This paper describes the ability of 5G networks to be the capable infrastructures to address the situations of connected and automated mobility (CAM). The cross border environments provide an additional challenge for the 5G technology but also for the service continuity and also for the quality of the service as a car crosses a border. This paper identifies two enablers that provide the means for an automated car to have a ubiquitous communication in cross border environments. The enablers provide the mechanisms for notifications on approaching passengers and freight and assignment of necessary resources in the destination network (proactive resource allocation) and the means for service continuity in cross border communications. In order to achieve this, it is important to leverage on heterogeneous inputs from vehicles, transferred goods and people and to propose prediction algorithms for predicting traffic in the destination network and plan accordingly the needed resources.
