Map updating method and device

Abstract

The embodiment of the invention provides a map updating method and a map updating device. The map updating method comprises the following steps that: terminal equipment records path information by using a navigation module; the terminal equipment transmits the path information to a map updating server so that the map updating server updates a map database in the map updating server by adopting the path information; the terminal equipment receives a map updating informing message which is transmitted by the map updating server, wherein the map updating informing message comprises the information about updating the path information; the terminal equipment updates a map database in the terminal equipment by adopting the path information in the map updating informing message. The map updating method and the map updating device provided by the embodiment of the invention are used for shortening the updating period of a navigation map; the navigation precision of a user by using the terminal equipment is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for updating a map. Background technique [0002] With the development of navigation technology, civilian navigation technology has been widely used in various mobile terminal devices. In addition to a dedicated vehicle navigator, various smart phones, tablet computers and other portable terminal devices are also integrated with a Global Positioning System (Global Positioning System, GPS) module or other navigation modules. [0003] A terminal device having a navigation module may be called a navigation terminal, and the function of the navigation terminal is to provide users with services such as positioning and navigation. When the navigation terminal implements functions such as positioning and navigation, in addition to the navigation module, it also needs the cooperation of a map. The map in the navigation terminal is called a navigation map. The...

However, the actual road conditions may change at any time due to reasons such as municipal planning, maintenance, reconstruction and expansion, and authoritative organizations generally release updated maps after a long period of time. Using maps issued by authoritative organizations to update navigation maps will cause navigation The map does not match the actual road conditions for a long time; on-the-spot measurement is time-consuming, labor-intensive, costly, and the real-time performance is not strong, so it is not suitable for large-scale

Therefore, when a user uses a navigation terminal to navigate at present, the situation that the navigation map is inconsistent with the actual road conditions often occurs, which affects the user's use.
