Communication method and system for sharing navigation information

Abstract

The present invention is applicable to the technical field of navigation and communication, and provides a communication method and system for sharing navigation information. The method includes: the server establishes a temporary friend group according to the group request sent by the navigation terminal; the server receives the temporary friend group of the navigation terminal A navigation terminal user in the group sends a navigation route information sharing request, and sends the navigation route information to other navigation terminal users in the temporary friend group; all navigation terminal users in the temporary friend group are displayed on the navigation terminals The navigation route information is the same, and the navigation terminal performs navigation according to the navigation route information; the server deletes the temporary group friend user group after the navigation is completed. The invention can realize the navigation synchronization function of multiple navigation terminals. When traveling, any friend can pull other friends to form a temporary group tour group, and the position information of all members in the group can be displayed synchronously on the navigation map of the navigation terminal. Group intercom can be used between navigation terminals for timely communication of information.

Description

technical field [0001] The invention relates to the technical field of navigation and communication, in particular to a communication method and system for sharing navigation information. Background technique [0002] At present, navigation terminals have been widely used in daily life, and navigation terminals generally include vehicle navigation terminals, portable navigation terminals, and navigation terminals installed in mobile terminals with communication functions. The navigation terminal can provide the user with various alternative driving routes according to the destination information input by the user. At the same time, the navigation terminal connected to the mobile network can realize functions such as map update and personalized setting. [0003] However, the functions of existing navigation terminals are limited to single-person or single-vehicle modes, and cannot meet the needs of group navigation when any group travel activities such as tour groups, small-...

AI Technical Summary

Problems solved by technology

[0003] However, the functions of existing navigation terminals are limited to single-person or single-vehicle modes, which cannot meet the needs of group navigation for any group travel activities such as tour groups, small-scale military operations, and self-driving tours.

Since the navigation terminal can provide a variety of routes to the destination, different navigation terminals may choose different navigation routes during group activities, resulting in inconsistent routes. However, each navigation terminal is set to the same navigation route. Team members need to inform each other about the route, and the user experience is poor

Especially when there is an emergency and the navigation route needs to be changed, it is not easy to notify each member in the group in time, which may easily cause members to leave the team, and the location information of other members cannot be obtained through the navigation device

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
