Question: In a Policy and Charging Control (PCC) context, what is the primary purpose of the QoS-Rule-Remove AVP in relation to a Gateway Control session?
Option 1: To activate new QoS rules for enhanced user experience across all access types.
Option 2: To deactivate or remove specific or predefined QoS rules at the Broadband BRAS/BNG (BBERF).
Option 3: To modify existing QoS rule parameters for better network optimization.
Option 4: To request additional access network information from the User Equipment (UE).
Explanation: The QoS-Rule-Remove AVP is designed to deactivate or remove QoS rules, either by referencing a specific rule or a group of predefined rules at the BBERF, thereby managing and adjusting the quality of service for Gateway Control sessions.
