GPRS doesn't work
by weng alexa 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? Thanks sincerely All of the osmo-pcu's log is like the below: 20180625043250233 DRLCMACMEAS <0007> gprs_rlcmac_meas.cpp:183 DL Bandwitdh of IMSI=xxxxxxxxxxxxxxxx/ TLLI=0xb6ccf813: 190 KBits/s

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?

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…

== OsmoCon 2018 == OsmoCon (Osmocom Conference) 2018 is the technical conference for Osmocom users, operators and developers! We are happy to announce the date of OsmoCon 2018. It has been scheduled on October 18 + 19, 2018 and will happen in Berlin, Germany. For the second time, the Osmocom Conference brings together users, operators and developers of the Osmocom Open Source cellular infrastructure projects, such as OsmoBTS, OsmoBSC, OsmoSGSN, OpenGGSN and others. Join us for two days of presentations and discussions with the main developers behind Open Source Mobile Communications, as well as commercial and non-profit users of the Osmocom cellular infrastructure software. You can find some initial information in our wiki at http://osmocom.org/projects/osmo-dev-con/wiki/OsmoCon2018 which will be updated as more information becomes available. == Call for Participation == We're also at the same time announcing the Call for Participation and call on everyone with experiences to share around the Osmocom member projects to submit talks, workshops, discussions or other proposals. You can find the CfP at https://pretalx.sysmocom.de/osmocon2018/cfp We are particularly looking for contributions about: * updates on features/functionality/status of individual Osmocom projects * success stories on how Osmocom projects are deployed in practice * migration from OsmoNITB to the post-NITB architecture * tutorials / workshops on how to setup / analyze Osmocom projects * statistics, reporting, operations aspects of Osmocom projects * third-party open source utilities to be used with Osmocom projects Looking forward to meeting many existing and new Osmocom users at OsmCon this October!

Data throughput issues. Increasing throughput.
by Dave Ellis 05 Apr '18

05 Apr '18

Hi, I need to increase the throughput through the GTP tunnels to around 9Gb/s. I have two servers and they are connected using two GTP tunnels over a Mellanox 25Gb/s link. Via the tunnels I am seeing a total of 4.2 Gb/s to 4.5 Gb/s using iPerf. If data is sent without the tunnels I see a throughput of around 24.5Gb/s. I have tried various tweaks to improve the throughput over the GTP tunnels and have only made marginal gains. I have tried iPerf 2.0.9 and iPerf3 and see the same results. Wireshark shows the iPerf MTU is reflected in the pcap logs. I have tried changing the txqueuelen on the tunnels, changing osmo-ggsn niceness, network buffer sizes etc. The restriction seems to be osmo-ggsn as that is taking up to 92% CPU on one of the cores when the throughput tests are running. I'm hoping I have made a mistake in the configuration of OsmoGGSN and sgsnemu. -- The servers are running Ubuntu 16.04 desktop. 16GB RAM - 12.6GB free when running throughput tests. Intel E52620v3. Mellanox MCX516A-CCAT network adapter. 25Gb direct attach copper connecting the two servers OsmoGGSN version 1.1.0.75-3e44-dirty.

Interfering with the GTP-u Kernel module
by Thomas Boros 16 Feb '18

16 Feb '18

Hello, I would like to implement a command line tool, which will be able to open / close , read / write to gtp tunnels. I was able to install the libgtpnl library, but due to lack of documentation I have no idea where to start. Is there some sort of documentation available for this library? I need to be able to create and delete tunnels without the GTP-C communication, so just basic command line tool like create-gtp-tunnel + arguments like IPs, version and teid. The GTP-U tunnels must be kernel based. I have the latest kernel with the gtp kernel module loaded. Any help is appreciated. Thank you, Tomas

Problem when building OsmoSGSN
by XINKE ZHANG 16 Feb '18

16 Feb '18

Hi all, I built OsmoSGSN with the these following instructions. <build instructions> git clone git://git.osmocom.org/osmo-sgsn cd osmo-sgsn autoreconf -fi ./configure --enable-iu make -j5 make check make install sudo ldconfig <build instructions> And no error came out during building process, but no “osmo-sgsn” executable was found. Pls help me. Thank you in advance. Best Regards, Xinke

sgsnemu: no outgoing GTP-U in "createif" mode
by Viktor Tsymbalyuk 09 Feb '18

09 Feb '18

Hello, I tried to run sgsnemu in "createif" mode - transfer traffic via tun interface. tun interface created and routing too. But there are no outgoing GTP-U from test machine. (in my scenario sgsnemu on separated server). From gdb it looks, that in cb_tun_ind function ipm->pdp is 0x0, as result gtp_data_req(gsn, ipm->pdp, pack, len); not running. After changes like below, it's start working. Does I correctly understood internal logic? diff --git a/sgsnemu/sgsnemu.c b/sgsnemu/sgsnemu.c index 630733b..cf4aa44 100644 --- a/sgsnemu/sgsnemu.c +++ b/sgsnemu/sgsnemu.c @@ -1462,7 +1462,7 @@ static int create_pdp_conf(struct pdp_t *pdp, void *cbp, int cause) free(forwarding); } - ipset((struct iphash_t *)pdp->peer, &addr); + ipset(iph, &addr); state = 2; /* Connected */ If need more test details, please let me know. -- Viktor
