Research And Implementation On RCS Application Based On Convergence Network

In the evolution of network convergence, IMS (IP Multimedia Subsystem) is playing more and more important role.To build a new future-oriented information communication network,the IMS basic starting point is organic synthesis the cellular mobile communications network technology and the Internet technology.Extensive use of Internet, not only greatly promoted the development of IP technology, but also changed people's way of thinking and interactive mode.Its biggest success is the ability to easily and flexibly provide various information services, and quickly and easily create new services according to the needs of customers.RCS (Rich Communcation Suite) application was born in the IMS and Internet convergence process.Laboratory Section of the issue take full advantage of research projects with Ericsson-the RCS web-based converged network application.To propose a converged network based on the RCS application architecture.And to fully verify the feasibility and structure of which appears to resolve authentication and privacy policies, such as management issues.This paper focuses on the integration of business applications in the network capacity, the survey industry background, full investigation of related technologies.Based onthe converged network, in-depth study of the convergence process at the heart of the IMS network architecture, key technology and business applications.Introduces the traditional RCS-based IMS network applications and business background.Outstanding the RCS-based research meaning in converged networks.This paper designed the RCS web application server architecture and operational mechanism for converged networks.This architecture differs from traditional Internet access which through a proxy server to achieve the process of IMS core network.By REST (Representational State Transfer) in the form of effective protection under the premise of low coupling and high efficiency of communication.Designed the RCS web application privacy management strategies reference to the REST-form privacy management strategy.Put forward a solution of RCS privacy policy, and on this basis are discussed in detail in the presence RCS information processing, document processing and authorization rules presence information subscription license mechanism.Design and implement RESTful client communications interface, and connected with the RCS architecture to achieve IM communication process to confirm the correctness and feasibility of the architecture.
