Feature #1993

osmo-hnbgw and libiu code of OsmoMSC and OsmoSGSN needs to be ported to libosmo-sigtran
Added by laforge about 7 years ago.
Updated over 6 years ago.
Description
The changes required in libosmo-sigtran to support AoIP require other users of libosmo-sigtran to be ported to the new API. Currently, this mans osmo-hnbgw as well as OsmoMSG and OsmoSGSN, who all use the Iu interface (currently over SUA, then over real M3UA).
- Related to Feature #1843: Add SCCP/M3UA signaling transport as alternative to IPA multiplex to osmo-bsc added
- Project changed from OpenBSC to OsmoHNBGW
- Target version deleted (
A-over-IP interface as per 3GPP)
- Status changed from New to In Progress
- % Done changed from 0 to 20
osmo-hnbgw was really simple, but I think there are some wrong design assumptions in libiu which make porting of the OsmoMSC and OsmoSGSN much harder. Each UE context should not store a reference to the SCCP Link, but to the remote SCCP Address. It doesn't matter from which physical link a message originates; it only matters from which SCCP CalledAddress it comes from. I'll investigate required architectural changes and modify it accordingly.

I have a version of osmo-hnbgw and osmo-msc that talk to each other on top of the current laforge/sigtran branch of libosmo-sccp via the new osmo-stp. This needs more testing + clean-up but I think it will be resolved soon.

I think this has been implemented by Neels, please double-check. At least I could build osmo-iuh master against libosmo-sigtran master right now, so I guess the porting has been done.

correct, osmo-iuh master is using libosmo-sccp master and the new SIGTRAN now, has been tested successfully with an actual nano3G and the new split-up osmo-{msc,bsc,mgw,sgsn}.git code state.
