OsmoSGSN (also spelled {{{osmo-sgsn}}} when referring to the program name) is a Free Software implementation of the GPRS
Serving GPRS Support Node (SGSN). As such it implements the GPRS Mobility Management (GMM) and SM (Session Management).
The SGSN connects via the Gb-Interface to the BSS (e.g. the ip.access nanoBTS), and it connects via the GTP protocol
to a Gateway GPRS Support Node (GGSN) like [wiki:OpenGGSN].
It is currently very experimental. The Gb protocol stack and the LLC implementation are quite robust, and signalling
for GMM and SM seems to run pretty fine. However, the user plane including SNDCP fragmentation is in pre-alpha quality.
OsmoSGSN is part of the openbsc git repository. In order to build it, you will need a libgtp installation from the
OpenGGSN project.
