Welcome to OpenBSC

Welcome to 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 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).

Right now we are targeting the Siemens BS11 microBTS and ip.access nanoBTS GSM base transceiver station, but we are planning to support different BTS equipment in the future.

We are 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 ...
