Hi all,
After buying a super Sim Kit (16 in 1) from China, I tried the reader (green PCB inside a blue transparent plastic case with a blue LED) and SIM (identified as a fakesupersim) with pysim tool. However i am getting the following error:
/pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z 1234 -j 1 -t auto
Insert card now (or CTRL-C to cancel)

I checked mailing lists and haven’t found anybody who had similar problem with pysim. Also I have tried forcing different models of SIM, but nothing is working. Obviously I can remove this check from the script file (__init__.py in /pySim/transport), however somebody had a reason to put such condition there. I would like to ask if it is safe to remove that line of code and the purpose of that line of code.
Thanks a lot and best regards

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.
Hi all,
Just wanted to share an issue and a quick workaround I found for it in case
anyone else has the same problem. I believe a cmd2 update is causing
pySim-shell to fail. After installing it on a fresh install of Ubuntu
Server 20.04 and getting the following error when I run "python3
pySim-shell -p0":
>Using PC/SC reader interface
>Autodetected card type: sysmoUSIM-SJS1

If you run into this you can fix it by uninstalling cmd2 and reinstalling
cmd2 with "pip3 install cmd2==1.5".

A TS can be GSM_PCHAN_TCH_F_PDCH; those are the only ones for which we
send a PDCH ACT message.
We send a PDCH ACT message
- during init (CHANNEL OML's state changed to enabled -> send PDCH ACT),
- and upon channel release ack when pchan == GSM_PCHAN_TCH_F_PDCH.
So the question is, when we receive a channel release ack, could that be
the PDCH release and we switch PDCH right back on by accident? No, because
we only receive a chan rel ack when the *TCH/F* is being released.
That is because the PDCH release is initiated "internally" from the PDCH
DEACT, and thus this condition in common/rsl.c rsl_tx_rf_rel_ack() catches
on, which existed before dyn PDCH:
if (lchan->rel_act_kind != LCHAN_REL_ACT_RSL) {
LOGP(DRSL, LOGL_NOTICE, "%s not sending REL ACK\n",
gsm_lchan_name(lchan));
return 0;
}
In rsl_rx_rf_chan_rel() the rel_act_kind is set to LCHAN_REL_ACT_RSL, but
not in the rsl_rx_dyn_pdch().
This is analogous to the ip.access way -- the ip.access nanobts replies to
a PDCH DEACT with a PDCH DEACT ACK and doesn't send a separate channel
release ack.
Maybe we could set rel_act_kind to some new LCHAN_REL_ACT_IPAC_DYN_PDCH
for clarity? (But we shouldn't actually send a release ack, to stay
compatible.)
Even though it works as-is, we should indeed add another flag check:
- We do check the flags that no ACT/DEACT is already pending;
- And we do send a PDCH DEACT only if ts->flags & TS_F_PDCH_ACTIVE;
- But we would send a PDCH ACT despite ts->flags & TS_F_PDCH_ACTIVE.
This should never happen, but it would make sense to ensure that.

Hi,
I had a problem placing MO GSM calls from a Siemens S11E: The calls
were dropped immediately; Osmo-MSC reports "Cannot compose Channel
Type from bearer capabilities"
After investigating the SETUP request from the S11E, the phone does
not use octet 3a (no extension bit set in IE 3). Wireshark decodes the
radio channel requirement as "Full rate support only MS/fullrate
speech version 1 supported", so I added a condition to the gsm48_ie.c
function of libosmocore to include at least GSM FR in the list of
available speech_ver in case octet 3 has no extension.
Attached to this message are the Abis-IP PCAP traces of MO calls, and
the patch for gsm48_ie.c.

Lennart
Hi,
My name is Brackley Cassinga Form DRC, we run a community network called
pamoja net where we offer gsm services using osmocom open source software
and OC Base station.
Recently I have tried to install another base station as the same installed
but I could not find any resource guiding through all the steps to take to
run NIB on a base station.
I'm currently running Ubuntu and I will appreciate if you could guide me on
the installation of BSC,hlr,MSC , in order to run a basic gsm network.
Thank you. Regards

