I have a problem. I have a concentric cell with Half Rate for DCS and GSM.
But even though i have high call congestion.The traffic is higher in the outer zone. How can i move the traffic in inner zone.
Which of the parameters should i changed and what will be the value.11th October 2011 at 09:55 #67360pixGuest
it should be better.
how much is your offset margin inner ?
your mstxpwr_max, bs_txpwr_max and bstxpwr_max_inner ? (i’m not sure about the names anymore, i hope you’ll understand what i’m looking for 🙂 )

Is it good to try with:
In this way can i move the traffic in the inner zone and eliminate the call congestion.11th October 2011 at 12:59 #67362pixGuest
well, i don’t know why you want to use 16 instead of 13 as I suggested, but yeah, go ahead.
also, ensure that:
En_better_zone = enable
to allow outer->inner zone HO
EN_LOAD_BALANCE = disable
to allow the inner zone to be fully loaded.
that will create some artificial congestion in “HO_cong_%” but it’s not degrading the qos, it’s just an artefact 🙂

But i want to ask you something:
if i make
what will be the effect?
Is it possible to creat more Blocking?
And if i make this parameter higher then what will be the effect?
Thank you very match11th October 2011 at 13:49 #67364pixGuest
with zone_ho_hyst = 20, MS can barely enter the inner zone.
the condition to enter the inner zone is :
Rxlev(DL OUTER) > RXLEV_DL_ZONE + ZONE_HO_HYST_DL
Rxlev(UL OUTER) > RXLEV_UL_ZONE + ZONE_HO_HYST_UL + 3dB
you shall not go below an hysteresis of 12dB, otherwise there will be ping-pong.
higher than 18dB – and the probability to have enough rxlev to enter the inner zone becomes very thin ! so yes, with 20dB you will create more blocking.
