Server Proximity Detection for Mobile Terminal Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems require user intervention to access data from a server, and data exchange between mobile terminals in close proximity is often incomplete due to short interaction times.
Innovation Solution
A communication system with a server apparatus that determines proximity between mobile terminals using GPS data and transmits preinstalled content data automatically when they are in close proximity, ensuring uninterrupted data transfer without user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic proximity-based data transmission is implemented, then user operation is eliminated and data transmission reliability is improved, but system complexity increases due to position data processing and automatic transmission control
Solution Approach 1:
The system automatically detects proximity between terminals using position data and initiates data transmission without user intervention. The server apparatus autonomously determines whether terminals are in close proximity and controls data transmission based on this determination, making the system self-serve the user's data exchange needs.
Solution Approach 2:
The server apparatus acts as an intermediary between mobile terminals, receiving position data from terminals, determining proximity relationships, and controlling data transmission. This intermediary handles the complexity of proximity detection and transmission control, shielding users from system complexity while enabling automatic operation.
2Reliability
If data transmission is initiated automatically based on proximity determination, then data exchange completeness is improved for brief encounters, but position data processing requirements and system resources increase
Solution Approach 1:
The server apparatus continuously receives and stores position data from terminals before data transmission is needed. By having position data readily available in advance, the server can immediately determine proximity and initiate data transmission without delay when terminals come into close proximity, ensuring complete data exchange even during brief encounters.
Solution Approach 2:
The system performs rapid proximity determination and initiates data transmission quickly when terminals are detected in close proximity. This fast response ensures that data exchange is completed within the brief time window when terminals are near each other, preventing data transmission interruption.
