Analysis And Research On PTN Structure Optimization And Index System Of Changsha Mobile MAN

At present,LTE has been a large-scale construction,so the entire mobile network has also put forward new requirements for the transmission network,the most important performance in the bandwidth requirements of the steep,such as conditions permit,an eNodeB site must ring,After the loop is over 6 NEs,it is necessary to upgrade GE to 10GE.At the same time,the transmission network is limited due to transmission hidden dangers(long single-link,super-large nodes,etc.),so it is very important to optimize the transmission network.PTN as the current LTE mainstream bearer technology,can help LTE to achieve true wireless broadband and wireless Internet,which led by China's 4G standard TD-LTE network currently has 14 operators around the world.Bearer network as the basis of the telecommunications network,its planning and construction should be preceded by the development of the telecommunications business network in order to effectively support the business network development and evolution.Therefore,the evolution of bearer network for LTE becomes important and urgent.PTN as a fusion of transmission and packet technology,more and more attention by operators and large-scale deployment,PTN MAN optimization is not only reflected in the operation of the existing network optimization and improvement of the quality,but also to run through In the early stages of the construction of the mobile network program,the project implementation stage,the trial operation phase of the project,the late opening of new business development programs,network adjustment programs such as the development of each link.In this paper,by combining Changsha Mobile 2015 transmission network optimization project,the hidden dangers of mobile PTN metro in Changsha are analyzed and corresponding optimization methods are given.At the same time,a set of scientific,feasible and efficient PTN MAN security quality evaluation index System,and the index system of Changsha Mobile under the jurisdiction of the seven districts and counties PTN MAN metropolitan area network were analyzed and compared in order to supervise and lead the various districts and counties to optimize the transmission and construction of specific issues,so that Changsha Mobile PTN MAN Construction,optimization,maintenance to meet the needs of LTE construction.Prior to the planning,design and construction issues,resulting in the current network transmission capacity is insufficient,and in order to cope with the future of LTE and other business needs,to deal with the current network problem,the future needs of a reasonable analysis and forecast,this paper For LTE network planning,the author puts forward some suggestions on the planning and optimization of PTN in LTE application.
