Hi all,
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.
RXLEV_DL_ZONE=-92
RXLEV_UL_ZONE=-102
ZONE_HO_HYST_DL=18
ZONE_HO_HYST_UL=18
Which of the parameters should i changed and what will be the value.try
RXLEV_DL_ZONE=-92
RXLEV_UL_ZONE=-102
ZONE_HO_HYST_DL=16
ZONE_HO_HYST_UL=13it 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 🙂 )regards
pixOFFSET_HO_MARGIN_INNER=10
Is it good to try with:
RXLEV_DL_ZONE=-92
RXLEV_UL_ZONE=-102
ZONE_HO_HYST_DL=16
ZONE_HO_HYST_UL=16In this way can i move the traffic in the inner zone and eliminate the call congestion.
new boy,
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 HOEN_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 🙂regards
OK pix,thnks.
But i want to ask you something:
if i make
ZONE_HO_HYST_DL=20
ZONE_HO_HYST_UL=20
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 matchnew boy,
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_DLAND
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.regards
