[PATCH 0/6] Four minor fixes, "subscriber create" and subscriber's info formatting.
by Alexander Chemeris 04 Oct '13

04 Oct '13

This patch set is mostly minor fixes and clean ups, with the exception of the last two patches ("subscriber create" VTY command and a standard way for printing a subscriber's info). I would appreciate merging this patches to master, as I'm working onmore code which depends on them. Alexander Chemeris (6): Fix copy-paste error in console output in db_test. Fix typo ',' -> ';' at the end of a line. Fix typo in console output: "PEROIDOC" -> "PERIODIC". Slight clean up of the code in gsm340_rx_tpdu() and a fix for an unlikely, but possible memory leak there. Add "subscriber create" VTY command. Introduce a standard way for printing a subscriber's info. openbsc/include/openbsc/gsm_subscriber.h | 4 ++++ openbsc/src/libmsc/db.c | 2 +- openbsc/src/libmsc/gsm_04_08.c | 2 +- openbsc/src/libmsc/gsm_04_11.c | 7 ++++--- openbsc/src/libmsc/vty_interface_layer3.c | 27 +++++++++++++++++++++++++++ openbsc/tests/db/db_test.c | 2 +- 6 files changed, 38 insertions(+), 6 deletions(-) -- 1.7.9.5

How use TCAP instead of DTAP?
by Maicon Kist 03 Oct '13

03 Oct '13

Hi list, I want to integrate the OpenBSC with the Mobicents gateway. However, OpenBSC encapsulates the GSM MAP protocol in a DTAP header, while Mobicents expects a TCAP. The question is: Is possible to use the TCAP protocol in OpenBSC ? PS: Currently I am working with the USSD in OpenBSC. I performed some changes in the code and now we implemented the USSD request,facility and release-complete messages. In other words, now we are able to implement menus in USSD operations. Best Regards

[PATCH] bsc: Add control command to set timezone
by Jacob Erlbeck 02 Oct '13

02 Oct '13

This adds a per BTS control command 'timezone' which expects a value of the format '<hours>,<mins>,<dst>' or 'off' to set the value of bts->tz. It has the same functionality like the existing VTY command 'timezone' in network/bts.

Added patch to USSD iteration. Need help to continue.
by Maicon Kist 26 Sep '13

26 Sep '13

Hi list, I managed to add interaction to the USSD implemented in the OpenBSC. I attached a patch with the changes realized.The most important changes made are in the ussd.{c, h} files. I implemented the gsm0480_send_ussd_facility. Basically, I copied the gsm0480_send_response, change the GSM0480_OPERATION_CODE field value to GSM0480_OP_CODE_USS_REQUEST, removed the 2 bytes before this field and replaced the GSM0480_MTYPE_RELEASE_COMPLETE byte by GSM0480_MTYPE_FACILITY. Now, I don't know how to proceed. More precisely, I don't know what function is called in the OpenBSC when the user send the response in the mobile phone. Do you guys know the entry point function in this case ? Best Regards

Sms via SMPP - Questions
by Ludovic Rateau 24 Sep '13

24 Sep '13

Hi all, I'm working on OsmoNITB software and i am very interested in SMPP features. I have read some posts about SMPP in OSMONITB and i have some question about how to make it works. I have compiled openbsc ( based on http://openbsc.osmocom.org/trac/wiki/network_from_scratch ) with libsmpp34. All is good. When i start my OSMONITB, my netstat show listening port 2775. But how to connect and send a SMS via SMPP? I tried a little PHP script on github : https://github.com/onlinecity/php-smpp But i couldn't connect : INVALID SERVER ID Error 0xf Do i need to put a USERNAME and PASSWORD ? When i looked the code : in accept-all mode, all username and password are corrects. My BTS is in accept-all mode but i couldn't connect. So I tried an another program in C. And same error. Have you fixed this problem ? Is it working for you ? Second, Is there a mechanism to pass SMS from OSMONITB to an another server via SMPP ? Thanks for your help. -- *Ludovic RATEAU* R&D Engineer BJT PARTNERS -- -- *Ludovic RATEAU *Mobile : +33 6 04 10 5000

how gprs is called in openbsc, where to find the libgtb?
by Dai H. Tran 23 Sep '13

23 Sep '13

Hello everyone, I just recently learn about openbsc, and still in the phase of compiling and try to run the osmo-nitb app. 1st problem The problem is one of my teammate said the osmo-nitb will also started/call the osmo-sgsn program, but after examine the code, I still don't know how the osmo-sgsn is called from osmp-nitb, may be I was wrong, anyone can help me with this, how can I activate osmo-sgsn from osmo-nitb, with extra arguments? 2nd problem Another question, when I try to compile osmo-sgsn, the gtp lib is missing, as define in the makefile: *if HAVE_LIBGTP* *bin_PROGRAMS = osmo-gbproxy osmo-sgsn* *else* *bin_PROGRAMS = osmo-gbproxy* *endif* I don't know where to get this lib, so I modified by adding osmo-sgsn to the *else clause* as-well to have osmo-sgsn compiled. I still can run osmo-sgsn, but it show error about the gtp socket, i think the configuration is not correct, but not because of missing gtp lib, should this be a problem? Best regards, Dai

Mixed TCH/F and TCH/H issues
by Alexander Chemeris 22 Sep '13

22 Sep '13

Hi Andreas, We were testing TCH/H yesterday and stumbled upon an issue when a call is made between TCH/F and TCH/H. - When the call is from TCH/F to TCH/H, it doesn't connect. - When the call is from TCH/H to TCH/F, it connects, but voice quality is bad - sounds like 50% packet loss. Logs and localhost Wireshark captures of calls in both directions are here: http://ipse.chemeris.ru/osmo-captures/dumps.tar.xz Do you see what's wrong with them? Our configuration was * Dual-TRX with 1 TCH/F and 14 TCH/H channels. We have to keep some TCH/F channels, since there are old phones which doesn't support TCH/H. * Codecs enabled were FR, AFS and AHS. * LCR was connected to the MNCC socket, but in the case of TCH/F->TCH/H call I didn't see it coming to LCR at all. -- Regards, Alexander Chemeris.

Hi Harald (sorry for the typo). I think that line 10 is a log of the USSD call I made. My configuration is: - Followed the tutorial. ( http://openbsc.osmocom.org/trac/wiki/network_from_scratch (using all configurations shown in the tutoria, except the network name, that I changed to DCG). - Using a Ettus USRP N210 - All libraries installed in my notebook, with Ubuntu 13.04 kernel 3.8.0-29-generic. - Starting osmo-nitb with the following command: osmo-nitb -c ~/.osmocom/open-bsc.cfg -l ~/.osmocom/hlr.sqlite3 -P -m -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM - I manually select the network in the Network Preferences. The phone is an old Motorola Z6. Hope it helps. If you need more information, just ask. If you need, I can use other configurations or command options.
