I’m not clear about what you said.Could you explain a bit more alongwith what things have you checked?
Bijoy17th May 2012 at 15:27 #62565AghaGuest
yes sure, let’s assume 2 cells of different sites but neigbor, cell A and cell B have low HSR Moreover DCR of cell A is also increased with increased of N200 drops increased.No hardware/Interference issue.whats the issue with HSR and what i hv to check?18th May 2012 at 05:33 #62566BijoyGuest
Is it that the HOSR of CELLA to Cell B is poor & vice-versa?For rest Cells,the HOSR of Cell A is OK.
Did I get it r8?
Bijoy18th May 2012 at 07:03 #62567AghaGuest
yes bijoy,only Cell A to Cell B HOSR is degraded and not vice versa and all HO from this culprit cells to other cells are fine.
Thanks.18th May 2012 at 08:29 #62568BijoyGuest
Pls check the following
1.CO_BSIC-BCCH in vicinity of Cell A & Cell B.
2.HO parameters of Cell A to Cell B definition & vice-versa.
3.Try delete-create the neighbor definitions,both way.

Thanks for reply.
i have check point 1 and 2 and no discrepancy found.on checking MAL clash was observed since from last 02 months and after correction issue resolved,but this low HOSR issue appeared from last 06 days.19th May 2012 at 06:18 #62570pixGuest
A->B : bad HOSR
A->x : good
what about any other cells towards B:
y->B : ?
* how many HO requests from A->B
* how many HO requests from A->A’s best neighbour ?
* what is the cause of HO from A->B, if you can know it?
* does this adjaceny really should generate so many HO?
* how many HO Requests from B->A?
* how many TRX in cell B?
* what about TCH assignment failure rate in cell B (during call setup), what value is it?
As said bijoy, don’t forget to delete/recreate the adjacency, that might work.

yes thanks alot Bijoy/Pix. issue is resolved after MAL correction.
I have post a reply but its not posted, i do not no why??24th May 2012 at 20:59 #62573AghaGuest
first both sites lies in totally remote region and just neighbor to each other.below is yr req:
*y->B::HOSR greater than 97%(Y is the cell of same site as of cell A)
*HO requests from A->B::Avg 750(on Day level).
*HO requests from A->A’s best neighbour:: 750(As it is the only neighbor)
*cause of HO from A->B::H371F HO commands due to Better cell and H371C HO commands due to Uplink strength,
* 10 TRX’s and no Blocking.
*Yes TCH ASR follow the same trend as HOFR.
And please also define(H371L outgoing HO commands due to other causes,what is other causes).
Equip. is Huawei.25th May 2012 at 06:06 #62574BijoyGuest
Seems the ghost of MAL frequencies has not left you n/w
Bijoy27th May 2012 at 14:12 #62575AghaGuest
that is RF:)
and plz explain
(H371L outgoing HO commands due to other causes),what is other causes.29th May 2012 at 05:46 #62576AghaGuest
Awaited for ur response,plz.
