Sorry you I passed the wrong info:
BS_TXPWR_MAX= 0(full transmit, no att.)
BS_TXPWR_MAX_INNER= 09full transmit, no att.)
MS_TXPWR_MAX= 30dBm..full transmit
MS_TXPWR_MAX_INNER= 30dBm..full transmmit
Zone_HO_HYST_DL/UL = 6dBm
2Tres in outer zone, four TRXs in inner zone with additional ANy Combiner attenuation of 3dB.

it is a monoband 1800 concentric cell ?
what is the value of :
ZONE HO HYST DL
ZONE HO HYST UL
now some analysis :
is CRAZY !!!!
Are you really putting an attenuation of 30dB to your BTS ? Then there is almost no coverage at all.
This value should be 0dB.
that should be a positive value, such as +30dBm (in 1800MHz cell) or 33dBm (in 900Mhz cell)
Waiting for your answers to the first questions...

Cell is located in dense urban area with good network coverage. Pls see my current settings below and advise,
RxLev_UL_Zone = -95dBm
RxLev_DL_Zone = -92dBm
En_Load_Outer = Enable
En_Load_Balance = Disable
En-BetterZone_HO = Enable
T_HCP = 10
Ping Pong HCP = 15secs
Cell Type = Concentric.

have a look to this thread.
Are you using monoband cc cell, or multiband cc cell ? (cc = concentric)
if monoband, then use
ZONE HO HYST DL = 6dBm
ZONE HO HYST UL = 3dBm
MS_TXPOWER_MAX_INNER = 33dBm - the trx attenuation in the inner zone (ie. if attenuation = 10dB, then mstxpowermaxinner = 23dBm)
The parameter neighbour Rxlev(o,n) is very very very useless, keep it at a default -47dBm for all neighbours. I don't think it is worth explaining it in details...
If you increase it towards a certain neighbour, you're going to reduce the number of HO from inner zone to that neighbour.
Please share your current settings.

|Hello Pix, I recently modified an existing single cell to concentric cell and traffic reduced, Level HO rate increased...Pls who can explain the reason.|
Also, what is this parameter "neighbour Rxlev(o,n)" used for and how is it tuned for concentric cells?

can any body tell me how i can know does my handset support DTM mode or Class A??

|Hi Xperts and Pix,|
I need to know about some Penalty time that we want to apply on certain Connections when they come from 3G to 2G . . . so that they don't go back to 3G instantly.

|hello, pls is it possible to declare two different carrier frequencies for a single antenna in 3G|
machine - 30th August 2010 (07:35 GMT)
|yes, after UTRAN command, and the HO access burst is sent, no synch occurs from the 2G side. I've chkd BSIC and BCCH, LAC, ID. all seems ok. Can I reset the RNC to align the clocks.|

|1. 2G to 3G HANDOVER is possible, we need to activate license (during dedicated mode), if on packet date, we called cell reselection.|
2. 3G to 2G HANDOVER when fail, check 2G side, same BSIC, 2G blocking
