Telecom operators have recently faced the need for a radical shift from technical quality requirements to customer experience guarantees. This trend has emerged due to the constantly increasing amount of mobile devices and applications and the explosion of overall traffic demand, forming a new era: “the rise of the consumer”. New terms have been coined in order to quantify, manage, and improve the experienced user quality, with QoE being the most dominant one. However, QoE has always been an… Expand
