Question: What is the primary purpose of the Enhanced-Diagnostics AVP (AVP code 3901) in Diameter charging applications for Telecommunication management?
Option 1: To report the start and end time of a time envelope for offline charging.
Option 2: To provide a set of causes for release, complementing the Change-Condition AVP for Offline Charging from PCN Nodes.
Option 3: To carry volume reports (e.g., CC-Total-Octets) for online charging sessions.
Option 4: To indicate Quota-Consumption-Time changes in a Credit-Control-Answer (CCA).
Explanation: The Enhanced-Diagnostics AVP is designed to offer detailed causes for releases, enhancing the information provided by the Change-Condition AVP specifically for offline charging scenarios involving PCN Nodes. This aligns with the need for comprehensive diagnostics in telecommunication management, particularly in complex network architectures where understanding release causes is crucial for troubleshooting and network optimization.
