¿µ¹®³»¿ë¿ä¾à REGISTER method is used in a Session Initiation Protocol system primarily to associate a temporarily contact address with an AOR(Address-Of-Record). But, REGISTER does not provide a mechanism to discover proxies in the network topology and record the sequence of them. This standard defines ¡°Path¡± header field which give us such mechanism.
This standard can be used to find and record intermediate proxies. Specially, 3GPP requirement for discovering intermediate proxies during SIP registration can be met.
