Re: [PATCH 1/2] libosmocore: remove GSM-specific functions (they now belong to libosmo-gsm)
by Sylvain Munaut 18 Mar '11

Hi, > I forgot to say that VTY code still remains in libosmocore, I'll study > if it can be interesting in a new library (I can do this later, once > this patches are applied, of course). gsmtap is a misnomer, but we now use it for TETRA as well ... crc16 possibly common as well (altough not sure). In general, if we have functions that are common to several protocols but are not really 'system' stuff like select/timer or stuff like that, where should we put them ? Keep them in libosmocore ? (like a include/osmocom/utils or also in 'core' ?) Also, for future enhancement (future patches, just mentioning it here since it's kinda related to the whole library cleanup), Harald mentionned to replace the include/osmocore by include/osmocom/core (like it was done for vty / code / ...) Cheers, Sylvain

[PATCH] osmocom-bb: build: use new libosmo-gsm library
by Pablo Neira Ayuso 18 Mar '11

18 Mar '11

This patch requires the appropriate git-subtree magic to include the new proposed libosmo-gsm into osmocom-bb (as it happens with libosmocore).

With a nanoBTS, you don't need a real ISDN card. You can use mISDN modules which are typically compiled in as modules in Linux. My lab has a few 900 and 1800 nanoBTS units, all running over Ethernet/IP, with openBSC, Asterisk, and LCR running on VMs with no ISDN cards, no special hardware. There is a tutorial on how to set this up here, http://openbsc.osmocom.org/trac/wiki/OpenBSC_LCR . I also found a mailing list post that fills in some blanks, http://www.mail-archive.com/openbsc@lists.gnumonks.org/msg00352.html . I would suggest trying to follow the mailing list post to the letter to set this up, and once it is working make a snapshot then try to update the source of the packages installed.

Connecting more OpenBSC together
by Luca Bertoncello 17 Mar '11

17 Mar '11

Hi, list! I have more OpenBSC running on different IPs and using different configurations, and I need to connect them together, so that it is possible to have, for example, two mobile phones connected to two different OpenBSCs and able to make calls with each other. Is it possible? Can you suggest me an HowTo?

oml and RSL - 2nd try
by Thomas Ansorg 17 Mar '11

17 Mar '11

hello ok, lets try it again: do the oml and rsl settings have to be identical? for example: one bts is set to port 0, ts 1, tei 25. the cfg entry would be "oml e1 line 0 timeslot 1 sub-slot full" and "rsl e1 line 0 timeslot 1 sub-slot full", right? the cited link is useless, i kno it already, doesnt answer my question. what i wanted to know is why we have 2 types of settings (oml and rsl) which are identical, cause that told the openbsc.cfg. why do we need 2 settings that configure the same? or was the assumption above wrong?

[Patch] Using MySQL as database for OpenBSC
by Luca Bertoncello 15 Mar '11

15 Mar '11

Hi, list! I need to use MySQL as database for OpenBSC due to the limitations of SQLite (I need concurrent access to the database). I wrote a little patch to allow it and I send it as attachment. With this patch the database is **ONLY** MySQL. Maybe in the future, if I'll have time, I'll write another patch to allow the user to choose the preferred database (SQLite3 or MySQL).
