In view of the problem that service from provider cannot meet the needs of the users in the network environment, this paper introduces the Quality of Experience (QoE) and Quality of Service (QoS) parameters. Through simulation network, the corresponding data are obtained. And two evaluation models (QoE with bit rate and QoE with packet loss rate) are established by using MATLAB tools. Analyzing the data of evaluation models with statistical analysis method, the model is verified by comparing with Stevens' Power Law model and Weber-Fechner Law model. The result shows that the evaluation models can precisely express the relationship between QoE and QoS, and it can provide the direction of service and an important reference for the service providers.
