We had a question with regards to the OSMO MSc - as per the documentation , it does support a scaled down version of SMSC.
Yes.
Can we bring up just the SMSc service so that it can talk to another vendor's MSC/HLR .
No, this is not possible. The OsmoMSC internal SMSC functionality doesn't implement any external/standard interfaces.
We are trying to perform CSFB SMS tests with an external MSC / OSMO SMSC and Amarisoft EPC Core . So wanted to check if the OSMO SMSC could be used for this test.
Unfortuantely not. However, you can of course use the Amarisoft SGs to talk to OsmoMSC SGs and support SMS services this way. You'd need OsmoMSC and OsmoHLR on the Osmocom side. You would not have any interworking with external HLRs.
As there is no DIAMETER support in OsmoHLR, you'd have to manually ensure that the same subscriber information (IMSI/K/OPc/...) is present in the Amarisoft HSS and the OsmoHLR.
Having a GSUP-to-DIAMETER gateway is on our wishlist, exactly to support scenarios like this: Use some 3rd party vendor EPC for 4G in parallel with the Osmocom stack for 2G/3G, both accessing one shared subscriber database. However, unfortuantely nobody has yet been able to dedicate any resources to this task.
