Hi Do you know if the packet osmo-smlc should work with osmo-bsc, osmo-stp last versions?
I just tested, saw errors and tried to debug but perhaps I made mistakes (link, as, asp are up between BSC and SMLC via osmo-stp)
osmo-smlc 0.2.4
DLSCCP DEBUG <0011> sccp_user.c:176 Delivering N-PCSTATE.indication to SCCP User 'SCCP Management' DLSCCP DEBUG <0011> sccp_scmg.c:298 Ignoring SCCP user primitive N-PCSTATE.indication DLSCCP DEBUG <0011> sccp_user.c:176 Delivering N-PCSTATE.indication to SCCP User 'OsmoSMLC-Lb' DLB ERROR <0002> sccp_lb_inst.c:167 (Lb) sccp_lb_sap_up(N-PCSTATE.indication) unsupported
Many thanks in advance Best regards Jean-Marc

These are not critical errors, PCSTATE just notifies of SCTP point-codes becoming available or unavailable. We ignore those messages in osmo-smlc.
It would be interesting to know what you are planning to achieve with osmo-smlc -- it is not particularly capable yet...

Hi Neels Many thanks for your answer. "it is not particularly capable yet..." is not the expected answer... We hoped that the SMLC was operational.
We would like to know if the OSMO-SMLC could answer to a GMLC (SLIR sent by an SLC client) To detail, Do you know if the OSMO-BSC could answer to an MSC sending a BSSAP Perform Location Request ? Do you know if the OSMO-SMLC could answer to a Location Request Procedure (OSMO-BSC sending a BSMAP-LE Perform Location Request ? Do you know if the OSMO-SMLC knows how to send a TA (Timing Advance) position Procedure (OSMO-SMLC sending a BSMAP-LE Connection Oriented Information) ?
Do you know if some people are still working on SMLC?
Best regards Jean-Marc

Yes, osmo-smlc can return a GAD sphere based on cell ID and TA, and does so when the MSC asks for a BSSAP Perform Location Request. That part works fine.
I find that not very exciting, because the BSC already knows that information, and all that osmo-smlc does is convert the configured cell id location and the TA to a GAD PDU. Obtaining it via Lb/BSSMAP-LE seems to be a mere formality.
Of course if that's sufficient for you, osmo-smlc is very capable =)

We're currently not having particular plans, but osmo-smlc is part of our CNI software and actively supported; in the sense that we build binary packages, have an issue tracker and will review and accept patches. Ready when you are.
