Question: In a PCC rule request for a GPRS access type, what is the primary purpose of including multiple TFT-Packet-Filter-Information AVPs for each applicable packet filter within a PDP context?
Option 1: To enable the PCRF to prioritize charging based on packet content.
Option 2: To allow the PCEF to dynamically adjust QoS without PCRF intervention.
Option 3: To provide the PCRF with detailed traffic filtering criteria for each PDP context, ensuring accurate policy enforcement and charging control.
Option 4: To facilitate secure key exchange between the UE and the network for encrypted packet transmission.
Explanation: Including multiple TFT-Packet-Filter-Information AVPs for each applicable packet filter within a PDP context allows the PCRF to have granular, detailed information about how traffic should be filtered and managed. This ensures that policy enforcement and charging control are accurately applied for each PDP context, aligning with Policy and Charging Control (PCC) principles in telecom networks.
