Ans:
Reasons for the HO reversion are
1) Co-Bsic and BCCH combinations are there in network so this type of problems occurs.
2)May be some issues in Target cells like Path imbalance.
3)Improper HO parameter settings.
4)Wrong Neighbour definition..
5) Interference on the target cell

Q: What is handover Reversion
Ans:
1. HO COMMAND is received by the MS
2. HO ACCESS is sent to the target cell
3. but no answer from the target cell.
After a while (timer expiry), the MS will try to go back to previous cell.
If reversion succesful, then there is a ho failure without drop
If reversion failed, then there is a ho failure with drop.
