1. An enterprise mobile network for providing wireless service within a coverage area associated with an enterprise using licensed radio frequency spectrum, the enterprise mobile network comprising:
- a base station subsystem (BSS) deployed on a premises of the enterprise to provide wireless capacity within the coverage area using the licensed radio frequency spectrum; and
a mobile switching subsystem (MSS) communicatively coupled to a public land mobile network;
wherein the BSS is communicatively coupled to the MSS using an Internet Protocol (IP) network;
wherein the MSS is configured to implement at least some networking switching subsystem (NSS) functions for local subscribers of the enterprise mobile network; and
wherein the MSS comprises a Session Initiation Protocol (SIP) user agent to communicate with at least one SIP server, wherein the SIP user agent is configured to function as a first SIP client when communicating with the SIP server; and
wherein the MSS is configured to use the SIP user agent to establish a communication session between a mobile device that wirelessly communicates with the BSS using the licensed radio frequency spectrum and a second SIP client coupled to the SIP server.

Abstract
Support for Session Initiation Protocol (SIP) devices is provided in an enterprise mobile network that provides wireless service within a coverage area associated with an enterprise using licensed radio frequency spectrum. In various embodiments, support SIP devices is provided by, for example, incorporating SIP user agent in a mobile switching subsystem or in a base station subsystem or by incorporating SIP server functionality into a mobile switching subsystem.
