reasons for handover failure

[Tameem]

can any ony one tell me the reasons for HO failure.besides faulty hardware.
how can we find out if HO is failed due to congestion.can we analyze it through layer 3 messages

it could be due to congestion or interferance. and yes you can analyze it through layer 3 messages.

or it could be related to missing neighbour...you can find them if using Tems or nemo with a corect setted workspace...

Invariably, this is caused due to a missing neighbour...Analysis through Mapinfo is also helpful along with the OMC data...Also look at your handover parameters, CRO settings, in your OMC...

hi tameen,
you can analyze it through layer 3 messages (see request event).
- make sure that no miss relations in layer 1~2 and check site overshooting
- find out the status of target HO (congestion or not)
- check parameter and priority HO.
- check site position (rural/urban/suburban...etc),obstacle, and distance between source and target HO.


Btw, this for 2g or 3g?

It can be due to bad frequency and BSIC planning (BSIC confusion)

[arban]

one of the reason you can check is neighbour setting. That's always happen to me.

checl co-BSIC and CO-BCCH and layer 3 mesages

[stream19]

is not due to missing neighbor (we have HO in the cell already defined as neighbor)
