9 | 1 | laforge | Serving GPRS Support Node (SGSN). As such it implements the GPRS Mobility Management (GMM) and SM (Session Management). |
10 | |||
11 | 10 | laforge | The SGSN connects via the Gb-Interface to the BSS (like the [[OsmoPCU:]] or an ip.access [[OpenBSC:nanoBTS]]), and it connects via the GTP protocol |
12 | 16 | laforge | to a Gateway GPRS Support Node (GGSN) like [[OpenGGSN:OsmoGGSN]]. |
13 | 1 | laforge | |
14 | 16 | laforge | [[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 |
15 | [[OpenGGSN:OsmoGGSN]] project. |
