Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Wi-Fi Direct connections do not efficiently determine a group owner, leading to suboptimal network control and connectivity, as predetermined group owner intent values are used without consideration for specific service information or device conditions.
Innovation Solution
A method and device for inter-device communication that dynamically adjust group owner intent values based on service information, such as device type and Internet access needs, to determine a group owner suited to specific conditions, allowing for more efficient network management and connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If predetermined group owner intent values are used for Wi-Fi Direct connection, then the connection process is simple, but the network efficiency and group owner determination are suboptimal
Solution Approach 1:
The patent makes the group owner intent value dynamic by allowing devices to adjust their intent values based on service information and connection conditions. Instead of using fixed predetermined values, the system dynamically modifies intent values during the negotiation process to optimize network efficiency while maintaining operational simplicity.
Solution Approach 2:
The patent changes the parameter of group owner intent value from a fixed predetermined value to an adjustable value that can be modified based on service information. This parameter change enables the system to adapt to different connection scenarios and improve network efficiency without complicating the overall connection process.
2Device complexity
If predetermined group owner intent values are used, then the device complexity is low, but the adaptability to specific service conditions is poor
Solution Approach 1:
The system dynamically adjusts group owner intent values based on service information without requiring complex device architecture. The dynamic adjustment occurs through simple comparison and modification of intent values during the connection negotiation, maintaining low device complexity while improving adaptability.
Solution Approach 2:
By changing the intent value parameter based on service conditions, the system achieves adaptability without increasing device complexity. The patent modifies the intent value parameter dynamically based on received service information, allowing the same device to adapt to different service scenarios.
3Productivity
If service information is considered for group owner determination, then the network efficiency is improved, but the connection negotiation process becomes more complex
Solution Approach 1:
The patent performs preliminary action by having devices exchange service information early in the connection process, before the final group owner determination. This allows the system to use the service information for intent value adjustment without adding significant complexity to the negotiation process, as the information is gathered in advance.
Solution Approach 2:
The patent uses parameter changes to improve network efficiency by modifying intent values based on service information. This approach avoids the need for complex negotiation algorithms, instead relying on simple parameter adjustments that maintain process simplicity while achieving better network efficiency.
4Adaptability or versatility
If group owner intent values are dynamically adjusted, then the adaptability to specific conditions is improved, but the loss of time for negotiation increases
Solution Approach 1:
The patent performs preliminary exchange of service information and intent value adjustments during the initial connection phases, so that the dynamic adaptation does not require additional negotiation time. By integrating the adaptation process into existing negotiation steps, the system maintains fast connection while achieving better adaptability.
Solution Approach 2:
The patent uses efficient parameter changes that can be computed and exchanged quickly during the negotiation process. The intent value adjustment based on service information is designed to be a simple comparison and modification operation, minimizing the time added to the negotiation process while maximizing adaptability.

AI summary
A device and method for performing inter-device communication are disclosed. The inter-device communication method includes searching for a second device supporting inter-device communication, receiving service information from the searched second device, determining that one of the first and second devices is a group owner and the other is a group client to compare the received service information of the second device with service information of a first device, receiving a group owner intent value of the second device from the second device, and setting a group owner intent value of the first device such that the group owner intent value of the device determined as the group owner is greater than the group owner intent value of the device determined as the group client to compare the group owner intent value of the first device with the group owner intent value of the second device.
