yes, it’s what bilal said : it will NEVER happens. We all agree here.
in the co-BCCH/co-BSIC situation i described in my previous post, it will lead to a HO failure, certainly with a reversion to previous TCH channel. So, no drop.
So problem of HO failure as reported in TEMS :
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.
