Method of scanning wireless frequencies

摘要

A method of scanning frequencies for registration onto a wireless service provider by a wireless device is provided. The inventive method comprises predefining priority sequences of frequencies each in association with each of a plurality of locations and storing the priority sequences on the wireless device. Itinerary information is received and stored on the wireless device. A current expected location of the wireless device is determined in real-time on the wireless device based on the itinerary information. The priority sequence to be scanned based on the current expected location is then determined on the wireless device and frequencies scanned according to the determined priority sequence.
