Osmocom Serving GPRS Support Node
This is an 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 (like the osmo-pcu or an ip.access nanoBTS), and it connects via the GTP protocol to a Gateway GPRS Support Node (GGSN) like openggsn.
