Hi All, I have a cell whose performance just suddenly degraded and the counter contributing to the degradation is
pmNoFailedAfterAdm. It is Erisson P6 WCDMA network. Any ideas on what could be the cause of this increase in the number of Radio Resource Control (RRC) or Radio Access Bearer (RAB) establishment requests failed after being admitted by admission Control (pmNoFailedAfterAdm)? Thanks,
What's the following statistics value in the statistics interval?
pmTotNoRrcConnectReq
pmTotNoRrcConnectSetup
pmTotNoRrcConnectReqSuc
pmTotUtranRejRrcConnReq
pmNoDlChCodeAllocAttemptSf128
pmSetupFailureSf64
pmSetupFailureSf128
pmNoCellDchDisconnectAbnorm
pmNoRabEstablishSuccess
pmNoRabEstablishAttempt
A couple of questions to help me understand the problem better as I am unable I access any downloads yet...
1, What service has degraded? - CS, PS, HS or Eul
2, How many cells have been affected? - all cells of the site or just one cell?
3, Do you have the RBS hardware monitor feature active? - are you seeing failures for pmNoFailedRabEstAttemptLackUlHwBest, pmNoFailedRabEstAttemptLackDlHwBest,pmNoRrcReqDeniedAdmUlHw or pmNoRrcReqDeniedAdmDlHw. If you are then RBS hardware monitor is active.
4, How is the transmission configured i.e. number of E1 links + number of cells/site?

1. HS and PS service have degraded; CS is not affected
2. Just one cell of the site is affected.
3. pmNoFailedRabEstAttemptLackUlHwBest, pmNoFailedRabEstAttemptLackDlHwBest,pmNoRrcReqDeniedAdmUlHw or pmNoRrcReqDeniedAdmDlHw are not available in my system.
4. 2 E1s are connected to the site.

Is there any aal2 congestion? Is your virtual channels for classes BCD defined correctly?
