Terminal Location Acquisition via Intermediary Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to provide accurate location information for terminals with no or low-accuracy positioning capability, leading to inaccuracies in location-based applications.
Innovation Solution
A method where a first terminal requests and receives location information from a second terminal with accurate positioning capabilities, using this information for location-based operations, potentially through communication protocols like Bluetooth, infrared, or a shared user account via a messaging server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IP address-based location determination is used for terminals with no or low-accuracy positioning capability, then the location can be obtained without additional positioning hardware, but the location accuracy is relatively low and covers a large area
Solution Approach 1:
The patent introduces a second terminal as an intermediary that possesses accurate positioning capabilities. This second terminal assists the first terminal (which lacks positioning capability) by providing its own location information or by relayed positioning data, thereby enabling the first terminal to obtain accurate location information without requiring built-in positioning hardware
Solution Approach 2:
The patent employs a approach where the location information of the second terminal (which has accurate positioning) is copied or transferred to the first terminal. The first terminal uses the second terminal's location data as a substitute for its own positioning, effectively borrowing the positioning capability of another device
2Measurement precision
If a second terminal with accurate positioning is introduced to assist the first terminal, then location accuracy is improved, but the system complexity increases due to additional communication and coordination requirements
Solution Approach 1:
The second terminal is designed to serve multiple functions: it acts as both a user device and a positioning assistant. When not providing positioning assistance, it functions normally as a regular terminal. This multi-functionality reduces the need for dedicated positioning infrastructure and minimizes system complexity
Solution Approach 2:
The system enables terminals to self-organize into positioning pairs without requiring centralized coordination. The first terminal autonomously identifies and contacts a nearby second terminal for positioning assistance, and the second terminal autonomously provides its location data, reducing the need for complex system-wide coordination mechanisms

AI summary
This provides a terminal location obtaining method, device, and system. The method includes: a first terminal transmitting a location-obtaining request to a second terminal; the second terminal starting a positioning function to obtain the current location information of the second terminal, and transmitting the obtained location information of the second terminal to the first terminal; the first terminal using the location information of the second terminal as the location information of the first terminal, and performing a location-based application operation based on the location information. This can obtain relatively accurate location information of a terminal when the terminal is incapable of determining its own location when location determination is needed. This can also transmit the location information to a corresponding application server to avoid inaccuracy issues with determining a location based on the IP address of a terminal. This can facilitate an accurate location-based push message service.
