Open source IP multimedia subsystem core and testbed exploration areas

The Open IMS playground@FOKUS represents a pioneering NGN testbed, which currently will be interconnected with other remote NGN testbeds around the world, including those in Africa. This paper has as principal objectives, the provision of a brief overview about the IMS Technology, to describe the Open IMS Core and to describe the benefits that joint testbed cooperation and experiments can bring to the sub-Saharan Africa Countries. Such testbed interconnection enables the exchange of knowhow and the performance of international R&D activities with participation from local academic and industrial partners. Possible exploration areas that the IMS infrastructure can bring are also described.
