I has problems in balance traffic from DCS 1800 and GSM 900 cell , please your support1st April 2009 at 06:55 #56556TNSGuest
I think the real “support” is vendor depending…

What is your radio network vendor?20th April 2009 at 11:20 #56558KingGuest
Siemens vendor ,
we modify HOM but no change to get balance traffic from DCS 1800 and GSM 900 cell20th April 2009 at 17:42 #56559TNSGuest
I still don’t get it…
You have a multiband cell with not loaded inner zone;
DCS not laoaded cell in GSM area;
GSM not loaded cell in DCS area?
BR22nd April 2009 at 08:22 #56560KingGuest
first thanks for your care…
I have problems in DCS cell loaded traffic more than GSM cell , I need to realize traffic balance between DCS cell and GSM cell
Note : using Siemens vender22nd April 2009 at 21:10 #56561TNSGuest
I’m sorry but my vendor is Alcatel so I can’t give you a exact action plan.
I can tell you how Alcatel ideology is organized.
At BSC level we have a “preffered band” ( in my case it’s DCS ).
This means that when my serving cell is from GSM band the mobile can go to any cell.
But … when the serving cell have a BCCH from the DCS band some HO reasons are inhibited in such way to keep the traffic in the preffered band. It’s very hard to go to “not preffered band” if we don’t enable a specific parameter at cell level.
May be you ( Siemens ) have something similar.
From radio wave propagation point of view it is always eazy to capture traffic on GSM band.
What are MAX Tx POWERs ( BTS GSM and BTS DCS )?
You can’t establish MOC and MTC in the GSM cell or MOC and MTC are established on GSM but there are a outgoing HOs to the DCS cells?23rd April 2009 at 11:53 #56562KingGuest
THE MAX Tx POWERs for BTS GSM
and related BTS DCS
MSTXPMAXGSM=30dBm23rd April 2009 at 15:34 #56563samGuest
I think, you can try with PL=5(D1800) and PL=10(G900)

thank for All
but still unbalance traffic from DCS 1800 and GSM 900 cell28th April 2009 at 16:24 #56565ahmedGuest
Can you please tell me about RCP7th May 2009 at 08:04 #56566TimzGuest
Same problem with me here. I work for an Operator with HUAWEI equipment,cells are congested on 900 Band while 1800 Band is still capable of carrying traffic. We have limited 900 Band frequencies which forced us to deploy only a maximum of two (2)900 TRXs. Anybody with an idea on how to balance/force traffic to 1800 band. Please help coz am new in HUAWEI parameters.

can you give CRO,RX level access min,CBQ,interlayer HO threshold for the network
BR8th May 2009 at 07:47 #56568m12Guest
Depending on your settings, retuning some parameters among the below listed may help you achieve the desired Traffic Balance;
Load HO Allowed
Load HO Threshold
Inter-layer HO Threshold
Tch Traffic busy Threshold(%)
AMR TCH/H Prior Cell Load Threshold
Edge HO UL RX_LEV Threshold
Edge HO DL RX_LEV Threshold
AMR DL RX_LEV Upper Threshold
AMR DL RX_LEV Lower Threshold
AMR UL RX_LEV Upper Threshold
AMR UL RX_LEV Lower Threshold
DL RX_LEV Upper Threshold
DL RX_LEV Lower Threshold
UL RX_LEV Upper Threshold
UL RX_LEV Lower Threshold
UL Expected Level at HO Access.

can anyone suggest how to calculate ESB delay?
