Study And Design On TD-LTE Mobile Bearer Network In Fuzhou

Along with implementation of "Broadband China" strategy and full coverage of TD-LTE wireless network,the data services have been replaced voice services and became core business for mobile communication network of China Mobile,the rapid growth of which brings significant challenge to the service-bearing communication network,thus calling for strong capacity in bandwidth expansion,mature networking capability,end-to-end protection mechanism for services and highly efficient and flexible scheduling capacity from bearer network.OTN and PTN technologies bring a solution to a set of problems confronting China Mobile when dealing with multiple services and high bandwidth concerning aspects like unified bearing,feeble OAM management,strict quality of service,security and flexibility in networking,which consequently makes them main bearing technologies in the realm of TD-LTE communication network.To start with requirements over bearer network of TD-LTE network,taking mobile bearer network in Fuzhou as an example,a study is carried out focusing on the characteristics,applications and planning requirements of mainstream technologies of bearer network with analyses of bandwidth requirements based on services as well as actual network problems,aiming to put our achievements in practice,in the planning and designing phases of the mobile bearer network in Fuzhou.Key points of our work are as follows:(1)Appropriate technologies of bearer network are made for China Mobile by virtue of related technology specifications.(2)Planning objectives and planning schemes are brought forward with reference to the current situation,existing issues and analyses on business demands of mobile bearer network in Fuzhou,incorporating network planning,wave length assignment,planning of protection mechanism on OTN level and bandwidth planning,networking planning,planning of protection mechanism,QoS configuration,etc..on PTN level.(3)According to business expansion tendency and intelligent network development and study on mobile bearer network in the medium and long term in Fuzhou,integrating biplane network construction so as to secure sustainable network development with introduction of SDN technology in time,thereby enhancing network redundancy capacity.(4)To design for the planning of bearing network of the Fuzhou Mobile Company,it includes network design,main equipment selection,channel organization,service protection,QoS deployment,supporting resources construction scheme,etc,and make well the investment estimation;at the same time,network construction shall be implemented,and focusing on equipment installation,opening,data configuration and other related matters for a major new site.(5)Analyses on major operating indices following completion of website construction are conducted as well as performance tests,during which major malfunctions are fixed,verifying the effectiveness of the project at last.The research in this thesis lays a sound foundation for the development and construction of mobile bearer network in Fuzhou,accompanied by reinforced scalability and safety of network development,efficient utilization of resources and advanced service scheduling capability.The study and design can be used for reference in ensuing construction and maintenance of mobile bearer network in Fuzhou or bearer network construction in other cities as well.
