CDMA Wireless Network Optimization Of Ningxia

The mobile communication relates to our social development and everyone’s daily life,andthe requirements of the network’s qualityare higher and higher with the increasing importance ofthe mobile communication,so the research of network optimization becomes a key issue paidattention by each mobile communication operator.With the adoption of rapid and effectivenetwork optimization method,it is one of the main concerns of mobile operators to improvenetwork performance and service quality.Because CDMA is the interference-limitedsystem,optimization of CDMA network becomes very important.This paper not only introduced the development history of CDMA and the significance ofresearch,but introduced the key techniques of wireless net of CDMA IS-95、CDMA2000.At thesame time,we also research the optimization methods、optimization process.Based on this,wehave studied the analysis methods in network error of CDMA wireless networkoptimization,summarized to the experience of it. Including the analysis of lose word, thepollution of guide frequency, and the cover optimization,and so on. Based on the analysis ofCDMA20001x/EV-DO network of CHINA TELECOM Ningxia branch, optimize CDMA voiceservice and data service of the network.Concretely, methods of optimizing are as such asdropped calls problem、pilot pollution issues signal interference issues、call setup timeissues.We give the several examples of optimization project,from the malfunction description tomalfunction orientation,and optimization scheme.In summary,the research of it will have realisticsignificance for network optimization,the advance of network environment,and also thepromotion quality of running network.
