System Implementation of AUSF Fault Tolerance
In this study, we deal with two topics. The first is that a machine, named Mediator, is added to a 5G system for managing and keeping track of UE’s authentication. The purpose is that when an AUSF fails, other AUSFs can successfully take over its authentication process on UEs. The second is that the proposed mechanism can detect this failure immediately and response properly, aiming to increase the QoS that an UE can receive from 5G networks. Experimental results show that the proposed system is better than those compared systems.
