Shared Access Point Communication for Low-Latency Device Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sharing context information among electronic devices involve central servers, leading to latency and costs.
Innovation Solution
Electronic devices communicate directly through shared access points using Wi-Fi and Bluetooth Low Energy (BLE) to exchange data without a central server, allowing them to determine a common access point based on matching account information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If context information is shared using a central server, then data sharing capability is provided, but latency occurs when obtaining context information and costs are incurred
Solution Approach 1:
The patent extracts the data sharing function from the central server and implements it directly between electronic devices through peer-to-peer communication. Devices exchange context information directly without routing through the server, eliminating server-related latency while maintaining data sharing capability.
Solution Approach 2:
The patent introduces an access point as an intermediary to facilitate direct communication between electronic devices. The access point enables devices to discover and communicate with each other directly, serving as a mediator that removes the need for central server intervention and reduces latency.
2Reliability
If context information is shared using a central server, then data sharing capability is provided, but costs are incurred for server usage
Solution Approach 1:
The patent removes the central server component from the data sharing architecture, allowing devices to share context information directly. This extraction eliminates server usage costs while preserving the essential data sharing functionality through device-to-device communication.
Solution Approach 2:
The patent enables electronic devices to perform data sharing autonomously without relying on external server infrastructure. Devices self-manage the context information exchange process, eliminating the need to pay for server resources and enabling cost-free data sharing.
3Loss of time
If electronic devices communicate directly without a central server, then latency is reduced and costs are eliminated, but device complexity increases for managing direct connections
Solution Approach 1:
The patent uses the access point as an intermediary to simplify connection management. The access point handles device discovery, connection establishment, and communication coordination, reducing the complexity burden on individual devices while enabling direct communication that lowers latency.
Solution Approach 2:
The patent implements feedback mechanisms where devices exchange connection status and communication quality information through the access point. This feedback enables automatic connection optimization and simplifies management by allowing devices to adapt to changing network conditions without complex manual configuration.
