The LTE Network Based On IPRAN

With the development of LTE services,it is difficult to satisfy the service requirements in the traditional SDH-based transmission network.Compared to 3G,LTE bandwidth requirements are higher than 3G and network delay is lower.In terms of network structure,the IP address setting and the IP routing protocol interworking are needed between 4G base stations,and between the base station and the core network.The network structure is mostly ring type and chain type,and the aggregation node is reduced.Nowadays,3G bearer network has partially adopted PTN equipment to meet IP requirements,and 4G network mostly adopts IPRAN equipment.However,in the initial stage of base station construction,due to various factors such as construction cost,optical cable routing,and room distribution,the connections between base stations,between base stations and uplink equipment,and between the entire wireless network and the core network,cannot be well met in the era of increasing mobile data volume in terms of bandwidth and delay.IPRAN's network structure wins the favor of most telecom operators with its IP-based networking and easy-to-flat network structure.Based on the research of IPRAN networking characteristics,this paper introduces the specific implementation scheme of the subsequent construction of LTE base station in Yinchuan City,and gives the design and implementation scheme of the bearer network based on IPRAN equipment.The specific content mainly includes the base station access and daily troubleshooting.
