Enterprise mobile network for providing cellular wireless service using licensed radio frequency spectrum and the session initiation protocol
First Claim
1. A mobile switching subsystem (MSS) for use with a base station subsystem (BSS) deployed on a premises of an enterprise to provide wireless service within a coverage area associated with the enterprise using licensed radio frequency spectrum as a part of an enterprise mobile network having local subscribers thereof, the licensed radio frequency spectrum used by a public land mobile network to provide wireless service to public subscribers of the public land mobile network and to roaming subscribers, the MSS comprising:
- switching functionality that comprises a Session Initiation Protocol (SIP) proxy function, a SIP redirect function, and a SIP register function;
a visitor location register (VLR) function that comprises a SIP location function; and
a home location register (HLR) that is configured to store SIP profiles;
wherein the switching functionality, VLR function, and HLR function are configured to provide the wireless service within the coverage area within the enterprise using the licensed radio frequency spectrum to the local subscribers of the enterprise mobile network as a part of the enterprise mobile network and to the public subscribers and the roaming subscribers as a part of the public land mobile network.
