1. A system for identifying an IP multimedia subsystem (IMS) cluster node adapted to serve a particular subscriber, the system comprising:

  • an IMS cluster location node including a processor, the IMS cluster location node further including;

    an IMS cluster node location database embodied in a non-transitory computer readable medium and including entries corresponding to IMS subscriber identifiers and identifying IMS cluster nodes for serving subscribers corresponding to the IMS subscriber identifiers; and

    an IMS cluster node location function executable by the processor for receiving IMS registration messages and performing lookups in the IMS cluster node location database for identifying IMS cluster nodes among a plurality of IMS cluster nodes containing information for particular subscribers identified by the IMS registration messages and wherein the IMS cluster location node forwards the IMS registration messages to the identified IMS cluster nodes, wherein at least one of the IMS cluster nodes includes a call state control function (CSCF) and a home subscriber server (HSS) function.
