Cannot HO to neighbour cells !

[iCloud]

Hi Bro
Pls help me for this problem:
We've just onair new-site, but when doing DT, MS only HO between sectors, cannot HO to neighbour cells:
- Check NBLs, OK
- No alarms about transmission, WSR, check hardware ( power, installing ) OK
- Change control Card ( SUMA, Alcatel BTS ).
- Delete all parameters and configure again
- Synchronous OK
Can anybody give me another solutions for this ?
Many tks for ur supports

Hello,,

Please check the neighbor list of the existing neighbor sites,, maybe the new site is not defined as neighbor that is why there is no hand over,
in short please check your neighbor list parameters

Hi

1)Is the same HO not happening to a particular sector or for all inter cells.
-if above is true then check wether inter HO is disabled for site.

2)Else Compare the problamatic defnition with other relations.

Hi mate

HO can be done between sectors, but cannot HO to neighbour
In KPI calculation, HOSR is ok. But when doing Driving Test, we cannot handover to another cells

Check also the adjacent neighbour cell frequency,, example for wimax tech...if they have the same frequency it will not handover

I face similar issue before. We found out the mismatch of Clock. One of New Site does not have standard clock so there were issues of incoming/outgoing handovers. If you can check, clock freq. of site by OSS or by using Freq. Meter than you can conclude something. Other way is that you can put clock of site in Free Running mode. Add thanks & reputation if you find it useful.
