Design and Implementation of a RESTful IMS API

Web 2.0 has been happening on the fixed Internet side for several years already. This phenomenon has forced traditional Telco operators to consider new business models. One of the possible models is to utilize the IP Multimedia Subsystem (IMS) network architecture. Using the IMS, Telco operators have more control over the data instead of becoming just bit pipes. In addition, operators interest in providing open Application Programming Interfaces (APIs) exposing IMS and network assets has grown. In this paper, a RESTful IMS API implementation, is represented. The design and implementation of the API exposing IMS functionality is shown. In addition, the implementation of a REST application using the API is described.
