Quality of Service (QoS) oriented management system in 5G cloud enabled RAN

Abstract

[EN] This paper analyze techniques to implement QoS/QoE on multi-tenant 5G networks. Describes the ar- chitecture of the next generation mobile network based on cloud-enabled small cell deployments and also proposes an hybrid-cloud solution coexisting with centralized cloud RAN(C-RAN), in order to achieve a gradual implementation of the technology. In this context, the work here presented deals with the challenges of preserving the quality of ex- perience in a multi-tenant cloud enable RAN bearing in mind the Key Performance Indicator(KPI) agreed in the SLA. To achieve this goal, QoS should be managed at different levels of the architecture. Feedback should be given between learning modules in order to analyze the results and infer enhanced decision rules which may conclude in an architecture replacement.
