Reply To: Invalid Cell in BSSMAP HO message


You could also have a neighbour audit (external + internal) of the source cell on which attempts are being generated.
It might be a case where you have defined a far off neigbour but missed a nearby neighbour due to BCCH/ BSIC clash and MS measures this BCCH/BSIC (of the nearby cell not defined) and attempts on the far off cell. Which fails as MS cannot camp.
