as for OpenBTS handover, I studied OpenBSC code.
I'm issuing exactly the same handover command, even including the sequence of fields, not only values :)

I'm waiting for the second umTXR back to continue investigating..

If this is done inside of the OpenBSC, it should be easy to hack a VTY
command to force handover. It may be a useful command as well, if you
want to do load balancing of your network. Am I missing something?
