Question: What is the primary benefit for operators in monitoring the number of connected users in each cell?
Option 1: To optimize handover procedures between cells.
Option 2: To improve the accuracy of location-based services.
Option 3: To enhance security features for individual users.
Option 4: To tune admission control parameters and achieve target QoS through load balancing.
Explanation: Monitoring the number of connected users in each cell provides operators with valuable insights to adjust admission control parameters. This adjustment helps in achieving the desired Quality of Service (QoS) by ensuring that the right number of users are admitted, thus preventing overload and maintaining optimal network performance.
