6 | Serving GPRS Support Node (SGSN). As such it implements the GPRS Mobility Management (GMM) and SM (Session Management). |
||
7 | |||
8 | 18 | laforge | The SGSN implements |
9 | * the Gb interface to the BSS's (like the [[OsmoPCU:]] or an ip.access [[OpenBSC:nanoBTS]]) |
||
10 | * the Gp interface with its GTP protocol to one or more Gateway GPRS Support Node (GGSN) like [[OpenGGSN:OsmoGGSN]]. |
||
11 | 27 | nickvsnetworking | * the IuPS interface with its RANAP protocol to one or more RNCs or HNB-GWs like [[OsmoHNBGW:]] |
12 | 20 | laforge | * the [[cellular-infrastructure:GSUP]] Interface/Protocol towards [[OsmoHLR:]] |
13 | 1 | laforge | |
14 | 28 | laforge | [[OsmoSGSN:]] is available from the https://gitea.osmocom.org/cellular-infrastructure/osmo-sgsn repository. In order to build it, you will need a libgtp installation from the [[OpenGGSN:OsmoGGSN]] project. |
