Evolution And Planning Research Of ZaoZhuang Unicom Local Transmission Network

With the rapid development of communication technology, the big operators of competition becomes increasingly fierce, the only voice calls business cannot have satisfied people increasingly diverse communication demand, of wireless communication technology business application then become the big operators the fundamentality of income, business application needs to provide more bandwidth, and the capacity of the ground transmission network wireless data aggregation and put forward higher load requirements. At present ZaoZhuang unicom has become mobile+fixed business operators, comprehensive WCDMA technology by China unicom in application, but also to provide a bright future for the China unicom. At the same time WCDMA technology for large capacity data bandwidth requirements, make local transmission network also faced greater challenges. To satisfy the network development, improve users' perception, saving investment, and more security, long-term construction requirements of the local network transmission.At present ZaoZhuang unicom has DuoGe 10 GMSTP levels of transmission plane, carrying ZaoZhuang unicom's 2 G,3 G base station, the key customer of business networking business, etc, with the MSTP etheric etheric business bandwidth increases, the transmission network faces significant pressure, especially the core layer ring network time buttress take up larger, how to faster low cost of integration of existing transmission resources to meet future 3 G business development, by what transmission technology become the focus of attention at present. It firstly expounds the ZaoZhuang unicom local transmission network construction practical needs. Through detailed analysis of the present situation of the existing network, and in the light of unicom WCDMA 3 G business needs to transfer, MSTP, PTN, IP RAN, MSTP++OTN MSTP, major transmission technology, combined with a comparative study of the actual ZaoZhuang unicom, and puts forward some solutions to ZaoZhuang network bottleneck between local networks of the scheme.Through the analysis, in ZaoZhuang now nets on the basis of MSTP+technology and MSTP+OTN technology to realize the traditional voice business and high bandwidth data business, the saving of the separation of the fastest network evolution, applied to finish it, and business base station transmission in the practice application reached the better effect.
