Re: Help with sccp library

I means: is the interaction with mtp3 layer implemented (is sending sccp data by mtp3 implemented by the library?)? Also, what about the reception of data from mtp3 layer. is that implemented in the sccp lib. I am asking these questions because I see the code of mtp3 in the lib but no significant call is present in the sccp part of the lib. Thank you for your help.

SimpleHLR: A web interface for OpenBSC
by Peter Caprioli 03 Jun '13

03 Jun '13

Hello everyone, I've just finnished writing together a small web interface for the OpenBSC HLR. It allows you to modify various parameters in the database and also provides a set of functions to modify the HLR or sending SMSes in your own scripts. The project is still very alpha but it seems to work reasonably good. Feel free to give any feedback! Screenshots and source code is available on my website: https://stormhub.org/simplehlr/ -- *Best regards, Peter Caprioli*

Several questions
by jason mercury 06 Dec '12

06 Dec '12

I have some questions: 1) When I start bsc_hack bsc_init.c first establishes OML link and initializes the bts then it establishes RSL link and bts starts broadcasting. However, it takes so much time to start the bts. Instead of this I want to do the following: it establishes OML link at the beginning and only once, then when i want to start broadcasting it establishes just the RSL link and bts will start faster since i don't have to wait for OML link. What should be done for this? 2) If i send one or two word messages from telnet interface it is okay. But if i send a longer message the phone could't receive the end of the message correctly(last words may be incomplete). Did any one encounter with this problem? What is wrong with me? 3) Could I send SMS in which extension of the sender is text not integer. For example, i want to send an information SMS that this is a test network. For this purpose i want to send an SMS from 'OpenBSC'. I set the extension of the first subscriber in database as text and tried to send the SMS but SMS wasn't delivered. What should i do? 4) Can i add SMS externally to SMS table of database? Thanks. Jason

OpenBSC with Dahdi+Asterisk and several BTS
by Ellen Apolinar 18 Jun '12

18 Jun '12

Hey folks, I am new with OpenBSC and want to build OpenBSC with several BTS from different types. At first what I need: I want to test OpenBSC without a BTS just to see if the installation worked successfully. Also I need to know what I have to do if I want to use a BTS which isn't configured yet. What we want to do in the end is to test the BTS with a selfmade programm. For this we need an interface between the hardware BTS and the pc. What I have: Ubuntu 11.10 Kernel 3.0.22 several BTS (Siemens BS60/BS240, Nokia Citytalk, Alcatel G9100 etc...) HFC-E1 card from Cologne Chip OpenBSC Asterisk 1.8.4.4 + Web-GUI (Asterisk NOW 2.0) Dahdi 2.4.1 Libpri 1.4 mISDN v2.x mISDNuser 2.0.11 LCR 1.7 Twinkle, Wireshark etc. Why mISDN + Dahdi: First I tried to use mISDn + mISDNuser + LCR for a connection between OpenBSC and Asterisk. mISDN was integrated in the Kernel so I thought it's the best idea to use it. I installed mISDNuser and LCR but there are several problems. For further informations you can have a look here: http://www.ip-phone-forum.de/showthread.php?t=247932 Because of the problems mit LCR/chan_LCR and Asterisk I decided to use Dahdi because it's also installed since I installed Asterisk. Asterisks works fine with the softphones which I created with Twinkle and also the Asterisk GUI works without problems. To use Dahdi: modprobe -r hfcmulti modprobe -r mISDN_core /etc/init.d/dahdi restart /etc/dahdi/system.conf: dchan=1 bchan=2-30 openbsc.cfg: e1_input e1_line 0 driver dahdi To start OpenBSC: cd /etc/openbsc/src/osmo-nitb ./osmo-nitb Error: <0005> bsc_init.c:493 Failed to parse the config file: 'openbsc.cfg' So now I'm not sure what to do because I'm not sure what exactly is wrong and if it could work without a BTS. There are enough informations if I want to test a BS11 or a nanoBTS but I'm a little bit lost how to work with another BTS. In the next day I will get the traces from the several BTS to build an interface between BTS and OpenBSC so I can build the openbsc.cfg-file. But it would be great if it is possible to test OpenBSC before I get the traces. To get a connection between OpenBSC and Astrisk with Dahdi is a problem which I should solve by myself. There should be enough information in the internet. if you have questions or need more informations just write an e-mail. Best regards and thanks in advance. It would be great if someone could help me or give me some advice what I could do. Ellen

LCR compilation problem
by Arturo Rivas 08 Jun '12

08 Jun '12

Hi! I'm trying to install OpenBSC+LCR. I'm following the next tutorial: http://openbsc.osmocom.org/trac/wiki/OpenBSC_LCR I have installed libosmocore and openbsc but I can't install lcr. I tried to apply patch from tutorial but it doesn't works, maybe version is so old because gsm_bs.cpp is not the same. When run configure terminal shows: configure: error: in '/home/rivas/OpenBSC/lcr' configure: error: --with-asterisk was given, but test for header-file asterisk/compiler.h failed I have new Ubuntu 12.04 and I have install asterisk from apt-get repository. Someone can help me? Also I need to know if there is a tutorial recently actualized. Best regards, Arturo Rivas.

First version of Erlang based telnet server
by M. Josenhans 29 May '12

29 May '12

Hello, while there there is a comandline interface for openbsc to configure the BSC software, until now there has been nothing comparable as user interface for the osmocom/Erlang code. This has changed. Here is a first version of an Erlang written command-line interface: https://github.com/josemic/Erlang-command-line-interface Be aware that there is currently only dummy data presented. It has not yet been integrated with the osmocom/Erlang code. Please test and provide feedback. For installation instructions please see github wiki pages. Br, Michael

sim
by Hans Witvliet 24 May '12

24 May '12

Hi all, Perhaps i am completely mistaken.. If so, please make it a "learning-moment" for me ;-) Is it possible to crate your own SIM's ? As far as i can see, these are just small smartcards. And as such, thse can be filled with the tools that come along with OpenSC. I presume the SIM's contain a number of EF's and DF's One set that thighs a SIM to a specific operator (making it possible to SIM-lock a handy) And another set of EF's that identifies a specific user. Within the DB of the operator, the relation between the SIM-identifier and the specific user (with his 06-number and other info) is made. (I know that the sim itself is not unique, because a college had a malfuntioning SIM, and it was replaced by another one, with the same content) Reason why i want to fill my own sims is this; For one of our projects we are using certificates on a smartcard. Currently full-sized, but we think of putting it on a sim-sized card. And use it in a dongle along with 2Gb (bootable) flash storage. So my questions are: 1) can you burn your own sim's 2) would there be any objections to have, beside de GSM-info, also a certificate 3) could you "clone" an existing SIM? With regard to the last one: If i buy a couple of prepaid-sims from a operator, would it be possible to extract that info, and put it along with my own certificates on a sim of my own? Obviously, it is no use to contact the help desks of kpn, tele2, or vodafone at this moment. But _if_ their are no technical limitations i could do a test with some of our own BTS'es. And if that pilot works, we have a business case for any interested operator. Hans
