Question: In an Evolved Packet Core (EPC) network, how is the 'Max Number of Active EPS Bearers' measurement typically obtained for Performance Management (PM) purposes?
Option 1: By continuously monitoring and averaging the number of Active EPS Bearers over a predefined period.
Option 2: Through event-triggered reporting each time an EPS Bearer is established or terminated.
Option 3: By sampling at a pre-defined interval, the number of Active EPS Bearers, and then taking the maximum value.
Option 4: Via periodic polling of User Equipment (UE) for their current EPS Bearer status.
Explanation: The correct approach involves periodically checking the current number of active bearers at a pre-defined interval and identifying the maximum value from these samples, capturing peak usage crucial for network capacity planning and performance optimization in EPC networks.
