== 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 http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2018 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.

Osmo-bts "shutdown timer expired"
by Георгий Прайзендорф 15 Jun '18

15 Jun '18

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 01 Jun '18

01 Jun '18

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: 　 .

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 30 May '18

30 May '18

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 29 May '18

29 May '18

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 28 May '18

28 May '18

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.)

by Sandi Suhendro 25 May '18

25 May '18

Dear list, I have question about osmo-trx config with osmo-bts-trx. if in osmo-bts-trx osmotrx ip local 192.168.100.73 osmotrx ip remote 192.168.100.100 then what ip address fill on osmo-trx for limesdr.cfg? bind-ip 192.168.100.73 remote-ip 192.168.100.100 Please correct me, cause I confuse osmo-trx won't running if not using same ip as 127.0.0.1 well, Does 127.0.0.1 is fine for only sms/call network in new split? please advise. Thanks. -- Best Regards, DUO

OsmoCon 2018 CfP / submit your topic[s] *now* !
by Harald Welte 25 May '18

25 May '18

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.
