rtl-sdr: Weekly windows binary packages for rtl-sdr and osmo-fl2k

Added by laforge about 1 month ago

While Osmocom in general is a very much Linux-centric development community, we are now finally publishing automatic weekly Windows binary builds for the most widely used Osmocom SDR related projects: rtl-sdr and osmo-fl2k.

You can find the binaries at The actual builds are done by roox who is building them using MinGW on OBS, see

The status of the osmocom binary publish job, executed once per week from now on, can be found at https://jenkins.osmocom.org/jenkins/view/All%20no%20Gerrit/job/Osmocom-OBS_MinGW_weekly_publish/

OsmoMSC: Handover support merged to OsmoMSC master

Added by neels about 2 months ago

We are happy to announce that OsmoMSC handover support for 2G has been merged to the master branch yesterday.
See this talk: https://media.ccc.de/v/osmodevcon2019-103-inter-msc-handover-how-it-works-and-how-we-implement-it
and sensational images of the new code launched to the OsmoMSC master orbit: http://people.osmocom.org/neels/oeZeich5/msc_launch.jpg ;)

OsmoMSC master can now do both inter-BSC as well as inter-MSC handover for 2G (GERAN).
Until now, only OsmoBSC supported handover, i.e. an ongoing phone call moving to another cell within the same BSC.
OsmoBSC since not so long ago can also handover to another BSC, but you needed a third-party MSC for this.

Now, you can use our stock OsmoMSC for inter-BSC handover. Notably OsmoBSC has also received crucial fixes for handover on AoIP.
We also support inter-MSC handover now, i.e. you can handover a 2G call to another OsmoMSC.
To handover to/from a third-party MSC, a separate GSUP-to-MAP compatibility layer will have to be added.

A rather large refactoring effort was necessary to allow handling more than one RAN connection per subscriber.
Though handover to/from 3G is not yet supported, the new code base is a necessary preparation for adding that.
It is not yet clear when or by whom handover on 3G might be taken on, so join us if you are interested.

OsmoMSC v1.4.0 was released to mark a stable version before the new changes.
After due testing by the extended Osmocom community, we will (likely soon) tag a new "latest" release.
Until then, handover support is available in the nightly images and when built from current master.

Cellular Network Infrastructure: Binary packages for Raspbian 9

Added by laforge 5 months ago

Thanks to the great support of the OpenSuSE Build Service, Osmocom is now offering binary package feeds for the popular Raspbian distribution, Version 9.

As a result, running Osmocom CNI (Cellular Network Infrastructure) on Raspbery Pi embedded computers is easier than ever: Just add the Latest_Builds
or Nightly_Builds feed to /etc/apt/sources.list[.d] and run your Osmocom based 2G and/or 3G cellular network.

Cellular Network Infrastructure: New Osmocom Cellular software versions released!

Added by laforge 5 months ago

The Osmocom project has released new version of the CNI (Cellular Network Infrastructure) software, including OsmoTRX, OsmoBTS, OsmoBSC, OsmoMGW, OsmoMSC, OsmoHLR, OsmoSGSN, OsmoGGSN.

Those new tagged/released versions contain half a year of work since the previous versions released during summer 2018. The primary focus was on bug-fixing and stabilization as well as some major new features, such as inter-BSC-handover support in osmo-bsc.

You can find pre-compiled binary packages of our latest release for a variety of Debian and Ubuntu GNU/Linux versions at Latest_Builds.
