QoE Evaluation Method through Logistic Regression Model Considering QoS Tolerance

As the evaluation of quality of experience (QoE) is an ordinal multiple categories problem, the logistic regression model could be used to evaluate QoE. The regression model of QoE categories probability distribution is established based on the logistic regression model. This model relates cumulative probabilities of particular QoE categories to quality of service (QoS) parameters of network. Considering the tolerance of QoS parameters, a QoE evaluation method through QoE categories probability distribution regression model is proposed. This method eliminates the compensations among QoS parameters. It yields the category of QoE while giving a probability of each possible category. Finally, the QoE of Web service is estimated utilizing the proposed method and the result proves the method to be comprehensive and exact.
