Nokia crash during init is fixed

historical

Dear Harald,

The only outstanding problem is that during SMS sending, the Nokia Site familiy does not seems to send the release confirm, after the SMS is sent, and it generates a T200 timeout.

This problem is very similar to the issue Andreas fixed (the same problem seems to happen with handovers too on Nokia Site):

http://cgit.osmocom.org/openbsc/commit/?id=7d8fa3418ff6c589eba10e562da8b96995e19f7a

Actually if the above patch is enabled (nokia_site no-local-rel-conf 1), this problem is also seems to be "resolved". According to the standard the release confirm must be sent, so this is clearly an erroneous behavior of the Nokia BTSes. Maybe they use some additional/different signalling an their Abis implementation to signal this, but as I dont have any Nokia BSCs lying around, I cannot verify this.

Besides this I have some outstanding patches for Nokia Site specific features, like the RSL timer for UltraSite, and the ability to configure hopping and hopping type. I managed to do RF and baseband hopping on MetroSite, and RF hopping on UltraSite units with it :-) Will try and send it to you soon.

I also needed to register a new user name on osmocom.org. Can you please grant me edit right on the wiki pages? The user name is csaba.sipos My old account does not seems to work since the restructure of the site. Thanks!

Regards,
Csaba

Also feel free to make sure all known issues are reported in the redmine
issue tracker.  I think for Nokia specific issues, you are one of the
few people I know that regularly use this part of OpenBSC.

Regards,
