OsmoCon2017 Programme

Below is a list of the individual talks/topics that we will cover as part of the schedule of OsmoCon2017.

Welcome / Introduction / Osmocom Project 101

This is a short introduction that will introduce you to the Osmocom project. It will give a short introduction to many of its member projects, as well as some background on the motivations and the people behind the project. Wile OsmoCon2017 covers only the cellular infrastructure projects (GSM/GRPS/EDGE/UMTS/HSPA), Osmocom in reality is much more than that.

Speaker: Harald Welte (Osmcoom Project Founder)

Running a basic circuit-switched Osmocom GSM network

This is an introductory talk running you through everything that's required to run a minimal small/private circuit-switched GSM network using the Osmocom stack and its various components. The focus will be very practical / hands-on. Target audience is to entrry-level users with limited experience in using OpenBSC & co. so far.

Speaker: Harald Welte

Configuring + running GPRS/EDGE data services with OsmoPCU, OsmoSGSN and OpenGGSN

Based on the previous talk about a circuit-switched GSM network, it will describe what is required to extend the network with GPRS and EDGE/EGRPS features. It will cover the required configuration changes as well as the related OsmoPCU, OsmoSGSN and OpenGGSN software.

Speaker: Daniel Willmann

Interfacing with VoIP using osmo-sip-connector

Having a private stand-alone GSM network is great, but most often people want to interface this network somehow to other networks, whether private or public. In the past, many people did so using lcr (Linux Call Router). LCR is a very powerful soft-PBX for Linux. However, in many cases a thin gateway to SIP is all that's required. So in order to reduce the complexity and to avoid having to understand and configure yet another program, osmo-sip-connector has been developed. This talk explains the MNCC interface of OsmoNITB and shows you how to add osmo-sip-connector to interface to external SIP PBXs or SIP providers using SIP trunking.

Speaker: Philipp Maier

Setting up a 3G network using osmo-iuh and a femto/small cell

GSM is a robust system with maximum interoperability and minimal spectrum requirements. However, the GPRS/EGPRS data speets are prohibitive for anything beyond very basic telematics usage these days. This talk will show you how to run a 3G network by using a femtocell and OsmoHNBGW in combination with your trusted Osmocom cellular core network components.

Speaker: Neels Hofmeyr

Using the Osmocom control interface

Everyone who has used Osmocom will have used its command line interface, the VTY. The VTY is a humand interface, designed for interaction of human system administrators with the system. However, there is also a much-underused CTRL (control) interface. It is a machine-parseable interface intended for interactions of external programs with the Osmocom software components.

Speaker: Max Suraev

Osmocom Roadmap

This talk will provide you with up-to-date information on current developments and the future of the Osmocom cellular infrastructure projects. A lot has been going on in the development community during 2016 and early 2017. The most fundamental changes in Osmocom are about to be merged to "master" and officially released: The split of the NITB (Network In the Box) into separate components. Stay tuned!

Speaker: Harald Welte

Reporting and investigating issues in Osmocom

No software is perfect, particularly not when it has to interoperate with mobile device from many different manufacturers, all of whom may have a slightly different interpretation of what the GSM specifications say. This talk will show you what you can do to investigate any issues you may encounter. It covers topics like the comprehensive Osmocom logging infrastructure, taking protocol traces of the various interfaces and GSMTAP. It also informs you how to report your findings to the development team in a way that provides them all they need for hopefully fixing the issue.

Speaker: Daniel Willmann

Osmocom Project Infrastructure (redmine, mailman, git, gerrit, jenkins, ...)

People with strong background in Free/Open Source Software projects are mostly familiar with various tools like redmine, mailman, git, gerrit, jenkins. However, if you're not from a development background, particularly not one from the FOSS world, they will be quite new to you. This talk is covering the various different tools the Osmocom projects use for communication, project management, revision control and continuous integration.

Speaker: Neels Hofmeyr

Fundamental GSM radio frequency planning

Operating a GSM network not only requires the hardware and software, but also requires some understanding of radio frequency propagation and radio frequency planning. Only with good planning, you will get the optimum network coverage and capacity. This talk cannot turn you into an expert in the field, but at least provides you with the fundamental concepts, such as path loss, link budget. It will also present some example calculations and tools (to be) released within Osmocom to help you with basic RF planning.

The talk also covers an introduction into the RF electronics after your BTS, i.e. coaxial cables, connectors, duplexers, filters, attenuators, terminators, antennas, etc.

Speaker: Harald Welte

Running a commercial cellular network with OsmoBTS/OsmoPCU/OsmoBSC & co

This talk will cover how On-Waves has been introducing Osmocom software into the operation of their commercial, roaming cellular
network. As an early adopter, On-Waves has around OpenBSC since 2010. Basically from day one, On-Waves has not been a passive consumer of
Osmocom software, but always been very active in their support of funding open source development in and around OpenBSC. Their
requirements are the reason many of the Osmocom programs (osmo-bsc, osmo-bsc_nat, osmo-gb_proxy, etc.) have been created, growing and
extending the family of Osmocom network elements. In this talk, we will learn what is possible in terms of production deployments, and
how a successful relationship between an "open source aware" operator and the community can look like.

Speaker: Roch-Alexandre Nominé, Founder and CTO of On-Waves ehf

Community Cellular Manager

CCM is a software management and deployment suite enabling the operation of small-scale cellular networks that can also be used with the OpenCellular platform we announced in June. It makes it possible for organizations with limited technical capacity to leverage OpenCellular or third-party radio access network (RAN) solutions to build small-scale cellular networks in their own communities. See for more information (and source code!).
