1. A method performed by a network node of a radio access network (RAN), the method comprising:
establishing a connection with a user equipment (UE) in a cell served by the network node;
determining that the UE is engaged in unauthorized aerial operation; and
based on determining the unauthorized aerial operation, performing the following operations:
restricting the performance of the connection by:
refraining from allocating any cell resources for one or more data radio bearers (DRBs) associated with the connection; and
reducing transmission rates for the one or more DRBs associated with the connection; and
sending to the UE a message comprising:
an indication that the connection will be released; and
one or more conditions that the UE must meet before attempting to reestablish the connection.
