Wi-Fi Direct Group Owner Selection via Service-Specific Intent Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi Direct networks lack the ability to designate a group owner based on the type of service being connected, leading to inefficient group management and suboptimal device roles during service connections.
Innovation Solution
A method and apparatus that determine a group owner by searching for intent values corresponding to services and exchanging negotiation messages between devices, allowing for designation based on service types through a comparison of intent values stored in a table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If devices exchange intent values to determine group owner in Wi-Fi Direct connection, then connection establishment is enabled, but efficient group management and optimal device role designation cannot be guaranteed
Solution Approach 1:
The patent applies local quality by making the group owner determination process service-specific. Instead of using a uniform intent value exchange for all services, the system now determines group owners based on the specific service type being established (e.g., printing, scanning, file transfer). This allows different services to have optimized group owner selection criteria, improving adaptability while maintaining connection efficiency.
Solution Approach 2:
The patent changes the parameter used for group owner determination from generic intent values to service-type-specific parameters. The system now considers the type of service being established when determining group owner authority, allowing the determination criteria to adapt dynamically based on service requirements rather than using fixed intent value comparison.
2Reliability
If a high-performance device operates as group owner, then service performance is optimized, but the system lacks mechanism to guarantee suitable device designation
Solution Approach 1:
The patent enables devices to self-assess and indicate their suitability for group owner roles based on service type. Instead of requiring complex external evaluation or manual configuration, devices automatically determine their own intent to serve as group owner for specific services through service-type-based intent value exchange, simplifying the designation mechanism while ensuring reliable performance optimization.
Solution Approach 2:
The patent performs preliminary service type identification and intent value determination before finalizing the group owner designation. By evaluating service types and device capabilities in advance through structured negotiation messages, the system ensures that the most suitable device is designated as group owner before the connection is fully established, improving reliability without adding operational complexity.
3Ease of operation
If generic intent value exchange is used for group owner determination, then connection process is simple, but service-specific optimization is lost
Solution Approach 1:
The patent creates a universal service-type-based negotiation framework that can handle multiple different services (printing, scanning, file transfer, etc.) through a common intent value exchange mechanism. The system maintains simplicity by using the same basic negotiation message structure across all services, while achieving service-specific optimization through service-type-aware intent value determination.
Solution Approach 2:
The patent makes the group owner determination process dynamic by adapting intent value exchange to the specific service type being established. Rather than using fixed, static criteria, the system dynamically adjusts the determination process based on service requirements, allowing simple operation for common services while optimizing for specialized service needs.

AI summary
A method and a first device for determining a group owner during establishment of a local-wireless communication connection are provided. The method includes searching for a second device that supports the local-wireless communication connection; searching, if the second device is found, for services supportable by the second device; determining an intent value of the first device corresponding to a group owner authority with respect to a service to be connected among the found supportable services; transmitting, to the second device, a negotiation message including the determined intent value of the first device; receiving, from the second device, a negotiation message including an intent value of the second device; and determining, from among the first device and the second device, a device having the group owner authority by comparing the determined intent value of the first device with the intent value of the second device.
