Mutual navigation method and system and movable terminal

Abstract

The invention discloses a mutual navigation method comprising the following steps of: receiving a navigation assistance request message of a requesting terminal; calling a navigation database to plan paths according to the navigation assistance request message; obtaining the current position information of the requesting terminal in real time; and transmitting navigation information to the requesting terminal according to the planned paths in real time. Correspondingly, the invention also discloses a movable terminal and a mutual navigation system. The invention is capable of realizing the mutual navigation among movable terminals, increasing the navigation position accuracy of the movable terminals, promoting the development of navigation application service and increasing user experience.

Description

technical field [0001] The present invention relates to the technical field of navigation, in particular to a mutual aid navigation method, system and mobile terminal. Background technique [0002] Mobile positioning service refers to the use of specific positioning technology to obtain mobile terminal information through the operator's network (such as: GSM (Global System for Mobile Communications, Global System for Mobile Communications) network, CDMA (Code Division Multiple Access, Code Division Multiple Access) network) The location information (latitude and longitude coordinates), with the support of the electronic map platform, provides terminal users with positioning services for mobile terminals. The mobile positioning service implemented through the operator's network only needs to open the relevant service business, and does not need the hardware support of the mobile terminal. [0003] With the development of navigation technology, more and more mobile terminals ...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the limitation of network bandwidth and the influence of geographical information collection and update, the existing mobile positioning by operators is limited to terminal positioning services, and provides terminal users with some surrounding shopping malls, restaurants and other service facilities through electronic map services , but it cannot provide navigation services for mobile terminals, and the positioning accuracy of mobile positioning services for mobile terminals is low, and user experience is not high;

[0006] 2. Although the existing navigation application services based on satellite navigation systems can provide more accurate navigation and positioning for mobile terminals, they require the hardware support of mobile terminals and the cost is relatively high; some mobile terminals themselves do not have the ability to perform navigation services. Thus limiting the development of navigation application services
