Congestion In LTE
Dear Experts,
How can one determine radio congestion in LTE.
What KPI's to look for, what threshold, what trend. When to trigger upgrades.
Documents or explanation would be most appreciated

Re: Congestion In LTE
check below counters,thanks
L.E-RAB.FailEst.NoRadioRes
L.E-RAB.FailEst.NoRadioRes.PUCCH
L.E-RAB.FailEst.NoRadioRes.SRS

Re: Congestion In LTE
in case of e*******, you can check PUCCH congestion count also

Hi, please try build new KPI about Hard Congestion, Soft Congestion, Paging Congestion, Radio Resource capacity.
RRC resource congestion rate = L.RRC.SetupFail.ResFail/L.RRC.ConnReq.Att*100 <0%
E-RAB resource congestion rate = L.E-RAB.FailEst.NoRadioRes/L.E-RAB.AttEst*100<0%
UL_PRB_Utilization_Rate = L.ChMeas.PRB.UL.Used.Avg/L.ChMeas.PRB.UL.Avail*100 <70% && UL User Throughput = L.Thrp.bits.UL/L.Thrp.Time.UL/1000 >512kbps
DL_PRB_Utilization_Rate = L.ChMeas.PRB.DL.Used.Avg/L.ChMeas.PRB.DL.Avail <70% && DL User Throughput = L.Thrp.bits.DL/L.Thrp.Time.DL/1000000 >5Mbps
PUCCH IN (Interference Noise) = (L.UL.Interference.PUCCH.Index0 x Intf (0) + L.UL.Interference.PUCCH.Index1 x Intf (1) +...+ L.UL.Interference.PUCCH.Index15 x Intf (15))/(L.UL.Interference.PUCCH.Index0 + L.UL.Interference.PUCCH.Index1 +...+ L.UL.Interference.PUCCH.Index15) ≤-105dBm
PUSCH IN (Interference Noise) = L.UL.Interference.Avg ≤-100dBm
CCE usage = (L.ChMeas.CCE.CommUsed + L.ChMeas.CCE.ULUsed + L.ChMeas.CCE.DLUsed) / L.ChMeas.CCE.Avail *100 <70%

Re: Congestion In LTE
all good advice but still missing the BBU capacity number of users... and that affects the whole eNodeB

Good point, kindly how to check

Re: Congestion In LTE
cant help you much you need documentation... it´s a table like this. sum up users in all sectors and if close to this ...then you cant do much to avoid congestion...
