Overview
Radio network optimization (RNO) is the important step innetwork construction. RNO adjust the planning and designreasonably , improve the network coverage, increase thenetwork capacity, improve the network service quality andresource utilization ratio. Make the network operation morestably , and provide excellent service.
Data collection is the necessary premise of analysis andadjustment. Optimization data including:Driving test data(DT),Call quality test data(CQT),OMC performancedata, Customer’s complains, Alarm data , signaling dataand other data.
ZXPOS CNT ( UMTS Edition, Short for CNT) is theprofessional network optimization test software developedby ZTE . CNT helps the RNO engineer to do the test andanalysis. Locate network problem and evaluate networkquality and capacity, constitute the optimization solution.
