IP RAN And In Yancheng Unicom Access Network Application

Mobile communication network to HSPA/LTE evolution is the inevitable trend, As users of mobile data service development, Network bearing will be massive IP business and a small amount of TDM business, Mobile data traffic and bandwidth demand increasing by geometric series, Either the operator or equipment manufacturers, Are working on the next generation of mobile transmission network configuration and deployment method. Radio access network IP and broadband, To satisfy both the traditional base station service point-to-point static pipeline deployment requirements, also support the sharing, dynamic deployment needs. According to the unified deploy according to group company of Yancheng Unicom positive input to the IP RAN program development, planning and Implementation, In this paper, the source material to the project.The paper firstly introduces the present IP RAN access network development background, technical characteristics, And a detailed comparison of the realization of the principle of PTN, key technology, comparative advantage and interworking ways.The paper is focused on analysis of IP RAN in access application, by the Huawei IP RAN device (ATN+CX) as an example, List of the IP RAN bearing typical access business scene, principle and main function design, Proposed by IGP, MPLS, BFD, VPN tunnel network planning design principle, Develop QOS mechanism, synchronization mechanism and OAM design; According to the needs of communication service and the IP RAN service application scenarios and design principles, based on the original access network of Yancheng Unicom paper puts forward Yancheng Unicom packet transmission network plan and implement.Finally the paper summarizes the related technical characteristics and IP RAN in the future comprehensive carrying network application, Once again expounded IP RAN access network is to realize the communication network architecture is an important choice.
