Wireless Interface Selection for Direct Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing apparatuses with multiple wireless interfaces face challenges in selecting the appropriate interface for direct connections without disrupting existing infrastructure connections, particularly when switching between infrastructure and direct connection methods.
Innovation Solution
A method is implemented to determine which wireless interface is suitable for direct connection by checking if each interface is unconnected or already directly connected, allowing the system to select one interface for direct connection when multiple interfaces meet the criteria, thereby maintaining continuous internet access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single wireless interface is used to connect to a communication device via direct connection, then direct connection capability is achieved, but connection to other devices including Internet access is disconnected
Solution Approach 1:
The system divides the wireless communication function into multiple independent wireless interfaces. Each interface can operate independently to handle different connection types (direct connection vs. infrastructure connection), allowing simultaneous maintenance of both Internet access and direct connection capabilities without interference between them.
2Adaptability or versatility
If multiple wireless interfaces are added to enable simultaneous connections, then connection versatility is improved, but device complexity increases
Solution Approach 1:
The control unit automatically manages the selection and configuration of wireless interfaces based on connection requirements. The system self-determines which interface should handle direct connections versus infrastructure connections, eliminating the need for manual user configuration and reducing the perceived complexity for users while maintaining high adaptability.
3Reliability
If wireless interfaces are dynamically selected for direct connection, then connection reliability is improved, but control complexity increases
Solution Approach 1:
The control unit continuously monitors the connection status of each wireless interface and uses this feedback information to make intelligent selection decisions. When a direct connection is requested, the system checks which interfaces are available (not connected to infrastructure networks) and selects the appropriate one, ensuring reliable connection establishment while maintaining simple control logic.

AI summary
A method includes determining whether a plurality of wireless interfaces of an information processing apparatus is in a state of being a target for direct connection to a communication apparatus via a wireless LAN, checking whether a number of the wireless interfaces determined as being in the state of the target for the direct connection is plural, and deciding from the plurality of wireless interfaces in the state of being the target for the direct connection, one wireless interface to be directly connected to the communication apparatus in a case where the number of the wireless interfaces determined to be in the state of being the target for the direct connection is plural.
