Abstract
In this study, we propose a fault tolerant mechanism for 5G end-device authentication, named Fault Tolerant 5G Authentication Scheme (FT5AS), in which a machine, named Mediator, is added to manage and keep track of authentication steps of end devices (UEs as the examples in the following). The purpose is that when a VM fails, other AUSFs can successfully take over its authentication tasks on UEs. Also, the FT5AS can detect this failure immediately and response properly, aiming to increase the QoS that an UE can receive from 5G networks. The second is that the VMs of each network entity are managed by VMware ESXi. If a VM fails, it can be restarted and restored autonomously. Our simulation results show that the FT5AS has better performance than that of compared scheme which is VSphere FT.
