Published back in April, is a new document on developerworks, “Develop an offline charging application based on WebSphere IMS Connector” which looks a very useful document so i figured it would make sense to bring it to your attention…. (link now broken)

This article describes how you can develop an offline charging application using the Rf interface in IBM® WebSphere® IP Multimedia Subsystem (IMS) Connector V6.2, presents a sample asynchronous offline charging adapter to enable multi-threaded throughput of the Rf client, and discusses performance tuning based on the Rf interface.


IBM WebSphere IP Multimedia Subsystem Connector V6.2 (hereafter referred to as WebSphere IMS Connector) is an important component of the IBM Service Delivery Platform for Telecommunications. In the IP Multimedia Subsystem (IMS) architecture, the WebSphere IMS Connector connects SIP applications with IMS core elements and provides functions of offline charging (through the Rf interface), online charging (Ro interface), and subscriber profile management (Sh interface).

This article describes how to develop an offline charging application, leveraging the Rf interface in WebSphere IMS Connector V6.2. An asynchronous offline charging adapter that implements an asynchronous callback interface to enable multi-threaded throughput of the Rf client is then presented. This discussion concludes with a look at performance tuning with WebSphere IMS Connector.

This article assumes a basic understanding of the IP Multimedia Subsystem, Diameter protocol, Java™ programming, and Web services standards.
