Hi Jacob,
Thanks for the info, will try that.
What algorithm (PCU) would you prefer if the goal is to maximize the single UE
throughput?
Regards,
Csaba

I finally have a more or less working setup. At least there is no crash whatsoever, and
the PS domain is working, the UE can attach, activate PDP, transfer data to some extent.
For example when i tried to ping the TUN interface, I got 2500-2600ms latency.
That's normal in the default case, since the MS will have to issue a
RACH to get an uplink TBF for the response. You can allow to keep the
PACCH open for a longer time by configuring
pcu
dl-tbf-idle-time 2000
This keeps the DL TBF open for the time given (in ms) by periodically
sending LLC dummy commands.
