IMPORTANT NOTICE: This page contains information about a legacy version of the Osmocom software. This legacy version is no longer maintained. If you use it, don't be surprised if it doesn't work. It was your choice to ignore man-years worth of developments, improvements and fixes. Please migrate to the active/supported software (Osmocom CNI, consisting of OsmoBSC, OsmoMSC, OsmoHLR, OsmoSTP, OsmoMGW - a NITB style setup is described at Osmocom_Network_In_The_Box).

- Welcome to Osmocom OpenBSC
- Overview Diagram
We have started with an A-bis (plus BSC/MSC/HLR) implementation for experimentation and research purpose, but have since moved way beyond that.
What this means: OpenBSC is not just a standard BSC, but a GSM network in a box software, implementing the minimal necessary parts to build a small, self-contained GSM network.
OpenBSC includes functionality normally performed by the following components of a GSM network: BSC (Base Station Controller), MSC (Mobile Switching Center), HLR (Home Location Register), AuC (Authentication Center), VLR (Visitor Location Register), EIR (Equipment Identity Register).
We have started with the Siemens BS11 microBTS, mainly targetted the ip.access nanoBTS for some years, but has since been extended to support a variety of other BTS equipment like the Ericsson RBS 2000 family. Today, most of the users and active developers work not with proprietary BTSs, but with BTSs running our OsmoBTS software, i.e. either the sysmoBTS family of hardware or SDR based hardware with OsmoTRX like the UmTRX or UmSITE.
We are always looking for HardwareDonations of any kind of GSM / 3G related carrier equipment.
Please see the below overview diagram about common possible configurations of the Osmocom software.

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.

- OpenBSC was running an experimental GSM network at CCC Camp in the Summer of 2011
- OpenBSC was running an experimental GSM network at 27c3 in December 2010
