I did not work on this, but on the related GSUP messages (#3774). So I can't say what the status is here.

TTCN3 tests are implemented on branch neels/ho of osmo-ttcn3-hacks, need to be finalized and made ready to merge.
There is a slur of other ttcn3 patches that need to be applied before...
- The tests of successful HO were written when there was no MNCC forwarding yet. May need adjusting.
- The unsuccessful cases are obviously many more than the successful ones, so far only one or two exist.

Just for your information: I'll plan to read through + review that branch until Sunday.

(haven't yet changed the inter-BSC test to what we discussed, it is still segmented into two functions.
A lot of those commits need squashing, maybe i've done that by the time you're taking a look.)

An initial test for inter-MSC Handover is merged to osmo-ttcn3-hacks master.
However, the middle part of that test wants to play through some USSD signalling to test inter-MSC DTAP, which doesn't work because somehow the ttcn3 code to encode the messages is still wrong.
Also missing are failure cases of inter-MSC handover.

BTW, the test called TC_ho_inter_msc_out() of course also includes the incoming side as a Subsequent Handover back to the original MSC.
However, a separate test of handover towards an MSC-B (that does not also have the msc_a role) should be added as well.
