[0007] In the above method, both parties that need to communicate establish their own business platforms, each new business requires a business platform, and resources between different business platforms cannot be shared
Moreover, in the case of a limited scale of business platform deployment, it is easy to cause the flow of communication between terminals to detour

The invention discloses a universal conversion platform, server, system and method for inter-terminal communication. The method includes: the universal conversion platform receives the mapping binding relationship sent by the server through the public interface, the binding relationship includes the mapped IPv4 or IPv6 public address and port of one of the communication parties, and the mapping of the other party of the communication parties IPv4 or IPv6 public address and port; the universal conversion platform receives the data sent by one of the communication parties, and sends the data to the other party of the communication parties according to the binding relationship. The present invention can realize the communication between IPv4 terminals located in different local area networks and the communication between terminals (IPv6 terminal and IPv4 terminal) located in different address families under the symmetrical NAT environment.
Description
technical field [0001] The invention belongs to the field of IP, and in particular relates to a general conversion platform, server, system and method for communication between terminals. Background technique [0002] When public IPv4 addresses are gradually exhausted, operators can only complete user network access by assigning private IPv4 addresses or IPv6 addresses to users. [0003] Since most of the current Internet content is still based on IPv4, after allocating such addresses to users, operators also need to consider how to implement private IPv4 addresses or IPv6 addresses by deploying NAT (Network Address Translation) devices For conversion to public IPv4 addresses, in general, operators add carrier-grade network address translation equipment (CGN, Carrier Grade NAT) at the egress of the MAN. [0004] After the operator deploys the NAT device in the network, it is difficult to realize the direct communication between the original devices that can obtain the publi...
