Hi Community,
We tried to used the GPRS capability of OSMOCOM.
Installation and configuration were based in the URL provided below:
https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_I…
We successfully installed the needed elements to run GPRS and we were able to run the following:
osmo-msc
osmo-stp
osmo-hnbgw (optional)
osmo-ggsn
osmo-sgsn
osmo-mgw
osmo-bsc
osmo-trx-uhd
osmo-hlr
osmo-pcu
UE were able to camp but IP Address is unavailable (checked it under Settings > About Phone > Status)
No session / request coming in the OSMO-SGSN.
We are also flooded with this log in OSMO-PCU:

Dear Osmocom community,
the first schedule of the 2018 incarnation of OsmoCon 2018 has been announced,
see http://osmocom.org/news/99 for the announcment and
https://pretalx.sysmocom.de/osmocon2018/schedule/ for the actual schedule.
At OsmoCon, we are not targetting developers, but more the wider community
and Osmocom users. It would be great to meet many of you and hear more
about your relation to Osmocom.
Tickets are available from https://pretix.sysmocom.de/sysmocom/osmocon2018/,
and until August 31st the early bird discount still applies.
For those with a community / "just for fun" background and no employer
that would cover the ticket, we have a number of subsidized community discount
vouchers available. See the OsmoCon 2018 wiki page at
https://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2018
for more information.
Looking forward to meeting as many of you as possible in roughly two
months from now,
Harald Welte

Hi,
I've pushed my SGSN Branch "attach fsm" where I reworked the Attach Request into an FSM together with a TTCN branch (replacing unit tests) to gerrit.
When both branches applied upstream, we're up to 42 tests.
However these 4 test cases are still open:
pass->FAIL SGSN_Tests.TC_attach_pdp_act_deact_mt_t3395_expire => TEID wrong. Cleaning up the internal SGSN seems to fail.
xfail SGSN_Tests.TC_attach_gsup_lu_timeout => HLR interaction
xfail SGSN_Tests.TC_attach_gsup_lu_reject => HLR interaction
xfail SGSN_Tests.TC_attach_second_attempt => HLR interaction
Best,
lynxis
