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, the sysmoBTS, the UmSITE, or the SDR based hardware with OsmoTRX.

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

osmocom.org server outage

For about one week from March 20, 2013 on most of the osmocom.org severs and services have been offline due to a hardware failure in the physical machine that was hosting all the virtual machines related to the project.

As I was on extensive business related travel, I couldn't go to the data center and take care of fixing the problem myself. So ...

osmo-pcu (GPRS Packet Control Unit) v0.1 released

After months of work by Ivan Kluchnikov and Andreas Eversberg, the Osmocom GPRS Packet Control Unit (PCU) has finally reached a point where it makes sense to release a first version: v0.1

There are still a number of limitations and shortcomings, most of which should be indicated in the wiki at osmo-pcu. However, even without hand-over, t ...

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 SIMtrace protocol tracer/sniffer for (U)SIM APDUs.
