Prospects and QoS requirements in 5G networks

Abstract

In this article the requirements to some number of KPI that determine the quality of service (QoS) in 5G networks are formulated. The proposed QoS requirements are based on the analysis of functional requirements to 5G networks and traffic parameters for HD video and massive M2M services, which will be highly demanded in 2020. One of the 5G development paradigms is the network function virtualization (NFV) including cloud radio access and cloud core networks. The authors have proposed the concept of function blocks CQMF and CQCF to control and monitor QoS, which are implemented as part of the 5G network cloud infrastructure.
