Air-to-ground communication technology is at the heart of the end-to-end air traffic management concept, which requires the global integration of current, future, and emerging communication networks. The project addresses an innovative solution enabling effective, seamless, interoperable air-to-ground datalink communication technologies and digital flight monitoring and management environment through aeronautical telecommunication (ATN) based on internet protocol suite (IPS) within all domains of flight. The project proposes a beyond the state-of-the-art IP-based datalink communication solution by introducing an application-layer mobility management for ATN and enabling the use of commercial of-the-shelf equipment.
