Enterprise mobility
First Claim
1. A method comprising:
- receiving a first carrier session message from a multimedia subsystem associated with a carrier network and comprising a carrier user identifier identifying a user associated with a communication session;
identifying an enterprise user identifier corresponding to the carrier user identifier for the first carrier session message, wherein the enterprise user identifier is different from the carrier user identifier and at least one of the enterprise user identifier and the carrier user identifier includes a session initiation protocol (SIP) identifier;
creating a first enterprise session message corresponding to the first carrier session message and comprising the enterprise user identifier; and
forwarding the first enterprise session message into an enterprise network, wherein the first enterprise session message is an initial message transmitted into the enterprise network associated with the first carrier session message.

Abstract
The present invention provides a service node, which extends the services of a carrier'"'"'s multimedia subsystem (MS), such as an IP multimedia subsystem (IMS), to enterprise networks in an efficient and effective manner. As such, MS subscribers gain access to enterprise services in addition to the carrier'"'"'s services provided via the carrier'"'"'s circuit switched subsystems (CS) and packet subsystems (PS). The service node acts as a liaison between enterprise application servers and the MS, such that the enterprise application servers appear as MS application servers to the MS. The service node provides user identifier and protocol translation between enterprise and MS user identifiers and protocols, respectively. As such, enterprise application servers can access the MS as well as be accessed by the MS to support user mobility, with continuity of services, between the enterprise and carrier networks.
