osmo-hnbgw and libiu code of OsmoMSC and OsmoSGSN needs to be ported to libosmo-sigtran
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).
- 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.
