HI.
Pardon the cross-posting, I'm not sure where this question really belongs.
I've been trying to wrap my head around how PDTCH/PACCH/PTCCH activation
works. In osmo-bts-sysmo/oml.c there is pdtch_sapis[] which defines what
got to be activated both in DL and UL directions. Right now it's PDTCH
(UL & DL), PTCCH (DL) and PRACH. Note that PACCH (DL) and PTCCH (UL) are
commented out.
Yet I see code dealing with PACCH in osmo-pcu and corresponding log
messages.
So the question is - how does this works? The PACCH seems to be used so
it's somehow activated but apparently not the same way as PDTCH.

Hello All,
We are testing GPRS/EGPRS functionality in Multi-TRX(2 TRX) configuration for 2MS and we observed that both the MS are always assigned resources in TRX0. It seems like there is no load balancing done
Across the TRXs.
Similar issue "Bug #1775 LC15: No PDCH allocation across two TRX" is raised on Multi-TRX and its status is "In Progress". Please let us know if any updates on this issue.
Thanks and Regards,

Hello All,
We have executed profiling test of two versions of algorithm for decoding compressed bitmap of EPDAN.
>From the results , we see that performance is better in Tree based decoding (Version2 as given below )
Version 1: Bitmap based decoding as present in current master branch ( Function name osmo_t4_decode )
Version 2: Tree based decoding ( Function name decompress_crbb , as proposed in patch "Decompress the CRBB bitmap using tree based approach"<http://lists.osmocom.org/pipermail/osmocom-net-gprs/2016-March/000525.html> )
A sample bitmap taken from a real mobile log is used for the test.
Host execution: Time taken to decode (micro seconds)
Version 1: (Bitmap based decoding) : MIN -17 MAX -19 AVERAGE -17.9
Version 2 (tree based decoding): MIN -4 MAX -13 AVERAGE - 5.2
Target execution: Time taken to decode (micro seconds)
Version 1: (Bitmap based decoding) : MIN -277 MAX -583 AVERAGE - 353
Version 2 (tree based decoding): MIN -67 MAX -86 AVERAGE - 69.8

Dear Developers,
I have a question for you. As you might be knowing. there is a patch now
available for OVS for GTP-U support. When the developers of the patch
submitted it to add to the main branch of OVS, the OVS developers told the
following.
It doesn't look like upstream Linux has a GTP implementation. Because
our usual workflow is to get code upstream first, you should start by
submitting the kernel patches against net-next when that tree is open (I
don't follow netdev, so I have no idea when that is). Then, once the
GTP code is upstream, we can get it into OVS here.
So, is the upstream Linux having support for GTP now? I am asking this
because I am not certain about what upstream Linux means. If you say that
upstream Linux has support for GTP-U, then I can ask the patch developers
to port it for the latest version of OVS and add it to the main branch.
Best Regards,
Ashish Kurian

Hi All
I have added IPv6 support to OpenGGSN and if anybody is interested I will gladly make my patch available. It definitely needs more testing and perhaps a bit of cleanup, but currently it can do 4-in-4, 6-in-4, 4-in-6 and 6-in-6.

Hi
I’m Bjørn, I work for Telenor Digital. We’re running a live experimental network (called “loltel” :-) that is technically operating as a full stack MVNO (mobile virtual network operator), renting network access from Telenor Norway. It’s mostly but not exclusively based on open source components. When we started up about two years ago we considered using OpenGGSN, but couldn’t figure out how to get it into an operational state and we couldn’t find anyone to help us, so we chose a commercial vendor instead.
But today we’re again thinking of using OpenGGSN for an experiment, possibly in our live network. Are there anyone on this list with experiences either with running it in a live network, or with thoughts about how to do it / what would be necessary to get the job done? We’d love to have a discussion with you.
Hope to hear from you soon.
Best wishes
Bjørn

Hi all,
OpenGGSN has moved to gerrit today. Patch submissions shall go there now, no
longer to this mailing list.

Hi All,
I downloaded the tar ball release libgtpnl-1.0.1.tar.gz and un tared it.
Then I tried to build and install the package. But the command sudo
./configure is giving me the following error.
configure: error: cannot find install-sh, install.sh, or shtool in
build-aux "."/build-aux
Do you know what could be the reason for this error?
Best Regards,
Ashish Kurian
