5G正在迅速从愿景走向现实，对于5G的技术要求已经达成一些共识。传统上，基于现有标准的绩效监控一直侧重于技术关键绩效指标（KPI）。然而，实际上更重要的是直接关注体验质量（QoE）。 5G 中的服务交付应考虑到现有和新兴用例的多样性以及每种服务类型的广泛需求。这些要求只能通过从以系统为中心的架构转变为以用户为中心的架构来解决。鉴于此背景，本文旨在推动将 QoE 要求纳入 5G 生态系统，并强调以最终用户为中心的网络设计的重要性。为此，我们确定并分析了可以塑造以 QoE 为中心的网络的基本必备属性，并讨论它们如何适应 5G 大局。然后，我们描述 5G 中 QoE 的当前和新兴技术推动因素，以及实现这一目标的重要挑战。
5G is rapidly moving from vision to reality and there is already some consensus regarding the technical requirements of 5G. Traditionally, performance monitoring based on existing standards has been focusing on technical Key Performance Indicators (KPIs). However, it is actually more important to focus on Quality of Experience (QoE) directly. Service delivery in 5G should account for the sheer diversity of existing and emerging use cases as well as for the vast variety of demands per service type. These requirements would only be addressed by a shift from system-centric to user-centric architectures. Given this background, this paper aims to push towards integrating QoE requirements in the 5G ecosystem, and to highlight the importance of network designs that have the enduser at their epicenter. To this end, we identify and analyze the essential must-have attributes that can shape QoE-centric networks and discuss how they fit in the 5G big picture. Then we describe current and emerging technological enablers of QoE in 5G, as well as important challenges towards achieving this goal.
