5GMED Architecture for Advanced Automotive and Railway Communication Services in Cross-Border Scenarios

Connected and Automated Mobility (CAM) and Future Railway Mobile Communications System (FRMCS) use cases present strict requirements in terms of service end-to-end latencies, data rates, reliability and service availability, posing challenges in the design of 5G network architectures for cross- border scenarios, where current roaming mechanisms introduce large latencies and service disruption times. The EU-funded Horizon 2020 5GMED project proposes a novel 5G network architecture for the Mediterranean corridor cross-border between Spain and France, where the challenges imposed by CAM and FRMCS in cross-border scenarios are addressed. In this paper, we describe cross-border challenges and present the 5GMED network architecture that will be deployed and evaluated in largescale trials.
