Design And Application Of Bearer Network Based On IP RAN Technology

With the continuous development of mobile communication technology,all kinds of new services put forward higher requirements for communication networks,especially bearer networks.As the basis of the whole communication network,bearer network bears the high-speed growth of mobile network traffic,and its network quality directly affects business performance and customer perception.In view of the rapid development and evolution of mobile networks,different service networks show a trend of integration.In order to comply with this trend,the research of bearer networks is mainly embodied in three aspects: large capacity,grouping and intelligence.At present,the carrier network mainly adopts IP RAN packet technology,mainly for the return of 4G wireless base station service to EPC core network.It has many disadvantages,such as low equipment configuration,large network hidden dangers and disorderly site access.It is difficult to meet the needs of the 5th generation mobile communication(hereinafter referred to as 5G)with large bandwidth and low delay.The purpose of this paper is to study the design and application of bearer network with IP RAN as the main body,optical cable and DWDM cooperation.Based on the current situation,the future service output bearer network scheme is oriented to ensure that the business needs are met,so as to make the later project construction more targeted and controllable,effectively reduce the construction risk and cost,and ensure the smooth implementation of 5G bearer network construction.The main contents of this paper are as follows:1)Network bandwidth configuration.According to 5G low-frequency and high-frequency business attributes,the demand of bearer network is analyzed,and the bandwidth allocation of 5G bearer network access,convergence and core levels is deduced from bottom to top.2)The analysis method of key points in the design of output bearing network provides support for the smooth implementation of the project.Build the coverage model of DU computer room,output the optimal coverage radius under different station density,reduce the overall construction cost under 5G intensive networking scenario;Based on the analysis of large dataPrediction promotes the construction or expansion of 5G bearer network to be more targeted and predictable,improves capacity and saves investment;relay distance analysis is based on equipment,optical cable and other optical path parameters,so as to ensure the timely and optimal opening of 5G services in the design stage.3)IP RAN design and professional collaboration.Output IP RAN network structure,networking mode,service configuration and other design schemes;For the 5G stage of ultra-dense networking and ultra-low delay characteristics,output IP RAN as the main body,optical cable,DWDM professional collaborative construction design.4)Collect and analyze the implementation plan of the data output project of the existing network.According to the current situation of a city's carrying network,collect data,and analyze the data of network traffic,bandwidth utilization,ring rate and so on,output multi-dimensional scheme from bottom to top.Combination of Access Layer Upgrade and Ring Disassembly.The main structure of IP RAN+OTN is formed by introducing large capacity equipment into the convergence ring,and the core layer carries the export flow of the city,focusing on the orderly completion of expansion or new construction ahead of schedule based on traffic forecasting analysis.
