Question: What happens to all active Quality of Service (QoS) rules associated with an IP-CAN bearer when the bearer is terminated?
Option 1: They are automatically modified to a default QoS rule set.
Option 2: They are deactivated without explicit instructions from the Policy and Charging Rules Function (PCRF).
Option 3: They remain active and are transferred to another available IP-CAN bearer.
Option 4: Their activation status is temporarily suspended pending PCRF re-evaluation.
Explanation: Upon IP-CAN bearer termination, the system automatically deactivates all QoS rules associated with that bearer. This process occurs independently of explicit instructions from the PCRF, ensuring a controlled shutdown of QoS management for the terminated bearer.
