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:

Sorry for the mostly German content.
Thanks for your help!
Best Regards

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,
I am trying to build the osmo-euse-demo on the Osmocom VM, executing the following commands:
#Install required development libraries:
sudo apt-get install libosmo-gsup-client-dev
#Get the source code and a missing header file
wget https://raw.githubusercontent.com/osmocom/osmo-hlr/master/src/osmo-euse-dem…
wget https://raw.githubusercontent.com/osmocom/osmo-hlr/master/include/osmocom/h…
mkdir -p osmocom/hlr/
mv logging.h osmocom/hlr/
#Compile source
gcc -I. -o osmo-euse-demo osmo-euse-demo.c -losmocore -losmo-gsup-client -losmogsm -ltalloc
#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 ?

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,
Reza
