[jayk]

Many failures are happening due to L.E-RAB.FailEst.MME. Someone has analyzed these failures? Please share probable reasons. Thanks.

Hi,

This counter is pegged when eNB fails to carry out validity check of E-RAB SETUP REQUEST from MME as described in the documentation. However it can also be incremented due to MME timeout if no reply is received from UE during access or HO (due to RF issue or abnormal UE behavior).
