Hi all, my current task is implementing inter-MSC Handover for OsmoMSC. It would be immensely helpful to look at network traces of the messages carrying out an inter-MSC handover. Primarily for 2G (BSSAP), but 3G (RANAP) might also be interesting. The part on the A-interface (BSSAP) is interesting for both the outgoing (orig. MSC and BSS) as well as the incoming (remote MSC and BSS) sides. Most interesting would be some kind of trace of communication between the two MSCs, the E-interface (MAP) negotiating the HO as well as the call forwarding between the two MSCs, if at all available. We are exploring various avenues to obtain inter-MSC HO traces, so far to no avail. If anyone reading this is able to help out, that would be highly appreciated and super helpful to be interoperable.
