Network Resource Analysis Based Metropolitan Area Transport Network Warning Scheme

Transmission network as the basis for the entire telecommunications network, it is an important part to build the information transmission system. With the rapid development of computer technology and the diversification of the client demand for the business, the bearing network performance requirements are also rising.Metro Transmission Network is based primarily on three basic physical networks:gathering room, pipeline and cable. Since 2009, Guangdong Mobile have started the large-scale work for planning and construction of basic network, but a long time the three physical network are planning independently, and no system. With the numbers of network resources and users increase every year and the rapidly expanding of business needs, the work for basic network planning get new opportunities. Basic network resource construction is a sensitive area for business, technology and cost. Meanwhile, the transmission housing and the pipeline network construction environment is very complex, making the construction of the current broadband access network with a lot of blindness, and further increases the investment risk.For the global consideration and avoiding repetitive construction and investment and taking into account the technical feasibility, this paper from the theoretical analysis and combining with the needs of practical application, especially researches the network model for planning and construction and planning procedures. In this paper, it shows the theoretical model of broadband access network and base stations access network and makes a simulation based on the theoretical model.Description the planning goals of local basic transport network planning procedures and further the general planning principles of convergence room, cable network and pipeline network on the basis of planning objectives.The paper shows the overall process of basic network planning and the detail planning presentation and output processes based on the theoretical model, planning principles and the content of planning process of the local transmission network planning procedures. Lastly,it gives the output in the form of renderings.The study in this paper forms the preliminary network models and network protocols, which makes a solid theoretical foundation for follow-up enhancing normative, reliability, economy of transmission network planning.
