Towards assigning value to multimedia QOE

The development of multimedia services with a high level of acceptance has created the necessity of migrating from traditional concepts like quality of service (QoS) to the more user-centric concept of quality of experience (QoE), where service performance is assessed in terms of user-perceived quality. However, due to the specific nature of current laboratory tests, it is difficult to extrapolate the results obtained in the laboratory to the real world. In this document, we take up the initiative made by different authors to assess the ecosystem of multimedia services from an interdisciplinary perspective. In this paper, we present results of a series of studies conducted to analyze the overall perception of VoIP-based speech communication service quality from a user perspective. The aim is to link QoS-related technical characteristics of IP-based multimedia services with QoE not only in terms of lab-QoE, but in terms of the value users associate with it.
