Hi pix, thank you for your answer!
Yes, you are right, difference between pmTotNoRrcConnectReq and pmTotNoRrcConnectReqSuccess
is high, not the counter pmTotNoRrcConnectReq alone.
I have checked counter pmNoFailedAfterAdm and realise that it’s value is almost the same as difference between pmTotNoRrcConnectReq and pmTotNoRrcConnectReqSuccess on that problematic day.
What are the most common reasons for failed RRCs and RABs after admission?
