基于QoS量化用户体验质量的评价模型

针对网络环境中业务供应商提供的业务不能很好的满足用户需求的问题，引入用户体验质量（QoE）并结合服务质量（QoS）参数，通过仿真网络得到相应数据，使用matlab工具分别建立用户体验质量与比特率、用户体验质量与丢包率的评价模型.运用统计分析方法对评价模型进行数据分析，并与史蒂文斯幂定律、韦伯-费希纳定律等模型进行对比验证.结果表明，构建的评价模型能更精确的体现用户体验质量与服务质量的关系，为供应商提供了重要的参考依据，并指明了服务方向.

Evaluation Model of Quantitative QoE Based on QoS

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.
