    Post 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

    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

    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...
