Description

I am told this only happens when at a long distance from the tower. - In the case of this actual recording, the MS was at more or less the "edge" of the usable cell in terms of RF. DL/UL Level around -100 dB

It was only on the downlink.

would of course be quite interesting to see the related logs / pcaps at the time this is happening.

Thanks Harald, and of course! But Commit Early, Commit often is how the saying goes right?

At this time this happened, this was all I got. Feedback about having noted this issue and this recording.
Posted here to open the issue and in the vague hope that maybe somebody might recognize it. An "Ah I heard that once and it was due to..... " of course would also be of help.

:-) Once osmo-time-machine is updated, I'll go back and get the pcaps. For now we'll have to wait until next time somebody I can coordinate with is on site, observes this again and we can try to reproduce and log. :)

Yes, I guess I should be logging everything. Which I was doing, but level all debug filled the HDD in less than a day. I need to figure out exactly what is best to log from each daemon.

I am assuming this was related to bad TA, that was fixed in https://gerrit.osmocom.org/c/osmo-bsc/+/25607
