For the incoming era of digital convergence and wireless universal service, users can easily access and use internet services anytime anywhere through many ways. That means whether a service and network provider can provide a high quality of data transformation network will be one of key points to sustain competition in business. Despite there are lots of Operations Support Systems (OSS) support in Chunghwa Telecom, we still lack an automatic traffic dispersion workflow management and integrated tracking mechanism among OSS for engineers to efficiently control trunk reengineering processes when traffic congestion occurs. To make up the deficiency, we start to research and design an integrated traffic dispersion work management framework, on which existing OSS can be integrated and engineers can define their own workflow across OSS by different solution. With it, reengineering processes can be easily traced and work efficiency will be improved. In this paper, we will point out the problem that we encountered about existing traffic congestion avoidance operations, and how do we introduce new framework to solve it. Finally, we will use subscriber reallocation operations as a use case to show what benefits we get after introducing new framework.
