摘要

PURPOSE: A method and a device for processing a call in a service providing system based on an internet protocol, a home subscriber server for call processing are provide to skip registration of relevant S-CSCF when a specific S-CSCT is in and erroneous state or an overload state, thereby maximizing the subscriber distribution effect.;CONSTITUTION: A P-CSCF(Proxy-Call Session Control Function)(104) transmits a registration request message of a terminal(100) to I-CSCF(Interrogate-Call Session Control Function)(106) or relays information between the terminal and a random S-CSCF(Serving-Call Session Control Function). The I-CSCF obtains the S-CSCF address from HSS(Home Subscriber Server)(108). The I-CSCF assigns S-CSCF which takes charge of real registration of the terminal. Each S-CSCF(Servig-Call Session Control Function)(110/1~110/n) provides relevant service to the terminal.;COPYRIGHT KIPO 2010
