Hi all,
I have set up the EGPRS network using software bundles (osmo-nitb + osmo-bts-trx + osmo-trx + osmo-pcu + osmo-sgsn + openggsn) based on the USRP B210 platform. Now the cell phone can connect to the EGPRS network, but the network is not stable and the data rate is too low (only about 8kbs).
Is this data rate correct? If not, could you pls send me some working config files? Thank you.
Best Regards,
Xinke
For quite some time, osmo-pcu has been causing build failures on Debian 8.
You can find a build log e.g. at https://build.opensuse.org/package/live_build_log/network:osmocom:nightly/o…
The visible sign is that for some reasson there are additional log lines present
in the output of our unit tests, like:
[ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) downlink acknowledge
[ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) Final ACK received.
[ 127s] +DL packet loss of IMSI= / TLLI=0xffeeddcc: 0%
[ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=FLOW EGPRS) changes state from FLOW to WAIT RELEASE
[ 127s] TBF(TFI=0 TLLI=0xffeeddcc DIR=DL STATE=WAIT RELEASE EGPRS) starting timer T3193 [release (DL-TBF)] with 0 sec. 0 microsec, cur_fn=0
where the "+" is the unexpected additional line.
Does anyone have any information about why that is? I don't see any related changes
recently.
