Question: What is the primary purpose of measuring the 'Mean number of PDU sessions being allocated' in a 5G network, as related to Radio Resource Management (RRM)?
Option 1: To optimize packet switched traffic routing in the core network.
Option 2: For billing purposes based on the number of active PDU sessions per user.
Option 3: To monitor the overall network latency and its impact on QoS.
Option 4: To support RRM resources optimization for performance assurance.
Explanation: This measurement is crucial for understanding resource utilization across different S-NSSAIs in a cell. Knowing the mean number of allocated PDU sessions helps network operators optimize RRM, ensuring efficient resource use, enhanced network performance, and user experience.
