Question: In a Policy and Charging Control (PCC) scenario, what is the primary purpose of using the same value for the Sharing-Key-DL (DownLink) AVP across different Application Function (AF) sessions for the same user?
Option 1: To prioritize resource allocation for specific media components.
Option 2: To enable resource sharing between different users on the same network.
Option 3: To differentiate between uplink and downlink data transmissions.
Option 4: To indicate that resource sharing applies between media components across these sessions.
Explanation: The correct answer highlights the key role of the Sharing-Key-DL AVP in signaling whether resource sharing is permitted among different media components of the same user's AF sessions. Using the same value signifies that these components can share resources in the downlink direction, crucial for efficient network resource management and ensuring Quality of Service (QoS) for multimedia services.
