PURPOSE: A method of managing subscriber data for mobile management of an IP multimedia service subscriber is provided to operate another managing server for the mobile management, and to distribute subscriber data requests, thereby reducing signal message load processed by an HSS(Home Subscriber Service). CONSTITUTION: A terminal transmits a signal message to a network(S1), and transmits the signal message to an HLR(108)(S2). The HLR(108) requests to delete subscriber data of an SGSN(Serving GPRS Support Node)(104)(S3,S4), and transmits the subscriber data to the SGSN(104)(S5,S6). The SGSN(104) informs of the successful network access(S8). A subscriber transmits the signal message to the network(S9), and the SGSN(104) requests to set packet connection of a GGSN(Gateway GPRS Support Node)(105)(S10,S11), then the subscriber transmits a position registration request message to the network(S13). A P-CSCF(Proxy-Call State Control Function)(101) relays the message to an I(Interrogating)-CSCF(122)(S14). The I-CSCF(122) inquires of an IMMS(IP Multimedia Mobility Management Server)(100) for information of an S(Serving)-CSCF(123)(S15,S16). The I-CSCF(122) relays the signal message to the S-CSCF(123)(S17). The S-CSCF(123) transmits an authentication data request to the IMMS(100)(S18), and the IMMS(100) transmits data to the S-CSCF(123)(S19). The S-CSCF(123) requests the subscriber data of the IMMS(100)(S20), and the IMMS(100) transmits the data to the S-CSCF(123)(S21). The S-CSCF(123) informs of the successful registration(S22,S24). |
