Mergin meas_json to master
by Sipos Csaba 12 Dec '15

12 Dec '15

Dear Alexander, I started to write the Wiki page for Meas_web. During this I just realized that because of some outstanding merges the installation of this tool is painfully complicated. In order to make things easier, I suggest to merge the meas_json part into OpenBSC master: http://cgit.osmocom.org/openbsc/log/?h=achemeris/meas_json Regards, Csaba

Re: OpenBSC on CalypsoBTS without voice

Hello, Harald, thanks for the answer. first of all, CalypsoBTS is not an active / maintained / stable solution > but more lik an (mindbogglingly amazing!) Hack. Yes, I know that CalypsoBTS is not stable solution. But currently I am a student and I have no so much money to buy anything more powerful. Furthermore, I am interested in this for research purposes only, not for creating public land mobile networks. As you are the first person to report using the code to this list for > quite some time, it would be great if you had some time to re-base, test > and submit it. As I previously said, I also tested master branches. Here are the results: * When I start OsmoBTS I often see this message in OpenBSC log: "Lost some E1 TEI link: X X" from bsc_init.c. In this case my MS can not connect to the test network and I have to restart OsmoBTS until this message will no hide. * When the Location Update process I always see this error: "input/ipaccess.c:277 Bad signalling message,sign_link returned error". But a phone successfully registers in the network. * SMS, USSD and Silent SMS works fine. * When TS1 assigned TCH/H I can call to another ms or LCR. DTMF works. * When TS1 assigned TCH/F I can use FR codec and call to LCR. * PDCH does not work on this BTS. * RRLP works. * ISMI detach works but as in case of Location Update I see "Bad signalling message..." error. * It seems, the network works more stable when battery capacity is 100% and backlight is disabled. If I understood correctly, osmobts-trx was just moved from obsolete repository to the master. Now I am reading the source code and trying to fix this bugs. I have one thing in my mind for a long time. Is it possible to serve a PDCH lchan on TS1 instead of TCH (in case of this "powerful" BTS)? I have tested OsmoSGSN+OpenGGSN with one PDCH channel on TS1, but it did not work. With best regards, Яницкий Вадим. 2015-12-06 18:14 GMT+06:00 Harald Welte <laforge(a)gnumonks.org>: > Hi Vadim, >> >> first of all, CalypsoBTS is not an active / maintained / stable solution >> but more lik an (mindbogglingly amazing!)

The test suite for libosmocore fails on big-endian architectures
by Ruben Undheim 11 Dec '15

11 Dec '15

Hi, While building the package for Debian, apparently there is a problem related to big-endian architectures. Please see the logs here: https://buildd.debian.org/status/fetch.php?pkg=libosmocore&arch=powerpc&ver… and https://buildd.debian.org/status/package.php?p=libosmocore It is related to the test case for smscb and the struct gsm341_ms_message: +++ /«PKGBUILDDIR»/tests/testsuite.dir/at-groups/7/stdout 2015-12-05 15:51:53.463182812 +0000 @@ -1,4 +1,4 @@ -(srl) GS: 1 MSG_CODE: 1 UPDATE: 0 +(srl) GS: 0 MSG_CODE: 256 UPDATE: 1 (msg) msg_id: 1293 -(dcs) group: 1 language: 0 +(dcs) group: 0 language: 1 (pge) page total: 1 current: 1 7. testsuite.at:45: 7. smscb (testsuite.at:45): FAILED (testsuite.at:48) Could you please suggest how we should fix this so that the package also can build for powerpc and other big-endian architectures? Thank you very much in advance. Ruben

