In our network we have many cells having high RRC failures due to “L.RRC.SetupFail.NoReply”. When we trace these cells for RRC failures using Groundhog tool, we dont find any specific UE, rather all are unknown IMSI.
Hardware check was done and didnt find anything. Swapped RRU / changed antennna, changed cards, but still the issue is same.
How can i Identify if this is realted to specific UE when trace shows all as unknown. Is there any other way in huawei to check ?
