Model-Based Approach to Measuring Quality of Experience

Quantifiable quality measures are necessary for VoIP service providers in order to offer services and be sure to keep users for their services. Existing methods used for evaluating the Quality of Experience (QoE) mostly rely on user survey and scores from the user, which are too subjective and need much processing time and cost. This paper proposes a pentagram model for measuring QoE. The model consists of five factors, including integrality, retainability, availability, usability, and instantaneousness. The experiments show that the proposed model offers better performance in terms of quality measurement than the conventional method.
