Wi-Fi Direct Group Profile Management for Automatic P2P Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Wi-Fi direct communication systems, users face inconvenience when reconnecting to previously established peer-to-peer (P2P) device groups, as they must manually discover and select devices each time, leading to inefficiencies in regenerating favorite groups.
Innovation Solution
A method and apparatus for managing a group profile in Wi-Fi direct communication systems, allowing users to profile frequently used P2P groups, operation modes, credentials, and applications, enabling automatic regeneration of favorite groups by setting the device to an automatic group owner and updating profile information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual device discovery and selection is used for reconnecting to P2P groups, then connection reliability is ensured through user confirmation, but connection time increases and user convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by storing profile information of favorite P2P groups including device lists, operation modes, and credentials before disconnection occurs. When reconnecting, the system retrieves and applies this pre-stored information automatically, eliminating the need for manual device discovery and selection, thus reducing connection time while maintaining reliability through the structured profile data.
2Ease of operation
If automatic group owner mode is implemented, then ease of operation improves by eliminating manual device selection, but device complexity increases due to profile management requirements
Solution Approach 1:
The system implements self-service by automatically managing group regeneration using stored profile information. The electronic device autonomously retrieves favorite group profiles, determines operation modes, and executes reconnection without user intervention. This self-service capability improves ease of operation while the profile management complexity is encapsulated within the device's automated processes rather than requiring user-facing complexity.
3Productivity
If profile information is stored and managed, then productivity improves by enabling quick group regeneration, but loss of information increases due to additional data storage requirements
Solution Approach 1:
The system extracts only the essential information needed for group regeneration and stores it in structured profiles. These profiles contain specifically extracted elements such as device lists, operation modes, and credentials, rather than storing complete group configurations. This selective extraction approach improves productivity by enabling quick regeneration while minimizing information storage overhead by storing only the necessary regenerated parameters.

AI summary
A Wi-Fi direct communication system and method are used for regenerating a group of an electronic device in the Wi-Fi direct communication system, and an operation mode is determined in information of an obtained profile. When the operation mode is a group owner mode, the electronic device is set to an automatic group owner. At least one device included in the profile information is retrieved, and the retrieved device is invited to the group. When the invitation is completed, the group regeneration is completed.
