Research On Service Composition In IP Multimedia Subsystem

With the development of mobile communication technology and users of the continuous demand for new business, how to effectively develop, deploy, manage and control operations, to provide users with smooth business experience is the industry's urgent problems at this stage. IMS is also called the IP Multimedia Subsystem. It can provide users with diversified multimedia business applications. IMS is recognized as the core technology of NGN networks as well as a solution for mobile and fixed network convergence, an important guarantee for the introduction of voice, data and video triple integration differentiation.From the view of application composition in IMS network, this paper analyses the business structure of IMS network in depth and the trigger mechanism, focusing on different business interaction and composition for study. This article firstly gives a brief introduction of background for IMS network and the development process of the IMS network architecture, operational framework and the different application servers supported by IMS network, carding various types of applications in the future IMS network. The Following is a detailed analysis and summarizations about mechanisms and specifications for the IMS service composition. By analyzing the advantages and disadvantages of each type of mechanism, we sum up a feasibility scenario. Then we select an alternative business simulation and analyze simulation results to verify the theoretical analysis before. Finally, this paper provides relevant recommendations on the future network deployment issues that may arise to.
