Description

Right now we can only do intra-BTS and intra-BSC hand-over. The networks that we needed to support were happy with that.

Hoewever, for larger networks that use multiple OsmoBSC attached to one MSC, inter-BSC handover is required.

(While working out test scenarios for the MSC I had to go through the Handover topic too)

The attached file messages.txt contains, what I think is the minimal information that we have to exchange in order to perform an external handover. The messages in the order in which they were exchanged between BSC1, BSC2 and MSC. Most things seem to be pretty clear to me. However there are some open questions (see questionmarks). I think it will not make much sense to develop this on a laboratory setup since the things will get way to complicated then. We should go for TTCN3 here and do only the final tests with real base stations.
