Planning And Application Of A Unicom Transmission Network Based On IPRAN

With the deployment of the "broadband China" strategy,the construction of the communication industry in China continues to create a new climax.Since 2015,the three major telecom operators have been pushing down the cost of telecommunications and upgrading the basic network.The development of wireless network and fixed network business for the performance of the transmission network puts forward the more strict requirements,so building a low cost,strong stability,high reliability and excellent integrated service bearing of transmission network is particularly important.The development of information industry requires operators to accelerate basic network transformation,so how to use transport resources,becomes the problem urgently to be solved in modern network construction.In such an environment,the IPRAN(IP Radio Access Network)network has been favored by major telecom operators.This thesis firstly introduces the history,development and current situation of IPRAN,and then introduces its related technologies.Next,the IPRAN is compared with the current mainstream network schemes,and the advantages of IPRAN network are proposed.Based on the background of a city unicom company,this thesis analyzes the current situation of the transmission network in the city and the county,and puts forward the construction plan of IPRAN.In the selection of equipment,the IPRAN equipment of huawei is selected.On the IPRAN structure,the core equipment is deployed in the core communication room.An aggregation device is deployed in the city node,and two aggregation devices are deployed in the county and county-level cities.The convergence device is connected with the core equipment to form a rectangular network and the core equipment is connected with the CE(Customer Edge)device according to the MESH.Optimizing the allocation of optical cable resources in the convergence layer,ensures the independence of IPRAN equipment.Finally,the network performance of IPRAN and the business protection capability of the whole network are tested.The reliability of IPRAN is verified.
