Congestion In LTE

[khalids]

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

hi buddy,
hope this will help...mainly it is related to increase throughput...

check below counters,thanks

L.E-RAB.FailEst.NoRadioRes
L.E-RAB.FailEst.NoRadioRes.PUCCH
L.E-RAB.FailEst.NoRadioRes.SRS

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%

all good advice but still missing the BBU capacity number of users... and that affects the whole eNodeB

Good point, kindly how to check

[oswe]

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...

dears
Find below the capacity check for all technologies,thanks
