What reselection parameters can prioritize one UMTS layer over others?


#1

Hi experts any reselection parameters to prioritize one umts layer? Vendor is ZTE.


#2

Qoffset2SN is used for layers priority


#3

I want to prioritize 850 layer to may i should increase or decrease


#4
  • value increases the priority while negative decreases

#5

You can also use qoffset1sn and individualoffset


#6

That will be on relation level some other parameter in general for priority reselection on specific layer


#7

Is there any other parameter to prioritize 850 layer in an area.not on single site or cell level ?


#8
  1. reduce qrxlevmin and qqualmin in the other layer, but beware of the drops

  2. a well defined core and border strategy

Then, What is the other layer, 1900?


#9

The other layer is 2100


#10

850 will have better propagation, penetration and more traffic, but if you need to prioritize more 850 you can also try adjusting the sIntraSearch and sInterSearch

By the time 2G 900mhz is handing over to 3G 2100mhz due to coverage, not call can even be sustained. You should not handover from 2G 900 to 3G 2100
