Build failed in Jenkins: master-osmo-sgsn
by Harald Welte 24 Sep '18

24 Sep '18

Dear fellow Osmocom developers, During the past hours, we've been experiencing master-osmo-sgsn build failures. It coincides with some libosmocore.git vty change merge, it would be great if people working on this and/or osmo-sgsn can have a look. Thanks! -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

UE Unable to Obtain IP Address | Flooding error logs in OSMO-PCU

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.

OsmoCon 2018 draft schedule announced
by Harald Welte 16 Aug '18

16 Aug '18

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 -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

SGSN TTCN3 update
by Alexander Couzens 07 Aug '18

07 Aug '18

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 -- Alexander Couzens mail: lynxis(a)fe80.eu jabber: lynxis(a)fe80.eu mobile: +4915123277221 gpg: 390D CF78 8BF9 AA50 4F8F F1E2 C29E 9DA6 A0DF 8604

Data Rate of EGPRS is Too Low
by XINKE ZHANG 28 Jun '18

28 Jun '18

Hi all, I have set up the EGPRS network using software bundles (osmo-nitb + osmo-bts-trx + osmo-trx + osmo-pcu + osmo-sgsn + openggsn) based on the USRP B210 platform. Now the cell phone can connect to the EGPRS network, but the network is not stable and the data rate is too low (only about 8kbs). Is this data rate correct? If not, could you pls send me some working config files? Thank you. Best Regards, Xinke

GPRS doesn't work
by weng alexa 25 Jun '18

25 Jun '18

Hi all, I set up the EGPRS network using software bundles (osmo-bts-trx + osmo-trx + osmo-pcu + osmo-sgsn + osmo-ggsn + osmo-bsc + osmo-msc + osmo-hlr) based on the USRP B210 platform. Now the cell phone can connect to the EGPRS network, but the phone has no IP address. All the config files are in the attachments, could you help we find what's wrong?

osmo-pcu build failures on Debian 8.0
by Harald Welte 06 Jun '18

06 Jun '18

For quite some time, osmo-pcu has been causing build failures on Debian 8. You can find a build log e.g. at https://build.opensuse.org/package/live_build_log/network:osmocom:nightly/o… The visible sign is that for some reasson there are additional log lines present in the output of our unit tests, like: [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) downlink acknowledge [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) Final ACK received. [ 127s] +DL packet loss of IMSI= / TLLI=0xffeeddcc: 0% [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) changes state from FLOW to WAIT RELEASE [ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=WAIT RELEASE EGPRS) starting timer T3193 [release (DL-TBF)] with 0 sec. 0 microsec, cur_fn=0 where the "+" is the unexpected additional line. Does anyone have any information about why that is? I don't see any related changes recently. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

GTP-U support for a UE with multiple bearers (LTE)
by Shashank Prasad 18 Apr '18

18 Apr '18

Hi, I just started exploring the GTP-U module (maintained in the kernel) for LTE. In LTE, a UE can be associated with multiple bearers. This implies that an MS IP address can be associated with multiple TEIDs (one for each bearer). Based on browsing the kernel GTP implementation[1], it looks like the GTP-U (maintained in the kernel) can only support 1 TEID per MS IP address. In which case, the GTP implementation, as is, may NOT be usable by LTE modules. Is this a correct interpretation? - Shashank [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/plain/dr…
