openbsc

An implementation of the minimal subset of the major backend
components of a GSM network, such as BSC, MSC, HLR, EIR. Using a
commercial GSM BTS and attaching it to a Linux system running the
OpenBSC software allows you to run your own GSM "network in a box".
OsmoBSC can run in one of two modes:

as OsmoBSC, exposing an A interface towards an external MSC, or
as OsmoNITB (Network In The Box), which implements a minimal subset
of the BSC, MSC. SMSC and HLR
