The IBM® WebSphere® IP Multimedia Subsystem Connector provides interfaces and services used when developing applications that must interact with elements within the IMS core environment.
The IBM WebSphere IP Multimedia Subsystem Connector–consisting of the IBM WebSphere IMS™ Service Control Interfaces Component (ISC Interfaces), the Diameter Enabler, and the Trust Association Interceptor (TAI) security component–provides interfaces and services for use in developing applications that interact with elements in the IMS core environment.
Use of the WebSphere IMS Connector enables the application programmer to write applications that run in the WebSphere Application Server environment and interact with the IMS Control Plane through communication with an S-CSCF. This reference point between an application server and the S-CSCF is called IMS Service Control (ISC).
Because this reference point defines SIP as the protocol for communication, and because SIP is built into the base WebSphere Application Server product, there is no need to install additional code from the WebSphere IMS Connector. The Connector provides supporting services for such applications, and provides the license for future maintenance and support for such applications.
While it is not strictly a part of the WebSphere IMS Connector, the IBM WebSphere Telecom Toolkit provides sample applications. These applications demonstrate how to develop ISC applications that run in an application server with the WebSphere IMS Connector installed.
The IBM WebSphere Diameter Enabler Component, consisting of the Diameter Enabler base and Diameter Web services, is a major component of the WebSphere IMS Connector. The Diameter Enabler provides a Web service interface that allows Diameter applications to send and receive subscriber profile information, send accounting information, and manage online charging.
The WebSphere IMS Connector provides a TAI security component that provides integration for the IBM WebSphere software for Telecom products and other applications into the authentication protocols of the IMS core network. This component intercepts HTTP and SIP service requests to all IMS service plane components, verifies the sending element, consumes IMS-compliant identity information passed to it in HTTP/SIP headers, and propagates this information in a format compatible with WebSphere Application Server-based security.
