Jining Local Network Transformation And NGN Network Construction

The local PSTN network of Jining CNC set up in 1995, own a mature PSTN network through the construction development for more than ten years.to 2005, the local telephone capacity attains 2,300,000 lines, the voice sevice has composed entire main business ncome. Because With people rising demanding of telecommution and raise develop with telecommunication technically, existing network restricted development of new business on a certain degree. Today operators are experiencing technique transformation of telecoms since 2005. the convergence of PSTN and Ip becomes a trend . According to the network intellectualization construction and the NGN construction of the Jining CNC nearly two years,This article discuss way and method of local PSTN network transformation.The first chapter mainly introduces basic situation of the Jining local telephone network, point out existence question of this kind of network, as well as each kind of difficulty which is under the new service demand.The Second chapter mainly elaborates the Jining network intellectualization transformation process, analyze from network optimization train of thought, solution provider and telligent service realization in detail . the network transformation key point is The whole PSTN telephone traffic gathering to the TM exchange , the integrated data store introduction and the intelligentnetwork construction is the network transformation key point.The third and fourth chapter mainly analysis the demand for NGN networks, putting forward net NGN develop way of thinking, introduction NGN construction solution.The project includes a plan of network construction, soft exchange construction , trunk gataway construction, signaling gataway construction and IP carrier network construction.Chapter 5 discourses a few difficult problems in the NGN construction, the first one is place of soft exchange in the whole network, the second one is number plan of NGN telephone number , because of involving mixture of number plan, it needs to coordinate with intelligence sevice and 97 service supporting system.I have been being engaged in the network management of the local network and exchange maintenance ,and know well to the whole network condition. I have participated a great deal of engineer activity in the network the development the process.Especially in the engineering projectof the whole net intelligence and NGN construction, I participated in the network reformation plan,engineering construction and service test work.
