Fabi: @ventskranz [FreiTalk N8] (chaotikum) Video 19.10.2018

Fabian Schwarze stellt sein Projekt @ventskranz im Rahmen des Freitalk N8 am 19. Oktober 2018 im Chaotikum vor. Vorweihnachtszeit 2017: Wie gestaltet man Weihnachten im einem Hackerspace? Die offensichtliche Antwort war: Bis auf die umherliegenden Süßigkeiten, den ein oder anderen Punsch oder auch den ein oder anderen Crepé ändert sich eigentlich nichts. Warum das nicht ändern: Ein Adventskranz so...

Inter-BSC hand-over in OsmoBSC (osmocon2018) Video 18.10.2018

How OsmBSC was extended to support inter-BSC hand-over next to the existing intra-BSC hand-over support. In 2018, OsmoBSC has undergone significant changes to allow inter-BSC (also called "external") hand-over on the A interface. The previous hand-over implementation only supported intra-BSC type hand-overs, where both the source and the target cell are served by the same BSC. In order to support...

Load-based hand-over in OsmoBSC (osmocon2018) Video 18.10.2018

In 2018, OsmoBSC has undergone significant changes to allow load-based hand-over between overlapping cells. This talk describes the implementation and its configuration/use. In 2018, OsmoBSC has undergone significant changes to allow load-based hand-over. The previous hand-over implementation only supported "link budget" type hand-overs, where a hand-over would be performed as a mobile station mov...

A Fault tolerant Core network - Distributed GSM (osmocon2018) Video 18.10.2018

How do you run a GSM network with unreliable backhaul, maintaining as many local services as possible available during periods of backhual outage? The traditional GSM core network is not suitable for backhaul on rural IP based internet type networks such as community mesh networks, local WISP providers, or satellite connections. We discuss some of the options for situation where intermittent backh...

External SMS Services using SMPP (osmocon2018) Video 18.10.2018

How to use the SMPP interface to implement external SMS services OsmoMSC has inherited the SMPP interface from OsmoNITB. It allows you to attach external programs that can receive and transmit SMS from/to your subscribers. The talk will explain the required SMPP configuration in OsmoMSC, as well as give some simple examples in C and Python on how to actually write such an external SMPP application...

External SS/USSD interface (osmocon2018) Video 18.10.2018

Introducing the GSUP based external USSD interface of the Osmocom Core Network stack In this talk Vadim will to share the state of external SS/USSD interface support in the Osmocom core-network stack. For many years there was the only one USSD-code (i.e. '*#100#'), that was used to get subscriber's extension. Recent developments in OsmoMSC and OsmoHLR have made it possible to connect an external U...

osmo-remsim: Remote SIM card Software (osmocon2018) Video 18.10.2018

A quick glance at what's happening on the R&D side with osmo-remsim. osmo-remsim is a set of programs that can be used to manage populations of SIM card emulators such as SIMtrace or sysmoQMOD and make them access remote sim cards inserted into card readers or SIM banks using network protocols. about this event: https://c3voc.de

Local Call, Local Switch: 3GPP LCLS in Osmocom (osmocon2018) Video 18.10.2018

This talk introduces 3GPP "Local Call, Local Switch" and covers the capabilities of the Osmocom implementation. Traditionally, in GSM the control plan and [voice] user plane share the same path. This means that the voice call user data between two subscribers within the same cell/area goes all the way into the core network (MSC) and from there all the way back to the same cell/area and the other s...

OsmoMGW, MGCP and how it is used (osmocon2018) Video 18.10.2018

This talk covers some MGCP background know-how, introduces OsmoMGW and explains how OsmoMGW is used by OsmoMSC and OsmoBSC to control the RTP user plane of voice calls. This talk covers some MGCP background know-how, introduces OsmoMGW and explains how OsmoMGW is used by OsmoMSC and OsmoBSC to control the RTP user plane of voice calls. about this event: https://c3voc.de

SIMtrace2 - an incremental update to SIMtrace (osmocon2018) Video 18.10.2018

In 2018, after 6+ years of SIMtrace, we finally released SIMtrace2. This talk introduces the what, how and why. SIMtrace2 is an incremental step to SIMtrace. On the outset, it looks like a minimal change: Simply replace the SAM7S with a SAM3S microcontroller. However, due to the completely different CPU core architecture, the firmware was re-written from scratch. SAM3S supports more USB endpoints,...
