Serving cell frequency is, or should be, included in the nmr list in the
arfcn variable. I believe the arfcn, bsic and rxlev are needed for all
cells since this information is used for location determination.

As far as I know, the neighbor cell info in the above-mentioned form is
used for location specific purposes. Hence, bsic suffices to identify
base station and rxlev gives the unscaled distance from it.
If there is a reason for including LAC and CI for neighboring cells, we
can add them to the list. In that case we should probably modify the
DBUS method list to include one method for requesting location data and
another method for general identity data.
Best Regards,
Antti
