= Welcome to BS11-Abis / OpenBSC =

This is a project aiming to create a Free Software, GPL-licensed Abis (plus BSC/MSC/HLR) implementation for experimentation and research purpose.

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 [wiki:BTS] equipment in the future.
