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 (like the OsmoPCU or an ip.access nanoBTS), and it connects via the GTP protocol
to a Gateway GPRS Support Node (GGSN) like OsmoGGSN.

OsmoSGSN is available from the http://git.osmocom.org/osmo-sgsn/ repository. In order to build it, you will need a libgtp installation from the
OsmoGGSN project.
