Wireless Terminal Detection Timeout Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In short-range wireless communication systems like Bluetooth, the detection process for wireless communication terminals is time-consuming due to the need for a long timeout period, which is inefficient for applications requiring quick data transmission and selective terminal selection.
Innovation Solution
An information processing device with a terminal detection section that transmits inquiry packets, suspends detection if a terminal is found within a predetermined timeout, and restarts detection for other terminals after data communication is completed, allowing immediate data communication with detected terminals without waiting for a timeout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long timeout period is used to ensure complete detection of all wireless communication terminals, then detection reliability is improved, but detection time is significantly increased
Solution Approach 1:
The patent applies preliminary action by detecting wireless communication terminals in advance before data communication is required. The terminal detection section performs detection proactively, and once terminals are detected, the detection is suspended and data communication is immediately initiated with the detected terminals, eliminating the need to wait for timeout completion.
Solution Approach 2:
The patent implements dynamics by making the detection process adaptive and flexible. The terminal detection suspension section dynamically suspends detection when terminals are detected within the timeout period, allowing the system to switch between detection mode and data communication mode based on real-time conditions, thereby optimizing both reliability and time efficiency.
2Measurement precision
If detection processing is performed thoroughly to identify all available terminals, then selection accuracy is improved, but processing time is increased
Solution Approach 1:
The system performs terminal detection in advance as a preliminary action. By detecting terminals before data communication is needed and suspending detection once terminals are found within the timeout period, the system ensures accurate terminal identification while significantly reducing the time required for communication setup.
Solution Approach 2:
The patent applies partial action by not requiring complete detection of all possible terminals. Instead, detecting terminals within the timeout period is sufficient to proceed with data communication. The system accepts partial detection results when they enable immediate communication, rather than waiting for exhaustive detection.
3Speed
If the detection process is suspended to enable immediate data communication, then communication speed is improved, but detection completeness may be compromised
Solution Approach 1:
The terminal detection section performs detection as a preliminary action before data communication. By completing detection within the timeout period and then suspending detection to initiate immediate data communication, the system ensures both detection completeness (within acceptable limits) and communication speed.
Solution Approach 2:
The system uses feedback mechanisms where the terminal detection suspension section monitors detection progress and data communication status. When terminals are detected within the timeout period, the system receives feedback and suspends detection to enable immediate data communication, dynamically balancing completeness and speed based on real-time conditions.

AI summary
Apparatus includes a section which transmits an inquiry packet for inquiry as to whether any wireless communication terminal exists within such range as to be able to communicate with the apparatus, detects each of a plurality of wireless data communication terminals transmitting inquiry response packets in response to the packet, and completes the detection of wireless communication terminals if no wireless communication terminal is detected within a predetermined detection completion timeout period after starting the transmission of the packet, a section which suspends the detection of wireless communication terminals performed by the terminal detection section if a wireless communication terminal is detected, a section which performs wireless data communication with the detected wireless communication terminal while the detection of wireless communication terminals is suspended, and a section which restarts detection of other wireless communication terminals by the terminal detection section after the completion of the data communication is detected.
