Question: What is the purpose of including "Area of validity for the N2 SM information" in the Namf_Communication_N1N2MessageTransfer service operation?
Option 1: To determine the location of the UE.
Option 2: To authenticate the consumer NF.
Option 3: To determine whether the N2 SM information can be used towards the AN based on the current location of the UE.
Option 4: To prioritize the transfer of N1 and N2 messages.
Explanation: The "Area of validity for the N2 SM information" is used by the AMF to determine whether the N2 SM information provided by the consumer NF can be used towards the AN based on the current location of the UE. If the location of the UE is outside the indicated area, the AMF shall not send the N2 SM information to the AN. This ensures that the N2 SM information is only sent to the AN when it is relevant and applicable to the UE's current location.
