Problems solved by technology
Due to the time delay of network transmission, network congestion and the calculation of the best path consumes a lot of computer time, the newly calculated best path cannot be sent back to the navigation terminal in time, making it difficult for the existing navigation methods to be practically applied to network navigation. , and, in order to calculate the optimal path, a large number of servers need to be deployed, which will also increase the application cost

The invention discloses navigation terminal and method. Different from a linear optimal path provided by the traditional navigation method, the navigation terminal and method which are provided by the embodiment of the invention can realize the navigation by only acquiring navigation data related to a destination without calculating an optimal path and can be applicable for network navigation. Inaddition, the acquired navigation data are facet data, i.e. the navigation data comprises roads leading to the destination from various directions, thereby a user of the navigation terminal can be ensured to select the driving according to the current road condition, the defects that a single optimal path result is only given in the traditional navigation technology and an emergency prompt cannotbe provided in time under the unexpected traffic condition are avoided and more flexible navigation is provided for the user of the navigation terminal.
Description
[0001] This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on August 7, 2009 with the application number 200910091106.6 and the invention title "Navigation Terminal and Navigation Method", the entire content of which is incorporated into this application by reference. Technical field [0002] The present invention relates to a navigation terminal and a navigation method, and in particular to a navigation terminal and a navigation terminal that can navigate to the destination based on navigation data around the destination, key areas or key points on the way to the destination without calculating the optimal path Navigation method. Background technique [0003] The existing navigation technology is a navigation technology based on satellite positioning. It combines a satellite positioning system with a mobile terminal. It can not only provide users with positioning information such as longitude and latitude, but also provide user...
