Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current location-based services (LBS) face issues with inaccurate positioning, unclear location descriptions, and lack of specificity in nearby information, particularly in mobile communications, where single base station or WIFI-based solutions fail to provide precise and personalized location information to users.
Innovation Solution
Integrating base station, WIFI, and GPS information to acquire precise terminal positioning, establishing correlation relationships among these references for cross-validation, and using user behavior data to provide accurate and personalized location-based services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If base station information is used for positioning, then the coverage area is large, but the positioning accuracy deteriorates (error within 800m)
Solution Approach 1:
The patent combines multiple positioning reference systems (base station, WIFI, GPS) into an integrated positioning system. By merging these different positioning technologies, the system achieves both wide coverage (from base station) and high accuracy (from WIFI and GPS), resolving the contradiction between coverage area and positioning accuracy.
Solution Approach 2:
The patent creates a composite positioning system that integrates multiple positioning technologies with different characteristics. Each positioning technology contributes its strengths: base station provides coverage, WIFI provides medium accuracy, and GPS provides high accuracy. This composite approach allows the system to achieve both large coverage and high positioning accuracy simultaneously.
2Measurement precision
If WIFI information is used for positioning, then the positioning accuracy improves (error within 50m), but the device complexity increases
Solution Approach 1:
The patent implements a dynamic positioning system that adaptively selects and combines positioning references based on availability and accuracy requirements. The system dynamically adjusts which positioning technologies to use (base station alone, base station + WIFI, or all three), reducing unnecessary complexity while maintaining high accuracy when needed.
Solution Approach 2:
The patent segments the positioning system into modular components (base station module, WIFI module, GPS module) that can be independently selected and combined. This segmentation allows the system to include WIFI positioning only when high accuracy is required, reducing overall system complexity while maintaining the capability for high-accuracy positioning.
3Device complexity
If single positioning reference is used, then the device complexity is low, but the positioning accuracy deteriorates
Solution Approach 1:
The patent merges multiple positioning references (base station, WIFI, GPS) into a unified positioning system that processes all available references simultaneously. This merging enables the system to achieve high positioning accuracy by combining the strengths of different technologies without requiring complex separate systems for each positioning method.
Solution Approach 2:
The patent creates a universal positioning system that can operate with any combination of positioning references (base station alone, WIFI alone, GPS alone, or any combination). This multi-functionality allows the system to achieve high accuracy when multiple references are available while maintaining simplicity when only one reference is available, resolving the contradiction between complexity and accuracy.
4Device complexity
If location description is based on base station accuracy, then the system is simple, but the location description becomes unclear and inaccurate
Solution Approach 1:
The patent implements feedback mechanisms where user corrections and confirmations are used to refine location descriptions. The system provides location information to users and incorporates user feedback to improve the accuracy and appropriateness of location descriptions, ensuring that descriptions match user expectations while maintaining system simplicity.
Solution Approach 2:
The patent dynamically changes the level of location description detail based on positioning accuracy and user context. When positioning accuracy is high, more specific location descriptions are provided; when accuracy is lower, broader area descriptions are used. This parameter adjustment ensures accurate location descriptions without requiring complex description systems.

AI summary
The present invention provides a precise location-based information service method and apparatus for mobile terminal browser users. The method includes: acquiring at least two types of positioning references based upon a positioning service request from a user; establishing correlation relationships among the positioning references based on the acquired positioning references; and performing integrated positioning and cross-validation on a precise location of the user based on the correlation relationships to determine final positioning service information. This invention can implement precise location-based services (LBS) and precise Point of Interest (POI) push service by analysis and extraction of the user's location information and behavioral data acquired and accumulated with the user's consent. This satisfies the needs of the mobile phone browser user for precise LBS and personalized nearby information service.
