10-19, 09:30–10:00 (Europe/Berlin), Conference Venue

Introducing the GSUP based external USSD interface of the Osmocom Core Network stack


In this talk Vadim will to share the state of external SS/USSD interface support in the Osmocom core-network stack. For many years there was the only one USSD-code (i.e. '*#100#'), that was used to get subscriber's extension.

Recent developments in OsmoMSC and OsmoHLR have made it possible to connect an external USSD gateway, and handle USSD-sessions outside the Osmocom stack.
