Research And Implementation Of Adaptive Measuring Tool For Mobile Video Services QoE

As the development and common use of wireless and mobile terminal,watching online video on mobile terminal becomes more and more popular,Quality of experience(QoE)directly affects the amount of users.It is an intense focus for network operators and content providers on how to simply and accurately evaluate QoE of mobile terminal,based on which optimize the network and improve service quality.This paper first describes techniques of mobile terminal services and defines QoE and its evaluation methods.Then evaluate the QoE of mobile video services from the perspectives of factors and evaluation technique research status.Influenced by network factors,application factors and user factors,it is hard to get accurate QoE data on mobile terminal,for which,this paper proposes an adaptive measurement based on Android mobile terminals streaming video services QoE.By measuring and evaluating QoE of online video service in real time,it can be more accurate and practical.First,an application that can automatically measure QoE of videos is designed to measure objective quality of service(QoS)parameters and map to the subjective QoE(MOS value)through a utility function.Then improve the theoretical model by studying the correlation between theoretical QoE assessment model and actual user feedback.Finally,based on correctional QoE evaluation model,a function of monitoring mobile network connection status is added on QoE evaluation module to improve measurement tool,which makes it possible to automatically switch evaluation model to measure QoE according to wireless network connection type.Thus evaluate QoE automatically adaptive to different network.
