Hello everybody,
I was trying to setup an OSMO-MSC with an Open5Gs-Corenetwork, so I can send SMS to different UEs. Unfortunately the OSMO-MSC does not connect to the MME of the Open5Gs-Core and I do not find any installation guide for this specific setup.
For your information: The Open5Gs-Core runs on a Laptop and I build the Software from source (4G and 5G components). The MSC should run on the same Laptop.
Therefore I would like to ask you, if you can tell me, which other components besides of the OSMO-MSC I possibly have to install and how I should configure this components and the components of the core.
Many thanks in advance!
Best regards
Lilly Hennig
Hi Lilly,

the osmo-msc and open5gs-mmed communicates via sgs. On the open5gs side you can find an example confiugration on Supreeth Herle' docker repos: - https://github.com/herlesupreeth/docker_open5gs/blob/master/mme/mme.yaml
The important part is to map tai's to a lai's. Additional you need to enable sgs on the osmo-msc:
``` sgs local-ip 127.0.0.9 local-port 29118 vlr-name vlr.THREEGPP_REALM ```
- https://github.com/herlesupreeth/docker_open5gs/blob/master/osmomsc/osmo-msc...
You also need to setup an osmo-hlr and have at least the IMSIs of the subscriber added to the osmo-hlr's database. Currently there is no way to connect the osmo-msc to the open5gs-hss.
