Question: What additional parameters may an Application Function (AF) include in a request to invoke Nnef_MemberUESelectionAssistance_Subscribe service operation for end-to-end data volume transfer time related filtering criteria?
Option 1: Only the mandatory parameters are required, and no additional parameters can be included.
Option 2: The AF may include the average end-to-end data volume transfer time for a specific data volume between UE and AF, but not the variance of the end-to-end data volume transfer time.
Option 3: The AF may include the average end-to-end data volume transfer time for a specific data volume between UE and AF, the variance of the end-to-end data volume transfer time, an Area of Interest, and/or time windows for selecting the candidate UEs.
Option 4: The AF may only include an Area of Interest or time windows for selecting the candidate UEs, but not any end-to-end data volume transfer time related filtering criteria.
Explanation: According to the 3GPP TS 23.502 specification, when invoking Nnef_MemberUESelectionAssistance_Subscribe service operation with end-to-end data volume transfer time related filtering criteria, an AF may include additional parameters such as the average end-to-end data volume transfer time for a specific data volume between UE and AF, the variance of the end-to-end data volume transfer time, an Area of Interest, and/or time windows for selecting the candidate UEs. This allows the AF to provide more specific filtering criteria to receive a list of UEs that fulfill those criteria.
