communications are provided. The network address translation traversal system includes a user terminal equipment, a network address translation device, a signaling control system and a peer terminal. The user terminal equipment is in a private network, while the signaling control system and the peer terminal are in a public network. The signaling control system is configured to instruct the network address translation device to create a network address translation mapping for a real-time communication connection. The peer terminal is configured to create the real-time communication connection with the user terminal equipment via the network address translation device directly according to the network address translation mapping.
