The Research And Application Of IP RAN Network

As China’s telecommunications industry restructuring and3G and4G licences issued, all operators deploy their VOIP,3G/HSPA+and LTE mobile broadband business accordingly. The traditional transmission network technology has not satisfied with the development needs of existing business. In view of the grouping service statistical multiplexing transmission and the sudden flow, Packet Transmission Network makes related design, which of Group business as the core and support circuit of traditional business. The network technology can better support business load more, and have strict QoS, the reliability of the telecommunication level, strong network scalability, and other functions in order to satisfy with all kinds of business demand for hosted network.This paper first introduces the present situation of packet transport network technology at home and abroad and makes some comparison with PTN and IPRAN, the two implementation schemes for packet transmission technology. Also according to the analysis for the present situation of the three main operators, grouping network concrete is to use the grouping of PTN network implementation plan or IPRAN grouping network was adopted to realize more reasonable.This paper focuses on the implementation scheme of IPRAN group technology, And the network model of the IPRAN are analyzed at the same time combining the IPRAN technical characteristic which gives the optimal and suboptimal and the not-recommended network structure。 This article also depends on the various bearing business putting forward the corresponding business hosting plan. Zte IPRAN equipment has been introduced in the practical application of Jiangsu Unicom group network construction and the corresponding IPRAN network test, which prove that the IPRAN network can satisfy with the various business of Jiangsu Unicom bearing requirements. IPRAN network scheme in this paper provides the reference for the IP bearing network being built by all operators.
