Research Of GPRS/EGPRS Network Optimization

GPRS (General Packet Radio Services) is an extension to GSM system, which can greatly improve bitrate on wirless.EGPRS (Enhanced GPRS) changes modulation and gives greater bitrate.The more subscribers using data service,the better quality of service they need,which quires the operaters to innovation on multi-function and multi-layer platform on network structure.GPRS Netowrk Optimization must be carried on as soon as possible.Since Heilongjiang China Mobile has applied EGPR technology in 2007,data service optimazion brings great challenge to engineers.Because of lack of GPRS/EGPRS kpi evaluation system, engineers get GPRS network qulity by 10086 custom complaints,or DT test periodicly,but hardly can get general network problems.On the other hand,the problem solving efficiency is low for no regulation on dealing with data service solutions.To avoid above-mentioned problems,and provide better data service,engineers start research on GPRS/EGPRS network optimization.The paper provides PDCH configuration, PCU capacity evalution, wireless parameter configuration, power control method, EGPRS new radio features on network capacity, interference and mobility, gives GPRS/EGPRS network kpi envaluation system,summarizes data service optimization methods and regulations.Besides,the methods give great results on applying on network.Th research on GPRS/EGPRS not only enhances the network ability on bearing and supplies quality of data service,but also improve self-optimazion ability on which the company cuts off millions on optimization expense.The research gives important guidance on GPRS/EGPRS network optimization.
