摘要
This study contributes towards the relatively new but growing discipline of QoE management in content delivery systems. The study focuses on the development of a QoE-based management framework for the construction of QoE models for different types of multimedia contents delivered onto three typical mobile terminals—a mobile phone, PDA and a laptop. A statistical modelling technique is employed which, correlates QoS parameters with estimates of QoE perceptions. These correlations were found to be dependent on terminals and multimedia content types. The application of the framework and prediction models in QoE management strategies are demonstrated using examples. We find that significant resource savings can be achieved with our approach by contrast to conventional QoS solutions.
