A METHOD OF REGISTRATION FOR THE PRIVATE NERWORK TERMINAL TO THE GATEKEEPER BASED ON THE H.323 PROTOCOL

摘要

A method of registration for the private network terminal to the gatekeeper based on the H.323 protocol includes: perform the static network address translation for the H.323 proxy server on the network address translation device, the private network terminal initiates the registration request to the H.323 proxy server; the H.323 proxy distributes the listening port to the private network terminal and modifies the registration address in the registration request into the public network address of the H.323 proxy server and above distributed listening port; H.323 proxy server registers to the gatekeeper. The present invention uses the same public network IP address and different listening port to recognize the different private network terminal so that the registration address transmitted by the private network terminal via the same H.323 proxy server is different. Thereby the gatekeeper can distinguish the different private network terminals and the problem that multiple terminals corresponds to one public network IP address is solved. Meanwhile, the present invention uses the standardH.323 protocol between the H.323 proxy server and the public network gatekeeper and thereby improves the interconnection ability between the H.323 proxy server and the different kinds of gatekeeper.
