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) ?
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 =)
Do you know if some people are still working on SMLC?
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.
