Question: What is the primary purpose of the Nnef_AMPolicyAuthorization_Create service operation in the 5G System (5GS)?
Option 1: To retrieve the subscribed event(s) from the UE.
Option 2: To authorize the request and trigger an Npcf_AMPolicyAuthorization_Create, potentially translating GPSI to SUPI.
Option 3: To provide the policy duration for the created application context.
Option 4: To notify the PCF about the success or failure of the service operation.
Explanation: The primary purpose of the Nnef_AMPolicyAuthorization_Create service operation is to authorize the request and trigger an Npcf_AMPolicyAuthorization_Create, potentially translating GPSI (Generic Public Subscription Identifier) to SUPI (Subscriber Permanent Identifier). This is evident from the description of the service operation in the 3GPP TS 23.502 specification.
