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,
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,
Today I'm working on updating my NuRAN unit with the new osmo stack in
order to try to reproduce the same behavior of old osmo-nitb we use in
production in Rhizomatica (with subscriber_create_on_demand feature on).
I'm writing just in case someone already put online a set of config
files with the parameters needed by such behavior set?
; )
ps: I have the new splip stack working fine here, I just need to modify
my setup with new features to support subscriber_create_on_demand.
Best regards,
Rafael Diniz
Dear all,
I've been asked by a number of pepole about a possible Osmocom village at the
CCC Camp 2019. I personally didn't really have any plans, but given related
e-mails and "encouragement" I went ahead and registered an "Osmocom Village",
see
https://signup.c3assemblies.de/assembly/3b8f7aa2-95d5-4c44-aadc-de8f2680e9c3
I also created a wiki page (as nobody else did, despite earlier discussion on IRC,
SCNR) for coordinating related efforts at
https://osmocom.org/projects/osmo-dev-con/wiki/CCC_Camp_2019
One of the bigger questions is about having a tent as well as some tables/benches
to sit on and work. The Camp orga team nas been negotiating rates with a tent
rental company, but to be honest I'm rather surprised by the extremely steep
pricing. The smallest possible tent (6m x 3m) would cost 825 EUR. I'm not
sure we want to raise that amount of money? Even if we'd be 10 people sharing
it, its still 82.50 EUR per person. And that excludes any tables/chairs.
I'm attaching the relevant parts of a mail from the assemblies orga team FYI.
Please note there also is some kind of fragmentation / overlap with the
team planning to run the GSM/3G networks at the camp, see Lynxis'
related post at
https://lists.osmocom.org/mailman/private/osmocom-event-orga/2019-June/0003…
It's questionable whether it makes sense to have tow distinct
'villages', but given that e.g. I don't know anyone of that singularity
city, I'm not sure if we'd either be welcome there, nor whether we'd
want to associate us with them? Also, while the GSM network operation
for sure has good reasons to mingle with the POC and whatever facilities
they have, I'm not sure if the wider Osmocom community attendees
unrelated to the GSM network operation wouldn't just be a
disturbance/nuisance.
In the end, to be honest, I personally do not feel I have the time and
mental capacity to take on any additional tasks in terms of organizing
anything. I just created the entry in c3assemblies as I was asked to,
and I similarly created the related mailing list and wiki page.
So please, anyone interested in making an Osmocom village happen one way
or another, step up [and continue this discussion on the
camp2019-village(a)lists.osmocom.org mailing list, without crossposting
everywhere else :)
Regards,
Harald

Hello Vadim,
I'm working on the TTCN3 tests for OsmoPCU. Harald told me, that there
are a few tests existing tests (such as TC_ul_tbf), that had been
developed with osmo-bts-virtual/virt_phy.
He also said that since there is trxcon/fake_trx nowadays, it would be
better to use that instead, if it supports PDCH. From a quick "git
grep", it looks like PDCH is supported in trxcon.
What do you think, should it work well enough to do the switch?
Thanks,
Oliver

Hello All,
I am working on get OpenBSC connected to a 3rd party MSC, I read from the
Osmo document that I can use the bsc only mode and the osm-bsc instead of
the osmo-nitb.
Currently I had osmo-trx-uhd, osmo-bts-trx, osmo-bsc, and osmo-stp
configured and and running, but I see a lot of below error logs in the
osmo-stp console:
```````````````````````````

Can anyone identify what is the issue here?

Hi!
Four builds ago, from build 585 onwards, we are seeing massive regressions
in the BTS_Tests.ttcn test suite on osmo-bts master:
https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-bts-test/test_resu…
I think this matches roughly when the TRXDv1 protocol changes were merged,
it would be great if anyone making changes to osmo-bts or the test suite around
July 21/22nd could investigate what's happening here.
Tests against osmo-bts-latest are doing fine, so I think we can exclude a bug
in the test suite.
Thanks + Regards,
Harald

Hi all,
I'm writing some tools for using with HF radio and SDR modems [1], and
I'm using multi-threaded architecture. Do you know the status and/or
which branch should I use of libosmocore in a multi-threaded application?
