Study On The Evolution Of NGN Technology And Anhui Telecom Hefei Region Softswitch Network Optimization Design

In today’s society, informatization is in progress, the information network has been fully integrated into people’s real life. In the process of historical development, the communication network has undergone great changes. From the early simple voice telephone network, the integrated network includes voice, data and multimedia now. The development of network technology changes the information development in the world.The Next Generation communication Network-NGN, brought historic change to communication network. When softswitch-based NGN has been widely used, IMS technology is mature, which promotes the evolution of NGN network.With the development of the network, Network service operators have been restructuring and modification. Today, the number of users grows exponentially, user demand expands ceaselessly. If the operators want to seek a breakthrough, they must optimize network.Based on the above background, this paper introduces the NGN technology theory, studies the development direction of NGN, and puts forward the future evolution of IMS assumption. I think about the operators demand, in-depth study and optimization design of Anhui Telecom Hefei region existing network.
