Methodology to specify QoE degradation factors for mobile applications

Abstract

While using applications on mobile terminals, user quality of experience (QoE) often degrades. There are two methods for QoE improvement, carrier actions and user actions. We focus on the latter, which requires less time and money for improving QoE than the former. Efficient actions for improving QoE differ by user because each user may be in a different environment. We propose a methodology for specifying QoE degradation factors in order to suggest appropriate user actions. With our methodology, we collect the logs of many users and specify QoE degradation factors by referring to high QoE users.
