Technology Choice And Networking Mode Of Shaanxi Mobile Local Transmission Network Under The Development Of The Whole Business

Accompanied by a high-speed ahead of the national economy, continue to increase the pace of reform and opening up, mobile IT levels continue to rise, the use of communications services to promote open gradually, the telecommunications industry, which has become increasingly fierce competition in Japan. Competition in the telecommunications industry to strengthen prompted operators are increasingly concerned about the idea of building services, from the previous construction of the network into a building, optimization, management together, the purpose is to allow the network resources more efficiently run network optimization gradually becomes a core part of the work. Especially in recent years, the progressive development of optical communications worldwide to develop inside the core business of optical communications market continues to stabilize at 10% growth rate. In the construction of new transmission network deployment time, the greatest extent of the use of resources already have to improve and expand the current network optimization, which is to save unnecessary investment, but also can play a role in the construction of the network; for Network optimization is gradually become a part of the network inside the building.Through these years the local transport network construction, the number of nodes in the transmission network in the fast increase in group net situation is very complex, with a variety of security risks, a great need for change and improvement. Currently, how to make improvements for the local transport network and change has gradually become a few large operators are more concerned about the issue. For local optical transmission network construction can be divided into:core layer, convergence layer and access layer. The core layer is between the role of master of business scheduling, the convergence layer of small particles business role is to organize and gather effect, the access layer is the variety of user access to the network. For this article, Shaanxi local optical transmission network conditions to start all levels in detail, used in the current network structure and expand the role of the two aspects of the network as well as to explain the problem has currently expanded deeper the study.This article is analyzed on the basis of the local transport network Shaanxi Mobile on the current status quo, for the problems and shortcomings of current local transmission network expansion encountered deeper investigation and research, while according to OTN and PTN related definitions, reference to the future development of the business and 3G,4G network construction give some reasonable suggestions for improvement network available---Join OTN technology used to create the backbone level, the core layer, convergence layer and access layer comprehensive experimental PTN technology, the transmission network to launch a new deployment, network architecture by these means to convert to a more scientific division in accordance with a comprehensive core business area layer, the backbone layer, the convergence layer and access layer of the four dimensions.
