Terminal Positioning via Server Triangulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based services (LBS) technologies are limited as they require satellite positioning modules and can fail to accurately position terminals without these modules or in adverse network environments, leading to incomplete or delayed location information.
Innovation Solution
A method and device for positioning terminals that obtain location information of positioned terminals and relevance information to determine the location of associated terminals, even if they lack satellite positioning modules or have poor network conditions, by using a server and communication network to process location and relevance information, including social relationships and network equipment data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite positioning modules are used for positioning, then positioning accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces a server as an intermediary that performs positioning calculations centrally. Instead of requiring satellite positioning modules in each terminal device, the server receives location data from multiple access points and calculates positions using triangulation algorithms, thereby eliminating the need for complex satellite modules in user devices while maintaining positioning accuracy
Solution Approach 2:
The patent replaces the mechanical/satellite-based positioning system with a network-based computational system. Positioning is achieved through signal strength measurements from wireless access points and server-side calculations, substituting the need for satellite modules and complex terminal-based positioning hardware with a simpler network infrastructure approach
2Reliability
If satellite positioning modules are required, then positioning reliability is improved, but adaptability to different terminal types deteriorates
Solution Approach 1:
The patent creates a universal positioning system that works across multiple terminal types (mobile phones, tablets, PCs, set-top boxes) without requiring satellite positioning modules. The server-based approach using wireless network infrastructure provides multi-functional positioning capability that adapts to different devices and usage scenarios, eliminating the need for device-specific satellite hardware
3Loss of time
If terminal equipment information transmission frequency is increased, then positioning timeliness is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic positioning updates where terminals transmit location information at predetermined time intervals rather than continuously. The server maintains positioning accuracy by receiving these periodic updates and can interpolate positions between updates, reducing terminal energy consumption while maintaining timely positioning information
Solution Approach 2:
The server performs the computationally intensive positioning calculations and maintains the positioning information, reducing the processing burden and energy consumption at the terminal side. The terminal simply needs to transmit raw location data periodically, while the server handles the complex triangulation and position maintenance
