Abstract
Systems and methods for compiling lists of prospective access points for offloading cellular data traffic for a vehicle, and for selecting an access point to establish a non-cellular wireless Internet connection. Vehicular data mobile access involves properties and characteristics different from those of portable user data devices, and thus exhibit different criteria for cellular data offloading. Embodiments of the invention provide vehicle metrics to be used in conjunction with data requirement metrics in compiling the access lists and making the optimum selections based on the vehicle's predicted route. A predictive look-ahead is also provided, for use when predictive routing information is not available or is unreliable.
