Can any one tell how to capture the root cause of “L.E-RAB.FailEst.MME” this specific failures?
Let’s assume cell is not overshooting and field SNR is fine as well.
The MME drops are usually caused by radio issues but they are pegged under MME drops because the eNB has no way of knowing that the drop was caused by a radio issue.
It could be well due to late handovers triggered or due to RLFs.
But for RLF timers expiry, CQI missing reports, Radio connection with UE lost the eNB knows the reason is Radio…
