What is the purpose of the N3 PDU Set metadata sent by the UPF to the RAN?
To indicate whether or not a PDU is the last PDU of a certain PDU Set
To identify the position of each received PDU within the PDU Set
To select the GTP-U tunnel for forwarding the PDU Sets
To determine the beginning and the end of a PDU Set
To specify the QoS Flow ID associated with the PDU Set
