New Osmocom Cellular software versions released!

Added by laforge 29 days 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.

Noteworthy Changes

Misc

  • the asciidoc source of the user manuals + VTY reference manuals is now always kept inside the respective repository: osmo-bts.git contains the osmo-bts manual. Before this, we used to have all manuals in osmo-gsm-manuals.git.
  • logging vty: deprecate the 'everything' keyword
  • various logging related improvements
  • various improvements of osmo_fsm
  • new osmo-config-merge utility

  • introduce osmo_timerfd support as part of libosmocore (recurring timers)

OsmoTRX

  • Introduce OsmoTRX user manual
  • Direct support of LimeSuite as osmo-trx-lms without the detour of uhd+soapy-uhd+soapysdr

  • optional forward of SMS via GSUP to/from HLR rather than using internal SMSC
