Wi-Fi Direct Group Connection Management via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi direct connection methods require disconnecting from existing devices to connect to new devices, leading to inconvenient multiple connection operations.
Innovation Solution
A method and apparatus for Wi-Fi direct connection that detects group connection events, determines terminal operation modes, exchanges information, generates new groups, and maintains existing connections by resetting groups to connect to new devices without disconnecting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the portable terminal disconnects from the existing device to connect to the new device, then the terminal can connect to the new device, but the terminal loses the existing connection and requires multiple connection operations
Solution Approach 1:
The patent segments the connection management by introducing a group owner terminal that manages group connection information separately from individual terminal connections. When a new device connects, the group connection information is segmented and distributed to relevant terminals, allowing the portable terminal to maintain its existing connection while acquiring information about the new connection through the group structure.
2Ease of operation
If the portable terminal maintains connection to the existing device, then the existing connection is preserved, but the terminal cannot connect to the new device
Solution Approach 1:
The patent introduces a group owner terminal as an intermediary that mediates between the portable terminal and new devices. The group owner receives connection requests, manages group connection information, and distributes this information to group members. This intermediary structure allows the portable terminal to maintain its existing connection while still being able to connect to new devices through the group information management mechanism.
3Adaptability or versatility
If the terminal performs multiple connection operations to connect to various devices, then the terminal can communicate with different devices, but the operation process becomes complex and inconvenient
Solution Approach 1:
The patent applies preliminary action by having the group owner terminal pre-establish and manage the group connection information structure before individual connection requests occur. The group connection information is prepared and maintained in advance, so when a new device connects, the portable terminal can quickly acquire the necessary connection information through the pre-established group structure rather than performing complex multiple connection operations.

AI summary
A method and apparatus for a Wi-Fi direct connection are provided. The method for a Wi-Fi direct connection includes detecting an event for a group connection, determining whether a terminal belongs to a first group when the event for the group connection is detected, determining an operation mode within the first group when the terminal belongs to the group, exchanging group information or terminal information according to the determined operation mode within the first group, and comparing exchanged information, generating a new group according to the operation mode within the new group based on the compared information, and connecting the new group through a group reset according to the operation mode within the new group when the new group generation is completed.
