context: [3] clause 4.2, SSC #2 and SSC #3 mode could be used to optimize traffic routing here for distributed anchor point and multiple PDU session cases. In case of SSC #2 mode, the SMF will release the existing PDU session, and trigger the UE to establish the PDU session2 for the T-EDN according to TS 23.502 [5] clause 4.3.5.1, by sending the PDU Session Release Command message to the UE which contains the PDU Session ID and Cause indicating that a PDU Session re-establishment to the same DN is required. In case of SSC #3 mode, according to TS 23.502 [5] clause 4.3.5.2, the SMF will trigger the UE to establish a new PDU session by sending the N1 SM container (PDU Session Modification Command (Cause, PCO (PDU Session Address Lifetime value)))) where the Cause indicates that a PDU Session re-establishment to the same DN is required. Step 10. (Optional) If a new PDU session is required for the T-EDN, then UE initiates the PDU session2 establishment procedure for the T-EDN. Otherwise, steps 9,
description: SSC modes (#2 and #3) are operational modes used by the SMF (Session Management Function) to manage PDU sessions in specific scenarios. These modes optimize traffic routing for distributed anchor points and handle multiple PDU session cases.
explanation: The text describes SSC modes as operational settings within the SMF that influence how PDU sessions are managed. This aligns with the definition of an operational mode as a distinct configuration setting that dictates the behavior of a system or component.
