Question: In the Policy and Charging Control (PCC) architecture, when the Policy and Charging Rules Function (PCRF) provides authorized Quality of Service (QoS) for both an IP-CAN bearer and PCC rule(s), what is the order of enforcement?
Option 1: The authorized QoS of the IP-CAN bearer is enforced first, followed by the individual PCC rules.
Option 2: The enforcement of authorized QoS is simultaneous for both IP-CAN bearer and PCC rules.
Option 3: The PCRF dynamically decides the order based on the service-based policies.
Option 4: The authorized QoS of the individual PCC rules is enforced first, followed by the IP-CAN bearer.
Explanation: The correct answer reflects the specified order of enforcement: the authorized QoS of individual PCC rules takes precedence and is enforced before that of the IP-CAN bearer when both are provided by the PCRF, highlighting the importance of rule-based QoS management in ensuring service quality.
