I have a ip.access nanoBTS (version 165AU9012)v(37) and have been using it
with a very early version of OpenBSC (OpenBSC 0.01) and am now trying to
upgrade to the latest version downloaded from GIT (OpenBSC version
0.9.0.565-993d).
When I use the configuration that works on the old version, with this latest
version, I get the following error:
user@ubuntu:~/openbsc/src$ ./bsc_hack
<0005> bsc_init.c:1024
WARNING: You are running an 'accept-all' network on a BTS that is not

networks and should only be used in a RF shielded environment such as a
faraday cage!

Can anyone explain why I get this error and maybe send me a config that

Hi!
I've committed some changes to enable ipaccess-config to set static IP
address, netmask and gateway. A full command looks like this:
./ipaccess/ipaccess-config -U dhcp-enabled -S static-ip -S static-gw -i 192.168.100.222/255.255.255.0 -g 192.168.100.1 -r 192.168.100.120
This will
* unset DHCP client functionality
* set static IP address nvram flag
* set static gateway nvram flag
* set the BTS IP to 192.168.100.222 netmask 255.255.255.0
* set the default gateway to 192.168.100.1
* restart the BTS
Regards,
Harald

Hi Folks.
I always found it annoying to calculate the correspondending frequency
of an arfcn by hand or with the webbased arfcn calculator.
So i wrote a little program to do the work for me:

Maybe the one or other here on the list will find it useful.

Hi all,
I just pushed zecke/remove-use-count with two commits to almost complete
the split. This code allocates the "struct gsm_subscriber_connection"
dynamically and the follow on commit is removing the use_count and
releases a channel as soon as it is unused (no operation/transaction is
left on it).
I would like to land this code now and continue with:
-) Land some channel release changes from the On-Waves branch
-) Update the channel release documentation...
-) Start recreating the osmo-bsc...
-) Implement the assignment command and use it from gsm_04_08.c
and suddenly we can easily switch from very early to early
assignment...
Hello,
We have a working OpenBSC-LCR-Asterisk setup by now.
Sending SMS from one cell phone to another works perfectly after typing
"sms send pending" in the vty-console. Is it always needed to trigger
the sms-sending manually or is there a fixed intervall in which sms will
be transfered?
Still a problem exists. If we try to send a sms directly from the
bsc_hack_vty with "subscriber extension xxx sms send "TEXT"", the
bsc_hack crashes:

Hello,
I found some english lectures about communication by university Freiburg
(germany) as video:
http://itunes.uni-freiburg.de/uebersicht/podcast_content?id_content=48
e.g.
Protocols and technologies of telephone networks
ISDN network functions, introduction to GSM digital mobile
Extension of GSM overview
GSM data services
UTMS as the world wide 3G mobile standard
You can watch it online as flash or download a .mp4 file :)

Hi, List!
I found a bug in OpenBSC. If I try to change the name of a subscriber
using Telnet (command "subscriber ... name") I got an error, if the
name contains spaces (for example: first and lastname).
I found the problem and I wrote a patches.
I send it as attachment.
Greetings

It only does that when in an active dedicated channel (either a call
or a sms or some other transaction).
If you enable the debug for the DMEAS (either in the console or with
the -d option), you should see those reports.
Also, it sends reports only for neighbor cell of your network (as
specified in the BCCH SI messages).
Cheers,
Sylvain

Hi, List!
As I promise, here my patch, to solve the problem I explained on
18.06.2010.
I'm now sure, my patch is NOT responsible of the problem sending SMS,
then I'd like to submit it to the list.
Greetings

Hi, again!
I have another question, and this is: how can I measure the distance of
a mobile from a BTS?
I'm reading the book "Die GSM-Dm-Kanäle im Dialog" by Joachim Göller,
and I learned, that a mobile phone sends, about every second, a
MEASUREMENT REPORT to the station, where it is logged.
In this report the mobile sends the signal power of the cell, where
it is logged, and of other neighborhood cells.
With these signals, I can measure the distance of the mobile from my
cell(s).
But I don't understand how can I get this values using OpenBSC.
Can someone explain me how can I do this?
Thanks a lot!
