Osmo-bts "shutdown timer expired"

by Георгий Прайзендорф

Hi, sorry for my English. I installed osmocombb on Kali rolling. When i'm trying to start my own bts, it works for 4 seconds, then i can see message "Shutdown timer expired". Bellow you can see my config files. 1 screenshot - 2 trx firmware on motorola c115. 2 screenshot, left - follow the commercial BTS timer, right - starting MSC, SMS, HLR. 3 screenshot - starting osmo-bts. 4 screen - my problem. I can connect with telnet to BSC and BTS, but BTS - only for this 4 seconds, when it's up. I didn't replaced filters on motorola, is it my problem? Or i just need to install smth more? Also, if i write to the wrong mail list, tell me please where should i write with my problem?

nanoBTS constantly restarting

by Michael Spahn

Hello all, I have recently tried migrating an OsmoNITB setup to the new standard using mostly this guide right here: https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_I… <https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_I…> However, while my nanoBTS works perfectly fine in the old setup, it just doesn not work at all in the new one. When I start osmo-bsc the LED on the BTS starts flashing green after a few seconds and then stops flashing and just stays green all the time, which is the expected behaviour. Unfortunately though, after another couple of seconds, the LED starts flashing green again and then turns red. This is what the log shows: BTS 0: Failure Event Report: Type=processing failure, Severity=critical failure, Probable cause=Manufacturer specific values: Fatal software error, Additional Text=l2_bch.c:1154 **** ** l2_bch.c#1154:BCHbcchSItypeValid( prim_p->infoType ) ** IPA_SW_FATAL_ERROR ** In task "TRX Proc:L2_BCH" @ (1063). **** 　 . BTS 0: Failure Event Report: Type=processing failure, Severity=critical failure, Probable cause=Manufacturer specific values: Fatal software error, Additional Text=TRX Proc:L2_BCH:l2_bch.c#1154 (1063). BTS 0: Failure Event Report: Type=processing failure, Severity=warning level failure, Probable cause=Manufacturer specific values: Software warning, Additional Text=31385:WARN:OAM_RES:trx_fatal_error_log.c#255:TRX has logged the error: 　 .

BTS 0: Failure Event Report: Type=processing failure, Severity=warning level failure, Probable cause=Manufacturer specific values: Software warning, Additional Text=31385:WARN:OAM_RES:trx_fatal_error_log.c#260:BCHbcchSItypeValid( prim_p->infoType ) 　 20180328072641280 DLINP <0013> input/ipaccess.c:247 Sign link vanished, dead socket 20180328072641281 DLINP <0013> input/ipaccess.c:71 Forcing socket shutdown with no signal link set 20180328072641282 DCTRL <000e> osmo_bsc_ctrl.c:160 No more BTS connected, sending TRAP. 　 Now I'm not claiming that my config is already 100% correct but I feel like this isn't a configuration issue. I'm using the most recent nightly builds of the entire osmocom library. Does anyone know what could be at fault here? Kind regards, Michael Spahn

React to IMSI Attach but not PERIODIC

by Keith Whyte

Hi All, I have a use case where I'd like to react to MS connecting to the network, that is on initial IMSI ATTACH. We already have the SMPP alert notification mechanism which can be used, but unfortunately in SMPP the ms_availability_status only has 3 posible values in the spec: 0: Available 1: Denied 2: Unavailable. So currently if I react to status 0, this would also happen on periodic LURs I could keep state separately but that sounds prone to errors. The external process reacting to the alert notification could try somehow to get the previous status from HLR or database, but that sounds like a race condition. One possibility might be to extend this with a further custom value 3: Available (Initial Attach) or some such? Any thoughts?

UICC with ISIM application

by Tomcsányi, Domonkos

Hello All, Sorry if this is an off-topic question, but I was wondering: does anyone know of any carrier that actually uses a UICC ('SIM card') with the ISIM application installed? So far all cards I saw have only USIM, maybe CSIM on them. I'd like to extend Benoit's card library with ISIM support, but there is no way to test my code right now, so I'm thinking about buying maybe a card. Thanks. Domi

Writing FPLMS to SIM

by Keith Whyte

Hi all Somebody mentioned recently (at osmodevcon was it?) about writing to the FPLMNS list to avoid service loss due to LUR reject cause 11 (I think?) I notice we don't seem to have this an a option in pySim-prog.py, so I am wondering what tool was used? Thanks! (I noted the commented FIXME section for HPLMN in pySim.read.py and from there was able to modify read address and read and decipher the FPLMN list, although i did not get a nice readable output format yet.)

OsmoCon 2018 CfP / submit your topic[s] *now* !

by Harald Welte

Dear Osmocom community, one of the main difficulty with OsmoCon 2017 last year was that nobody submitted talks / discussions within the deadline, early enough to allow for proper planning. This lead to the situation where the sysmocom team had to come up with a schedule/agenda on their own. Later on *much after the CfP deadline*, people then squeezed in talks, making the overall schedule too full. It is up to you to avoid this situation again in 2018 by submitting your talk *RIGHT NOW*. We will be very strict regarding late submissions. So if you would like to shape the Agenda of OsmoCon 2018, this is your chance. Please use it. We will have to create a schedule soon, as [almost] nobody will register to a conference unless the schedule is known. If there's not sufficient contribution in terms of CfP response from the wider community, don't complain later that 90% of the talks are from sysmocom team members and only about the Cellular Network Infrastructure topics. You have been warned. Please make your CfP submission in time at https://pretalx.sysmocom.de/osmocon2018/cfp before the CfP deadline on *2018-05-30 23:59 (Europe/Berlin)* Thanks for your kind attention. Looking forward to meet with the community at OsmoCon 2018 in October.

