Thanks harald for the detailed response.
Unfortunately the testing scenario we want to try is to have a sperate MSC instance from
another vendor , hence we cannot use the Osmo MSC .
We have already tested the SG interworking between Amarisoft EPC and Osmo MSC,both MO/MT
CSFB SMS was working fine.

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.
Regards,
Harald
