METHOD OF CONNECTING SESSION BASED ON SIP IN A CLOSED NETWORK ENVIRONMENT, CAPABLE OF CONNECTING A RECEIVING TERMINAL AND A ORIGINATING TERMINAL THROUGH A PERFORMANCE OF SERVER DEMON OF ORIGINATING TERMINAL IN CASE OF ONLY THE RECEIVING TERMINAL EXISTS IN THE CLOSED NETWORK

摘要

PURPOSE: A method of connecting session based on sip in a closed network environment is provided to perform one to one session connection between an originating terminal and a receiving terminal through performance of originating terminal having server daemon, thereby improving speed and accuracy of a session connection.;CONSTITUTION: An IP address of an originating terminal does not exist in a closed network, the originating terminal practices a server daemon(S402,S404). The originating terminal and a receiving terminal connects to the server daemon(S406). If the IP address of the originating terminal exist in the closed network, a gateway practices relay server(S408). The originating terminal and receiving terminal connects to the relay server(S410).;COPYRIGHT KIPO 2010
