Converged application framework for creating web 2.0 - IMS mashups

TELCO operators are moving towards adopting the role of platform providers that enable developers or third parties to create new services for their platform. This is similar to the Web 2.0 application development paradigm where developers use existing frameworks and software development kits to create portable services through mashups (composition) and syndication. To attract a community that would develop these converged services for their platform, there is a pressing need to create a converged (web + IMS) application framework that reduces the development effort, cuts time to market and realizes the dream of a portable service, developed from the composition of elementary services. The existing and cumbersome route so far open to Telcos include working with a Service Capability Interaction Manager (SCIM) and a SIP Application Server (AS). This paper analyzes the motivation, challenges, requirements, benefits and design of a converged application framework for creating mashups using Web 2.0 and IMS. It also discusses how these objectives are met by SailFin CAFE¿ services, exposed to clients through open web interfaces like REST.
