Question: What is the primary reason for monitoring simultaneous E-RABs in an E-UTRAN cell?
Option 1: To optimize E-RAB setup success rate
Option 2: To reduce signaling overhead
Option 3: To understand resource utilization and perform capacity engineering
Option 4: To improve QoS for high-priority services
Explanation: Monitoring simultaneous E-RABs helps to understand the average/maximum utilization of resources in time periods, which is essential for performing necessary resource capacity engineering. This ensures that the network can handle the expected load and provide optimal performance.
