All cell-id based positioning is done server side (unless you have the whole
database in your device) Do you have any indication that Google is using
rxlevels and timing advance? Are there any devices that supports access to
these measures? To do any kind of combination you still need to extract all
of the data from the device and send to the server. Google doesn't have
access to any kind of data from the network. 

Would be interesting with some more information around this if you have.
