Question: What happens to IP packets when a Gate Function, as described in a PCC rule, is closed for a specific service data flow?
Option 1: The packets are buffered for potential future forwarding.
Option 2: The packets of the related IP flows are allowed to be forwarded with reduced priority.
Option 3: All packets of the related IP flows shall be dropped.
Option 4: The packets are routed through an alternative network path.
Explanation: When a Gate Function is closed for a specific service data flow as per its PCC rule, it results in disabling the forwarding of IP packets belonging to that flow. Consequently, all packets associated with the closed gate are dropped, ensuring controlled network traffic based on predefined policies.
