Feature #2487
MSC side of LCLS (local call local switching) as per the 3GPP specs
20%
Description
3GPP LCLS allows the media stream of a call to remain locally at the BTS, if both legs of a call are within the same BTS. We should implement this in OsmoMSC, if not only to test the OsmoBSC side which we want to implement, too.
Checklist
- LCLS implementation in OsmoMSC
- test suite for LCLS in MSC
- jenkins integration of test suite

Shall I take this as well? Seems like next logical step to be able to test LCLS with actual hw.

Corresponding libosmocore changes are mostly merged, there're 4 more pending patches for OsmoMSC.
N. B: current implementation is only suitable for testing due to issues with CallRef handling by transactions. This part is going to be heavily changed by intra-BSC handover work.

Experimental implementation available in:
https://gerrit.osmocom.org/c/osmo-msc/+/13421/
https://gerrit.osmocom.org/c/osmo-msc/+/11746/
https://gerrit.osmocom.org/c/osmo-msc/+/13422/
It's already useful enough for testing BSC-side but needs more work to properly handle HO and correctly construct GCR for all interfaces/transaction variants.
