Date: Fri, 27 May 2016 18:02:28 +0200 From: Pierre Baudry pierre.baudry@diateam.net I noticed that since several weeks that osmo-pcu did not work as good as previously.
Yes we have also seen similar failures for GPRS calls in the osmo-pcu. Our setup uses NuRAN hardware with osmo-bts-sysmo
The latest "good" revision I am aware of is commit d87e1d6ab747423d3668c74d16201a5d967accf0 (2015/12/14)
This is a useful information for us that the above mentioned commit works for GPRS.
Can somebody confirm or reproduce this attitude ?
The PCU log that we have during failure matches with the one you have reported. We have tried a workaround for this GPRS call failure by forcing two-phase-access in osmo-pcu.cfg. Based on our analysis done till now it seems One phase access of GPRS is broken.
I will try to provide more logs and a pcap capture as soon as I get hands back on the hardware.
It will be quite useful to narrow down the issue, so please share the relevant logs collected
