I means: is the interaction with mtp3 layer implemented (is sending sccp data by mtp3 implemented by the library?)? Also, what about the reception of data from mtp3 layer. is that implemented in the sccp lib. I am asking these questions because I see the code of mtp3 in the lib but no significant call is present in the sccp part of the lib. Thank you for your help.

Several questions

by jason mercury

I have some questions: 1) When I start bsc_hack bsc_init.c first establishes OML link and initializes the bts then it establishes RSL link and bts starts broadcasting. However, it takes so much time to start the bts. Instead of this I want to do the following: it establishes OML link at the beginning and only once, then when i want to start broadcasting it establishes just the RSL link and bts will start faster since i don't have to wait for OML link. What should be done for this? 2) If i send one or two word messages from telnet interface it is okay. But if i send a longer message the phone could't receive the end of the message correctly(last words may be incomplete). Did any one encounter with this problem? What is wrong with me? 3) Could I send SMS in which extension of the sender is text not integer. For example, i want to send an information SMS that this is a test network. For this purpose i want to send an SMS from 'OpenBSC'. I set the extension of the first subscriber in database as text and tried to send the SMS but SMS wasn't delivered. What should i do? 4) Can i add SMS externally to SMS table of database? Thanks. Jason

spec download

by Joe Eggleston

Hi all, Maybe I'm missing something, but I haven't found an easy way to download pdf versions of all the 3gpp specs. Why would you want to do that? Well, dealing with MS-Word format is a pain. And, there's no online full-text search of all the specs. So, I threw together a quick web scraper to pull down the latest version of all the 3GPP specs from the ETSI web site in pdf format. Thought it might be useful to others - http://monkey.org/~joe/files/fetch_3gpp.py Feel free to contact me if you have any trouble using it. -Joe

Timing Advance

by Nordin

Hello guys, I haven't been busy with openbsc for a while, however, I was following the mailing-list. I have the following question, is timing advance also implemented for the nanoBTS? Cause I don't really know where to look in the sources, thank you.

Re: How to download firmware and configure NanoBTS the first time...

by Ravi Shankar

Nothing required actually. The firmware is preloaded.Just configure the Nanobts using the installation CD given.

AW: fix of chan_lcr / new socket interface for openbsc

by Andreas.Eversberg

hi harald, i would also suggest to combine mncc.h of openbsc and osmocom-bb first, and move it to libosmocore. this way the LCR (or other mncc_socket client) does not depend on any files of openbsc and osmocom-bb, just on libosmocore. because i like to use the same socket interface for osmocom-bb, i would suggest to to put mncc_sock.c into libosmocore too, so it must not be implemented twice. then i would make lcr to be able to connect to both osmocom-bb and openbsc sockets. finally there is no more polling of file descriptor required at lcr. if you agree, can you move the code to libosmocore? i will work on the socket configuration and see what i can do with the versioning. andreas -----Ursprüngliche Nachricht----- Von: Harald Welte [mailto:laforge@gnumonks.org] Gesendet: Dienstag, 22. Februar 2011 13:22 An: Andreas.Eversberg Cc: openbsc(a)lists.gnumonks.org Betreff: Re: fix of chan_lcr / new socket interface for openbsc Andreas, thanks for integrating the mncc socket patch into lcr. I would personally like to see the following improvements: * add some (preferrable automatically computed) version to the mncc, to make sure you cannot run lcr + bsc_hack built from a different mncc.h file. We could do something like a md5sum over the header at compilation time, stored in both openbsc and lcr. Once they connect the mncc socket, they request the remote side md5-value and compare it with the local-side value. If they don't match, print an error message and exit the program. * make the socket path configurable, which is required for running multiple instances of openbsc+lcr on the same machine. If you (or anyone else on this list) happens to have some time to work on that, it would be greatly appreciated. Regards, Harald

fix of chan_lcr / new socket interface for openbsc

by Andreas.Eversberg

hi, the broken chan_lcr is now fixed in the "develop" branch of lcr git. i have tested it with asterisk 1.8.1. the locking seems to be improved in this asterisk version. i could not run it in a deadlock, as i could with asterisk 1.6. i would suggest to try this out, but please keep your current asterisk and lcr sources. if all works fine, i would like to merge the "develop" branch into the "master" branch soon. for the gsm users: the second change in the "develop" branch is the socket interface between openbsc and lcr. thanks to harald welte for providing this patch. instead of linking openbsc to lcr, openbsc runs it's own process. (using bsc_hack as usual) lcr connects to a socket of openbsc. with it, the gsm.conf became obsolte and has been removed from lcr. in order to run lcr with openbsc ("master" branch of openbsc) : bsc_hack -P -m -l <sqlite-database> -c <openbsc-config> -P is required to enable rtp proxy for use with ipaccess bts. -m is required to allow call control via socket interface to get lcr from "develop" branch, do: git-clone git://git.misdn.org/git/lcr.git/ cd lcr sh checkout-branch.sh develop regards, andreas

New utility for drawing protocol ladder diagrams

by Harald Welte

Hi! With the help of graphviz, I have written a small perl-based tool that allows you to generate ladder diagrams. It can be found at git://git.osmocom.org/gen_ladder.git For your reference, I'm attaching a sample input and output file. The bent/curved arrows are a result of graphviz trying to indicate that the message is between e.g. MS and MSC and 'bypasses' BTS and BSC. I'm still waiting for somebody with more graphviz skills to make this an option. Hope this is useful for some of you... -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
