Research Of CDMA2000Mobile Communication Network Optimization Strategies

Network optimization is through the acquisition of the system operating parameterand data analysis, mining the reasons of influence network quality, and to explore thecorresponding technical means or parameter adjustment strategy to achieve systemoptimum operation, to maximize the economic benefit and social benefit.As one of the3G mainstream technical standard, the cdma2000mobile communication system is aninterference limited communication system, the system capacity is the soft capacity,network optimization, not only can increase system capacity, but also to improvenetwork performance and quality of service. For CDMA2000mobile communicationssystem network optimization related technology research and engineering verification,intended to explore its optimization strategy from the two aspects of voice optimize anddata optimize, and to verify the feasibility and effectiveness of the optimization strategyby examples. The papers do research work and research achievements include:①To induce and summarize the network structure of the CDMA2000system,code resources, signaling processes and system messages, and spectrum allocation,parameter configuration, planning processes, channel configuration, power control,switch control and load control network planning connotations. To provide applicationobject for network optimization, and lay the technological foundation.②In the CDMA2000system operation, environmental change, user growth,business diversity support, will cause the coverage of the network part regionalvariation, performance degradation. Focuses on the CDMA2000network optimizationtasks, processes and measures. In voice optimization, separately from the pagingoptimization, pilot pollution, cover optimization, capacity optimization, neighborhoodoptimization, interference analysis to dropped calls analysis, to analysis of the causes ofthe problems, and make optimization strategy; in the packet domain optimization, inorder to DO network and1X network different optimization emphasis as the foundation,determine the optimization principle, and make the optimization process.③Combined with the Transportation of CDMA2000system optimizationengineering, research PN confusion optimization, pilot pollution optimization andregional optimization, validate and assess the effectiveness and feasibility of theimplementary optimization strategy.
