Question: What is the minimum repetition period for broadcasting a Cell Broadcast Service (CBS) message over the air interface in GERAN and UTRAN respectively?
Option 1: 0.5 s (GERAN), 0.2 s (UTRAN)
Option 2: 1.883 s (GERAN), 1 s (UTRAN)
Option 3: 2 s (GERAN), 1.5 s (UTRAN)
Option 4: 5 s (GERAN), 3 s (UTRAN)
Explanation: The correct answer reflects the technical specifications for the minimum broadcast repetition periods in different network types. In GERAN, the minimum period is approximately 1.883 seconds, aligning with a specific multiframe sequence duration on the radio interface. For UTRAN, the minimum repetition period is defined as 1 second, leveraging its higher capacity for message broadcasting.
