[RFT] Couple of changes to nanoBTS and nokia insites bootup sequences to be tested
by Sylvain Munaut 20 Oct '11

20 Oct '11

Hi, I've just pushed a couples of changes to a branch sylvain/pending that need to be tested. They alter the startup process for the nanoBTS (fixing the issues some people had with starting GPRS support, when the bts was not connecting to the SGSN). And also a fix for the Nokia InSite startup sequence where the reset command was not sent due to missing initialization of .do_reset. Since I know initialization sequence can be a rather fragile process, if people could test this didn't break anything for them, it'd be nice. Cheers, Sylvain

Hi, > That’s all I get, and it never bootstraps. In libosmo-abis, in src/input/lapd.c line 90, try replacing 0,240000, by 0,480000, Also, make sure you plugged the power like 10 min before trying. Cheers, Sylvain

A configuration option is fine, I would set the default to "always reset" and only if someone know what he does, he can turn the reset off (I think I had strange effects while changing the configuration and not doing a reset, so this situation should be avoided).

Legal situation when using auth policy token
by Lennart Müller 19 Oct '11

19 Oct '11

Hi, we own a frequency usage licence from the Bundesnetzagentur and ran our network with auth policy token. So every new phone trying to attach to our network will receive a SMS with information how to register and a token. Thereafter, the phone is kicked out and will no longer be able to register again. Now there was a problem with some phones from Cupertino which, as I heard, registered to our network, received the SMS, were kicked out again but did not try to re-register with their home network. So some "nice" guys threaten to call the Bundesnetzagentur if we will not shut down the network immediately. As a quick solution, we changed the registration procedure from Token-Input to IMEI-Input. My question is: Are there really legal problems when using the "Auth Token" policy? Many Thanks, Lennart

[RFC] libosmocore: New libosmosdr sub library
by Sylvain Munaut 19 Oct '11

19 Oct '11

Hi, I've just pushed a libosmosdr sublibrary in a sylvain/sdr branch in the libosmocore git. Currently it contains mostly a complex vector 'class' along with various math functions used on them (convolution / correlation / ...). Some aspects the the API along with some of the underlying math are inspired by the code from openbts, but it is a complete rewrite in pure C with some aspects simplified, and some others extended. If anybody has comments before I merge it in master, they're welcome. The doxygen doc should be clear enough (and even includes fancy latex equation :P) Cheers, Sylvain

[PATCH 0/3] rb-tree based timer infrastructure for libosmocore
by pablo＠gnumonks.org 18 Oct '11

18 Oct '11

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> Hi! This patch reworks the timer insfrastructure of libosmocore to make it more scalable. I remember some discussion with Harald while I was in Berlin that this can be of interest. It also reworks the timer torture test, the current list-based timer seems to have problem with it. You can find this changes in the pablo/timer branch.

The Reset command was enabled in my initial version. As far as I know it was intentionally disabled during the CCC camp to get faster turnaround times while setting up the camp network. Its possible to skip the reset if nothing has changed in the configuration, however if for example the ARFCN is changed, the reset is required (it might be possible to do a TRX-only reset but I never tested it).
