Question: What is the condition for an E-RAB with bursty flow to be considered "in session" for a UE?
Option 1: If any E-RAB data on any Data Radio Bearer (UL or DL) has been transferred during the last 50 ms for that QCI.
Option 2: If any E-RAB data on any Data Radio Bearer (UL or DL) has been transferred during the last 100 ms for that QCI.
Option 3: If any E-RAB data on any Data Radio Bearer (UL or DL) has been transferred during the last 200 ms for that QCI.
Option 4: If any E-RAB data on any Data Radio Bearer (UL or DL) has been continuously transmitted for at least 100 ms for that QCI.
Explanation: According to the text, an E-RAB with bursty flow is considered "in session" for a UE if any E-RAB data on any Data Radio Bearer (UL or DL) has been transferred during the last 100 ms for that QCI. This condition is specific to bursty flows and is used to determine when an E-RAB is considered active.
