Location Area Segmentation for Timely Help-Seeking in LBS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based service technologies fail to timely publish help-seeking information between user terminals located in close geographic proximity.
Innovation Solution
A method and system that involves receiving help-seeking information, determining the location area of the first terminal, and sending this information to a second terminal within the same area, with response information being relayed back through a server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If help-seeking information is published through existing location-based service systems, then users can find help from nearby terminals, but the information cannot be published in time when help is needed
Solution Approach 1:
The system performs preliminary actions by pre-establishing location area divisions and maintaining updated location information of terminals in each area. When help is needed, the system can immediately query and transmit information to appropriate terminals within the pre-defined location area, eliminating the need for real-time global search and enabling timely information publication.
Solution Approach 2:
The patent segments the service area into multiple location areas, each managed independently with its own terminal list. This segmentation allows the system to quickly identify and transmit help information only to terminals within the relevant location area rather than searching the entire service area, significantly reducing publication time while maintaining reliable local help connection.
2Speed
If the system searches for nearby terminals globally when help is needed, then comprehensive help can be found, but the response time is delayed
Solution Approach 1:
The patent divides the service area into multiple location areas and maintains separate terminal lists for each area. When help is needed, the system queries only the relevant location area's terminal list rather than performing a global search, significantly reducing search time and improving information transmission speed without substantially increasing system complexity.
Solution Approach 2:
The system performs preliminary organization of terminals into location area groups with updated location information stored in advance. This pre-arranged structure enables rapid query and transmission to appropriate terminals when help is needed, achieving fast response without complex real-time search mechanisms.

AI summary
Embodiments of the present invention disclose a help-seeking method, device and system based on a location based service, which relate to the field of location based service technologies. Help-seeking information sent by a first terminal is received, and a location area of the first terminal is determined according to the help-seeking information; the help-seeking information is sent to a second terminal located in the same location area as the first terminal; and response information fed back by the second terminal is received, and the response information is sent to the first terminal. The problem that, in the prior art, help-seeking information cannot be published in time when a user terminal needs help from another user terminal in the neighborhood of the user terminal in terms of geographic location is solved. The present invention may be applied in a mobile user terminal, for example, a smart phone terminal.
