Question: When authorized QoS applies to a specific Quality of Service Class Identifier (QCI) in a 3GPP-GPRS access network, how is the authorized Maximum Bit Rate (MBR) per QCI typically provisioned by the Policy and Charging Rules Function (PCRF) to the Policy and Charging Enforcement Function (PCEF)?
Option 1: Within the Charging-Rule-Definition AVP, including the QoS-Information AVP.
Option 2: Outside a Charging-Rule-Definition AVP, at the command level, supplying authorized MBR per QCI.
Option 3: As part of the Default-EPS-Bearer-QoS AVP for all bearers.
Option 4: Through a separate IP-CAN bearer-specific message, not via Diameter AVPs.
Explanation: When the authorized QoS applies to a QCI (especially in non-GBR bearers with a separate MBR), the PCRF supplies the authorized MBR per QCI outside of a Charging-Rule-Definition AVP, directly at the command level. This approach is specific to managing resources for QCIs that require an upper limit for the MBR assigned to non-GBR bearers with that QCI, ensuring proper resource allocation and enforcement by the PCEF.
