A Note on Quality of Experience (QoE) beyond Quality of Service (QoS) as the Baseline

In this work, a new approach to definition of quality of experience is presented. By considering the quality of service as the baseline, that portion of the QoE that can be inferred from the QoS is excluded, and then the rest of the QoE is in an incomplete way represented with the notion of QoE at a Boundary. With the QoEaaB as the core of the proposed approach, various potential boundaries, and their associated, unseen opportunities to improve the QoE are discussed. In particular, property, contract, SLA, and content are explored in terms of their boundaries and also their associated QoEaaB. With an interest in the video delivery use cases, the role of the user type is considered, especially for the perspective of the isolation experience associated with multi-tenant operations. It is concluded that the QoEaaB can bring a new perspective in QoE modeling and assessment toward a more enriched approach to improving the QoE based on innovation and deep connectivity with user.
