Holger Hans Peter Freyther holger at freyther.deHi, as indicated in the previous mail there are some things to be done before we get to the venue. I would like to experiment with sprints to solve some of the stability issues we had with osmo-nitb. The idea is that we assemble (physically or online) and work on some specific issues of osmo-nitb that impact the quality of service for the upcoming event. I can provide food and snacks during these sprints and guidance on OpenBSC code. The first sprint is scheduled for the 9th, 10th (and maybe 11th) of November. There is no venue for it yet, maybe the CCCB. Please indicate if you are interested to join. The general list of osmo-nitb issues are: * Channel release process. There is a branch I created at the last congress but I have never tested it. This includes making a SAPI=3 local release, using the proper timeouts for the abnormal release making sure the SACCH is deactivated and some more issues. This requires quite a bit of testing. * Allow to block/unblock failing lchans. We have had this issue with Nokia BTS but it can happen on other BTS as well. E.g. a given timeslot might not be allocatable, or we get LCHAN ACT NACK. In that case OpenBSC should block the lchan. * smsqueue/auth/paths. In the past years we have seen that the smsqueue and other parts can get stuck because of the 'subscr_get_con' not being properly called in all error conditions. We need to review the code and check how things get stuck. * Handover testing and patching out the 'timestamp' adjusting or fixing it. Right now it can be used to add a lot of delay by switching cells. cheers holger
