SUBSCRIBER PROFILE IMPLEMENTING AND TRANSFERRING METHOD IN IP MULTIMEDIA HOME SUBSCRIBER SERVER

摘要

PURPOSE: A subscriber profile implementing and transferring method in an IP(Internet Protocol) multimedia HSS(Home Subscriber Server) is provided to facilitate searching of a subscriber database by designing an IP multimedia service subscriber profile in a hierarchical structure by services and functions. CONSTITUTION: An HSS reads system information from a database, initializes various variables and turns in a standby state to wait a message. When an SAR(Server-Assignment-Request) message is received from a CSCF(Call Session Control Function), the HSS checks whether a received public ID and a private ID are identical to those in the database. If they are identical, the HSS brings every content of a service profile where the public ID belongs. Each content is constructed in an AVP(Attribute Value Pair) form and coded and a subscriber profile is entirely transmitted through an SAA(Server-Assignment-Answer) message to the CSCF.