Hello GSM community,
As I keep working on my project seeking to build a new GSM network that
will be no worse in every aspect than the one which T-Mobile USA are
itching to shut down, I need a way to ferry the uplink voice stream
from the BTS to my "soft TRAU" in RTP transport, but do it in a way
that is semantically no-worse than what happens in the traditional
T1/E1-based architecture. As part of this no-worse-than-TDM desire or
requirement, I need explicit BFI markers - in other words, any time
there is a 20 ms window in which there is no good traffic frame to be
sent because the uplink is in DTX, because that frame was lost to bad
radio conditions or because that frame was stolen for FACCH, I want my
BTS to send an explicit BFI frame instead of gapping/pausing the RTP
stream.
But this "simple and innocent" desire which I just expressed then turns
into a perplexing question: just how would one represent an explicit
BFI marker in an RTP stream? In the case of AMR codec there is a
straightforward solution already provided for in the specs: simply
send a NO_DATA frame. But what about FR and EFR codecs?
For my own Themyscira Wireless deployment, I currently run with my own
non-standard extension to RTP transport format for FR & EFR, documented
here:
https://www.freecalypso.org/hg/themwi-system-sw/file/tip/doc/RTP-BFI-extens…
My solution works great for my purposes, and I am very happy with it.
However, in the spirit of seeking at least some unity and at least
some chance of patches being merged, I am making a due-diligence
attempt to understand how others have addressed similar problems, and
what competing solutions may already exist out in the wild.
Here is my specific question to the community, mostly the narrower
Osmocom community but perhaps also the wider GSM community: where did
the idea of an all-zeros frame representing BFI come from? In the
current osmo-bts-trx implementation (although not in any other osmo-bts
variants that I can see from the code) there is code that sends an FR
codec frame of 260 zero bits or an EFR codec frame of 244 zero bits,
both intended to signal BFI, under the following conditions:
1) The BFI condition exists for some reason other than the uplink
being in DTX, i.e., because the frame was stolen for FACCH or was
lost to radio errors, but the last frame was not a SID;
and
2) There is no ECU on the channel, or the ECU failed to provide a
substitute frame.
Irrespective of specific conditions though, the key point is that
someone, somewhere, at some point in time had the idea that an FR or
EFR codec frame of all zeros (260 or 244 zero bits, respectively)
should mean BFI. There is also a patch to gapk by Vadim, adding an FR
codec EFU function, that detects a frame of all-zeros and treats it as
BFI - but I am not able to tell if the very idea of such BFI
representation comes from Vadim, or if Vadim simply added the code to
gapk to work with what osmo-bts-trx puts out under certain conditions.
To put the question differently: does there exist any spec from ETSI or
from 3GPP or from any other non-Osmocom standards body that defines an
FR codec frame of 260 all-zero bits and/or an EFR frame of 244 all-zero
bits to mean BFI, or is this idea a pure Osmocom invention?
The only official specs I could find for coded speech transport within
RAN, between a BTS and a separate transcoder, deal with the traditional
T1/E1 environment, as in GSM 08.60 and friends. In those specs BFI is
signaled out of band: in GSM 08.60 TRAU frames there is a control bit
carrying BFI, and another control bit carrying TAF (important for
traditional Rx DTX handlers for FR & EFR), both outside of 260 data
bits, and there is NO special bit pattern (all zeros or otherwise)
within data frame bits themselves that would also signal BFI.
Therefore, based on what I see in GSM 08.60 and other specs for T1/E1
world, I get the idea that BFI is meant to be an out-of-band signal,
not in-band, and that an in-band bit pattern that signals BFI seems to
go against the spirit of ETSI and 3GPP.
But maybe the problem is that I was only looking at older specs, maybe
there is some newer spec from 3GPP or some other standards body written
for the newer world of IP transport that officially repurposes in-band
all-zeros FR and EFR codec frames to mean BFI - is there any such spec?
Moving from the realm of rhetorical questions to the realm of tangible
code, here is my latest creation in the realm of GSM codecs:
https://www.freecalypso.org/hg/gsm-codec-lib/
I will make another announcement when this code reaches the level of
completeness I am after, but as a short summary, I am making a
librified (turned into a library) version of the official EFR codec
implementation from ETSI (libgsmefr), and I have also written another
library of my own (libgsmfrp) that implements Rx DTX handler functions
for GSM FR, to be run as a pre-processor before passing frames to a
GSM 06.10 decoder, which is typically gsm_decode() from libgsm.
libgsmfrp is already integrated into my "soft TRAU" implementation in
themwi-mgw, and libgsmefr will likewise be integrated when it is
complete. (Right now only the decoder works in libgsmefr, the encoder
remains to be finished.)
Both libgsmefr and libgsmfrp have BFI handling functions which the
"soft TRAU" application needs to call when it receives a BFI marker
instead of a good traffic frame, but the question of how these BFI
markers should be represented in an RTP stream is outside the scope of
the library - instead my themwi-mgw application currently implements
ThemWi RTP-BFI-extension and calls the respective library functions.
I may be open to the possibility that I should not be inventing my own
RTP-BFI-extension and should instead use in-band frames of all-zeros
to represent BFI in FR & EFR, *if* there is some official spec from
3GPP etc saying so - but if that idea is an Osmocom invention rather
than 3GPP, then I am going to argue for my invented alternative RTP
representation instead. So which is it?

