Embodiment Construction
[0027] figure 1 A flowchart of a communication method based on network address translation provided by an embodiment of the present invention, such as figure 1 As shown, the method includes:
[0028] Step 100, the network address translation NAT traversal server receives the registration message sent by the mobile terminal, and the registration message includes address information, port identification and session identification;
[0029] When two mobile terminals under different private networks perform IP communication, first negotiate the IP address of the NAT traversal server occupied by the two mobile terminals for communication interaction and the port identifier of the port on the NAT traversal server, and obtain the IP address of the port on the NAT traversal server. The corresponding session identification is communicated and exchanged, and then each mobile terminal sends a registration message to the NAT traversal server, and the registration message includes the add...
