Mapping of QoS/QoE in 5G Networks

Abstract

5G technology will dramatically change the way of living. With a flexible combination of developing existing technology solutions and new radio concepts, and meeting the requirements for efficiency and scalability, the 5G network can respond to new user scenarios followed by a large increase in traffic and number of connected devices. This coming era of 5G network is demanding dynamic resource sharing and context sharing with seamless high speed connectivity everywhere. The challenge for operators is to understand and manage both the quality and performance of the services to fulfill on the technical quality of service (QoS) as well as on the quality of experience (QoE) level. Quality of experience is the subjective acceptability of the quality of a telecommunication service perceived by the user. This contrasts with quality of service, which concerns objective and technical metrics at network and application level. The identification of service-relevant QoE metrics and modeling of how these are affected by the different 5G QoS metrics is discussed in this paper. The impact of QoS parameters on QoE and the possible scenario of QoS/QoE mapping process are presented.
