OsmoCon 2018

OsmoCon (Osmocom Conference) 2018 is the technical conference for Osmocom users, operators and developers!

We are happy to announce the date of OsmoCon 2018. It has been scheduled on October 18 + 19, 2018 and will happen in Berlin, Germany.

For the second time, the Osmocom Conference brings together users, operators and developers of the Osmocom Open Source cellular infrastructure projects, such as OsmoBTS, OsmoBSC, OsmoSGSN, OpenGGSN and others.

Join us for two days of presentations and discussions with the main developers behind Open Source Mobile Communications, as well as commercial and non-profit users of the Osmocom cellular infrastructure software.

You can find some initial information in our wiki at OsmoCon 2018, which will be updated as more information becomes available.

Call for Participation

We're also at the same time announcing the Call for Participation and call on everyone with experiences to share around the Osmocom member projects to submit talks, workshops, discussions or other proposals.

We are particularly looking for contributions about:

  • updates on features/functionality/status of individual Osmocom projects
  • success stories on how Osmocom projects are deployed in practice
  • migration from OsmoNITB to the post-NITB architecture
  • tutorials / workshops on how to setup / analyze Osmocom projects
  • statistics, reporting, operations aspects of Osmocom projects
  • third-party open source utilities to be used with Osmocom projects

Osmocom Conferences (OsmoDevCon + OsmoCon): OsmoDevCon introduces pretalx conference planning (1 comment)

Added by laforge 4 months ago

OsmoDevCon has successfully introduced the (obviously free/open source software) pretalx conference planning system for the schedule planning of the upcoming OsmoDevCon2018 conference.

All participants of OsmoDevCon submitting a talk have been receiving e-mails asking to confirm their respective talks/workshops using a confirmation link to the pretalx website.

We are planning to use pretalx for other upcoming events and would like to extend our thanks to the pretalx developers!

Cellular Network Infrastructure: Osmocom operates GSM/UMTS network at 34C3

Added by laforge 8 months ago

A team of Osmocom volunteers has continued the tradition of operating an experimental test network at the annual Chaos Communication Congress 34C3 held in Leipzig (Germany) from December 27 through December 30, 2017.

You can find some more information about this network at the GSM page in the 34C3 wiki and the report by tsaitgaist as part of the 34C3 infrastructure review (from minute 35 onwards of http://live.dus.c3voc.de/relive//34c3/8911/muxed.mp4)

Osmocom thanks
  • Deutsche Telekom for providing us with 3 ARFCN in the 1800 MHz band
  • Bundesnetzagentur for providing the experimental license for UMTS in the 850 MHz band
  • The team of volunteers working on the setup and operation of the network

Osmocom Conferences (OsmoDevCon + OsmoCon): OsmoDevCon 2018 Announced

Added by laforge 8 months ago

The 2018 incarnation of OsmoDevCon, the annual meeting for Osmocom developers has been scheduled for April 20-23, 2018 and will be held at the usual venue at IN-Berlin in Berlin, Germany.

For more information and Registration as well as submitting your talk proposals, see OsmoDevCon2018 and this mailing list thread

Contrary to OsmoDevCon, the date and venue for the user-oriented OsmoCon is still to be determined. It will be expanded from one to two days. Stay tuned for more news soon.

Cellular Network Infrastructure: Outreachy project selects Osmocom Debian Packaging

Added by laforge 9 months ago

The Outreachy project has selected work on Debian packaging for Osmocom for the Dec 2017 to Mar 2018 Outreachy Interns

You can read the related announcement at the outreachy announce mailing list

Kira "kobr" Obrezkova will be working on this, with Debian developer Thorsten Alteholz as mentor.

Congratulations, Kira! Thanks to Thorsten Alteholz for mentoring as well as to Outreachy and its sponsors!

In Osmocom, we have made tremendous progress during 2016 and 2017 in re-structuring our code base, with a proper 3GPP AoIP interface between BSC and MSC, the split-up of OsmoNITB, the externalization of the HLR and full 3G integration. This has had lots of fall-out in terms of packaging, and it's important to have the new post-NITB architecture packaged properly in upstream Debian.

Outreachy provides three-month internships for people from groups traditionally underrepresented in tech. Interns are paid a stipend of $5,500 and have a $500 travel stipend available to them. Interns work remotely with mentors from Free and Open Source Software (FOSS) communities on projects ranging from programming, user experience, documentation, illustration and graphical design, to data science.

OsmoBSC: OsmoBSC now *requires* an osmo-mgw to run alongside it

Added by neels 9 months ago

Heads up all OsmoBSC users: if you are deploying an osmo-bsc from osmo-bsc.git using the latest master branch (or nightly builds), you may notice voice streams not working anymore.

The reason is that OsmoBSC now supports intra-BSC handover (handover between separate BTS connected to the same BSC). To be able to redirect RTP streams between separate BTS, OsmoBSC now always requires an OsmoMGW instance to run alongside it.

Documentation on the Wiki and in the Manuals still needs to be updated, please bear with us until we get a chance to adjust those.

An OsmoMGW config example is

mgcp
 bind ip 127.0.0.1
 bind port 2427
 rtp net-range 4002 16000
 number endpoints 31
 rtp-accept-all 1

If OsmoMGW is running on the same machine as OsmoBSC with MGCP at 127.0.0.1, OsmoBSC needs no further configuration and will find the OsmoMGW by default at 127.0.0.1 port 2427. More detailed OsmoBSC side config can be issued like:

msc
 mgw remote-ip 127.0.0.1
 mgw remote-port 2427
 mgw endpoint-range 1 31

You can find OsmoMGW in the nightly (and "latest") builds as well as opkg feeds, it is installed by the osmo-mgw package and developed in the osmo-mgw.git repository.

The OsmoBSC change from which on we require an OsmoMGW is here

Previously, the higher level MGW would directly talk RTP to the BTS, which is now no longer the case. The BSC will always advertise its MGW's RTP ports towards the MSC. This means that the BTS can now be in a network segment that is not reachable by the MSC directly.

Cellular Network Infrastructure: Osmocom "latest" binary packages for Debian + Ubuntu

Added by laforge 10 months ago

Starting today, Osmocom offers an osmocom:latest package feed with Ubuntu + Debian packages of the latest tagged releases of all Osmocom cellular infrastructure software.

Since early 2016, Osmocom has already been offering Nightly_Builds of the master-of-the-day of each individual projects git repository to enable users to utilize Osmocom software without having to build from source. However, by their very nature, nightly builds are volatile as they track each indiviudal development step. This is interesting for users who are testing latest developments or who need to track fixes introduced only very recently.

The new Latest_Builds only change whenever a new release tag is set in the respective source code repository, i.e. every few weeks to months for a given project. While this is not a long-terms supported release, osmocom:latest is a much more suitable choice for deployments.
