Dynamic Geographic Zone Thresholds for Location-Based Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geographic location-based services (LBS) are limited to providing information within a fixed area based on the user's location, failing to dynamically adapt to different user needs and providing unsatisfactory product and merchant information.
Innovation Solution
A method and system that look up geographic location zone threshold values corresponding to user needs, allowing mobile terminal users to receive information from various ranges based on need information, using a server that communicates with mobile terminals via a wireless network to search for target information within specified zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing LBS applications use a fixed distance radius to search for nearby merchants or products, then the search area is clearly defined and easy to implement, but the service cannot flexibly adapt to different user needs and provides unsatisfactory information
Solution Approach 1:
The patent pre-establishes a correspondence table between different information categories (such as hotels, restaurants, shopping) and their respective geographic location zone threshold values. This preliminary action allows the system to quickly retrieve appropriate threshold values without complex real-time calculations, thereby improving adaptability while controlling system complexity.
Solution Approach 2:
The patent changes the fixed radius parameter into a dynamic parameter by introducing category-specific threshold values. Different information categories have different threshold values (e.g., 1km for hotels, 500m for restaurants), allowing the search radius to adapt to user needs based on the category of information being sought.
2Measurement precision
If the search radius is fixed at a small distance, then the information provided is highly relevant to the user's current location, but users in remote areas or those seeking broader options receive insufficient information
Solution Approach 1:
The patent applies different search radius thresholds to different information categories based on their local characteristics. For example, hotels may have a 1km threshold while restaurants have a 500m threshold. This local quality approach ensures that each category of information is searched with an appropriately scaled radius, balancing relevance with comprehensiveness.
3Quantity of substance
If the search area is expanded to cover larger distances, then more diverse product and merchant information is available, but the information becomes less relevant to the user's immediate needs
Solution Approach 1:
The patent segments the search area into multiple concentric zones with different threshold values for different information categories. This segmentation allows the system to provide both nearby highly relevant information and farther away diverse information in a structured manner, satisfying both relevance and quantity requirements.

AI summary
Embodiments of the present application relate to an information searching method based on geographic location, an information searching system based on geographic location, and a computer program product for searching for information based on geographic location. An information searching method based on geographic location is provided. The method includes acquiring need information and geographic location information corresponding to a mobile terminal user, looking up a preset geographic location zone threshold value based on the need information, preconfigured mappings of preset geographical location zone information and category information, and searching for target information corresponding to the need information based on the geographic location information of the mobile terminal user and the preset geographic location zone threshold value.
