Question: In a UTRAN environment, what is the primary purpose of verifying GSM Carrier RSSI measurement accuracy in CELL_DCH state for a User Equipment (UE) that requires compressed mode?
Option 1: To evaluate the feasibility of UTRAN to GSM handover.
Option 2: To optimize UTRAN cell coverage and reduce interference.
Option 3: To ensure UE's power consumption is within specified limits during handovers.
Option 4: To test the UE's ability to perform simultaneous GSM and UTRAN measurements.
Explanation: Verifying GSM Carrier RSSI measurement accuracy in CELL_DCH state, especially for a UE needing compressed mode, directly impacts the reliability of handover decisions from UTRAN to GSM. Accurate measurements are crucial for seamless handovers, ensuring the UE switches to the GSM network at the right moment based on signal strength, thus maintaining connectivity and service quality, aligning with evaluating the effectiveness of UTRAN to GSM handovers.
