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, 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 as a part of the enterprise mobile network.
