The official Osmocom binary packages will not be built anymore for the following distributions starting at 2024-02:
- Raspberry Pi OS 64-bit (use Debian_12 etc. instead)
- Ubuntu 23.04 (Ubuntu 23.10 and LTS 20.04/22.04 feeds are available)
- openSUSE 15.4 (openSUSE Tumbleweed feed is available)
- Debian Testing (Debian Unstable and 12-10 feeds are available)
For Raspberry Pi OS 64-bit users, make sure to adjust your /etc/apt/sources.list.d as described here to switch to a Debian aarch64 feed.
See the new linux distributions article for information on how long we plan to keep building packages for each distribution.
The Osmocom project has released new version 202309 of the CNI (Cellular Network Infrastructure) software, including OsmoTRX, OsmoBTS, OsmoPCU, OsmoBSC, OsmoMGW, OsmoMSC, OsmoHLR, OsmoSGSN, OsmoGGSN, OsmoSTP, OsmoSIPConnector, and others.
Those new tagged/released versions contain 7 months of work since the previous versions released during mid February 2023.
You can find pre-compiled binary packages of our latest release for a variety of Debian and Ubuntu GNU/Linux versions at Latest_Builds.
The main areas of work since the previous releases are:
- Support of Circuit Switched Data (CSD) calls in 2G
- Support of Advanced Speech Call Items (ASCI) for Voice Group + Broadcast Calls in GSM-R
- Support of more authentication algorithms (XOR-2G, TUAK)
- Massive improvements in handling of voice codec negotiation
- Support for GPRS on Ericsson BTSs with E1/T1 TDM back-haul
- much more low-level control over the SCTP stack underneath libosmo-sigtran/osmo-stp
- performance optimizations of OsmoBSC

After months of work (primarily by dexter), we're happy to have finally merged code into OsmoBSC to support GPRS/EGPRS on the Ericsson_RBS family of cellular base stations.
This means that [inexpensive] decommissioned Ericsson RBS6000 hardware (as described in Minimal_RBS_Assemblies can now not only be used for providing classic circuit-switched GSM services, but also to provide GPRS/EGPRS services.
Development of this work was made possible by yet another grant from the NLnet foundation (see also https://nlnet.nl/project/Osmocom-RBS/).
The majority of the related code lives in the OsmoBSC and OsmoPCU projects, together with libosmocore and libosmo-abis. OsmoBSC now provides a PCU socket interface (like OsmoBTS does in our normal BTS-colocated PCU), and OsmoPCU can directly open the E1 tieslots for the PDCH channels (similar to how OsmoMGW handles voice channels in E1 based BTS).
For a list of relevant commits, see https://gerrit.osmocom.org/q/topic:e1_gprs
Updates to the user manual and wiki (e.g. Ericsson_RBS2000_GPRS) should follow shortly. If you're curious to try it, you can find an example file at source:doc/examples/osmo-bsc/ericsson/osmo-bsc.dug20-rus02-1trx-1pdch-16kbps.cfg
The code has so far only been tested in our lab. Your mileage my vary. If you do try it, please feel free to report any issues you may find.
We're happy to announce that sysmocom has achieved to obtain funding from Open Technology Fund for a variety of enhancements and improvemnts of the Open Source Cellular Network Infrastructure sphere.
The funded activities are in the following areas:
- Better integration between the Osmocom 2G/3G core network elements and the open5gs 4G EPC (evolved packet core)
- Improving the stability, quality and maturity of the open5gs EPC by implementing functional test suites in TTCN-3
- Establishing interoperability with various base station hardware
- Support three trial deployments in rural Mexico with our partner Rhizomatica
- Organize a series of webinars for security researchers on how to use our tools for furthering their research projects
See also the project description at the OpenTechFund website
We'd like to thank OTF awarding funding to our proposal.
We'd also like to thank Rhizomatica and specifically Peter Bloom for all his help in putting together the proposal.
The nightly and latest feeds of the Osmocom binary packages for Debian, Raspbian, Ubuntu, openSUSE and CentOS are from now on available at downloads.osmocom.org. See the binary packages wiki page for the exact, distribution specific URLs and for instructions for adding the repositories in these distributions.
As transitional phase, the packages will still be available at the old location (download.opensuse.org) until end of October 2022 . Make sure to change the URLs on your systems, so "apt upgrade" etc. still work as expected.
The reason for this change is, that we decided to self-host the openSUSE build service at https://obs.osmocom.org. See #5557 for details.
The Osmocom project has released new version 202206 of the CNI (Cellular Network Infrastructure) software, including OsmoTRX, OsmoBTS, OsmoPCU, OsmoBSC, OsmoMGW, OsmoMSC, OsmoHLR, OsmoSGSN, OsmoGGSN, OsmoSTP, OsmoSIPConnector, and others.
Those new tagged/released versions contain 7 months of work since the previous versions released during November 2021.
You can find pre-compiled binary packages of our latest release for a variety of Debian and Ubuntu GNU/Linux versions at Latest_Builds.
