Title: Method and system of registration in ip multimedia subsystems
Inventor: CHUNG JE DON
IPC: H04W8/24
Filed: 2007-09-20
Abstract: A communication network registration method of an IP multimedia subsystem and a system thereof are provided to simplify the procedure required when a user terminal registers for a communication network, thereby reducing the consumed radio resources. A P-CSCF(Proxy-Call Session Control Function)(73) receives and stores an intrinsic number from a terminal(10)(S300,S310). The P-CSCF receives the first registration message from the terminal(S210), and then transmits the received message to an S-CSCF(Serving-Call Session Control Function)(77)(S220,S230). In case the authentication for the terminal is not completed, the registration incomplete message is received from the S-CSCF(S237,S238). The second registration message is generated by using the intrinsic number and registration incomplete message(S320). The second registration message is transmitted to the S-CSCF(S250,S260).
