Question: What is the primary purpose of the Background Data Transfer (BDT) Notification sent by the Policy Control Function (PCF) to an NF service consumer in a 5G system?
Option 1: To request additional network resources for foreground applications.
Option 2: To inform about a change in the user's subscription plan affecting data limits.
Option 3: To notify about changed network conditions impacting background data transfer, such as degraded network performance in a specific area.
Option 4: To initiate a handover from one base station to another for improved coverage.
Explanation: The correct answer is Option 3 because the BDT Notification is specifically used to inform NF service consumers about changes in network conditions that could affect background data transfers. This includes scenarios where network performance drops below operator-set thresholds, directly impacting how background data is handled. This notification enables the service consumer to adjust its behavior accordingly, ensuring efficient use of network resources for background data transfer.
