A Machine Learning-based Framework for Optimizing the Operation of Future Networks

Abstract

The fifth generation of mobile networks (5G) and beyond are not only sophisticated and difficult to manage, but must also satisfy a wide range of stringent performance requirements and adapt quickly to changes in traffic and network state. Advances in machine learning and parallel computing underpin new powerful tools that have the potential to tackle these complex challenges. In this paper, we develop a general machine learning- based framework that leverages artificial intelligence to forecast future traffic demands and characterize traffic features. This enables to exploit such traffic insights to improve the performance of critical network control mech- anisms, such as load balancing, routing, and scheduling. In contrast to prior works that design problem-specific machine learning algorithms, our generic approach can be applied to different network functions, allowing to re-use existing control mechanisms with minimal modifications. We explain how our framework can orchestrate ML to improve two different network mechanisms. Further, we undertake validation by implementing one of these, i.e., mobile backhaul routing, using data collected by a major European operator and demonstrating a 3x reduction of the packet delay, compared to traditional approaches.
