I have used SMSlib for a similar purpose. It is an open source Java library for sending and receiving SMS with a wireless modem. I used it as a framework to communicate with the modem and extract its signal quality measurements.
The basic algorithm is:
-- Force the modem into 3G mode (that's what I'm interested in)
-- Loop every minute:
-- Read and record RSSI, BER, SNR
You can read about the details on:

There are also my measurements at two locations: "good" and "bad".
With a bit more work this approach can be extended to correlate RF parameters with some other (IP) measurements you mention. It can also be extended to make it a mobile measurement that you require.
I am currently working on a more accurate interpretation of some of the RF measurements.
Best regards, Novak.
