Abstract

Measuring the impact of technical variables, such as latency, bandwidth, or resources priority-access, on the Quality-of-Experience (QoE) of various services, demands an extensive feedback from end-users when those variables change. Estimating the QoE in a given scenario becomes harder, when non-technical variables, such as price, need to be considered in addition to technical ones. In any case, detailed feedback that correlates all variables that may affect QoE is needed by end-users for each service separately. In this work a deterministic mathematical model (DQX) encapsulating user demands, service characteristics, and variable specifications is proposed to formalize the QoE calculation, considering one or multiple and diverse variables. The output of QoE functions presented here can be normalized easily so results will be compatible with the five-point scale Mean Opinion Score (MOS), proposed by the ITU-T.
