I am following this instructions: https://discourse.myriadrf.org/t/limesdr-osmo-trx-no-work/1938/27 However, I am getting trouble starting tranceiver: *TERMINAL 1:* ronan@ronan-MS-N014:~/Downloads$ osmo-nitb -c openbsc.cfg -l hlr.sqlite3 -P -C <0005> abis_nm.c:2800 (bts=0,trx=0) Changing adm. state Unlocked -> Unlocked [vty] <001e> telnet_interface.c:104 telnet at 127.0.0.1 4242 <0005> bsc_init.c:465 WARNING: You are running an 'accept-all' network on a BTS that is not barred.

osmo-trx with USRP1 - libusrp vs. UHD
by Alexander Huemer 21 Jan '18

21 Jan '18

Hi! I played with osmo-trx today and tried to run it with a USRP1 that I have laying around, though to no avail. osmo-trx supports two kinds of devices, USRP1 via libusrp and UHD. libusrp was last included in gnuradio 3.4.2[1] from Dec 2013, it unsurprisingly does not build on a recent Linux distribution, due to API incompatibilities with boost. The USRP1 would theoretically be supported by UHD, though the device initialization code in osmo-trx explicitly treats it differently, see [2,3]. I found an old ML post[4] from 2015 that pretty much asks the same question but did not get an answer. Supposedly there is a simple reason why USRP1 is not driven via UHD in osmo-trx, but I don't know. Can somebody please enlighten me? Tom, maybe you? I would like to understand whether it is feasible to use an USRP1 with UHD for osmo-trx or one would have to go down the rabbit hole to build libusrp on a modern system. Kind regards, -Alex [1] https://gnuradio.org/releases/gnuradio/ [2] https://git.osmocom.org/osmo-trx/tree/Transceiver52M/UHDDevice.cpp#n512 [3] https://git.osmocom.org/osmo-trx/tree/Transceiver52M/USRPDevice.cpp [4] https://lists.osmocom.org/pipermail/openbsc/2015-January/000058.html

libosmocore wiki page and doxygen online documentation
by Pau Espin Pedrol 18 Jan '18

18 Jan '18

Hi, I was trying to find if the doxygen documentation is uploaded and publicly available somewhere in some web server. Google pointed me to this libosmocore wiki page: ftp://ftp.osmocom.org/api/latest/libosmonetif/ In there, there are several links to stuff like http://www.osmocom.org/doc/libosmocore/latest/html/, but I get access forbidden when trying to use that one. On the other hand, I found somewhere else a link to http://ftp.osmocom.org/api/latest/libosmonetif/html/ which seems to be working. Now the question is: which is the expected way to access the documentation? should "www.osmocom.org" work instead of having to use "ftp.osmocom.org"? -- - Pau Espin Pedrol <pespin(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

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
