there it is…
It can be used to find out how many RRC FAILED AFTER ADMISSION :
pmTotNoUtranRejRrcConnReq – pmNoRejRrcConnMpLoadC – pmNoRrcReqDeniedAdm + pmNoLoadSharingRrcConn – pmNoRejRrcConnRrcLc
And also how many RRC FAILED due to RADIO TIMEOUT
pmTotNoRrcConnectReq – pmTotNoRrcConnectReqSuccess – pmTotNoUtranRejRrcConnReq
But yeah, basically, it’s a big counter that includes many kind of fails.
