Question: In a Universal Terrestrial Radio Access Network (UTRAN), why is it crucial to have a separate counter for cell unavailability due to Energy Saving Management feature?
Option 1: To accurately measure the overall energy consumption of the network.
Option 2: To distinguish cell downtime caused by Energy Saving from other network failures, enabling precise calculation of total cell downtime.
Option 3: To prioritize RRC connection establishment failures over cell unavailability issues for troubleshooting.
Option 4: To evaluate the effectiveness of Energy Saving features on reducing RRC connection attempts.
Explanation: Having a separate counter for cell unavailability due to Energy Saving Management allows network operators to differentiate between planned downtime (for energy saving) and unexpected failures. This distinction is vital for accurate assessment of network reliability and performance, as it enables the subtraction of intentional energy-saving downtimes from the total cell downtime, providing a clearer picture of unforeseen issues affecting the network.
