Reply To: Inter BSC HO failure

hi amit,

the first step is to check the QOS stats:
1/ are there HO REQ and HO SUCC between those 2 cells, over the last days ? Check hourly. Check both ways.

YES -> go to 2/
NO -> go to 3/

2/ Is the target cell congested ?

YES -> in such case, the incoming HO are rejected. Tune the target cell in order to reserve one or two timeslots for incoming HO.
NO -> got to 4/

3/ Are both cells in different BSC, or different LAC ?

YES -> Check the core network configuration
NO -> delete & recreate the relation

4/ You need to perform Ater traces and A traces in order to understand at which stage the HO doesn’t work.
