Osmocom CNI successfully integrated with Amarisoft eNodeB and EPC , interoperating with CSFB and SMS-over-SGs

sysmocom has successfully tested Circuit Switched Fallback (CSFB) and SMS-over-SGs interoperability of the Amarisoft eNodeB and EPC with the Osmocom CNI stack. CSFB and SMS-over-SGs support have been implemented in the Osmocom stack mainly by providing the SGs interface, which bridges the 4G MME to the 2G/3G MSC.

With CSFB and SMS-over-SGs it is now possible to operate 2/3/4G networks based on Amarisoft and Osmocom components. As both implementations have implemented SGs and CFSB based on 3GPP TS 29.118 and 3GPP TS 23.272, we are confident regarding interoperability with other CSFB components' vendors.
