Terminal Position Acquisition via Neighboring Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for determining a terminal's position using IP addresses are unreliable due to incorrect or unattainable information, especially in varying network environments, leading to difficulties in providing local information to users.
Innovation Solution
A method and system that request and receive position information from neighboring terminals with functional position determination modules, such as GPS or Wi-Fi positioning systems, to accurately determine the position of terminals that cannot do so themselves, using a position information acquisition system with units for requesting, receiving, and providing services based on the determined location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If position information is determined using IP address, then the system can operate without additional hardware, but the position information becomes incorrect or unattainable in varying network environments
Solution Approach 1:
The patent introduces a position information acquisition server as an intermediary that mediates between terminals without position determination capabilities and terminals with position determination capabilities. The server receives position information from neighboring terminals and provides it to terminals that cannot determine their own position, thereby improving reliability without requiring complex hardware modifications to individual terminals.
Solution Approach 2:
The position information acquisition server performs multiple functions: it acts as a position determination service provider, a data relay between terminals, and a coordinator for position information sharing. This multi-functionality allows the system to improve position accuracy across different terminal types without increasing individual device complexity.
2Reliability
If terminal requests position information from neighboring terminal, then position information can be acquired when terminal lacks position determination module, but additional communication protocols and applications are required
Solution Approach 1:
The system enables neighboring terminals to provide position information services to terminals that cannot determine their own position. The terminal with position determination capability automatically shares its position information with the server, which then relays it to the requesting terminal, creating a self-service mechanism that improves availability without requiring complex user intervention.
Solution Approach 2:
The patent implements a feedback mechanism where the position information acquisition server receives position information from neighboring terminals and uses this feedback to provide accurate position data to terminals that cannot determine their own position. This feedback loop ensures continuous availability of position information across the network.
3Ease of manufacture
If terminal uses IP address for position determination, then the method is simple to implement, but the position information becomes incorrect or unattainable according to network environment
Solution Approach 1:
The patent changes the parameter used for position determination from IP address to real position coordinates obtained from position determination modules. The position information acquisition server collects actual position data (latitude, longitude, or equivalent coordinates) from neighboring terminals and uses these updated parameters to provide accurate position information, thereby improving measurement precision while maintaining implementation simplicity through server-based coordination.
Data Source
AI summary
A method and system for acquiring a position of a terminal are provided. A position of a terminal incapable of measuring or transmitting its position may be determined by receiving position information of neighboring terminals located close to the terminal.
