Research And Implementation Of Open Architecture Based On IMS And The Designation Of Innovative Services

In recent years, the rapid development of Internet applications has a strong impact on mobile network operators in the services of voice and SMS. Mobile Internet applications provide users with a rich variety of business; however, operators can provide various types of services with IMS (IP multimedia subsystem) as well. The significance of the thesis is to use the IMS network to improve the existing open platform of operators so that operators can open multimedia business based on IMS network platform, which makes operators more competitive against Internet.The current status of telecommunications networks open structure and internet open structure was researched firstly, including open architecture, available APIs and open API technology. Comparing the open structure technology of the Internet networks and operators’ network, the shortcomings of the existing operator’s architecture of opening capability was analyzed. Then we proposed the architecture of opening capability based on IMS, which would make the platform IP-based, access independent and enable the platform to provide rich multimedia services to third-party developers.We concluded an optimal plan to open capabilities with IMS. On this basis, an overall IMS open architecture and the key modules of it were described.Then we implemented the proposed IMS open structure, selected and designed the type of open APIs. We built an IMS environment with an open source project Open IMS Core and an open framework was selected to open API.Finally, we provided detailed description and designation of a new service’s function in order to test the platform.
