QoE Management for Future Networks

Abstract

This chapter discusses prospects of QoE management for future networks and applications. After motivating QoE management, it first provides an introduction to the concept by discussing its origins, key terms and giving an overview of the most relevant existing theoretical frameworks. Then, recent research on promising technical approaches to QoE-driven management that operate across different layers of the networking stack is discussed. Finally, the chapter provides conclusions and an outlook on the future of QoE management with a focus on those key enablers (including cooperation, business models and key technologies) that are essential for ultimately turning QoE-aware network and application management into reality.

Quality of User Experience in 5G-VANET

“…In order to quantify QoE and translate it into user experience, QoE management has been approached from multiple complimentary perspectives. In [30], Skorin-Kapov et. al.…”

“…lists them as; QoE-driven application management, QoE-driven network management, QoE-driven user monitoring and cross-layer QoE management. Most research conducted in this area supports multi-layer or cross-layer QoE management [30]. Inspired by the existing proposals, Figure 1 illustrates a generic QoE model which leverages the 5G features and support multiple vendors/stake-holders in the business model.…”

“…Multi-layer (including cross-layer) QoE models have been proposed in the literature previously and usually comprises of QoE modelling, monitoring and management components. An extensive survey is conducted by Skorin-Kapov in [26,30].…”

“…Identification of relevant QoE parameters and the degree of their impact is established and defined within the QoE model which then help shape the QoE monitoring and management approaches. Generic relationship between QoE and QoS has been intensively discussed in literature [30], but mainly with a focus on single QoS parameters. However, the organic relationship between them, and how to best model it is not yet clear.…”

“…Monitoring data needs to be fed to a control plane that is capable of driving QoE control. Furthermore, with standardized northbound APIs, mechanisms are provided for applications to provide requirements to the controller (driven by QoS-to-QoE mapping models), which can in turn invoke traffic management mechanisms to meet differentiated service requirements [30]. As discussed, the SDNC's global view of the network is used to inform e.g., media elements, about how to manage quality.…”
