I got a problem with HOs between some cells in a new ericsson BSC we recently intergrated.
All HO failures we get are due to PROTOCOL ERROR.
For some cells we cant even do cell reselection. the measurement reports C1 and C2 are invalid for neigbouring cells.
We have checked all C1 & C2 parameters are ok, Neihbour relations are defined together with MFs.
Please help as this has increased dropped calls & congestion on some cells.
