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.

Hi all!
For some time, Ivan of Fairwaves has been working on PCU code for
OpenBTS. In order to not have to re-implement NS/BSSGP, he used the
openbsc/src/libgb/* code that we already had as part of openbsc.git
I've now finally found some time and completely separated this code from
all the dependencies to openbsc stuff and migrated it as new "libosmogb"
into the libosmocore.git repository. This has been done with git
filter-branch, and thus the history has been preserved during the
migration. All Gb code has now been removed from openbsc.git.
This separation has been much more painful than anticipated (especially
on the BSSGP side), and the result is not very clean either. I hope to
get back and clean this up further at some point, providing a better
interface between applications and the library.
Ivan's PCU code is now in osmo-pcu.git on git.osmocom.org, and I've also
already ported it over to use the shared libosmogb. The latter is not
yet pushed, but I'll do that soon. I've also removed any other direct
include and/or linking against openbsc/osmo-sgsn/openggsn, so the PCU
can now build fully autonomously, just linking against the shared
libosmo{core,gsm,vty,gb}.
Next upcomig will be the support of osmo-bts (sysmoBTS hardware) from
osmo-pcu. Andreas Eversberg has been contracted by sysmocom to spend
some time on this.
There is also a new osmocom-pcu(a)lists.osmocom.org mailing list for those
interested specificall in GPRS PCU issues. We thought it is best to
keep it separate, as it will be of interest to people from the OpenBSC
as well as the OpenBTS communities, and list-crossposting might not be
the best thing to do.
Regards,
Harald

Hi all,
I am currently trying to implement GSM Test-bed.
I am having gnuradio 3.3.0 openBTS-UHD 2.8. Both are installed successfully.
I have USRP1 with one daughter board RFX900 and antenna is connected to
TX/RX.
I have given --wuth-usrp1 and --with-singledb as argument to ./configure of
OpenBTS. I have configured Tranceiver52M also.
When i probe the usrp it is giving me frequency as 64MHz.
My problem is when i run OpenBTS ,it is giving error like

Hi list!
I have a installation problem with OpenBSC+LCR. I tried to install it following tutorial in the wiki and not working. I have some problem and I probe to install in various unix version Ubuntu based but I can't.
I believe that codes are changing and tutorial doesn't work. Someone have installed OpenBSC+LCR recently? Pleased tell me how!
In addiction, I need to know if there are documentation about the codes to complain how it work to study the program and understand it. Are there documentation available?
Thank you!
Hello list!!!
I'm trying to register subscribers but I can't. In terminal I write:
'subscriber imsi <imsi> authorized 1' but say that doesn't found this
subscriber... I tried with the SIM attached in network but doesn't work.
BS,
Arturo Rivas.
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.
Hi,
I'm presently attemping to work with the code here:
<http://cgit.osmocom.org/cgit/erlang>. I've followed the instructions
in <http://cgit.osmocom.org/cgit/erlang/mgw_nat/tree/INSTALL>, the
section titled "Installation procedure (manual)".
So far, I've gotten osmo_ss7 to build, and I'm figuring out how to use
it. However, osmo_map depends on signerl, and I can't for the life of
me figure out how to build signerl properly.
Is there something I'm missing? (I just started working with Erlang
this week, so I may be missing something completely obvious.) I think
the main issue is the makefiles aren't putting generated asn.1 code in
places that Erlang expects to see headers and code, and the makefiles
don't chain together. :)
Thanks!

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

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
