Question: In a cellular network, what is the primary purpose of measuring SFN-CFN (System Frame Number - Cell Frame Number) observed time difference with high accuracy during handovers?
Option 1: To optimize data transmission rates between the User Equipment (UE) and the serving cell.
Option 2: To enhance location services by triangulating the UE's position using neighboring cells.
Option 3: To improve voice call quality by reducing jitter in the radio access network.
Option 4: To accurately identify the time difference between the active cell and neighboring cells for seamless handover.
Explanation: Accurate SFN-CFN observed time difference measurement is crucial for identifying the time offset between the serving (active) cell and neighboring cells. This information is vital for ensuring seamless handovers, as it allows the network to synchronize the UE's transition between cells, maintaining connectivity and service quality.
