Navigation method, terminal and system

Abstract

The invention provides a navigation method, terminal and system. The navigation method comprises the following steps of: pre-storing one or more map modules in a local map; acquiring a starting address and a destination address; and judging whether the local map can provide a navigation route from the starting address to the destination address, if so, starting local navigation, or starting network navigation. By virtue of the navigation method, terminal and system provided by the invention, the local navigation or the network navigation can be selected according to practical application when a navigation service is provided for a client, thereby the local map is fully utilized, the network downloading flow is reduced, and the user cost is saved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a navigation method, a navigation terminal and a navigation system. Background technique [0002] With the continuous expansion of the city scale, the range of activities is also continuously expanded, and the application of navigation equipment is also becoming more and more extensive. Existing navigation methods mainly include local navigation and network navigation. [0003] Local navigation refers to downloading all map data (such as national or global map data) to the local map of the navigation terminal at one time. The navigation terminal completely relies on the local map data to query the start point and end point. Through the routing algorithm Calculate the navigation route, combine with the global positioning system (GPS) to obtain the current position, and realize the navigation function. [0004] The local navigation method has the following dis...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the need to download and install all map data into the local map, very expensive authorization fees are required

Moreover, in actual use, users often only use the map data of a few cities, so the user cost is very high

[0006] 2. Since the map data is changing rapidly with the development of the city, but because the map data is pre-downloaded and installed in the navigation device in the local navigation method, it is difficult for the map data to be effectively updated in real time, so it is also difficult to Provide real-time navigation information for users

[0009] 1. Since the network navigation needs to rely on the network navigation server to complete the navigation, the navigation function cannot be realized without a network signal

[0010] 2. When the network signal is relatively poor, the starting point and end point can be found, and navigation can be initiated. However, when the user quickly switches routes, due to the poor network signal, the navigation route is difficult to update in time, thereby reducing the user experience of navigation

[0011] 3. Since a network connection is required for each navigation, and the navigation information must be continuously received from the network navigation server during the navigation process, the generated network traffic is very large, and the user cost is relatively high
