Question: What is the primary purpose of reporting RAN User Plane Congestion Information (RUCI) to the Policy and Charging Rules Function (PCRF)?
Option 1: To enable the PCRF to make policy decisions based on the RAN user plane congestion status.
Option 2: To update the UE's IMSI in the network's subscriber database.
Option 3: To notify the eNB of changes in the APN configuration.
Option 4: To trigger a handover from one eNB to another due to congestion.
Explanation: The primary purpose of reporting RUCI to the PCRF is to provide real-time insights into the RAN's user plane congestion status, enabling informed policy decisions for managing network resources and maintaining Quality of Service (QoS) for impacted UEs.
