From Quality of Experience to Willingness to Pay for Interconnection Service Quality

“…1 https://www.ict-etics.eu/ QoS differentiation mechanisms to customer demands, i.e., Quality of Experience, have been insufficiently satisfied by the available technical solutions, which have lead to the debatable success of network QoS so far [2]. This is further hampered by the diverse definitions and models available for QoE which have rather focused on integrating the user's perspective in the overall network environment [3,4,5,6,7,8] or quantifying the relationship between audio and video qualities and QoE [7,9,10]. However, these works have often failed to link the economic aspects in the users perceptions to concrete terms like the willingness to pay for certain QoS levels.…”

A Correlation Model of Mixed Service Qoe and Qos in Integration Network Environment

“…The all definition of QoE showed that QoE is standing on a higher level than the narrow QoS concept, if you want to get better QoE, you must provide a good QoS. Therefore, in a sense, QoE can be regarded as an extension and expansion of QoS narrow definition on terminal user perspective [6]. The relationship between QoE and QoS can be depicted as Figure 1, QoE is defined at the user level, the user is actually feel QoS, and QoS is closely related with application layer and the transport/network layer, from the user and the service level, QoS is a kind of demand, in order to meet this demand, the network layer adopts corresponding mechanism.…”

State-of-the-Practice in Evaluation of Quality of Experience in Real-Life Environments

“…This is why we first start by providing a short background of QoE concept. In 2006 Lopez et al defined QoE as "an extension of the traditional QoS in the sense that QoE provides information about the delivered service from an end-user point of view" [18]. Soldani et al in [19] stated that "QoE is how a user perceives the usability of a service when in use -how satisfied he/she is with a service in terms of, e.g., usability, accessibility, retainability and integrity."…”
