Question: How does a PEGC serve multiple PINs in a 5GS network?
Option 1: A PEGC can use a single PDU session to serve multiple PINs, and differentiate or isolate traffic for each PIN using different DNNs and S-NSSAIs.
Option 2: A PEGC must use a separate PDU session for each PIN, and cannot share a PDU session among multiple PINs.
Option 3: A PEGC can only serve one PIN per PDU session, but can have multiple PDU sessions to serve different PINs.
Option 4: A PEGC cannot serve multiple PINs, and each PIN must be served by a separate PEGC.
Explanation: According to the text, a PEGC may use a single or multiple PDU sessions to serve multiple PINs. If differentiation or isolation for the traffics to/from different PINs via PEGC is not required in 5GS, one PDU Session may be shared by more than one PIN served by the PEGC. Otherwise, different DNNs and S-NSSAIs shall be applied to distinguish the PINs by different PDU sessions of the PEGC.
