version problem of libosmocore during installing osmoTRX
by cruise 30 Apr '20

30 Apr '20

$ git clone git：//git.osmocom.org/osmo-trx $ git branch * master $ ./configure ... checking for LIBOSMOCORE... no configure: error: Package requirements (libosmocore >= 1.3.0) were not met: No package 'libosmocore' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Then, check the information of libosmocore: $dpkg -l |grep libosmocore ii libosmocore:amd64 0.9.0-7 amd64 Open Source MObile COMmunications CORE library (metapackage) ii libosmocore6:amd64 0.9.0-7 amd64 Osmo Core library $ sudo apt-get install libosmocore ... libosmocore has already been the newest version (0.9.0-7)。 why???what can i do?

Docker containers.
by Andrew Back 25 Apr '20

25 Apr '20

Appreciate that the Osmocom Docker configurations exist principally for automated testing and here it may not make sense, but I wondered if builds are published to a registry? The Makefile in the make project located in the docker-playground repo sets docker.io as registry and has a target for docker push. Also see OBS Release.key files in project sub-directories, but couldn't find container builds being published anywhere. Was hoping I could just pull containers for the latest project versions, without cloning and building the containers in docker-playground. Also saw the comments from 2017 on Docker shortcomings and assuming SCTP works OK now in Docker networking? Regards, Andrew

GSUP client
by Reza Hosseini 24 Apr '20

24 Apr '20

Dear Mr. Welte, In order to be more familiar with the further development of the osmo-euse file, I need to know which libraries and which programming style I should use to be on the right track. Is it possible to provide me please the some lines of your code which is sending the USSD code via the GSUP client to hlr and called up data from OSMO-HLR? I need this for my master's thesis (Education Purpose), so I don't need a license for it. Many thanks for your consideration, Reza

Fwd: OSMOCOM TRX_BTS_BSC Connection Issue
by Aalto Koskinen 22 Apr '20

22 Apr '20

Hi, I looked at the forum for answers before posting, but I unfortunately couldn't get answers to what I was looking for. I looked into particular https://www.mail-archive.com/openbsc@lists.osmocom.org/msg09819.html for solving my issue. Setup: USRP B210 as radio head. NITB modules as components for 2G Network and BTS-TRX and TRX-UHD modules. Issue: - TRX-UHD and BTS-TRX fail. NITB Module works. Components of NITB network are able to connect to each other. - I have the RSP POWEROFF message originating in log from TRX-UHD module and the BTS module is shuttiing down. - BTS connects via OML but fails to connect RSL. - As per the previous email archive, I wanted to login to VTY and check the logs, but, it logs out as the BTS module shuts down (I cannot connect and see what's happening). I looked through the configuration files and seem correct to me. Any suggestions would be appreciated on solving the issue. I am trying to create a test 2G OSMOCOM network. Logs are written below and configuration as attachments.

Asterisk - Osmosom connection issue
by Laurent Kza 21 Apr '20

21 Apr '20

Hi all, I am new to the use of the Osmocom project, it is indeed a very nice job. I am currently trying to set up a configuration with a Asterisk PBX server and I have 2 questions: 1/ RTP configuration The SIP part (sip-connector vs Asterisk connection) works well so far, the communication starts but with no audio. I noticed that the RTP flux is sent to localhost instead of my server address (set as remote in sip-connector.cfg) and I was wondering if there is any possibility to send the RTP flow to an address which is not localhost ? sip local 0.0.0.0 5069 remote 127.0.0.1 5060 2/ codec issue In a configuration where all the Osmocom servers (MSC, MGW, BSC…) and Asterisk are on the same machine, it got a message from my asterisk server, saying that no codec can be found to start a communication. By default, the wiki/manuals states that gsm has to be used but perhaps I am missing something in the BSC configuration, especially in the codec choice. <--- SIP read from UDP:10.184.10.162:5069 ---> INVITE sip:899@127.0.0.1:5060 SIP/2.0 Via: SIP/2.0/UDP 10.184.10.162:5069;rport;branch=z9hG4bKpe1UXZU1amUja Max-Forwards: 70 From: <sip:422@0.0.0.0:5069>;tag=vyQKX32r72ZyQ To: <sip:899@127.0.0.1:5060> Call-ID: cd65c5a0-fdbf-1238-51a9-000c29cfd753 CSeq: 949096397 INVITE Contact: <sip:10.184.10.162:5069> User-Agent: sofia-sip/1.12.11devel Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE Supported: timer, 100rel Content-Type: application/sdp Content-Length: 133 v=0 o=Osmocom 0 0 IN IP4 127.0.0.1 s=GSM Call c=IN IP4 127.0.0.1 t=0 0 m=audio 4016 RTP/AVP 3 a=rtpmap:3 GSM/8000 a=sendrecv <-------------> --- (13 headers 8 lines) --- Sending to 10.184.10.162:5069 (no NAT) Sending to 10.184.10.162:5069 (no NAT) Using INVITE request as basis request - cd65c5a0-fdbf-1238-51a9-000c29cfd753 No matching peer for '422' from '10.184.10.162:5069' == Using SIP RTP CoS mark 5 Got SDP version 0 and unique parts [Osmocom 0 IN IP4 127.0.0.1] Found RTP audio format 3 Found audio description format GSM for ID 3 [2020-04-20 17:38:19] NOTICE[14918][C-00000015]: chan_sip.c:10957 process_sdp: No compatible codecs, not accepting this offer!

pysim contributions
by Sebastián Viviani 15 Apr '20

15 Apr '20

Hello, apologies for the generic question, but how can I contribute to the pysim project? I made a couple of fixes and added some stuff I needed for some tests, but looks like github rejects the pull requests, project is not listed in gerrit, there is no specific mail list, and the osmocom git repo rejects any push :-( Kind regards

Hi, we are looking for some help creating open source mobile communication infrastructure in the context of a search and rescue (SAR) mission at sea. We would like to use the osmocom stack as sensing and communication infrastructure at sea. How precise is the timing advance for localization? Neels mentioned that "modern" mobile stations equipped with a GPS receiver can report the location to the operator. Could you point me to the right standard? Is there any reliable and open source tooling to determine the direction of the signal with multiple receivers (e.g. SDRs) in close proximity? You can find out more about the project here: https://www.hs-augsburg.de/searchwing/ Sorry for the mostly German content. Thanks for your help! Best Regards Philipp Borgers

debug call failure on new nitb setup please?

Hi, I am setting up a nitb/nano3g right now and have the basics working with the nano3g talking to hnbgw and services running on my nitb box (rpi 3-something). I have two of the same phones: ZTE Obsidian with Android 5.1 which are able to connect to my network. When I try to call the other phone I don't get connected. It takes about 1 minute for the call to fail. Once the phone mentioned some problem with "access configuration for normal calls". Attached are my configs and logs from nano3g trace log and hnbgw journal during a failed call. Any help would be appreciated. I am sure I did something obviously wrong. I'll try and read the configs carefully to make sure that matches with what is up on the wiki. Thanks, Craig
