Abstract
Latest development shows that telecommunication providers merge their networksinto all-IP-based networks. For this pupose, IMS (IP-Multimedia Subsystem) has been introduced. The architecture allows to deploy application servers providing several telecommunication services ontop of the IMS.
Motivated by the rapidly growing popularity of Web 2.0 applications and the emerging market with value added services on mobile devices, there have been introduced standards to combine the telecommunication and internet domain. The most recent standard is OneAPI which defines some key services in a RESTful design. RESTful Web Services are kept small by directly using the HTTP’s protocol mechanisms which makes them very efficient.
This thesis shows a prototype implementation of a generic REST to SIP interface, and a gateway module translating between specific OneAPI REST messages on a JAIN SLEE Application Server being an event driven platform to SIP. To perfect an example of the complete vertical communication through this AS, we also present an SMS service implementation.
A brief overview of a performance evaluation is given and the results are discussed.
