Question: Under what condition is UE-initiated IP-CAN session termination **NOT** applicable in a telecom network?
Option 1: When the PCEF triggers the termination due to Subscriber IP session end.
Option 2: In mobile broadband scenarios with active handovers.
Option 3: During IP address lease renewal processes.
Option 4: For Fixed Broadband Access connections.
Explanation: This is because UE-initiated IP-CAN session termination explicitly excludes Fixed Broadband Access connections, highlighting different handling of session terminations based on broadband access type (mobile vs. fixed), impacting network resource management and user experience.
