Shared AP Matching for Direct Peer-to-Peer Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sharing context information among electronic devices involve central servers, leading to latency and costs, and lack direct peer-to-peer communication solutions.
Innovation Solution
Electronic devices equipped with dual communication modules and processors enable direct connection to a shared access point based on matching account information, allowing peer-to-peer data sharing without a central server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If context information is shared using a central server, then data sharing is enabled among electronic devices, but latency occurs when obtaining context information and server usage costs money
Solution Approach 1:
The patent extracts the central server from the data sharing process and replaces it with direct peer-to-peer communication between electronic devices through access point lists. Devices share access point information and connect directly to each other, eliminating the intermediary server that causes latency and costs.
Solution Approach 2:
The patent introduces access point lists as a new intermediary mechanism. Instead of using a central server for data sharing, devices exchange access point information and use these lists as mediators to establish direct connections, thereby reducing latency while maintaining data sharing capability.
2Reliability
If context information is shared using a central server, then data sharing is enabled among electronic devices, but server usage costs money
Solution Approach 1:
The patent removes the central server from the system architecture and replaces server-based data sharing with direct device-to-device communication through shared access point lists, eliminating server usage costs while preserving data sharing functionality.
Solution Approach 2:
Electronic devices perform data sharing autonomously by exchanging access point information and connecting directly to each other without requiring external server resources. Each device serves itself and other devices in the network, eliminating dependency on paid server infrastructure.
3Adaptability or versatility
If electronic devices connect to different access points, then devices can maintain independent connections, but direct peer-to-peer communication is not established
Solution Approach 1:
The patent merges access point lists from multiple devices and identifies common access points that both devices can use. By combining the connection options from both devices and selecting a shared access point, the system enables direct peer-to-peer communication while respecting each device's independent connection capabilities.

AI summary
According to various embodiments, an electronic device may include: a communication module comprising communication circuitry configured to support a first communication method and a second communication method, a memory, and a processor operatively connected to the communication module and the memory. The processor may be configured to: control the electronic device to connect to a first AP included in a first AP list based on the first communication method, receive a signal based on the second communication method transmitted from an external electronic device, obtain account information about the external electronic device and a second AP list including information about a second AP connected with the external electronic device from the external electronic device based on the second communication method upon receiving the signal, determine at least one AP, based on the first AP list and the second AP list based on account information about the electronic device and the account information about the external electronic device at least partly matching, and control the electronic device to perform wireless communication with the external electronic device based on the first communication method through the determined AP.
