Handover reversion

How to reduce high HO reversion between co-site cells? Vendor is E*******.
Pls, help! What to do with parameters? BCCH frequencies are OK.

bello is process to do that

Possible Reasons Trouble shooting
Up-link Interference in target cell Check drop call reasons for target cell.
Check handover reasons for target cell.
Run MRR measurement report
Check ICM in target cell.
Spectrum analyzer required to check external interference source
DL Interference in serving cell: The MS cannot detect the handover command message.
Check drop call reason for serving cell.
Check handover reasons for serving cell.
Run MRR
Check frequency plan.
Unbalanced Power link budget: Down-link is stronger than up-link in target cell.
Too high BTS output power.
Too low MS power setting.
Run MRR to check power balance, Important step to check the Path loss difference between UL and DL.
Lower power on TCH than on BCCH in target Cell Check power parameter setting.
Check BTS error log., Very Important Step to be checked.
Co-BCCH/BSIC in two n-cells: Run consistency check in OSS.
