All eNBs alarming S1 Interface Reset Events Intermittently

Hello Experts.
All eNBs in my network are alarming S1 Interface Reset Events Intermittently.
Initiation mode=Initiated by the MME.

RAN Vendor=Huawei
Core Network Vendor= Ericsson

Any suggestions?

Check TX link downtime between eNB and MME.

Hello @adish_sood, no Tx downtime.

Check if don’t any update in the Core side MME.

No changes on MME end, event active for the last 3 months.

If the alarm is on the same time, maybe you have a operation on the MME.

No operation on MME, the alarm has been intermittently for the last 1 year.
