Cdma Mobile Networks Continue When The Optimization Study

With the access to the WTO organization, CDMA systems come into China, operators face unprecedented competition with each other. Under the requirements of network improvements by the users, the quality of network dominates the fate and development of mobile operators. Network optimization has become a major job for mobile communication operators. At present, operators mainly concern about how to improve the network utilization rates by optimizing to dig the maximum potential of present network.The objective of network optimization is to improve the quality and utilization of the network. The network quality is the result of the interaction of many factors. With depth development of optimization, the job of network optimization has extended from purely network maintenance to all sections including marketing, network planning and engineering, which are considered throughout mobile network operating.In this paper, a deep study of the principle of the CDMA system is presented first. Then the prominent problem of overlong access time which is currently reflected in existing Chengdu Unicom CDMA network is analyzed and researched. After that optimized schemes for this problem are proposed and executed so that access time is reduced significantly. Further research as user behavior and user development trends is studied in this article also to give reasonable suggestions for later network plan and engineering.
