Question: What is the primary function of the QoS-Rule-Name AVP in a telecom network, specifically in relation to the PCRF and BBERF entities?
Option 1: To allocate IP addresses for User Equipment (UE) across different access types.
Option 2: To define a priority level for signaling messages between the MME and SGW.
Option 3: To identify a specific bearer resource in the E-UTRAN for QoS management.
Option 4: To uniquely identify a QoS rule within a Gateway Control session (for PCRF-provided rules) or within the BBERF (for pre-defined rules).
Explanation: The QoS-Rule-Name AVP's role is to identify QoS rules, crucial for differentiated service treatment in telecom networks. This ensures traffic is managed according to predefined quality of service standards, whether set by the PCRF for broader network policies or pre-defined at the BBERF for localized, access-specific rules, enabling precise application of QoS policies.
