Question: In a 3GPP network, when an IP BS manager is present in the User Equipment (UE), what is the primary function of the Translation/Mapping function with regards to QoS parameters?
Option 1: To derive Authorized UMTS QoS parameters from AF session signalling
Option 2: To map IP QoS parameters to corresponding UMTS QoS parameters for multiplexed IP flows
Option 3: To compare received UMTS QoS parameters against Authorized UMTS QoS parameters
Option 4: To generate service information from SDI for the PDF
Explanation: When an IP BS manager is present in the UE, and multiple IP flows are multiplexed onto the same PDP context, the Translation/Mapping function maps IP QoS parameters to corresponding UMTS QoS parameters, ensuring compatibility for efficient transmission over the UMTS network.
