8. An apparatus for managing information in a system providing an integrated service in an ALL-IP network, comprising:
-
at least one home subscriber server (HSS) for managing subscriber information (profile) corresponding to ID information of at least one terminal;
a call session control function (CSCF) for generating an inquiry message requesting unique information of the HSS corresponding to the ID information of each terminal in response to receiving a service request message from the at least one terminal, and obtaining subscriber information from the HSS based on a received response message;
a subscription locator function (SLF) for translating the inquiry message to a domain name server (DNS) inquiry message for transmission in response to receiving the inquiry message generated by the CSCF, and translating a received DNS response message to a response message for transmission to the CSCF; and
a domain name server (DNS) for managing the unique information of the respective HSSs, retrieving the unique information of the HSS corresponding to the ID information of each terminal in response to receiving the inquiry message from the SLF, and transmitting a DNS response message including the retrieved unique information to the SLF. - View Dependent Claims (9)
