Abstract

The IP Multimedia Subsystem (IMS), standardized by the 3GPP, is the most promising contender for replacing legacy, voice-dedicated mobile networks with an All-IP technology. As 3GPP IMS standards are in their embryonic state it becomes very crucial to test IMS clients during their development on a platform that simulates the IMS network. IMS client testbed also allows the developers to experiment all error circumstances which are not possible on a live network. Furthermore, it is also very costly to use an operator's live network for testing purpose. This paper highlights challenges involved and our experience of building an IMS client test bed using open source tools like OpenIMScore.
