Abstract:

Centralizing and converging of charging and billing system is the important direction of system construction of the internet era.Analyzing the current provincial centralized charging and billing systems,the trends and challenges of system construction were proposed.Considering the difficulties and the achievements of this area,the paper presented a feasible technical solution and described the key points of it.With the development of 3G,the dynamic policy control of mobile network has become the urgent business requirement for the operators.On the basis of in-depth study of existing policy control and charging framework,a PCC based implementation solution for converged policy control and charging was proposed.The simulation and verification of flow prepaid card show that the framework can solve the problems of dynamic policy control and converged charging better than the existing system frameworks,thus can reduce customer complaints and improve operational efficiency.

Key words: policy control, converged charging, PCC, flow prepaid card
