SYSTEM AND METHOD FOR COMMUNICATION OF SIP MESSAGES

摘要

PURPOSE: A system for transceiving SIP messages and a method thereof are provided to minimize a necessary calculation quantity for tunneling using a method for wrapping a SIP(Session Initiation Protocol) message using a HTTP(Hypertext Transfer Protocol) packet. CONSTITUTION: A SIP(Session Initiation Protocol) client(110) generates SIP messages. A user terminal(102) receives the SIP messages from the SIP client. The user terminal generates a combined packet for a tunneling header in the received SIP message. The user terminal includes an external transceiver module which transmits a generated packet to a SIP broker server(104). The SIP broker server eliminates the tunneling header by receiving the packet from the external transceiver module inside the user terminal. The SIP broker server transmits the SIP message having no tunneling header to a SIP proxy server(106).
