Patent number: 11187541Abstract: A method of requesting map data by a wireless communications device entails steps of predicting a future area of interest for which map data may be required, downloading the map data for the future area of interest, and then caching the map data for the future area of interest. Cached map data is thus available for rendering when the device moves into the future area of interest, thus expediting the generation of onscreen maps. Predicting the future area of interest can be accomplished, for example, by determining the direction of travel, by identifying a roadway upon which the device user is travelling, or by identifying a programmed route in a navigation application.Type: GrantFiled: January 15, 2009Date of Patent: November 30, 2021Assignee: BlackBerry LimitedInventors: Christophe Gibran, Robert Watt, Michael J.
