Question: In a Policy and Charging Control (PCC) architecture, when provisioning an Application Detection and Control (ADC) rule, which of the following QoS attributes can the Policy and Charging Rules Function (PCRF) use to limit bandwidth for an application’s traffic in the uplink direction?
Option 1: Max-Requested-Bandwidth-UL AVP or Extended-Max-Requested-BW-UL AVP
Option 2: Min-Requested-Bandwidth-DL AVP only
Option 3: Guaranteed-Bitrate-UL AVP and Peak-Bitrate-UL AVP
Option 4: QoS-Class-Identifier AVP alone
Explanation: According to the PCC specifications for bandwidth limitation in ADC rules, the PCRF can enforce policy by providing either the Max-Requested-Bandwidth-UL AVP or its extended counterpart, Extended-Max-Requested-BW-UL AVP, specifically for uplink traffic. These attributes directly relate to limiting the maximum requested bandwidth in the uplink direction, making them the correct choices for enforcing such a policy on an application’s detected traffic.
