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)
Autodetected card type fakemagicsim

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".
Best,

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

Hi all,
I was thinking about how to deal with the so called "evil twins" in the
distributed hlr, and also how to have a subscriber-create-on-demand
situation at the same time as a having an mslookup client.
The problem being that if we have mslookup client + fallback to
create-on-demand if no HLR responds for an IMSI, we will eventually
create a duplicate because the HLR that owns the IMSI is not contactable
at the time of an IMSI ATTACH attempt.
Anyway, just in terms of investigating the situation on my HLRs, I added
features [1] - so far, an ability to do a gsup.hlr lookup and not exit
on the first age:0 - so that I can see all HLRs that respond as having
the imsi in local HLR, and also to ask via mDNS for HLRs that have an
IMSI, but only if it's active on that HLR, that is, it has nam_cs/nam_ps
So this is really asking about what people feel about expanding the
D-GSM features in osmo-hlr, as I think it may be the case that
rhizomatica/TIC are the only people that use it?

Hi, is it possible to use soapyMultiSdr for osmo-trx? I have a hackrf one, which isn't full duplex, so my idea is to use the hackrf for tx, and something else for Rx. With soapymultisdr it is possible to use multiple devices as a single soapysdr device.
Dear Harald,
Sorry to spam the openbsc list with this, but if you (or someone) can
confirm if the Sgsn-emu part of Osmo-GGSN utilizing the kernel GTP
module or not, that would be lovely.
FYI, I was not able to pass more than 280Mbit and the sgsn-emu process
was maxing out a single core. Based on this I suspect that it does not
use the kernel GTP module. I have seen some commits that indicates
preparation work for this feature, but it is unclear at least to me,
if this was finished or not. In the Osmo-GGSN.cfg example config I can
see the config option for kernel GTP, but not in the sgsn-emu.cfg
example.
Regards,
Csaba
Hi Pau and Harald,
> So sgsnemu is passing use_kernel=false, which makes the lib skip gtp-kernel functions
That is nice, I can play with that part quite nicely and take a look
how the GGSN handles the switch between kernel and non-kernel GTP.
Thanks for that!
@Harald:
In gtpnl.h there is
int gtp_dev_create()
and
int gtp_dev_create_sgsn()
So it seems there is a different dev create for the SGSN mode. And in
the later one the role is set to "GTP_ROLE_SGSN"
int gtp_dev_create(int dest_ns, const char *gtp_ifname, int fd0, int fd1)
{
return _gtp_dev_create(dest_ns, gtp_ifname, fd0, fd1, GTP_ROLE_GGSN);
}
EXPORT_SYMBOL(gtp_dev_create);
int gtp_dev_create_sgsn(int dest_ns, const char *gtp_ifname, int fd0, int fd1)
{
return _gtp_dev_create(dest_ns, gtp_ifname, fd0, fd1, GTP_ROLE_SGSN);
}
EXPORT_SYMBOL(gtp_dev_create_sgsn);
I just need to find the relevant part is sgsn-emu to see where these
parts are invoked so I can make the modifications.
Regards,
Csaba
