4 | |||
5 | 6 | laforge | This is a project aiming to create a Free Software, (A)GPL-licensed software implementations for the GSM/3GPP protocol stacks and network elements. |
6 | |||
7 | We had originally started with an A-bis (plus BSC/MSC/HLR) implementation for experimentation and research purpose (now called [[OpenBSC:]], but have since moved way beyond that. |
||
8 | |||
9 | |||
10 | |||
11 | 9 | laforge | 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. |
12 | 6 | laforge | |
13 | 9 | laforge | [[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). |
14 | 6 | laforge | |
15 | In addition, the Osmocom project also develops and maintains the [[OsmoPCU:]], [[OsmoSGSN:]] and [[OpenGGSN:]] programs for adding GPRS/EDGE capabilities. |
||
16 | |||
17 | 11 | laforge | We have started with the Siemens BS11 microBTS, mainly targetted the ip.access nanoBTS for some years, but has since been extended to support a variety of other [[BTS]] equipment like the Ericsson RBS 2000 family. Today, most of the users and active developers work not with proprietary BTSs, but with BTSs running our [[OsmoBTS:]] software, i.e. either the "sysmoBTS":http://www.sysmocom.de/products/sysmobts family of hardware or SDR based hardware with [[OsmoTRX:]] like the "UmSITE":https://fairwaves.co/wp/products/. |
18 | 6 | laforge | |
19 | _We are always looking for [[HardwareDonations]] of any kind of GSM / 3G related carrier equipment._ |
||
20 | |||
21 | 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":http://simtrace.osmocom.org/ protocol tracer/sniffer for (U)SIM APDUs. |
