Name Description
OsmoGGSN (former OpenGGSN)

OsmoGGSN is an Open Source implementation of a GGSN (Gateway GPRS Support Node). It is the successor to OpenGGSN and provides a Gp (GTP v0/v1) interface towards SGSNs like OsmoSGSN and a Gi interface towards the IP network. It supports Linux kernel GTP-U acceleration via a linux-kernel-gtp-u....

OsmoDia2GSUP

The Diameter to GSUP (HLR) adapter (OsmoDia2GSUP) enables you to connect osmo-hlr to a 4G MME. It speaks GSUP with osmo-hlr and Diameter/S6a with the MME (hence the name).

OsmocomTETRA

This project aims at practical research and experimentation with the TETRA trunked radio system. See OsmocomTETRA.

OsmocomLCS

This project contains proof-of-concept code to send GPS assistance data to mobile phones using RRLP (Radio Resource Location Protocol) as well as inquiring/obtaining their geolocation using RRLP queries. It uses OsmoNITB to operate the GSM network, and a u-blox GPS receiver to obtain the assistance data....

OsmocomGMR

This is the homepage of the Osmocom sub-project GEO Mobile Radio.

OsmocomDECT

[old, abandoned] OsmocomDECT project by Patrick McHardy, implements a linux kernel based DECT stack.

OsmocomBB SDR PHY

Up to now there was no software defined GSM mobile phone. The "SDR PHY for Osmocom BB" project aims to fill this void. The project is focused on the client side of GSM protocol stack, and bridging the gap between existing GSM stack implementation project and SDR hardware....

OsmocomBB

OsmocomBB is an Free Software / Open Source GSM Baseband software implementation. It intends to completely replace the need for a proprietary GSM baseband software.

Osmocom Libraries

This is about a set of shared C programming libraries the Osmocom project develops+maintains, such as libosmocore, libosmovty, libosmo-abis, libosmo-netif, etc.

Osmocom Conferences (OsmoDevCon, OsmoCon, OsmoDevCall)

The Osmcoom [Developer] Conference, an annual event where Osmocom Developers and Users gather

Osmocom Analog

This is a project implementing the analog cellular systems used in Germany and other countries in the past. It provides base station implementation of A-Netz (German pre-cellular), B-Netz (German pre-cellular), C-Netz (German cellular), NMT (Scandinavian: Nordisk Mobil Telefon) and AMPS/TACS (American: Advanced Mobile Phone Service)....

OsmoCBC

Osmocom Cell Broadcast Centre (CBC). It is the heart of the Cell Broadcast Service (CBS) as well as a variety of disaster/emergency warning systems (PWS).
OsmoCBC provides a REST/JSON interface for receiving cell broadcast messages from external entities and a 3GPP CBSP interface towards BSCs like OsmoBSC. Soon to be extended with SABP support towards RNCs....

OsmoBTS

OsmoBTS is an Open Source GSM BTS (Base Transceiver Station) with A-bis/IP interface. It implements support for a variety of PHY/Hardware, such as sysmocom sysmoBTS, OCTSDR-2G and LiteCell 1.5, but also general-purpose SDR boards such as USRP or LimeSDR via OsmoTRX....

OsmoBSCNAT

OsmoBSCNAT is an A-interface aggregator that can aggregate many A-interface links from many BSCs and present them as one A interface towards a MSC. Most normal networks will not need this component, it only serves some special use case scenarios. It requires SCCPLite and doesn't work with 3GPP AoIP....

OsmoBSC

OsmoBSC is an Open Source BSC (GSM Base Station Controller) with A-bis/IP and A/IP interface. It supports a variety of BTS Vendors/Models, including some Siemens, Nokia, Ericsson and ip.access models. However, main focus during the last 5+ years is OsmoBTS based BTSs....

osmo-uecups
osmo-sip-connector

This is the modern gateway between the MNCC Interface of OsmoMSC and OsmoNITB and an external SIP trunk. It converts between GSM TS 44.007 MNCC primitives on the one hand side and SIP messages on the other, while also signaling the RTP IP/port parameters for the voice user plane....

osmo-sim-auth
osmo-rfds

RF delay simulator using the ADI Pluto SDR

osmo-remsim

osmo-remsim is the Remote SIM software suite used to manage a set of phones/modems and a set of SIM/banks as well as the dynamic mappings of SIM cards to their remote phones/modems.

It consists of:
  • osmo-remsim-client: physically emulate SIM card at modem/phone using SIMtrace2 cardem or sysmoQMOD...
osmo-qcdiag

Osmocom tool for Qualcomm DIAG

osmo-pcap

Osmocom PCAP utilities, such as a distributed client/server capture architecture. It allows a number of PCAP probes on remote hosts, feeding captured packets to a central host in the network. Each probe can have different capture filters. There are multiple options for the protocol between probe and central host....

osmo-modbus

This project targets a C-Language library providing an implementation and interface to manage a Modbus node in a Modbus bus.

This library relies heavily on libosmocore library and it is aimed at being used by applications using that same library.

The Modbus specs can be found here: https://www.modbus.org/specs.php...

osmo-lab-rack

Various modules for building lab/testing setups using an industry-standard 3U component carrier

osmo-isdntap

A small program used to tap an E1 PRI line and obtain GSMTAP traces of the D channel as well as raw files with B channel content of each direction of each call.
