Research on Planning of No.7 Signaling Network

Running quality of telecommunications network is directly affected by configurations of No.7 signaling network. Upon the base of the structure of No.7 signaling network,the paper analyzes the factors that influence the quantity of hierarchy of leveled signaling network, and illustrates confined relations of the factors. The methods of connection in No.7 signaling network is discussed later. By these above analyses,it draws some preliminary conclusions on the planning of No.7 signaling network. Finally the text summarizes No.7 signaling network in China.
