Multi-Domain Architecture for CAM Service Delivery Across Borders

Connected and Automated Mobility (CAM) encompasses different driving (automated, awareness, sensing, tele-operated), multimodal and infotainment on the move services. These services have been defined with the objective to increase the road safety, improve the traffic efficiency, reduce the environmental impact of transportation and bring travel comfort to passengers and drivers. Relevant technological tasks, stemming from the highly dynamic vehicular environment, need to be solved in order to deliver seamless CAM services with the expected QoS. The cross-border scenario brings the additional challenge of supporting uninterrupted CAM services in a multi-domain environment, namely when the user leaves the serving mobile cellular network to join the newly visited one. We define a multi-domain architecture with an ETSI Zerotouch networking and service management compatible integration fabric to facilitate cross-domain service management and CAM service roaming.
