Simulation-based evaluation of Quality of Service for 5G network mobility

The networking of vehicles with other road users or the infrastructure (Vehicle-to-Everything (V2X)) is one of the key technologies for autonomous driving and smart cities. The next generation of mobile communications (5G), which is going to be launched in 2020, takes into account use cases and criteria for V2X communication from the very beginning and is a key technology for autonomous driving. Foreseen autonomous driving functions need to be able to execute safety-critical applications and infotainment applications simultaneously. In the context of competition for network resources, a 5G network needs to consider these specific Quality of Service requirements and prefer safety applications at any time. The virtualization of mobile radio components (especially the core network) via network slicing is supposed to play a decisive role for the fulfillment of these QoS parameters in 5G. For the evaluation of various driving functions in the 5G context, BMW is cooperating with the Chair of Computer Networks and Communication Systems of the Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) to set up a 5G V2X simulation environment during the upcoming year. The aim is to evaluate the performance as well as the limits of a 5G network with respect to V2X use cases in different realistic traffic scenarios and to investigate them in detail.
