CDMA system optimization program duration of continuation

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.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 CDMA network is analyzed and researched.After that optimized schemes for this problem are proposed and executed so that access time is reduced significantly.
