Storing Wi-Fi and cellular tower database to assist cellular network system selection

Abstract:

A method of selecting a cellular network includes storing a location database in a memory of a mobile device, the location database providing location data for one or more locations each identified by a unique identifier, in response to recognizing the identifier, determining a current location of the mobile device by looking up the identifier in the database, prioritizing bands based on the current location to define a band priority, and selecting the cellular network based on the band priority.
