| 4 | 7 | laforge | |
| 5 | 1 | laforge | Serving GPRS Support Node (SGSN). As such it implements the GPRS Mobility Management (GMM) and SM (Session Management). |
| 6 | |||
| 7 | 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 |
| 8 | 11 | laforge | to a Gateway GPRS Support Node (GGSN) like [[OpenGGSN:]]. |
| 9 | 1 | laforge | |
| 10 | 11 | laforge | [[OsmoSGSN:]] is part of the openbsc git repository. In order to build it, you will need a libgtp installation from the |
| 11 | [[OpenGGSN:]] project. |
