Abstract
In an Internet Protocol Multimedia Subsystem (IMS) network in which multiple subscriber data servers are deployed with partitioned subscription data for users, a subscriber location function (SLF) is used to proxy queries to a subscriber data server (such as an HSS) in which subscription data for a user can be found. The SLF receives a query for the subscriber data server, looks up the address of appropriate subscriber data server and proxies the query to the appropriate subscriber data server. Preferably, the SLF is co-located with a subscriber data server.
