Thanks. Time is limited but will try..

I know nothing of cell tech - can one only get mast info from a network on which you are registered? What info do other provider's transmitters send?
You could get info of all available networks around but this will cost in battery. Here, the idea is to use the one that the device is already connected/uses. This is a function it already needs to do so that it is reachable in the GSM network for the phone function and the device weaks up when necessary.

The extra 'cost' is to get notified and log this change everytime it happens. Using DBus (which is designed/optimised for efficiency) already minimises the impact of the first part of the action needed.

Cheers
