Question: What is the primary purpose of the threshold value for uplink interference level and downlink TX power sent from the CRNC to Node B in a UTRAN network?
Option 1: To adjust the transmission power of neighboring cells for better coverage.
Option 2: To trigger immediate handovers when uplink interference exceeds a certain level.
Option 3: To prevent frequent reporting over the Iub interface by setting a threshold for measurement comparisons.
Option 4: To dynamically change the bandwidth allocation based on interference levels.
Explanation: The correct answer is Option 3 because setting a threshold for reporting helps in reducing unnecessary or frequent reports over the Iub interface, optimizing network resource utilization and minimizing signaling overhead by generating reports only when averaged measurements exceed the set threshold.
