Problems solved by technology

[0005] However, as the fineness of the map increases and the amount of data increases, the aforementioned embedded navigation system needs a large amount of memory or data storage media to provide users with map data in different regions, which increases the manufacturing cost, or cause inconvenience to users
[0006] In addition, the aforementioned separated navigation system also needs a large amount of memory to store the downloaded map data, and when the connection speed between the navigation system and the map server is insufficient, it is easy to cause the update of the map data to be insufficient and affect the navigation function.

Abstract

The present invention provides a method for downloading map, suitable for mobile device connected to a map server. The method mainly comprises that: determining the current position of the mobile device, then determining the predetermined distance, determining the first map data and the second map data according to the predetermined distance. Specially, the first map data is corresponded totally with map data of current position in predetermined distance, the second map data is corresponded with map data of current position out of predetermined distance. Finally, the mobile device downloads map data from map server, the map data at least includes the first map data. Through the method of the invention, users can download map selectively according to demand and surroundings. The mobile device and method can reduce the use of memory, and manufacturing cost, and enables the users to operate the mobile device swimmingly.

Description

technical field [0001] The present invention relates to a mobile apparatus (Mobile apparatus) and method for downloading maps. Background technique [0002] Nowadays, it is used in mobile devices, such as mobile phones, personal digital assistants (PDAs), etc., which can have a built-in Global Positioning System (GPS) subsystem, or combine with accessories containing a GPS subsystem through a two-way connection, thereby providing users with Map download and navigation functions. For example, US Patent No. 5,786,789 discloses a GPS and mobile phone unit with add-on modules. [0003] In particular, when the user is driving a vehicle, such navigation functions can provide icon information such as destination location, route, environment, etc., to help the user reach the destination faster. [0004] In addition, the navigation system (Navigation system) used on vehicles can be mainly divided into two categories: embedded (On-board) navigation system, this type of navigation sy...
