PageOutline = Welcome to Osmocom OpenBSC =

This is a project aiming to create a Free Software, (A)GPL-licensed software implementations for the GSM/3GPP protocol stacks and elements.

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).

In addition, the Osmocom project also develops and maintains the [wiki:osmo-sgsn] and [wiki:OpenGGSN] programs for adding GPRS/EDGE capabilities.

We have started with the '''Siemens BS11 microBTS''', mainly targetted the '''ip.access nanoBTS''' for some years, but we are also working on a variety of other [wiki:BTS] equipment like the Ericsson RBS 2000 family, the [http://www.sysmocom.de/products/sysmobts sysmoBTS], the [https://fairwaves.co/wp/products/ UmSITE], or the SDR based hardware with [wiki:OsmoTRX].

''We are always looking for [wiki:HardwareDonations] of any kind of GSM / 3G related carrier equipment.''

There is also continued work on creating a Free Software / Open Source sUnderstandingOpenBSCrteoftware SS7 (M3UA, SUA, SCCP, TCAP, MAP) protocol stack in Erlang, as well as a number of other side projects like the [http://simtrace.osmocom.org/ SIMtrace] protocol tracer/sniffer for (U)SIM APDUs.