osmo-bts / osmo-pcu profiling results
by Harald Welte 10 Dec '15

10 Dec '15

Hi all, I've been doing some profiling on osmo-bts recently (on sysmobts hardware, which has only a relatively slow ARM926 CPU core), and the two things that show up most are: * msgb_alloc() -> talloc_zero() -> malloc this can be alleviated somewhat by using talloc pools. For some reason the pools don't remove all of the malloc() calls. * vfprintf() and friends, from logp() statements. The sad part is that calls like gsm_lchan_name() are of course executed beefore the call into logp(), at which point the vfprintf/sprintf/... for arguments has already been executed, and only the last/final one hasn't happened yet. Here we can do two things: Calls like gsm_lchan_name() don't need to happen all the time, as the lchan name is static and can be generated once at the time gsm_lchan is created. I implemented that in osmo-bts (and openbsc, as it's from gsm_data_shared). The second idea would be to expand the LOGP() macro a bit in a way to ensure the the checking whether the log line is enabled _before_ the arguments (and thus associated function calls) are evaluated. Any ideas on that? After a brief look at osmo-pcu profiling, it looks like in the attached picture. We cannot do much about the __copy_to_user_std, do_select and core_sys_select, as those are kernel side. However, there again we see vfprintf and friends, mostly via gprs_rlcmac_tbf::name() - and of course the msgb_alloc() and msgb_free() going through talloc and finally malloc. So the same strategies as above could (and probably should) be applied to osmo-pcu.

FYI: merge of gtphub
by Neels Hofmeyr 08 Dec '15

08 Dec '15

Hi list, I'm merging the last commits from the neels/gtphub branch to master (Holger agrees). I will direct my attention to other topics for the time being -- we're waiting for a live testing setup. ATM, I would see gtphub's maturity as "alpha": I believe it works as intended, but all testing so far, even though done with real equipment, was in a controlled test environment. If anyone would like to give it a spin, we'd appreciate any feedback. ~Neels -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Holger Freyther, Harald Welte

OpenBSC on CalypsoBTS without voice
by Вадим Яницкий 06 Dec '15

06 Dec '15

Hi all! Following wiki I am trying to launch OpenBSC on CalypsoBTS (two OsmocomBB phones) with speech support. I compiled libosmocore, libosmo-dsp, libosmo-abis and jolly/trx branch of OsmocomBB with transceiver support. Then I compiled opencore-amr, Sip-Sofia, oRTP for LCR. Then I compiled OpenBSC, OsmoBTS (with osmobts-trx) and LCR. OsmoBTS configured to use two timeslots only (*slotmask 1 1 0 0 0 0 0 0*) and it uses *TS0 as CCCH+SDCCH4* and *TS1 as TCH/H*. Here is some strings from my openbsc.cfg: bts 0 > codec-support fr hr amr > trx 0 > timeslot 0 > phys_chan_config CCCH+SDCCH4 > hopping enabled 0 > timeslot 1 > phys_chan_config TCH/H > hopping enabled 0 > When I use jolly/multi-trx branch of libosmo-abis, jolly/testing branch of OpenBSC and jolly/trx branch of OsmoBTS my network works very unstable. When I try to make voice call sometimes it falls with message "*No resources for TCH/H*". Russian language in SMS is not supported. I think it is because this branches are obsolete. I tried to compile everything again but used master branches, and it worked much better! Now everything works as well. But when I call to 995 or 993 numbers of LCR I hear nothing. :( In OpenBSC console I see: > <0004> abis_rsl.c:1465 (bts=0,trx=0,ts=1,ss=0) Activating ARFCN(806) SS(0) > lctype TCH/F r=CALL ra=0x43

PCU <---> SGSN protocol trace
by Sipos Csaba 05 Dec '15

05 Dec '15

Dear list, I just appear to have a strange UE behavior where the UE tries to Attach (both CS and PS), the Osmo-SGSN sends an Attach accept, but the UE never responds with an Attach complete, instead after 10 seconds it tries to re-attach. I had an issue quite similar like this earlies where the UE requests for some IEs or the SGSN sends soething the UE don't like. The point is, I would like to do protocol trace between the SGSN and the PCU, and I managed to see the traffic with Wireshark, but it was not able to dissect/recognise the protocols over the UDP layer. Can someone please help me how to configure Wireshark to be able to dissect the involved protocols? Thanks! Csaba
