Study On The LTE And Full-service Solution Scheme

With the restructuring of the three major telecom operators,Mobile,Telecom and Unicom,the superior status of Mobile has been challenged.Each of the three telecom operators has its own advantages.Especially for the 4G full-service operation,each operator directly launched the full competition.In the face of such a competitive pattern,whether China Mobile transmission network could cope with large flow and large bandwidth coming from LTE and full-service carrying network,upgrade smoothly from the existing network structure,response rapidly to the future network development needs,own a good cost performance or not,it is an urgent issue for China Mobile transmission network.Compared with 2G and 3G networks,LTE has comprehensive data,large bandwidth and small delay characteristics.With the commercial development of LTE,the users' demand would also increase.As the basic network,whether it is architecture change or network capacity upgrade,transmission network are based on demand-driven business.Either from the network capacity,network security or network covers,LTE networks put forward new requirements to our transmission network.Facing to these needs,huge business,the rapid expansion of the network size,and many other challenges and pressures,it would give detail analysis to transmission network infrastructure and service carrying schemes.Starting with the basic issues of LTE and existing network architecture,this paper analyzes the development status of the transmission network and points out the existing problems of the network,and introduces the LTE full-service scheme.The main contents of this thesis are as follows:(1)It analyzes the current situation and problems of existing transmission networks and puts forward the construction demand for the evolution and deployment of LTE and the full-service carrying network,and provides an important basis for the construction of the new urban transmission network.(2)Based on the analysis of existing network problems and LTE service needs,the network structure and carrying scheme of new metro transmission network are obtained.At the same time,the construction idea of metro network is discussed comprehensively.(3)Analyzing the different service types and combining to the actual construction cases,it puts forward the solutions of 2G voice business,4G data service,important group customer service and broadband internet service.(4)Combining to the actual construction cases,it provides a complete set of plans and schemes for LTE and full-service,by analyzing the current situation of the network,pointing out the existing problems and challenges.
