The architecture enhancements for UAVs introduce the following functionalities:
Authentication and authorization of a UAV with the USS during 5GS registration (optional).
Authentication and authorization of a UAV with the USS during PDU session establishment and PDN connection establishment.
Support for USS authorization of C2 Communication.
A reference model for UAV tracking, supporting three UAV tracking modes: UAV location reporting mode, UAV presence monitoring mode, and list of Aerial UEs in a geographic area. The 3GPP system supports geofencing (for in-flight UAV) and geocaging (for UAV on the ground intending to fly) functionality in USS by providing enablers such as location services, event notification to a subscribing USS, etc.
Support for Broadcast Remote ID using MBS.
Support for Direct C2 Communication.
Support for Detect and Avoid mechanisms based on PC5 reference point.
Support for Broadcast Remote ID using PC5 reference point.
