The Planning And Design Of Evolution In The Data And PSTN Network Of Maanshan Unicom

Both the Maanshan Unicom and the Maanshan Netcom have a PSTN and data communication network . The two netwok have been running for many years and are not meet the needs of business development. In Anhui Province, the fixed telecommunications market is monopolized by China Telecom, with the restructuring of the telecommunications industry, how to use the least investments in the two existing network integration and evolution to meet the needs of the market Department and won the fierce market competition has become urgent problems of the new Unicom.The paper analysised the status of fixed network of the Maanshan Unicom, combined with the current network conditions and market demand, come up with the design of evolution to the NGN network and integration with the current network. In this paper, equipment selection of Softswitch platform, TMG, AG, SG and IP bearer network were described; the. capacity and number of boards of different equipment were calculated ;and the different routing algorithm of IP bearer network were compared and chosen.The study of the paper is as follows. The calculation of BHCA demand forthe Softswitch platform. The analysis and calculation of relationship in the circuit input rate and output packets rate (or bandwidth) of TG with a different way of coding rate. The analysis and calculation of relationship in the different link rate and output packets rate (or bandwidth) of SG. The comparison and analysis of comprehensive performance in the network.The summary of configuration method in VLAN.In this paper, local and remote Softswitch communications signaling routing and traffic routing, respectively, were analyzed. Also the long-distance traffic of TG on the local network, the TG circuit capacity, IP packet rate, as well as the bandwidth of AG were calculated and analyzed. The innovative point of this paper: the realization of the integrated VPN which combined the GSM and WCDMA mobile networks of Unicom with the fixed telephone network of Netcom . The innovative point enhanced the advantage of the New Unicom in the telecommunication markets, which achieve the goal of one-third of the world in the highly competitive telecommunications market.
