Networking Design And Test Analysis Of LTE Service Carrying Network

With the wide application and increasing maturity of 4G network technology,the development of LTE(long term evolution)mobile network technology has entered a stage of rapid development,and the service bearer network has also posed more stringent requirements for LTE technology.But,LTE technology and service development is mainly oriented towards the mobilization of the internet,and meanwhile,with the rapid growth of flow and data,traditional networks have also encountered some bottlenecks,such as the problem with the bearing capacity of metropolitan area network,and the changes in demand resulting from the accelerated market development have also promoted the growth of service market demand and the rapid evolution of data services.The development of time division long term evolution(TD-LTE)has become a major trend.In addition,the rapid development 4G mobile communication technology has brought about more obvious advantages in the type of users' wide-band access,and the specification of carrier technology has also shown new trends and requirements.Therefore,how to enable PTN(packet transport network)to fully bear LTE services has become a main research direction for the development of PTN technology.Under this background,the construction of PTN as the LTE services mobile bearer network has been carried out in various regions of China.In this paper,the author's main work and research achievements were illustrated from the following perspectives: firstly,the background and significance of the research into PTN-based LTE bearer network were introduced,the current status of domestic and foreign researches on LTE wireless network technology was analyzed,and development of LTE-related technologies and critical PTN technologies was studied intensively.Secondly,the bottlenecks of bearer network can be solved through LTE,its high bandwidth and flexibility can satisfy the main technical demands at present,and it can also greatly reduce the time delay during data processing,which poses more stringent requirements for the transmission bearer network.In this paper,the bearer network LTE wireless network services,communication principle,LTE network structure,networking scheme,and the structure of LTE bearer network and the way how the traffic forwarding mechanism were mainly studied and designed.Finally,the demands of the main services of LTE bearer network for adaptability to network speed were verified through the design and analysis of real cases based on the application of PTN devices in real wireless network construction,and the solution to increasing LTE network speed was given.Through the design and analysis of PTN bearer network for LTE service networking,this paper provides certain theoretical and practical references for mobile networking technology.
