A wavelet network assessment model for Customers´ Satisfaction Degree of 3G network

With the large-scale 3G network application and market competition intensifies, operators pay attention to the Quality of Experience (QoE) increasingly. The main research results are how to map Key Performance Indicators (KPIs), Key Quality Indicators (KQIs) and Quality of Service (QoS) to QoE. The Customers´ Satisfaction Degree (CSD) indexes contain technological and non-technological aspects, which are not fully contained in QoE. This article builds a wavelet network assessment model of CSD of 3G network for the first time, including technical factors, operating factors, man-machine interface factors, user expectations factors, price factors, service ability factors. These factors are composed of 16 important parameters. The experiment proves that the result of this model could satisfy the precision requirement.
