Welcome to Osmocom OpenBSC

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 osmo-sgsn and 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 BTS equipment like the Ericsson RBS 2000 family or the upcoming sysmoBTS.

We are always looking for HardwareDonations of any kind of GSM / 3G related carrier equipment.

Introducing the Osmocom Continous Integration Setup

The Osmocom project has gained a Jenkins setup that will build the various parts of Osmocom after each change. As part of this setup we have enabled automatically executing tests in libosmocore as part of the make distcheck command, it has been extended to the cellmgr_ng and hopefully will be used ...

Announcing libosmo-abis

We have finally split the low-level A-bis access routines into a separate library called libosmo-abis. This allows us to re-use the code in a variety of projects outside OpenBSC, such as OsmoBTS.

However, this also means there is now one additional dependency that you need in order to build OpenBSC. However, it shou ...

Introducing doxygen-generated API documentation

For quite some time there has been a distinct lack of API documentation regarding the various Osmocom sub-projects.

Starting with libosmocore/libosmogsm, we are introducing doxygen-generated API reference documentation. You can see the first results at the following pages:

Introducing the osmo-bts project

For quite some time we've been hacking away on a project called osmo-bts.

You can find it source code as usual on git.osmocom.org, for occasional web browsing we offer cgit access.

osmo-bts is a BTS-side Layer3 and Layer2 protocol implementation, including Abis/IP, TS 08.58 RSL, TS 12.21 OML, TS 04.0 ...

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