Help required for non-sync Handover
by Muhammad Awais Aslam 16 Jan '18

16 Jan '18

Hi, We have manged to decode the BSIC in dedicated mode which were not implemented before. Now we are working on the synchronize and non-synchronize Handover. Once we send the fake measurement report to the BTS we get a handover command from the network. That could be synchronized or non-synchronized. In case of synchronized hand over, without making any changes in the TPU clock offset and the frame number and frequency correction, we are able to complete the handover process most of the time. In case of non-synchronized handover, a physical info is required from the network when mobile station would send Handover access burst to the network before the timer expires but we never get physical info during this period. Here we are stuck. Changes: for non-synchronized handover we need to change the TPU offset and frequency correction offset and frame number parameters which we stored during the BSIC decoding. We set these values before we send handover access burst to the network but no success. Anybody who is working on the handover currently or in the past can discuss these things with me so we can figure out why we are not getting the physical info during the non-sync handover. I have also attached the main changed files with this email. I hope someone would give advice how to debug the issue. Regards M. Awais

stow fallout, problem in osmo-bts-sysmo build
by Neels Hofmeyr 16 Jan '18

16 Jan '18

In osmo-bts, we just have the configure flag --enable-sysmocom-bts, and don't pass a header include location. i.e. we expect the header files to exist locally. I'm a bit stumped on why introducing stow would cause this to break. IIUC stow should only affect the installed dependencies, while the sysmocom headers are just placed in a local dir? If we can't fix the osmo-bts build quickly, we'll have to revert the stow patch until that works. https://jenkins.osmocom.org/jenkins/view/master/job/master-osmo-bts/36/BTS_… The build scripts are (obviously) in osmo-bts/contrib/ and osmo-ci/scripts. Any help is appreciated. ~N

External USSD interface development
by Vadim Yanitskiy 16 Jan '18

16 Jan '18

Dear Harald, In this mail I would like to express my thoughts and ideas regarding to the 'external interface for USSD'. To provide some background for other mailing list members, who are not aware of this topic, I'll explain it in a few sentences. We already have an external interface for SMS - SMPP. But unfortunately, the same cannot be said about USSD. There is no built-in support of any interface, which could be used to handle USSD requests in a separate application. So, at the moment we only handle *#100# (own number request), which is implemented as a part of both OsmoMSC and legacy OsmoNiTB. And if one would like to implement additional USSD commands, it's required to modify and recompile the whole project :/ Fairwaves team already have some draft implementation for legacy OsmoNiTB, which relays on the libosmocore's GSM 04.80 API. And having the external interface in the mainline would be great not only for Fairwaves, but for the whole Osmocom project and its users. The problem is that the current libosmocore's GSM 04.80 API is not complete and requires some critical modifications, which of course cannot be integrated immediately. Moreover, this implementation doesn't follow Osmocom coding style, for example, unlike other functions, where return code rc = 0 means success, there it means error... So, first of all, we need to know, how many projects are using the current API, especially non-Osmocom projects. After that (taking it into account), it shall be decided: - Should we keep the old API / ABI and maintain all new features among with it. This way would force us to duplicate the existing code and use different symbols. Then the old API would continuously became deprecated... - Should we make all the critical changes in the current API (increasing the libosmocore version?). This way would break builds of dependent projects and would suppose fixing compatibility with the new API. But, at the same time, the implementation would be cleaner and closer to the specification, without any deprecated duplication... Personally, I prefer the second way. At the same time, I want to make the modification as much transparent as possible. Speaking about Osmocom projects, the only users of the GSM 04.80 API are OsmoMSC and legacy OsmoNiTB. Both projects utilize it for '*#100#' handling only :/ To be more convincing, let's look at the following code: #define MAX_LEN_USSD_STRING 31 struct ss_request { uint8_t opcode; uint8_t ss_code; uint8_t ussd_text[MAX_LEN_USSD_STRING + 1]; uint8_t transaction_id; uint8_t invoke_id; }; This is what the current API allows you to obtain from a SS-request (e.g. '*#100#') coming from user. And what's wrong here? - The 'ss_request' doesn't indicate a part of the library it comes from. Would be better to use 'gsm0480_ss_request'. - The 'ussd_text' length doesn't follow the specification, where USSD OCTET STRING length is 160 bytes. So, the amount of characters depends on used coding scheme. - The information about SS-message type, component type, text length and used DCS (Data Coding Scheme), etc. is missing. Despite it could be important for the external application. So, let's discuss together all the 'pros and cons', and decide together, how should we facilitate the external USSD interface development. With best regards, Vadim Yanitskiy.

