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. Regards

Hi all,
we need to wrap up the DGSM work and get it to a state that can be merged to
master.
There are still open issues that I am not sure how to solve, which I've
mentioned on some occasions, but it seems to not have been loud enough.
I would easily choose one way, but am not sure about others' opinions.
(1) One open point is the GSUP peer identification. I've added a comment
explaining it in https://gerrit.osmocom.org/c/osmo-hlr/+/16459/9
Me personally, I would strip down basically all of that complexity again and go
with the simplest solution, a nul terminated size limited char string for GSUP
peer id. The patch became what it is because vague requirements were thrown in
the mix and I tried to accomodate them, and now it ended up being a rather ugly
shim around a simple char string, really.
(2) Another open question is the freeing behavior in osmo_gsup_req (for proper
async handling of DGSM, and to ensure proper GSUP responses). I've added a
comment explaining that in https://gerrit.osmocom.org/c/osmo-hlr/+/16205/29
The gist for both issues is that I could write patches that would have a large
ripple effect throug many files and follow-up patches, but if we again disagree
on the outcome, the work would multiply.
So, DGSM works and is ready, except that we need to agree on what will be
accepted by review. I need opinions to be able to complete this (or possibly a
"go" to do whatever I think is right and merge that).
Thanks!

Hello:
I installed the osmo-NITB on ubuntu18.04, including
osmo-trx,osmo-bts,and openbsc.
I run these three applications in three terminals successively, it seems
ok, but the tx/rx leds on usrp-b210 hardware platform are not lighted,
and the print message in the osmo-trx terminal shows :
Thu Apr 30 15:28:28 2020 DTRXCTRL <0002> Transceiver.cpp:832
[tid=139871716352896][chan=0] command is 'POWEROFF'
Thu Apr 30 15:28:28 2020 DTRXCTRL <0002> Transceiver.cpp:977
[tid=139871716352896][chan=0] response is 'RSP POWEROFF 0'
I try to send some commands on another terminal which launch a telnet
session which connects to the osmo-bts control interface(port number is
4238) , but it not working.
what can i do next?
thanks a lot.
$ git clone git://git.osmocom.org/osmo-trx $ git branch * master $
./configure ... checking for LIBOSMOCORE... no configure: error: Package

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?

Andrew
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
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.

Hello Mr. Welte,
I am writing to ask you please, if it is possible to provide me with documents on the GSUP Client program. I have to implement my own application and send the required GSUP messages to the HLR to get subscriber data from hlr in Osmocom.
Many thanks for your considerations.

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!

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
Dear Developers,

#Run
./osmo-euse-demo
But i am now facing this error :
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
Can you please tell me what is the reasin behind this error !? And how can i solve it ?
Many thanks for your consideraion,

Hello all,
1) When an SMS is received from SMPP, the validity_minutes is not set (value 0).
The consequence is that email is deleted from database too early in case of failure.
In file: src/libmsc/smpp_openbsc.c function submit_to_sms translate convert from submit_sm_t to gsm_sms.
But some field of gsm_sms are not filled, in particularly validity_minutes.
I think that validity_minutes must be computed from submit_sm_t.schedule_delivery_time or submit_sm_t.validity_period.
Sorry I don’t know exactly content of these values.
2) In file src/libmsc/sms_queue.c function sub_ready_for_sm,
before sending SMS using the function gsm411_send_sms,
the SMS is not place in pending list. Like it is done in functions sms_submit_pending and sms_send_next.
The consequence is that when handset do a Location Updating Request,
only one SMS is send if they are many SMS for this subscribers.
Because in function sms_sms_cb call of
pending = sms_find_pending(network->sms_queue, sig_sms->sms->id);
will always return 0.
I try the following fix and was working
but I don’t know if it possible that an SMS was already in the list?
+ struct gsm_sms_queue *smsq = net->sms_queue;
+ struct gsm_sms_pending *pendingSms = sms_pending_from(smsq, sms);
+ if (!pendingSms) {
+ LOGP(DLSMS, LOGL_ERROR,
+ "Failed to create pending SMS entry.\n");
+ sms_free(sms);
+ return 0;
+ }
+ llist_add_tail(&pendingSms->entry, &smsq->pending_sms);
gsm411_send_sms(net, vsub, sms);
return 0;
}
Thanks you,
Denis
Dear Osmocom developpers,
I already installed osmocomnitb and now i am trying to Show the core Network vulnerablites in Wireshark.
In order to use existing Osmocom libraries for GSUP protocol processing and USSD coding / decoding, I have to use the file "osmo-hlr / src / osmo-euse-demo.c" in my osmocom directory, the " http: // git "contains. osmocom.org/osmo-hlr/tree/src/osmo-euse-demo.c "Pool. But i don’t find the following libarries to patch it.
#include <string.h>
#include <stdio.h>
#include <errno.h>
#include <signal.h>
#include <osmocom/core/msgb.h>
#include <osmocom/core/select.h>
#include <osmocom/core/application.h>
#include <osmocom/core/utils.h>
#include <osmocom/core/logging.h>
#include <osmocom/gsm/gsup.h>
#include <osmocom/gsm/gsm0480.h>
#include <osmocom/gsm/protocol/gsm_04_80.h>
#include <osmocom/gsupclient/gsup_client.h>
#include <osmocom/hlr/logging.h>
How can i have Access to the .exe (already maked) of this library.
Kind regads,
