Abstract: The research on mobile video Quality of Experience （QoE） is becoming increasingly important, but the existing QoE evaluation models lack the appropriate quantitative methodology. Considering the characteristics of mobile video services, a two-level weighting QoE quantitative evaluation model has been proposed in this paper. The proposed QoE model is made up of six kinds of influence levels according to their first-level weights；further, each influence level consists of multiple influence factors. In addition to packet loss and jitter factors, other influence factors have their second-level weights. This paper utilizes the Analytic Hierarchy Process （AHP） method to calculate all first-level weights, and then calculate most of second-level weights in addition to packet loss and jitter factors. Since packet loss and jitter are inter-dependent, it is unable to directly calculate their weights. Therefore, this paper finds their function f（packet loss, jitter） by network simulation experiments, and thus obtains a complete QoE quantitative evaluation model. By the QoE score testing, the proposed QoE quantitative evaluation model achieves a high precision, which proves the reliability of this methodology.
