openbsc build was broken due to change in libosmocore: missing doc for 'log gsmtap [HOSTNAME]'
by Neels Hofmeyr 11 Dec '16

11 Dec '16

The libosmocore commit aa00f99be2e4cc64ede20d8c9548b83054696581 adds a VTY item that's missing a doc string, hence breaking the openbsc build (which actually checks the doc strings unlike the libosmocore build job). I pushed the fix I734b22c950242541322e902887bf779c14ba10fd and things should light up "green" (aka blue) again. BTW, in a RL discussion lynxis suggested that it would be good if libosmocore commits were also checked against breaking openbsc. A point against it is that often something in libosmocore is changed and requires a follow-up in openbsc -- if the libosmocore build rejects commits that break openbsc, it would make it impossible to get these changes in. The workaround could be to have a secondary build job that merely comments on gerrit whether the openbsc build still works, without having -V voting powers. Anyway, so far I think it is sufficient to catch these hopefully few cases once the regular master build on jenkins.osmocore.org goes up red, like now. ~N -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

So on A this looks right. The LAI is 262-79-1 and this is where you are paging. In general it might be: * osmo-bsc doesn't translate this to actual paging. E.g. not linking/ handling the location area identifier. You could trace the RSL protocol and see if a paging command is being sent (periodically) to the BTS? * The MS still has a radio channel open. I notice that clear command is being sent so this is unlikely to be the case. Also IMSI seems to be match.. maybe the MS still calculates the paging group wrongly?

range1024 encoding question
by Max 08 Dec '16

08 Dec '16

Hi. I've stumbled upon situation where range1024 encoding produces weird results - see gerrit #1373 and http://jenkins.osmocom.org/jenkins/job/OpenBSC-gerrit/1515/IU=--disable-iu,… right before "Wrong number of arfcns" Is this because I call it somehow wrong or there's actually a flaw in our implementation? -- Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte

M2M call with no voice
by Kristian Martens 08 Dec '16

08 Dec '16

Hello, I got a mobile to mobile call working for signalling only. Two RTP channels are being established successfully. But there are only a few pattern sent over these channels (1 byte 0x23 as UDP payload). Is there a setting I am missing in the configuration files? Please find attached a .zip file with pcap and cfg files. Thanks, Kristian

MGCP logging
by Kristian Martens 07 Dec '16

07 Dec '16

Dear all, I have switched on logging to file and have set the log level to "debug" for "mgcp" in both osmo-bsc.cfg and osmo-bsc-mgcp.cfg. Still I cannot find any output in the log file related to MGCP if I get an error. Is there a trick to make the MGCP module more verbose? Thanks, Kristian

osmo-trx debian nightly builds fail due to uhd requirement
by Harald Welte 06 Dec '16

06 Dec '16

Dear all, as osmo-trx has recently introduced a dependency on a super-recent version of UHD (as opposed to what regular stable distributions ship), the nightly debian builds are broken for both Debian 8.0 and Ubuntu 14.04: https://build.opensuse.org/package/show/network:osmocom:nightly/osmo-trx I would like to ask the osmo-trx folks to consider a) adding the uhd version dependencly to the debian rules b) submitting a suitable uhd package version that can be build in the osmoco nightly OBS repository Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
