{{>toc}} h1. [[OsmoSGSN:]] Contact us via the osmocom-net-gprs@ mailing list, see [[Cellular Infrastructure:Mailing Lists]]. Contributions are welcome via [[Cellular Infrastructure:Gerrit]]. Git repository browser at https://git.osmocom.org/osmo-sgsn 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 [[OsmoPCU:]] or an ip.access [[OpenBSC:nanoBTS]]), and it connects via the GTP protocol to a Gateway GPRS Support Node (GGSN) like [[OpenGGSN:OsmoGGSN]]. [[OpenGGSN:]]. [[OsmoSGSN:]] is available from part of the http://git.osmocom.org/osmo-sgsn/ openbsc git repository. In order to build it, you will need a libgtp installation from the [[OpenGGSN:OsmoGGSN]] [[OpenGGSN:]] project. h2.