Hi all,
I am having an automake / libtool problem and don't know how to solve it.
In libosmo-pfcp, there is the pfcp_test binary, which obviously requires
linking libosmo-pfcp.so -- more precisely, it should NOT link the system
installed libosmo-pfcp.so, but the locally built one, libosmo-pfcp.a.
I try to accomplish this by:
pfcp_test_LDADD = \
$(LIBOSMOCORE_LIBS) \
$(top_builddir)/src/libosmo-pfcp/libosmo-pfcp.la \
$(top_builddir)/src/libosmo-gtlv/libosmo-gtlv.la \
$(NULL)
https://cgit.osmocom.org/libosmo-pfcp/tree/tests/libosmo-pfcp/Makefile.am
I am now adding a new optional IE to libosmo-pfcp, and I found that this does
not work as expected! The pfcp_test binary is linked to the previously
installed libosmo-pfcp.so in /usr/local/lib, instead of the proper, new version
from the build tree. I found out by getting an obscure ABI corruption error,
verified it by:
~/osmo-dev/make/libosmo-pfcp/tests/libosmo-pfcp
$ ldd .libs/pfcp_test
[...]
libosmo-pfcp.so.0 => /usr/local/lib/libosmo-pfcp.so.0 (0x00007f1b6bc00000)
libosmo-gtlv.so.0 => /usr/local/lib/libosmo-gtlv.so.0 (0x00007f1b6cc0a000)
[...]
As soon as I 'make uninstall' in libosmo-pfcp.git's root dir, this changes to:
▶ ldd .libs/pfcp_test
[...]
libosmo-pfcp.so.0 => not found
libosmo-gtlv.so.0 => not found
[...]
and then the test succeeds (because './pfcp_test' is actually a shell script
generated by libtool with linker magic referencing the libs built within the
libosmo-pfcp.git tree).
Now I am at a loss:
How do I tell automake (libtool) to keep out the system installed .so and
prioritize the libs in the build tree?
I can work around this for me by doing 'make uninstall' every time the
libosmo-pfcp ABI changes, but I would much rather fix this, so that users
rebuilding a newer version pulled from git don't run into this obscure problem.
I suspect that we may have a similar pitfall in many other osmo source trees,
because the Makefile.am *looks* like it takes care of this problem, but
actually doesn't.
Any ideas?
I am using:
automake (GNU automake) 1.16.5
autoconf (GNU Autoconf) 2.71
libtoolize (GNU libtool) 2.4.7
(Debian Unstable)
Thanks!

Hello Folks.
I am trying to get my head around on how java applet loading works for
sysmo-isim-sja2.
At first I used the following, updated example to compile a
HelloSTK2.cap: https://github.com/mrlnc/HelloSTK2.git
This works fine and it also loads fine on sysmo-usim-sjs2 using shadysim.py
Now I want to load the exact same file to a sysmo-isim-sja2.
I tried with shadysim_isim.py from
https://github.com/herlesupreeth/sim-tools:

As it seems gp.jar seems to work better than shadysim_isim.py.
Unfortunately I have no experience in java card programming yet, so its
difficult for me to tell where the error could be.
(When I run gp.jar once more it tells me "Error: STRICT WARNING: Package
with AID D07002CA44 is already present on card", I can also delete the
applet again, so apparently its kind of loaded...)
Is there anyone here who managed to load an applet to a sysmo-isim-sja2
and how?
best regards.
