Abstract:
1. A method for providing enterprise services in an Internet Protocol (IP) Multimedia Subsystems (IMS) based service provisioning network, the method comprising: receiving a message being an originating service request from a terminal endpoint device associated with an enterprise network via an interconnect border control network node, the interconnect border control network node functioning to provide service requests associated with the enterprise network with a direct entry point of the IMS based service provisioning network, thereby avoiding using a Proxy Call/Session Control Function (P-CSCF) as an entry point of the IMS based service provisioning network, and the originating service request being a request that originates in the enterprise network for a Session Initiation Protocol (SIP) based session service; adding, by the interconnect border control network node, information to the originating service request; based on the information added to the originating service request by the interconnect border control network node, determining a serving network node to assign to the originating service request, wherein the added information includes a route header that points to an Interrogating Call/Session Control Function (I-CSCF) of the IMS based service provisioning network, and wherein the serving network node is a Serving Call/Session Control Function of the IMS based service provisioning network, wherein the originating service request is routed on the basis of a profile stored on a subscriber server, the profile associating users with services of the IMS based service provisioning network; forwarding the originating service request to the assigned serving network node; and by forwarding the originating service request from the assigned serving network node to an application server associated with the IMS based service provisioning network, causing the application server to execute at least one originating service on the basis of the originating service request.
