[ADM] Please try to avoid merges in the git tree
by Harald Welte 11 Dec '10

11 Dec '10

Hi all, this is just a general request to everyone with git commit access on the OpenBSC / Osmocom repositories. I would appreciate to restrict the use of 'git merge' to the absolute minimum neccessarry, as it makes the commitlog and timeline much harder to understand. If you're working on some private branch on a particular feature, please rebase that private branch on current master before pushing the changes. Thanks! -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Successfully Implemented SMS capable MSC & VLR
by tejas oza 10 Dec '10

10 Dec '10

Hi Holger, If you remember we are the students from Uppsala University Sweden. I am glad to inform you that we have done with our project. We have successfully implemented SMS capable MSC and VLR in Erlang, integrated with Mobile Arts SMSC, HLR and OpenBSC. We are also planning to make our project Open source and will inform you as soon as we will finalize it. -- *Thanks & Regards Tejas Oza Masters in Computer Science, Department of Information Technology, Uppsala University, Sweden.*

Control Interface
by Harald Welte 10 Dec '10

10 Dec '10

Hi Daniel, i am occasionally browsing the commitlog of the daniel/controlif branch and am wondering what exactly is happening there. It seems much more to me that 'controlif' is about reimplementing a lot of the functionality that already exists in the VTY, which I think is bad. My original understanding of the idea of SNMP support was: 1) we mostly want to export counters that we already have, but in a consistent/machine-parseable way. This is read-only 2) we may want to have traps 3) we have some (few!) things like rf_lock which should be issued (written) by the external SNMP process. Has the focus changed since this last discussion? Can anyone explain why that is? Even if we suddenly have a need for a lot of write/modify type settings from the SNMP side, we should not have two ways how to modify a single parameter inside OpenBSC. In that case we may need some code that can sort-of automatically 'export' all controlif parameter to the VTY, and remove the current code that sets this parameter from the VTY. Any ideas?

Compiling OpenBSC to use an extern MSC
by Luca Bertoncello 09 Dec '10

09 Dec '10

Hi, list! I'd like to try to compile OpenBSC with the A-over-IP in order to connect it to a real MSC. I found this document: http://openbsc.osmocom.org/trac/wiki/OpenBSCWithSCCP But when I try to get the branch I get an error: $ git checkout -b on-waves/bsc-master origin/bsc-master git checkout: updating paths is incompatible with switching branches/forcing Did you intend to checkout 'origin/bsc-master' which can not be resolved as commit? Is now this project in another branch? Can someone say me, what I have to do to compile it? Thanks a lot! -- _______________________________________________________________________ Luca Bertoncello Entwicklung Mail: bertoncello(a)netzing.de NETZING Solutions AG Tel.: 0351/41381 - 23 Fröbelstr. 57, 01159 Dresden Fax: 0351/41381 - 12 _______________________________________________________________________ Impressum: NETZING Solutions AG - Fröbelstraße 57 - 01159 Dresden Sitz der Gesellschaft Amtsgericht Dresden HRB 18926 Vorstand Dieter Schneider - Aufsichtsratsvorsitzender Volker Kanitz USt.Id DE211326547 Mail: netzing.ag(a)netzing.de

Moving subscr_{get/put}_channel in gsm_subscr.c (instead of gsm_subscr_base.c)
by Sylvain Munaut 09 Dec '10

09 Dec '10

Hi, I'm now having another look at implementing MT ciphering. For this, I need to work inside the paging system. What I'd like is that the MSC part instead of ever using paging_request directly, that they all use subscr_get_channel. Then this would also encapsulate securing the channel and only call the call back when the channel has been ciphered and is ready for the MSC part. This requires making some gsm_04_08 call inside the subscr_get_channel, so I need to move that call to the 'msc' side of gsm_subscr.c To me, it makes sense. I don't see in what context a BSC would use get/put channel ... the BSC doesn't decide, it's just ordered what to do by the MSC IIUC. I would then also replace all calls to paging_request in gsm_04_08.c by calls to subscr_get_channel. And also move the "paging_succeded" signal dispatch to the subscr_get_channel call back and not directly from gsm_04_08_utils.c (since that signal is used currently to trigger SMS delivery and other "side" things when we have a channel, it's more a MSC thing). Finally, I'd need to pass the msgb paging response all the way to the paging callback because it contains important field to enable ciphering. Any objections to this plan ? Did I miss something ? Cheers, Sylvain

multi-drop-configuration
by Thomas Ansorg 09 Dec '10

09 Dec '10

hello the cables are built, now i want to use 2 bs11 in multi drop config. how do i connect the 2 bs11? the e1 comes from the pc to the 1st bs11 left half, left tx, right rx(front view). now i'm on the right half: to which port are the 2 bnc port from the 1st to the 2nd bs11 to be connected? i tried the 2 possible combinations, didn't work (with the openbsc.cfg.2-2). the 2 bs11 are both set to tei=25 (bs11_config told me so) a schematic would be perfect. second problem: the timer instructions in the openbsc.cfg.2-2 are not executable, the bsc_hack program stops there. i had to remove them. what's the matter with that, why don't these timer instructions work? answers in german *very* welcome! -- Wer Rechtschreibfehler findet, darf sie behalten!

socket problem
by jason mercury 07 Dec '10

07 Dec '10

Hi to all, In order to execute two bsc_hack at the same time i have changed port for oml link from nv_put_oml() function in ipaccess_config.c and i also changed oml port from ipaccess.h . When i configure nanoBTS with ipaccess_config i can establish two different oml link between two bsc_hack and two nanoBTS. rslHowever, they can not establish link at the same time. I could not find where can i change rsl port of nanoBTS. I have searched the wiki and i could not find a nanoBTS message to change the port specified for rsl link. Could anyone give me some information about this? Thanks. Jason

OpenBSC and Asterisk with NanoBTS and no ISDN
by Chris Rankine 07 Dec '10

07 Dec '10

I am trying to get OpenBSC working with Asterisk for a class project. I have a NanoBTS DCS1800. I was hoping to get this to work entirely over Ethernet, as the server is running on a controlled VM cluster with no way of getting an add-on ISDN card in. I have attempted to follow the OpenBSC+LCR+Asterisks route. But as expected, LCR gives me issues when it does not find an ISDN card. I am not familiar with LCR to tweak it. Can I use LCR without an ISDN card? What should I look into to get this done? I have also attempted to modify the asterisk chan_openbsc code to comply with the libosmo break off earlier this year. With a few Makefile adjustments, include a few more header files, and strip out some debuging code, everything will compile. However, asterisk seg faults when the module loads. The gdb output is: Program received signal SIGSEGV, Segmentation fault. 0xb72fcd1d in cmd_execute_command_strict (vline=0x83d4c88, vty=0x83c2450, cmd=0x0) at command.c:2000 2000 cmd_vector = vector_copy(cmd_node_vector(cmdvec, vty->node)); I am not familar with this code, so all I can do is comment out things in an attempt to debug. Eventually I keep it from crashing, and the nanoBTS will make contact with the driver. However, since the code that gets commented out also involves loading the cfg, the BTS does not get bootstraped. This is all running on Gentoo, though I have also tried on Debian and Ubunto. Any help would be appreciated.
