libosmocore/BSC/MSC: MO voice calls rejected from Siemens S11E (patch included)
by Lennart Müller 31 Jan '24

31 Jan '24

Hi, I had a problem placing MO GSM calls from a Siemens S11E: The calls were dropped immediately; Osmo-MSC reports "Cannot compose Channel Type from bearer capabilities" After investigating the SETUP request from the S11E, the phone does not use octet 3a (no extension bit set in IE 3). Wireshark decodes the radio channel requirement as "Full rate support only MS/fullrate speech version 1 supported", so I added a condition to the gsm48_ie.c function of libosmocore to include at least GSM FR in the list of available speech_ver in case octet 3 has no extension. Attached to this message are the Abis-IP PCAP traces of MO calls, and the patch for gsm48_ie.c. Regards, Lennart

Problem while running NIB on Open Cellular Base sation
by Brackley Casinga 31 Jan '24

31 Jan '24

Hi, My name is Brackley Cassinga Form DRC, we run a community network called pamoja net where we offer gsm services using osmocom open source software and OC Base station. Recently I have tried to install another base station as the same installed but I could not find any resource guiding through all the steps to take to run NIB on a base station. I'm currently running Ubuntu and I will appreciate if you could guide me on the installation of BSC,hlr,MSC , in order to run a basic gsm network. Thank you.

Helping an Australian set up his own personal GSM/2G cell
by Mychaela Falconia 28 Jan '24

28 Jan '24

Hello Osmocom community, I have a contact in Australia who reached out to me with a desire to set up his own personal GSM/2G network. Australia is a nasty anti- retrotechnology country, even worse than USA, where all official 2G networks were shut down back in 2018. As most of you know, I run my own pirate-radio GSM cell in USA, and I tried reaching out to other Vintage Mobile Phone communities, promoting the idea that people can run their own networks using Osmocom CNI plus suitable hw plus my ThemWi add-ons for outside PSTN interconnection, and offering to teach others how to copy what I am doing. When I made the latter offer to the community, I was expecting people from other parts of USA - but right now the only person with an active interest is in Australia. I am currently teaching my Australian contact the "pure physics" aspects of running your own GSM network: what frequencies are usable for GSM, dB and dBm units of measurements, how to use a handheld spectrum analyzer etc. These are all "physics" topics that are independent of where one happens to be geopolitically. But there is another key aspect which I feel he needs to know, but which I won't be able to teach him: country-specific spectrum-political aspects. I know the spectrum-political landscape in USA: how FCC has divvied up PCS1900 and GSM850 bands (or B2 & B5 in modern parlance) between carriers, which spots in these bands are completely unused and thus reasonably safe to squat in, and how one can exploit the overlap between EGSM900 DL and USA ISM band to run a BTS with low probability of getting into trouble. But I have absolutely no such knowledge for any other country in the world, let alone one as remote and foreign to me as Australia. Is there anyone in this community who is based in Australia and knows this topic? I would greatly appreciate any advice from an AU-knowing person that I could pass to my GSM-enthusiast contact: out of the 4 frequency bands that are in-principle suitable for GSM, which is the safest one to squat in for a pirate operator, and which ARFCN range(s)? Obviously I will teach my contact that he needs to pick a spot where the spectrum analyzer shows nothing but noise floor, but just because a spot "looks blank" on an SA doesn't mean that the spot is safe to squat on, without knowing anything at all about the country's spectrum-political landscape... TIA, Mychaela

TCP port numbers for vty/ctrl/etc of 3rd-party programs
by Mychaela Falconia 03 Jan '24

03 Jan '24

Hello Osmocom community, I have a question about TCP port number assignment for programs using libosmovty. Every Osmo-official server program gets official port number assignments listed in the wiki, in PDF manuals etc - so far, so good. But what about non-Osmo-official 3rd-party programs that wish to use common Osmocom libraries, including the vty facility? Suppose that an operator of an Osmocom-based cellular network needs to develop some additional programs to satisfy some operational need, and some of these additional programs are long-lived server processes for which an Osmocom-style vty interface would be very useful. But implementing such a telnet vty i/f requires a TCP port number... Has anyone thought about designating an official range of TCP port numbers which would be recommended for vty/ctrl/etc ports of processes that use Osmocom libraries and extend Osmocom CNI in various ways, but aren't official Osmocom projects? M~

OsmoDevCon 2024 planning
by Harald Welte 26 Dec '23

26 Dec '23

Hi all! [cross-post to make sure everyone knows about it, please follow-up-to the osmodevcon(a)lists.osmocom.org mailing list for further discussion] As I mentioned several times at different occasions, I really think we should put together a OsmoDevCon again. In case you don't know what that is, please see https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon We should have restarted already in 2023, but I really was too busy and it was a somewhat difficult year for me at times, sorry. Date ---- In terms of timing, I am thinking about "after April but before the main summer holiday season (June-August)". That leaves May. Given that May has the whitsunday weekend as well as GPN (Gulaschprogrammiernacht, a CCC event that will likely conflict of interest with some people interested at attending OsmoDevCon), I'm currently considering the following candidate dates: * May 3 to 6 * May 24 to 27 This is as usual a friday-to-monday timeframe, allowing people who don't work professionally on osmocom to attend just the two weekendd days, while others can attend the full 4 days. Venue ----- In terms of venue, I'm hoping we can move to a slightly different arrangement where the whole group stays together for the whole duration of the event - as opposed to everyone staying at different hotels and having to commute from hotel to venue and back every day. So something like a hotel with a sufficiently large meeting room, hotels and catering all day. And all of that ideally at a nice venue with some kind of park / outdoor area, not downtown at the city center. Yes, that will obviously come at a higher price tag than we're used to - but I'm confident we can get that covered between sponsors and sysmocom. Do you guys think this is a good idea? Or would you prefer the traditional ad-hoc approach at IN-Berlin?
