Question: In GPRS networks, what is the primary purpose of using different types of packet filters for classifying a given PDP (Packet Data Protocol) PDU (Protocol Data Unit)?
Option 1: To determine the right PDP context based on traffic type or PDN (Packet Data Network) QoS capabilities.
Option 2: To prioritize voice over data packets in the network.
Option 3: To encrypt sensitive user data within the PDU.
Option 4: To reduce the overall size of transmitted PDUs.
Explanation: In GPRS networks, packet filters classify incoming packets (PDP PDUs) to ensure appropriate handling. The primary purpose is to examine traffic type or PDN QoS capabilities, determining the correct PDP context for efficient network operation and meeting service level agreements for various data services.
