Question: How does a Mobile Network Operator (MNO) detect and control Unmanned Aerial System (UAS) communication in their network?
Option 1: By monitoring the UAV's radio capability indication to the network.
Option 2: Through subscription information that identifies a UE as an aerial UE.
Option 3: Based on the unique 3GPP credentials and identities of the UAS.
Option 4: By analyzing the communication patterns between the UAV and UAV controller.
Explanation: The MNO uses subscription information to identify if a UE is allowed to function as an aerial UE in the network, which enables them to apply necessary controls and functions, such as uplink power adjustment and frequency band alteration, to prevent impact on other types of communication.