osmo-bsc_nat dropped in unrelated patch
by Neels Hofmeyr 16 Jan '18

16 Jan '18

Hi dexter, reading a commit of yours apparently merged to osmo-bsc in November, I notice that you "secretly sneaked in" this: diff --git a/src/Makefile.am b/src/Makefile.am index d04f025..dd1ad3d 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -33,5 +33,4 @@ SUBDIRS += \ utils \ ipaccess \ osmo-bsc \ - osmo-bsc_nat \ $(NULL) in a patch that was supposed to "mgcp: use osmo-mgw to switch RTP streams". http://git.osmocom.org/osmo-bsc/commit/?id=39c609b7c924524172ad311bdf89f92b… So since we merged that patch, osmo-bsc_nat is no longer part of the osmo-bsc build. That's certainly not intended, is it? Confirm and please fix that. thx! ~N

USRP2 and OsmoTRX
by Rafael Diniz 16 Jan '18

Hi people, I'm doing some tests with an old USRP2 + RF900 daughterboard, and I get a very unstable system (with osmo-trx, osmo-bts-trx and osmo-nitb) - some phones can connect, some dont. I'd like to identify the problem - is it a bad GBit ethernet or the lack of a GPSDO connected to the 10MHz port?

osmo-trx test setup & convolve_test failures on different machines
by Pau Espin Pedrol 15 Jan '18

15 Jan '18

Hi everybody, as some of you may have noticed due to the generated noise in gerrit ml during last days, I have been adding some autotest setup to osmo-trx in order to have several tests being run during gerrit review. Since osmo-trx has some specific code built with NEON instructions, I also added some infrastructure to jenkin.sh to generate and use a prebuilt debian armhf rootfs so we can easily build and run tests using qemu-arm from our local workstations or from jenkins slaves, which will check that support for those architectures doesn't become broken. In order to set up the make check tests, I re-used existing tests and moved them to the tests/ directory. I also moved utils/convolvtest/main.c into "tests/Transceiver52M/convolve_test" [1] to become a test that checks "convolve_{real,complex}" APIs. I noticed, however, that this test prints slightly (or not that slightly) different outputs on different machine architectures, which of course make tests fail as it matches the exact values. So far the output is different in my x86_64 workstation, my i686 netbook (or i586 OBS host) and in my qemu-arm (armhf). As each machine uses different instructions sets, I indeed can understand that there appear small differences due to floating operations and rounding, but sometimes I can see relatively big difference between one implementation and the other one (eg 7.032490 vs 6.655972). I'm thinking about modifying the test to, instead of matching the output exactly, check that for each value in the vector it is similar to a value with a maximum epsilon distance from a reference vector. However, as I don't have any knowledge regarding the maths and theory behind the convolution codes, I must admit I am not sure which epsilon should I be using, or which should be the expected output for the test. It may perhaps make sense to have separate reference output for different architectures, I don't know. Can somebody shed some light on this topic? Any advise or hint is welcome. It would also be nice to have some tests for the "convert" API, which uses optimized instructions sets too. If somebody wants to provide those or any hint on how to implement them that's going to be handy. All the test infrastructure is merged now, only the patch adding the qemu part is not merged but already working in [2], I'll merge it tomorrow if nobody is angry with it. You can find related output for the test I was speaking of for different machine arch (x86_64, i686, arm) in [3] and [4].

Make docker rebuild if apt repository changes
by Harald Welte 13 Jan '18

13 Jan '18

Hi Neels, I've seen some discusion (unfortunately on the sysmocom internal jaberr room, not on a public osmocom channel) related to the docker based jenkins verification jobs as follows: ADD http://download.opensuse.org/repositories/network:/osmocom:/nightly/Debian_… /tmp/Release RUN apt-get update && apt-get install -y --no-install-recommends libosmocore-dev The "ADD" line will check if the "Release" file of the repository has changed. If yes, the cache will be invalidated, and the following line[s] will be re-run. If no, then the cache will remain. It's sub-optimal in that any change to the repository (even those that are unrelated to the packages used, [libosmocore-dev in this example]) will trigger an image re-build. But at least it will guarantee that any update to the libosmocore-dev package will trigger an image rebuild. See http://git.osmocom.org/docker-playground/tree/osmo-stp-master/Dockerfile for a real-world example Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Hello,I have some question, it just for curiosity! It's possible that a phone tell to the bts he did support only A5/0 encryption or it just only the BTS to command the ciphering !? and it is possible to do that for the osmocomBB !? Chears,

multiple log destinations
by Max 11 Jan '18

11 Jan '18

Hi. We have several kind of logs in libosmocore: 'log stderr', 'log file ...', 'log gsmtap' etc. Some of them are naturally singleton: you can't have 2 stderrs at the same time. Some are naturally parallel - it make sense to log different things into different files. What about "log gsmtap"? On the one hand sending to different hosts might make sense, on the other hand, the receiver can do filtering by itself. The current implementation does not allow multiple "log gsmtap" entries but the code is kinda unclear - I don't understand if that's intentional. So, is it a "bug" or "feature"? Shall we opt for greater flexibility and fix the code to enable multiple gsmtap log destinations? Shall we opt for simplicity and fix the code to make it clear that log gsmtap is singleton? Do you have any use-case in mind where multiple "log gsmtap" would come in handy? Do you foresee any problems arising from multiple "log gsmtap"working in parallel? N. B: this has nothing to do with recording bursts into .pcap, this is about sending log output using the same facility we use for recording frames sent/received over the air. The frame recording is used in OsmoBTS/PCU, the logging is used in all Osmo* projects. Just in case, the patch enabling multiple 'log gsmtap ...' is available in https://gerrit.osmocom.org/#/c/5747/ so you can give it a try. -- Max Suraev <msuraev(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 * Geschaeftsfuehrer / Managing Director: Harald Welte

