Hello there,

Do you have a similar document for 3G.

Thanks Antonski.....I have set these values and waiting for the reports....]


I think you have to set the flag TRFHOE=TRUE in target cells too, perhaps the reason behind that is the necessary calculation of the "traffic budget" in the target cell before consider it suitable.

Below you can find the parameters used for system acceptance tests, where BTS:0 is source cell and BTS:1,2,3 are target cells:

1. SET BSC [BASICS]:
TRFCT=10; (traffic control timer, this timer specifies the cycle, in which the
BSC periodically checks the traffic situation in all its cells.)

2. SET HAND [BASICS]:NAME=<bts0>,
TRFHOE=TRUE, (traffic HO enabled flag)
TRFHITH=60, (traffic load threshold for enabling of traffic HO)
TRFLTH=40, (traffic load threshold for incoming traffic handover acceptance)
TRFHOT=10, (traffic HO escalation/de-escalation timer)
TRFMS=1, (traffic HO margin reduction stepsize and minimum reduction for traffic HO margin)
TRFMMA=4, (maximum traffic HO margin reduction)
TRFKPRI=FALSE, (traffic keep priority, if TRUE, then a target cell MUST have
the equal priority level like the serving cell,
if FALSE, an equal or higher one.)
3. SET HAND [BASICS]:NAME=<bts1,bts2,bts3>,
TRFHOE=TRUE, (traffic HO enabled flag)
TRFHITH=90, (traffic load threshold for enabling of traffic HO)
TRFLTH=70; (traffic load threshold for incoming traffic handover acceptance)
4. SET ADJC:NAME=< bts0->bts1, bts1->bts0 >
TRFHOM=53*, (traffic handover margin, 53 ( -10dB) *
BHOFOT=20; (back handover forbidden timer, determines how long
back handovers due to traffic or power budget are
not allowed after successful completion of a
traffic handover).
TRFHORXLVMOFF=6; (traffic handover RX level offset, is added to
RXLEVMIN for the calculation of the traffic
handover minimum criterion, default value is
TRFHORXLVMOFF= 6dB

* Attention!
For dualband neighbour cell relations the TRFHOM has to be adapted (+3dB for GSM->DCS, and –3dB for DCS->GSM relations):
TRFHOM = 53 (for DCS->DCS and GSM->GSM)
TRFHOM = 56 (for GSM->DCS)
TRFHOM = 50 (for DCS->GSM)

**************
Hope this helps.

did you have some document about your explanation on above?

I have doc about that.. you can PM me..

did you have some document about your explanation on above?

Recently I've downloaded a BR10 Database Engineering Manual, the best (actually the only) description of Siemens DB parameters.
I didn't find the same topic in the Library section, but I found another one:
http://www.finetopix.com/nokiasiemen...ng-manual.html

I could share a test case manual regarding the topic, but I still don't know how to upload documents here.
