Shared AP List Communication for Serverless Device Context Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sharing context information among electronic devices incur latency and costs due to reliance on central servers for data exchange.
Innovation Solution
Electronic devices communicate directly through shared access points using multiple communication methods to facilitate peer-to-peer data sharing without server intervention, enabling continuity services like seamless document transfer and application operation across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If context information is shared using a central server, then data exchange between electronic devices is enabled, but latency occurs when obtaining context information and server usage costs money
Solution Approach 1:
The patent extracts the data exchange function from the central server infrastructure and implements it directly between electronic devices through access point lists. Devices share access point information and communicate peer-to-peer, eliminating the need for server-mediated data exchange and reducing latency.
Solution Approach 2:
The patent uses access point lists as an intermediary mechanism to enable direct communication between devices. Instead of using a central server as mediator, devices exchange access point information which serves as a common reference point for establishing direct connections, thereby eliminating server costs and latency.
2Reliability
If context information is shared using a central server, then data exchange between electronic devices is enabled, but server usage incurs costs
Solution Approach 1:
The patent enables electronic devices to serve themselves by directly sharing context information through access point lists without requiring external server infrastructure. Devices autonomously exchange data using their own resources, eliminating server usage costs while maintaining reliable data exchange capability.
3Productivity
If electronic devices communicate through shared access points using peer-to-peer method, then latency is reduced and server costs are eliminated, but devices must support multiple communication methods and coordinate access point selection
Solution Approach 1:
The patent requires electronic devices to support multiple communication methods (first and second communication methods) to ensure universal compatibility. Devices can exchange access point lists through one method and establish data connections through another, providing flexible multi-functional communication capability that resolves the latency-speed contradiction.
Solution Approach 2:
The patent implements dynamic communication method selection where devices can switch between different communication protocols based on the operational phase (discovery vs. data transfer). This dynamic adaptation allows devices to optimize for speed during data sharing while maintaining compatibility through multiple supported protocols.
