I don't know of any strategy that uses GPS location to decide when to switch between towers. A tower could be offline for maintenance. You're probably going to want to use the signal strength from the tower as the strongest indicator of switching. Aside from that ENodeB uses GPS for timing. At the base station. In a way that does not require your phone to _also_ have GPS.
