||
| 7 | 1 | laforge | Serving GPRS Support Node (SGSN). As such it implements the GPRS Mobility Management (GMM) and SM (Session Management). |
| 8 | |||
| 9 | 7 | laforge | 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 |
| 10 | to a Gateway GPRS Support Node (GGSN) like [[OpenGGSN]]. |
||
| 11 | 1 | laforge | |
| 12 | 7 | laforge | [[OsmoSGSN]] is part of the openbsc git repository. In order to build it, you will need a libgtp installation from the |
| 13 | [[OpenGGSN]] project. |
