摘要

Offering the subscriber with good satisfaction is the ultimate target of a service provider, since the user's satisfaction is necessary if the service can achieve success. Thus it is of great importance to know how users have perceived the quality of service. QoE (Quality of Experience) is a "new" terminology introduced to describe this user's perception. It reflects how satisfied/dissatisfied the end users are with a certain service and represents how well the service fulfills the user's expectations. Although it has already been near a decade since the introduction of the concept of QoE at the beginning of this century, a comprehensive introduction and detailed explanation of it and the related issues are still absent. Additionally, the usage of different terminologies as well as the varying explanations of QoE may obscure the concept to new researchers and readers. In this paper, we provide a systematic survey of QoE related issues. We review of the introduction of the QoE concept and the correspondent terms by differ communities. We compare and discuss its relationship with another concept, QoS, which is also used for service quality description. Moreover, the technical issues related to this subjective concept — the QoE measurement as well as the QoE-based QoS engineering, are introduced.
