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

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

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

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

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

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.

Re: OpenBSC + USSD Application

by Maicon Kist

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.
