Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0036] This application provides a scheme for updating map data, and the scheme involves a server and a client. The server stores map data, and whenever new map data is imported into the server, the server will receive a map data change notification. The client may be a user device that supports third-party application software, such as a mobile phone, a tablet computer, or a notebook computer.

Abstract

The present application discloses a method and device for updating map data. The method includes: when receiving a map data change notification, determining the geographical area to which the changed map data belongs; The target client; determine the scope of the target geographical area to which the map data to be changed by the target client belongs; send an update message to the target client, and the update message includes the target to which the map data to be changed by the target client belongs geographic area range. In this application, when the server receives the map data update notification, it actively sends an update message to the target client that needs to update the map data, so that the target client can delete the outdated map data, making the update of the map data more timely, and, according to The solution of this application does not require the client to request the server frequently, which reduces the request pressure on the server.

Description

technical field [0001] The present application relates to the technical field of data update, and more specifically, to a method, device and system for updating map data. Background technique [0002] With the construction and changes of the road network, the map data corresponding to the road network is also constantly updated. In order to ensure that the map application client provides accurate route services for users, it is necessary to update the map data of the client in time. [0003] Currently, the way the client updates the map data is that the client actively requests the latest version number of the map data from the server according to a fixed detection cycle, and then compares the version number of the local map data with the version number issued by the server. If the version number of the local map data is smaller than the version number issued by the server, it is determined that the local map data is outdated, and then the local map data is deleted. Later,...
