Question: What is the condition for a UE to be considered "in session" for E-RABs with bursty flow?
Option 1: If any E-RAB data on a Data Radio Bearer (UL or DL) has been transferred during the last 50 ms.
Option 2: If any E-RAB data on a Data Radio Bearer (UL or DL) has been transferred during the last 1000 ms.
Option 3: If the UE is in idle mode for more than 10 seconds.
Option 4: If any E-RAB data on a Data Radio Bearer (UL or DL) has been transferred during the last 100 ms.
Explanation: For E-RABs with bursty flow, a UE is considered "in session" if any E-RAB data on a Data Radio Bearer (UL or DL) has been transferred during the last 100 ms. This condition helps to accurately measure the aggregated active session time for UEs in a cell.