The reason why you see paging by IMSI in real-world GSM networks

by loay abdelrazek

Hello All I wanted to ask your about something regarding user privacy leakage in the broadcast channels. As i have been sniffing and testing myself and i found that on the paging requests type 1 IMSI along with TMSI is sent. I have came to understand that first sending two identifications is the norm, but what i dont understand the high rate of sending IMSI as mobile identification, and as per specification its noted that either TMSI OR IMSI are sent, so does that by any mean could be a configuration issues from the MSC/VLR side that should be changed, is this the norm? if its the norm, then why using TMSI. >From your experience what are the countermeasures you think that should be taken from the operator side to protect against such information leaks, or there is nothing that an operator can do much for this ?What could be the different cases where the IMSI could be sent ? Thanks

requesting working demo config files for 2g setup osmomsc, osmobsc, osmostp,osmohlr, osmomgw

by toby

Dear All, I was wondering whether anyone could please provide me a set of fully working configuration files for a network-in-the-box setup with msc, bsc, stp, hlr, mgw parts (not osmo-nitb). I have successfully compiled all the required software from source, however, the migration guide is incomplete and I cannot seem to find a simple tutorial for building an osmo network from scratch using all the new components. I want to set up a 2g network for calls/sms, i don't need gprs though. Thanks! Sincerely, Toby M.

libsmpp34 C code sample to receive SMS

by Rafael Diniz

Hi all, In libsmpp34 git there are examples on how to send an SMS (esme in test_app directory, for example), but none to receive on SMS (from osmo-nitb / osmo-msc tcp smpp port). In case anyone has some sample C code to receive SMS using libsmpp34... it will help me. ; ) Thanks, Rafael Diniz

LIBVERSION of libsmpp34

by Thorsten Alteholz

Hi, I stumbled upon LIBVERSION in src/Makefile.am of libsmpp34. Is there a reason why it changed from 0:1:0 to 1:0:0? At least the names of all exported symbols did not change!? Thorsten

OsmoHLR understanding/documentation/testing

by Mykola Shchetinin

Good day, ladies and gentlemen that's a great community you have. Mobile communications programming is a demanding field requiring best developers. I would be extremely grateful if you find time to answer a couple of my simple questions. I found myself reading the code of OsmoHLR project in order to understand how it works and how the GSUP protocol works (it seems that the only example of the GSUP-server is OsmoHLR). How do you understand the code when you need to modify it or accomplish other things that programmers usually do? It seems to not be documented much. Though I feel fluent in C, I find it hard to understand what is going on there. I've come up with an idea of running the OsmoHLR with a debugger. But in order to see what actually happens in the code when the location update is being performed (for example) I need to have the real phone and the real BTS, don't I? How do you check that the code is working as intended? Thank you very much! Kind regards, Mykola Shchetinin

I would expect your university has some BSC/network simulator or a core network+BSC to get those BTSs up and running? How were they used so far? If you have some kind of environment where the BTSs can be brought up, and you have some additional E1 interface cards so you can trace the interface between BSC and BTS, a significant step forward is made. However, if you don't have protocol-level documentation from Huawei or ZTE, and you cannot get any Abis protocol traces of BTS bring-up, it is almost impossible to get them ever supported from Osmocom, sorry. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

expected osmocom.org downtime on Sunday, 2018-05-13

by Harald Welte

Dear Osmocom community, this sunday (May 13), I'm planning to do some of the pending migration of osmocom.org services from our old server to a new machine. This will cause some downtime. Hopefully it will be minimal, but I'm sure there will be unexpected events that will mean some of the osmocom.org services will be unavailable at some point during Sunday. In terms of priorities, gerrit is high up on the list, so this will be my primary focus. If that goes well, redmine is the next on the list. In case you're interested in the gory details, https://osmocom.org/issues/3076 is the overview ticket. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

osmocom-bb installation problems

by Nikos Balkanas

Hi, I am new to this list. I use ubuntu 14.04.02. I am trying to configure/compile osmocom-bb. I have a few questions and problems: According to the src/README.building file, I should get the arm toolchain from gnuarm.com This should be updated, gnuarm.com doesn't have any downloads any more. Instead I installed gcc-arm-linux-gnueabi from ubuntu reps 1) normal gcc seems to support x-compiling for arm CPUs. Why not use that? 2) Your stock Makefile tests for CROSS_HOST against arm-elf-gcc. This should be updated to test also against arm-linux-gnueabi-gcc from gcc-arm-linux-gnueabi package 3) configure warnings: configure: WARNING: unrecognized options: --disable-tests, --disable-tests. Should be disabled if not supported any more checking for arm-linux-gnueabi-mt... no checking for mt... mt configure: WARNING: using cross tools not prefixed with host triplet Is this a problem? 4) configure asks for libosmovty. Despite listed, couldn't find it under osmocom libraries any more:( Where can i download it from? TIA, Nikos
