An IP multimedia subsystem (IMS) network includes a plurality of network elements that are interconnected for directly or indirectly communicating with one another. One of the network elements houses (or embodies) a consolidated subscriber database. The consolidate subscriber database is the only data storage entity in the IMS network for non-transitory storage of consolidated user data (that is, data relating to multiple user), for purposes of carrying out the core communication functions of the network. The user data is data relating to subscribers (e.g., end users) and subscriber services in the IMS network, such as user profile data and data relating to supplementary user services, e.g., call forwarding, call waiting, and the like. The consolidated database replaces the multiple database typically present in an IMS network, thereby lowering operational expenditures and simplifying data management operations.
