Chengdu Telecom Ngn Network Planning And Design

NGN is the communications industry concerns and to explore a hot topic of discussion, network operator, apparatus manufacturers and ITU, IETF and numerous technological forums are all paying close attention to NGN, propose, to NGN network imagination of development, describe existing traditional PSTN network to NGN network gradual progress course from different angle each one after another.This thesis is exactly directed against problem described above, regard telecommunication PSTN network current situation in Chengdu as the main research object, analysis depth on the basis of exchanging the apparatus commercial and which tests the platform softly, development make innovative and exploration study, plan, design to Chengdu telecommunication the near future NGN network. The main content is:1. Have summed up and introduced the project background to NGN network gradual progress programming and design of the telecommunication PSTN networks of Chengdu partly, thesis subject involves the range, the basis of programming and design, and the goal of NGN network development of the near future.2. Through studying NGN technology network operators, apparatus manufacturers' development and application case at home and abroad, through being domestic, NGN succeed case and mode in the world, prove NGN in Chengdu communication network practical application and feasibility that develop; Study domestic and international NGN current situation of the development at the same time, do the first step of key in " telecommunication NGN network programming and design in Chengdu "s well too.3. Chengdu NGN network develops programming and design in order to do well, must study and analyze the communication network current situation of Chengdu and there are problems first. This chapter expounds the fact network business and network develop the existing problem now in Chengdu in detail, so as, prove the soft commutation substitute, remit necessity to answer office.4. Describe NGN network group network scheme and construction principle in detail, involve content have Soft core exchange network and access network group network principle, have now PSTN network to NGN network implementing scheme of gradual progress, gradual progress scheme, office of pass, TG talk to remit, connect way is soft to exchange SHLR and existing FHLR relation, SHLR and air shower HLR relation affair, exchange the business and intellectual net business relations softly.5. Describe NGN network programming in detail, involve the Softswitch equipments, Trunking Madia Gateway, Access Network and Signaling Gateway. The Signaling Network, the Traffic network structure and the resources of Softswitch programming person who plan issue, make the transition with communication network at the same time, charge, business manage, operate, maintain, support system need, make corresponding adjustment and redesign too.
