Communicating Apparatus Mode Matching for Wireless Connection Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the mixing of different operation modes between devices can lead to failures in wireless connection and subsequent processing due to parameter acquisition errors, as devices may transmit probe response commands outside the standard range defined by their operating mode, resulting in uninterpretable information being responded to with interpretable information.
Innovation Solution
A communicating apparatus and method that determines whether the communication mode of a partner device matches its own mode before transmitting a response command, ensuring that only compatible mode-matched responses are sent, thereby preventing errors in wireless connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a probe response command is transmitted in response to a probe request command using information within the range defined by the self apparatus's operation mode, then the device can respond to requests from devices operating in different modes, but wireless connection may fail due to parameter acquisition errors or processing failures
Solution Approach 1:
The determination unit checks whether the partner apparatus's communication mode matches the self apparatus's communication mode before transmitting a probe response command. This preliminary verification prevents mode mismatches that would cause connection failures, while still allowing responses to compatible devices.
Solution Approach 2:
The system provides feedback by determining mode compatibility before responding. The response control unit uses this feedback to decide whether to transmit a probe response command, ensuring that responses are only sent to devices with matching communication modes, thereby preventing parameter acquisition errors.
2Adaptability or versatility
If a probe response command is transmitted using information added to the probe request command that includes uninterpretable information, then the device can respond to extended Wi-Fi Direct compatible apparatus, but subsequent processing may fail
Solution Approach 1:
The determination unit performs a preliminary check to verify that the communication modes match before the self apparatus transmits a probe response command. This prevents the self apparatus from responding to extended Wi-Fi Direct compatible apparatus with non-extended mode information, avoiding subsequent processing failures.
Solution Approach 2:
The system applies different response behaviors based on the local quality of mode compatibility. When modes match, the self apparatus responds with appropriate information; when modes don't match (such as responding to extended apparatus with non-extended information), the self apparatus withholds response to prevent errors.

AI summary
A communicating apparatus receives a request command which requires a response, and determines whether the communication mode of a partner apparatus corresponding to the request command matches a communication mode executed by the self communicating apparatus. If it is determined that the communication mode of the partner apparatus matches the communication mode executed by the self communicating apparatus, the communicating apparatus transmits a response command to the request command. If it is determined that the communication mode of the partner apparatus does not match the communication mode executed by the self communicating apparatus, the communicating apparatus transmits no response command to the request command.
