Question: In a network-initiated IP-CAN session modification, how does a PCEF handle precedence values for multiple TFT filters derived from one PCC rule?
Option 1: Assigns the same precedence value to all TFT filters across the PDN connection.
Option 2: Randomly assigns unique precedence values to each TFT filter without considering the PCC rule's precedence.
Option 3: Ensures each TFT filter has a precedence value based on the UE's subscription profile.
Option 4: Assigns unique precedence values to each TFT filter, ensuring consistency across all filters of the corresponding PDN connection.
Explanation: This is correct because when one PCC rule results in multiple TFT filters during a network-initiated IP-CAN session modification, the PCEF must ensure that each TFT filter is assigned a unique precedence value. This uniqueness must be maintained across all TFT filters of the corresponding PDN connection to avoid conflicts and ensure proper prioritization of traffic, aligning with efficient policy and charging control (PCC) in telecom networks.
