Question: How does the UPF suspend traffic duplication for a UE in a Redundant steering mode?
Option 1: By sending PMF-Suspend Duplication Request via the control plane of the MA PDU session.
Option 2: By sending PMF-Suspend Duplication Request via the user plane of a specific access of the MA PDU session.
Option 3: By sending PMF-Suspend Duplication Request via the user plane of any available access of the MA PDU session.
Option 4: By sending PMF-Resume Duplication Request via the control plane of the MA PDU session.
Explanation: In a Redundant steering mode, the UPF can suspend traffic duplication for a UE by sending a PMF-Suspend Duplication Request message. This message is sent via the user plane of any available access of the MA PDU session, allowing the UPF to dynamically manage traffic duplication without relying on a specific access.
