Europe is working on the deployment of 5G cross-border corridors for Connected and Automated Mobility (CAM) on European transport paths.

This deployment, at technological level, is being possible thanks to the following technological enablers:

1. Edge Computing: Edge Computing is similar to cloud computing, however the storage and compute capabilities are extended at the network’s edge by deploying servers in the edge sites closer to the end-users. Data transmission to and from the cloud won’t be necessary, enabling faster data transmission and processing and better service performance.  
2. QoS Prediction: The QoS-GW provides a means of adaptive per-application policy routing able to dynamically change the RAN used to deliver and receive traffic to/from the ground while providing both IP mobility support and application session continuity.
3. V2X Message Routing: Cellular V2X (C-V2X) is the technology developed in 3GPP1 and is designed to operate in two modes: Device-to-device (V2V, V2I, V2P) and Device-to-network (V2N).
4. MNO: A mobile network operator, abbreviated as MNO and sometimes also known as carrier service provider, mobile phone operator or mobile network carrier, is a telecommunications service provider organisation that provides wireless voice and data communication for its subscribed mobile users.

Besides these ones, the 5GMED project is using other technologies to tackle the 5G cross-border issues, that you can check at the 5GMED Lexicon.
