The study of MME pool management and fault tolerance in 5G networks with SDN controllers

Abstract

In this study, we would like to deal with two topics. The first one is that we add a machine, named Mediator, to SDN Controller for managing and keeping track of the data generated by MME during UE authentication. When a VM fails, other MMEs can successfully take over its authentication tasks. The second is that when an MME fails, other MMEs can know this immediately and response properly. The purpose of these is to increase the QoS an UE can receives.
