| With the rapid development of Internet, network applications have penetrated into all aspects of social life, and our people have entered the information age, while the network also greatly changes people's daily life. NGN (Next Generation Network) is used extensively to describe the future telecommunications networks. With the coming of NGN, the network scale will be even larger; the structure will be much complex, and the traffic will be much enormous and network service will be gained a rapid development once again. Aiming at these characteristics, the Chinese network operators will face a huge challenge. On the one hand, the gradual saturation of market and the increasingly intensity of competition make operators seek the most advanced equipment, systems and management methods in order to constantly creat new business opportunities to meet the challenge. On the other hand, the gradual decrease of operating profit makes enterprises pay more attention to the optimization of the pricing system on Diff-serv applications to attract more users and meet the needs of different types of users, and maximize the revenue. These problems make the research on modeling, analysis, admission control, and pricing scheme in NGN network from the standpoint of operators important and meaningful.In this thesis, the research background, content and structure are outlined in chapter I. The application of pricing scheme using microeconomics to network operation and control is discussed in chapter II. The current research on resource allocation using pricing scheme to network is also introduced as a leading of the following discussion of the revenue. The problems brought by the existing popular single billing mechanism are analyzed, and the billing policy based on business priorities which can distinguish different kinds of traffic using pricing scheme is brought forward in chapter III. Finally, the simulation based on the revenue of pricing scheme is carried out, and the simulation results are analyzed. And the implementation of pricing scheme according to the approach of user forecast is discussed in chapter IV, and the policy of increasing the revenue by introducing a reasonable price scheme through the statistics, analysis, and forecast of user behavior in NGN is also introduced. Furthermore, a forecasting model and an adjusting price scheme through forecast are proposed, and the simulation and analysis are carried out as well. In this thesis, the simulation results which based on the revenue of pricing scheme show that the revenue is increased because of admitting more high paid users, and the quality of service network is thereby guaranteed. Addtionally, through effectively reasonable price adjustment mechanism, the revenue can be significantly increased. In accordance with the research, the service provider can easily make suitable management and decision.At the end of this thesis, the research work is summarized, and the way of future work is suggested. |
