Question: What information does an AF include in a request to invoke Nnef_MemberUESelectionAssistance_Subscribe service operation for receiving a list of UEs that match or exceed QoS filtering criteria?
Option 1: Only the mandatory parameters.
Option 2: The mandatory parameters, QoS filtering criteria, and optionally, an Area of Interest.
Option 3: The mandatory parameters, QoS filtering criteria, DNN, S-NSSAI, and one or more of the QoS parameters subject to QoS monitoring.
Option 4: The mandatory parameters, Application ID, and one or more of the QoS parameters subject to QoS monitoring.
Explanation: According to the text, an AF includes in the request the mandatory parameters, QoS filtering criteria, and optionally, an Area of Interest (location area of the candidate UEs). This is because the AF needs to specify the QoS filtering criteria and may also want to limit the search to a specific location.
