this works well mith many mobile devices. With Nokia devices,
however, I do not get a PDP context. Here is an osmo-sgsn trace of
Nokia E65:
This is very likely a problem related to TLLI state tracking and LLC
sequence numbers. We have seen this for probably something like one
year in OsmoSGSN and sadly nobody has had enough of a problem with it to
actually debug it completely, fix it and contribute back a fix :/
Our own development is very much oriented towards features and fixes
that are required/requested by our own customers, and none of them is
using OsmoSGSN outside of a lab context, i.e. where those bugs would
cause a major inconvenience.
I guess it would require something like one day of focussed work to get
those TLLI and LLC sequence number issues sorted out.
Regards,
Harald
