SYSTEM FOR PROCESSING REGISTRATION INFORMATION OF USER AGENT IN NETWORK AND METHOD THEREFOR |
摘要 |
PURPOSE: A method for processing registration information of a UA(User Agent) in a network is provided to define an SIP(Session Initiation Protocl) deregister method, and to efficiently process a network initiated deregister procedure, thereby removing a processing overhead for continuously monitoring whether registration information of a UA is available. CONSTITUTION: A UA requests current self contact information to be registered(5A). A register message is transmitted to an I(Interrogating)-CSCF(Call Session Control Function)(5B). The I-CSCF transmits the register message to an S(Serving)-CSCF(5C). The S-CSCF informs an HSS(Home Subscriber Server) that the UA is registered(5D), and transmits a 200 OK response message(5E-5G). If the HSS deletes UA registration information(5H), the HSS transmits a deregistration notification message to the S-CSCF(5I). The S-CSCF transmits a deregister message to the UA(5J-5L). The UA transmits a 200 OK message as a responses(5M-5O). A proxy server receives a deregister message when a registrar transmits the deregister message to the UA(5P-5S).
