Question about connecting OSMO-MSC to MME from Open5Gs
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.