project openbsc GSM-GPRS (not 3G),
by pierrejob＠netcourrier.com 09 Jan '18

09 Jan '18

Hi, In the context of a project GSM-GPRS (not 3G), I recovered the sources of the branch Master (github.com/osmocom). - osmo-pcu - openbsc (osmo-nitb, osmo-bsc, osmo-bsc-nat, osmo-bsc-mgcp) - libosmocore - libosmo-abis - libosmo-netif - liosmo-sccp - libsmpp34 - libosmo-ggsn - libosmo-sgsn (it seems not include in the openbsc's directory). Does the Library osmo-sgsn still need to be generated? because during the compilation only the module "osmo-gbproxy" is compiled. When I look at the Makefile (osmo-sgsn/src/gprs), the following lines are commented: #am__append_1 = \ # $(LIBASN1C_CFLAGS) \ # $(LIBOSMOSIGTRAN_CFLAGS) \ # $(LIBOSMORANAP_CFLAGS) \ # $(NULL) bin_PROGRAMS = osmo-gbproxy$(EXEEXT) $(am__EXEEXT_1) #am__append_2 = \ # osmo-sgsn \ # osmo-gtphub \ # $(NULL) #am__append_3 = \ # $(LIBOSMOSIGTRAN_LIBS) \ # $(LIBOSMORANAP_LIBS) \ # $(LIBASN1C_LIBS) \ # $(NULL) Let me know I you think there are mistakes. Thanks Pierre

question about 'lai & lac' paging
by Stefan Sperling 08 Jan '18

08 Jan '18

I am trying to fix issue OS#2754 "Paging on LAI not working". There are two tests related to this issue: 1) osmo-bsc/tests/bssap/bssap_test 2) TC_paging_imsi_nochan_lai in osmo-ttcn3-hacks/bss The first test is successful with my patch below. But the second test fails. It looks as if the MSC expects a response which is not delivered. I am unsure if the test has wrong expectations or if osmo-bsc is not sending a required response? The test's verdict is: Test case TC_paging_imsi_nochan_lai finished. Verdict: fail reason: Timeout expecting { msg_disc := { msg_group := RSL_MDISC_CCHAN (6), transparent := false }, msg_type := RSL_MT_PAGING_CMD (21), ies := { { iei := ?, body := { chan_nr := { u := { ch0 := RSL_CHAN_NR_PCH_AGCH (18) }, tn := ? } } }, { iei := ?, body := { paging_group := ? } }, { iei := ?, body := { ms_identity := { len := ?, payload := ? } } }, * } } Note that the existing ttcn3 test for the LAC case, which is already supported, and also covered by the bssap_test, fails in the same way: Test case TC_paging_imsi_nochan_lac finished. Verdict: fail reason: Timeout expecting { msg_disc := { msg_group := RSL_MDISC_CCHAN (6), transparent := false }, msg_type := RSL_MT_PAGING_CMD (21), ies := { { iei := ?, body := { chan_nr := { u := { ch0 := RSL_CHAN_NR_PCH_AGCH (18) }, tn := ? } } }, { iei := ?, body := { paging_group := ? } }, { iei := ?, body := { ms_identity := { len := ?, payload := ? } } }, * } } Any hints how to proceed?

osmo-python-tests py3 fail
by Neels Hofmeyr 08 Jan '18

08 Jan '18

Hi Max, in osmo-python-tests master, I did python2 setup.py install rm -rf build/ dist/ osmopython.egg-info python3 setup.py install which results in osmotestvty.py installed as py3, causing an encoding problem which I mentioned; py3 is a lot more than print() with braces, see the error log below. So in principle I still don't understand why the py2 scripts need to be made py3 compatible, and why I need to add 'from future' imports to py3 scripts now. There has to be a better way. About the need to rm the installation artifacts, there is no mention of it in the README. And even when I remove those, I still get py2 scripts installed as py3. So anyone is bound to get this error: " osmotestvty.py -p /n/s/osmo-dev/make/osmo-msc/../../src/osmo-msc -w /n/s/osmo-dev/make/osmo-msc -v confpath /n/s/osmo-dev/make/osmo-msc/../../src/osmo-msc, workdir /n/s/osmo-dev/make/osmo-msc Running tests for specific VTY commands test_history (__main__.TestVTY) ...
