Vendors and operators met in London to discuss business models and the future of Service Delivery Platforms (SDPs) and how these can help the latter increase revenues without growing organically. The topic of SDP has been evolving in parallel with IMS and in some cases their evolution is similar. While both have been referenced as a way to implement new services and generate new revenue streams, neither have reached critical mass and in most cases are regarded as a “utility” rather than a premium enabling technology.
