Question: In a scenario where the access network does not utilize QCI-based QoS parameters, what is the role of the BBERF (Bearer Binding and Event Reporting Function) regarding QoS parameter conversion?
Option 1: The BBERF ignores QCI values and relies on MBR for resource allocation.
Option 2: The BBERF only converts QoS attribute values to QCI, not the reverse.
Option 3: The BBERF does not perform any conversions and forwards QCI values as is.
Option 4: The BBERF converts a QCI value to access network-specific QoS attribute values and vice versa.
Explanation: This is correct because, when the access network does not use QCI-based QoS parameters, the BBERF is responsible for converting between QCI values and the QoS attribute values used in the access network, ensuring seamless communication and resource allocation across different network types.
