ABSTRACT:
The present invention is to provide a home subscriber server configuration method and system that is accessible in switching to any one of plural HSS servers in a redundant configuration. Information stored in such plural HSS servers (e.g., HSS-A server40A and HSS-B server40B) are synchronized as identical information. When an interrogation for a particular HSS server to be accessed from the I-CSCF server30or the S-CSCF server21is received, the access information for the plural HSS servers40A,40B corresponding to the interrogation is returned after rearranging to the predetermined order of priority to the I-CSCF server30or the S-CSCF server21from which the inquiry is originated. If no response is received from either one of the HSS servers returned from the SLF server50within a predetermined time after the access or if no response is received to the resend operations, the I-CSCF server30or the S-CSCF server21selects the next HSS server from the plural HSS servers and gains access to such HSS server after switching thereto.
