Huawei E-Rab Access Fail MME
Dear experts,
I'm having Accessibility issues in ourLTE network. Almost all of the access fails added to the L.E-Ran.FailEstab.MME
From the S1 trace I see that the UE Context Fail return from eNodeb due to "interaction with another procedure". Additionally Error Indication message contains "unknown pair ue S1AP ID.
Overall Accessibility rate is around 98.xx %, but my target is 99.50%
So, anyone studied this issue before?
Thanks in advance.
Regards.

Looks interesting, but never seen this issue. Have you tried raising this issue with MME team? They might have more details around this? Looks like an MME issue.

Thanks for your responses.
The EUTRAN is Huawei, MMEs are from E//. I raised the issue to the operator for further investigation with MME team, but they did not yet responded.
