All our software is available in source code form, to anyone. This is very contrary to classic telecom vendors, where every network element is implemented as proprietary hardware and software, without the ability to understand or modify them, and where each and every feature is subject to license fees. 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 and implemented many other interfaces and network elements of GSM, GPRS, EDGE and UMTS/ HSPA networks. While previous installations mostly used OsmoNITB from the OpenBSC project as a monolithic core development has now shifted to individual projects performing the different tasks that were previously united inside the OsmoNITB, such as: * OsmoMSC - a GSM/UMTS Mobile Switching Center with support for AoIP as well as IuCS. SCCPlite support is work in progress * OsmoBSC - a GSM Base Station Controller with support for many different BTS vendors and models attached via Abis (over E1 and IP). * OsmoSTP - a SS7 Transfer Point to connect MSC and BSC * OsmoHLR - a minimal implementation of a Home Location Register * OsmoMGW - Media GateWay to relay RTP streams This is more in line with the way a traditional GSM network is operated. The actual radio interface of such a network can be provided by classic GSM BTS equipment from classic Vendors like Siemens, Nokia, Ericsson, ip.access. However, a variety of more modern BTS options are available, based on our OsmoBTS software using hardware from sysmocom (sysmoBTS), Fairwaves (UmTRX) or Ettus (USRP) In addition, the Osmocom project also develops and maintains the OsmoPCU, OsmoSGSN and OsmoGGSN programs for adding GPRS and EDGE capabilities. Most recently, there is a project for adding 3G (UMTS, HSPA) support. Specifically, this is adding Iu-CS and Iu-PS support to OsmoMSC and OsmoSGSN, as well as a new OsmoHNBGW to offer an Iuh interface towards hNodeBs (femtocells, small cells) We are always looking for HardwareDonations of any kind of 2G / 3G / LTE related carrier equipment. There is also work on creating SS7 / SIGTRAN / TCAP / MAP protocol stacks, both in the Erlang programming language as well as in Smalltalk. There are many other side projects like the SIMtrace protocol tracer/ sniffer for (U)SIM APDUs. Overview DiagramP Please see the below overview diagram about common possible configurations of the Osmocom software. If you are overwhelmed by all the abbreviations, have a look at the glossary. New Getting startedP A self-contained setup with minimal config of your core network is described at Osmocom Network In The Box. For a more general overview of your options, take a look at the Configuration Guide. If you have an OsmoNITB installation and would like to move to separate OsmoMSC and OsmoBSC with the new M3UA SIGTRAN, see the OsmoNITB Migration Guide. SoftwareP Software for a Base Transceiver StationP * OsmoBTS -- A BTS implementation + OsmoTRX -- A transceiver for OsmoBTS to use with SDR hardware * OsmoPCU -- A packet control unit for GPRS/EDGE enabling the BTS. Software for running a full minimal GSM Network in a BoxP These circuit-switched (voice) related core network components can all run on the same box: * OsmoHLR * OsmoMSC * OsmoMGW * OsmoSTP * OsmoBSC They replace the old * OsmoNITB -- A stand-alone gsm-network-in-a-box program implementing minimal subset of BSC, MSC, HLR, AuC and EIR. Software for running in pure BSC only mode, attaching via A/SCCP to a MSCP * OsmoBSC -- OpenBSC in BSC-only mode (with external MSC) * osmo-bsc_mgcp -- A stupid MediaGatewayControlProtocol (MGCP) gateway for OsmoBSC Software for UMA/GAN (Unified Mobile Access)P * osmo-ganc -- OpenBSC in GANC mode Special purpose software for aggregating multiple A or Gb linksP * osmo-bscnat -- a BSC NAT/Multiplexer * osmo-gbproxy -- A proxy/gateway for aggregating multiple Gb links betwen BSS and SGSN * Testing -- Comments and what makes sense to test for releases GPRS/EDGE related softwareP * OsmoPCU -- A GPRS + EDGE RLC/MAC and PCU implementation to be used with OsmoBTS * OsmoSGSN -- A Serving GPRS Support Node * OsmoGGSN -- A Gateway GPRS Support Node There's also a tutorial at OpenBSC_GPRS explaining how to add data support to your OsmoNITB setup * Important legal information on SoftwareLicensing * meas_web -- Web based measurement utility for OpenBSC DevelopersP * Browse the repositories at https://git.osmocom.org/ * Mailinglists at https://lists.osmocom.org/mailman/listinfo/ * Jenkins (continuous integration) at https://jenkins.osmocom.org/ jenkins/ * Wiki is right here ;) * Developer conferences: OsmoDevCon * Tasks -- Tasks/Internships/Junior Jobs for OpenBSC and Osmocom * Devtools -- Various tools to find/fix errors, send patches, etc * Coding_standards -- Coding standards * Make a new release Commercial SupportP Commercial support as well as development, system integration and training services for this project are available from sysmocom Related projectsP * OsmocomBB - Free Software GSM protocol stack for mobile phones * OpenBTS:http://gnuradio.org/redmine/projects/gnuradio/wiki/ OpenBTS * The THC GSM project * airprobe.org * Homepage of Dr.-Ing.
