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.
So far three persons have indicated their interest to join
a meeting at my place.
Considering the time it takes to drive to my place, it
probably makes sense to have the meeting at the weekend
(either Saturday or Sunday) so that there is more time
for the meeting itself. I can suggest one of the following
dates for the first meeting, somewhere between 10:00 to
18:00 on each day:
25.8. (Sa) or 26.8. (Su)
1.9. (Sa) or 2.9. (Su)
8.9. (Sa) or 9.9. (Su)
So please let me know when you have time and also make
suggestions in which Osmocom topic you are interested
in so that we can have some sort of agenda for the
meeting to make best use of the time.
Best regards,
Dieter

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:

Hi everyone,
I have this 1 question: is it possible to have a complete communicating network with FakeBTS runing on 1 machine and all other processes on the other?
(I have asked this question earlier but have not received any answer as yet. can somebody please care to reply, its a little urgent)
Thanks and regards

Hi everyone,
I am trying to test Openbsc with the FakeBTS and I wanted to know if it is possible to run FakeBTS on one machine and all other processes ie osmo-nitb, gggsn, osmo-sgsn and osmo-pcu on another machine and set up communication among these?
Thanks and regards
Priyanka
Hi everyone,
During the installation of the softBTS the following error incurred:
root@ubuntu:/# aptitude install gnu-smalltalk osmo-st-openbsc-test
couldn't find any package whose name or description matched "osmo-st-openbsc-test"
while gnu smalltalk has been installed.
can somebody help me with this?
Thanks and regards

Hello,
At the University of Freiburg (Germany) we have two nanoBTS 1800 and a
nanoBTS booster 1800 for sale:
NanoBTS Modell 139: 1500 Euro
NanoBTS Modell 165G: 2500 Euro
NanoBTS-Booster 1800: 1000 Euro
The nanoBTS 139 needs to be unplugged if the software Open-BSC is
restarted. Most likely this is only a software problem.
Details for the booster are given here:
http://www.proximus.com.ua/Nano_BTS_high_power_GSM_booster.html
The NanoBTS-Booster package includes everything required:
- Booster
- Power supply
- 2x cable to connect to the nanoBTS (0,5 meter)
- 1x cable to the antenna (5 meter)
- 1x omnidirectional antenna. 3 dBd gain / 1800 MHz
The antenna is a high quality omnidirectional antenna from Procom
(cxl-1800-3).
Best regards

Hi everyone,
I am trying to test Openbsc without a BTS. I need your help as I am very new to Openbsc.
After doing the configurations for openbsc-multitrx.cfg file this is how I started the process:
cd openbsc/openbsc
src/osmo-nitb -c doc/examples/osmo-nitb/nanobts/openbsc-multitrx.cfg -C
And the output I received was:
<0019> input/ipaccess.c:925 enabling ipaccess BSC mode
DB: Database initialized.
DB: Database prepared.
<0001d> sms_queue.c:220 Attempting to send 20 SMS
After this I added a subscriber in the hlr and the subscriber was added in the output:
<0019> ipaccess.c:841 enabling ipaccess BSC mode
DB: Database initialized.
DB: Database prepared.
<001d> sms_queue.c:232 Attempting to send 20 SMS
<0002> gsm_subsciber.c:390 Expiring inactive subscriber Testing(ID 1)
After this I used the following commands on the osmo-nitb console and receive the following output:
Openbsc>show subscrber id 1
ID: 1, Authorized: 1
Name: 'Testing'
Extension: 9999999999
LAC: 0/0x0
IMSI: 404012345678903
TMSI: 0012D681
Pending: 0
Usecount: 1
Openbsc> subscriber id 1 send sms Hello
Openbsc> subscriber id 1 silent call start any
%subscriber not attached
Am I doing the right thing, are there some more configurations that I am required to do and is this the only output that can be achieved without a BTS?
Also the lac is being displayed as 0/0x0, is this how it should have been?
Please let me know, I really need help on this.
Thanks and regards

Hi,
Jean-Samuel and me developed an advanced handover algorithm for OpenBSC.
Before implementing it, we would like to get any feedback, so I decided
to post it in this mailing list. The document that describes the
algorithm can be downloaded at:
http://home.eversberg.eu/handover-algorithm-v2.3.pdf
Regards,
Andreas
Handover shall ensure that the mobile station is always on the best cell
during a call. This results in best speech quality and allows a lower TX
level (up-link) to save battery and reduce interference. Sometimes this
is not desirable, especially if a cell with large coverage becomes
congested after handover. In this situation it makes sense to balance
the usage between cells to prevent congestion. If a cell is congested,
one or several mobile stations need to be handovered to a different
cell, even if that cell is not the best cell for these mobile station.
In case that a mobile station needs to handover to prevent a loss of
radio link, it makes sense to handover it to a cell that is congested
afterwards. In this situation, a different mobile station on the
congested target cell must be handovered to a non-congested neighbor
cell, to solve or balance the congestion.
In order to negotiate used codec and TCH rate during call setup,
Immediate Assignment shall assign an SDCCH channel, if available. After
negotiation is complete, assignment to the available TCH slot is made.
