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

Cooperative, Connected and Automated Mobility (CCAM) 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 5GMED project proposes a novel 5G network architecture for the Mediterranean corridor cross-border between Spain and France, where the challenges imposed by CCAM 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 large-scale trials.
