Hello everybody,
My name is Niko, and it's my first post on mailing list.
Is it possible to use OpenBSC together with Huawei BBU3900, or Ericsson
RBS6601?
Thanks in advice
Niko
Hi,
I am new to this list.
I use ubuntu 14.04.02. I am trying to configure/compile osmocom-bb.
I have a few questions and problems:
According to the src/README.building file, I should get the arm toolchain
from gnuarm.com
This should be updated, gnuarm.com doesn't have any downloads any more.
Instead I installed gcc-arm-linux-gnueabi from ubuntu reps
1) normal gcc seems to support x-compiling for arm CPUs. Why not use that?
2) Your stock Makefile tests for CROSS_HOST against arm-elf-gcc. This
should be updated to test also against arm-linux-gnueabi-gcc from
gcc-arm-linux-gnueabi package
3) configure warnings:
configure: WARNING: unrecognized options: --disable-tests, --disable-tests.
Should be disabled if not supported any more
checking for arm-linux-gnueabi-mt... no
checking for mt... mt
configure: WARNING: using cross tools not prefixed with host triplet
Is this a problem?
4) configure asks for libosmovty. Despite listed, couldn't find it under
osmocom libraries any more:(
Where can i download it from?
TIA,
Nikos

Hi
How to implement RRLP with Openbsc ? I have read that it can be done
through Osmocom-LCS but it gives error on compiling.
In short how to implement osmocom-LCS with openbsc ?
Osmosom-LCS is not getting compiled !!!
Thanks.
Hello folks,
I have a strange behavior when the a MS send a Location Update, it is often
rejected.
I think the the problem is the "Rx GSUP LU Result without LU in progress"
(see log further).
It's weird because in the point of view of the HLR it seems OK :
- message 0x04 Update Location Request followed by 0x10 Insert
Subscriber Data Request
- message 0x12 Insert Subscriber Data Result followed by 0x06 Update
Location Result
Is anyone experiencing the same problem?
I will investigate in the code to see if I found something with the state
machines or timers, if I found more detail, I will post them.
Have a nice day,
Antony

Hi!
In case anyone wants to analyze GSUP protocol traces of Osmocom networks: The
related dissector has just been merged mainline two days ago:

Dear list,
I'm having trouble using the A5/3 encryption in my setup. A5/1 works perfectly fine [attachment a5_1.pcapng]. As soon as I switch to A5/3 and e.g. send an SMS, the last valid message I see in the Wireshark traces of the GSMTAP of osmo-bts-trx is the Ciphering Mode Command requesting A5/3. After that, several messages arrive at the bts, but it seems like it can't make any sense of them. The MS repeatedly tries to send the SMS but never succeeds [attachment a5_3.pcapng]. Both MSs are connected to the same bts.
According to the Classmarks of all MSs, A5/1 as well as A5/3 are supported.
This is my Setup:
- USRP N210
- osmo-trx
- osmo-bts-trx
- osmo-nitb
- osmo-pcu
- osmo-sgsn
- osmo-ggsn
I'm using a Debian 9 VM and tried both the packages from osmocom-latest as well as osmocom-nightly.
The MSs I've tested are two Nexus 6 and one Samsung Galaxy S I9000. All three with sysmocom nano USIMs.
Could the decryption at the bts be incorrect? Has anyone tested/used it recently?
I'll be happy to provide additional information if needed.
Thanks,
Jan

Dear fellow Osmocmo developers,
for many months it was required to cherry-pick a "HACK" patch to make
the BSC tests work, presumably to work around a bug in libosmo-abis, see
https://osmocom.org/issues/2718
As it turned out, libosmo-abis was not wrong, but my IPA_Emulation.ttcn,
so it was good to not merge that "HACK" and keep it out of master.
In Change-Id: I6d9eaf0d69457caacc03b9049a8bc57976480617 which was just
merged to osmo-ttcn3-hacks master I have fixed that bug in
IPA_Emulation.ttcn, so now the unmodified master of osmo-ttcn3-hacks
will run fine.
I'll remove the cherry-pick from our Dockerfiles, but please do make
sure you also stop using it in your local clones/branches/scripts.
