Question: Upon receiving a Set Request message from the Session Management Function (SMF)/Centralized User Configuration (CUC), how does the Access Network Talker Listener (AN-TL)/Core Network Talker Listener (CN-TL) handle TN stream configurations that are requested to be added and deleted?
Option 1: For added configurations, the AN-TL/CN-TL stores and attempts to apply them, while for deleted configurations, it ignores previous settings but does not remove them.
Option 2: For added configurations, the AN-TL/CN-TL stores and attempts to apply them, while for deleted configurations, it deletes the TN stream configuration.
Option 3: The AN-TL/CN-TL replaces all existing TN stream configurations with new ones regardless of the request type (add or delete).
Option 4: The AN-TL/CN-TL sends a confirmation request back to the SMF/CUC for both added and deleted configurations before taking any action.
Explanation: This is correct because, upon receipt of a Set Request message, the AN-TL/CN-TL stores and attempts to apply new TN stream configurations that are requested to be added, and deletes the TN stream configuration for those requested to be deleted, ensuring dynamic management of TN streams based on SMF/CUC instructions in 5G systems.
