Abstract

The IP Multimedia Subsystem (IMS) as defined by the 3GPP emerges as blueprint for a central architecture to provide Next Generation Network (NGN) services. As an overlay architecture for IP based access networks, it provides standardized interfaces to services which will merge the advantages of traditional telephony networks with the benefits of Internet services. The Open IMS Core[1] project of the Fraunhofer Institute FOKUS which is described in this article started in 2006 as an Open Source initiative targeted at all parties interested in the research development of NGN services and IMS testbeds. The Open IMS Core consists of Call Session Control Functions and a Home Subscriber Server and aims to fill the void in the Open Source software landscape with flexible solutions that have proved their conformance and performance in several national and international R& D projects. This article highlights the challenges in the development of the components and provides insights on major implementation details as well as for their performance. Ex- amples of the usage of the Open IMS Core will illustrate how IMS Open Source software helps not only rapid, but also efficient, flexible and powerful design, development and testing of NGN components and services.
