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.

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 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

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

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 Devs,
I have successfully compiled and integrated osmoSTP with our product. I
have a question regarding to assotiaction establishment:
Currently we'll initiate the associtation establishment from our product
and STP will reply to our INIT message. Is it possible to start the
establishment from STP side? I haven't found any cli
command/configuration for this.
Thanks,
Laszlo
Dear Osmocom community,
I am using pysim to read values of ISIM. However, it just returns "None, None". And the aids of my SIM card is ['a0000000871002ff86ffff89ffffffff']. It seems does not have ISIM application on my SIM card.
How should I read values of ISIM?
Best regards,
Zishuai CHENG

Hi all,
I'm using pySim-Shell with a SysmoISIM-SJA2 as well as a SysmoUSIM-SJS1 and
on both cards I get quite a few "File not found" errors trying to access
different EFs. I'll use EF.NCP-IP as an example to illustrate the issue I'm
having below. My initial steps when I plug in the card are as follows:
1) ./pySim-shell -p0
2) verify_adm <adm1 key>
3) select ADF.USIM
Now when I run "dir" in ADF.USIM it lists a number of EFs I'm interested
in, including EF.NCP-IP. Since this requires service number 80 to be
available in EF.UST, I run "select EF.UST" followed by
"ust_service_activate 80". This runs without issue.
When I run select ADF.USIM now followed by select EF.NCP-IP, the card
returns a "File not found" error. So my questions are:
Is this file not supported on the SJA2 and SJS1?
Is there a way for me to add those files to ADF.USIM?
Is there a list of the known supported EFs of the SJA2 and SJS1? I looked
and couldn't find anything.
Thank you in advance!
Hi all,
I feel like I may be missing something about how SIM cards work here, but I’m unable to figure out how to load the ISIM application on my SysmoISIM-SJA2s, so I’m reaching out here for some help.
I started with pySim-shell and listed the directories under the MF directory and it shows only ADF.USIM, so I decided to use shadysim_isim.py to list out the applications on the card and was shown this:

The SysmoUSIM/ISIM manual pointed me to Annex E of 3GPP 101.220 which says the prefix of the ISIM application is A00..00871004.
So my questions are:
Am I missing something and the app is installed?
If not, is there a way to load and install the ISIM application?
Thanks in advance everyone.
Dear List
I am trying to use latest Osmo-core suite (osmo:stp,hlr,msc,bsc,bts,mgw)
with limesdr mini but facing issue as soon power rampup starts.
is there any stable release which I can use with limesdr mini
