Hi Lilly,
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.
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-ms…
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.
Best,
lynxis
