User feedback oriented quality of experience management framework

Recently, Quality of Experience (QoE) has been introduced as a subjective measure of a user's experience of communication services. QoE was expected to take the place of traditional Quality of Service (QoS) measure in that QoE may express a direct and accurate user experience. In this paper, we propose a QoE management scheme which is based on a user's simple feedback. We explain the proposed QoE management steps and the dominant reason extraction algorithm to determine the quality-falling instance. We also present a QoE prediction method that will provide an optimal quality management scheme in communication services. Experiments on multimedia streaming service prove the efficiency of the dominant factor extraction algorithm, and the experiment using the QoE prediction method present a very high accuracy. The QoE management scheme proposed in this paper can be generally adapted to any communication services, to increase the efficiency and effectiveness of quality management systems.
