OsmoBSC

OsmoBSC is an implementation of a GSM BSC (Base Station Controller), i.e. it offers
  • an A-bis interface towards the BTSs
  • an A-over-IP (AoIP) interface towards an MSC (e.g. OsmoMSC).

History / Naming / SCCPlite

Until 2017, we used to have an osmo-bsc part of the old openbsc.git repository which implemented a smaller sub-set of the BSC functionality with an SCCPLite based A interface. This legacy program is now called osmo-bsc-sccplite and continues to be available for legacy users. However, it is not actively developed anymore.

BTS Support

OsmoBSC supports currently all BTSs running the OsmoBTS software (such as sysmoBTS), as well as ip.access nanoBTS devices. Other Abis/IP devices may be supported.

Support for legacy E1/T1 TDM based BTSs (like those supported by OsmoNITB is on the roadmap.

Binary Packages

Osmocom provides binary packages for several flavors of Debian and Ubuntu GNU/Linux on a variety of architectures (i586, x86_64, armhf, armv7l). Unless you are a software developer interested in developing on Osmocom, it is recommended you use those packages instead of building from source.
