Wireless Communication Failure Detection During Power-Saving Wake-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing failure detection technologies in wireless communication systems, such as Wi-Fi, are inadequate in accurately detecting communication failures, leading to potential reductions in user convenience and efficiency.
Innovation Solution
An electronic apparatus equipped with a communication controller that performs a first failure detection process by transmitting a signal to search for a communication apparatus upon a shift from a power-saving mode to a non-power-saving mode, based on the receipt of a response, and a second detection process involving periodic packet transmission to detect failures, with recovery processes to resolve detected issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If failure detection is performed continuously to ensure accurate detection, then detection reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic failure detection by transitioning the communication connection between power-saving mode and non-power-saving mode. The controller sends signals at specific intervals (when mode transition occurs) rather than continuously, thereby maintaining detection capability while reducing overall power consumption. This periodic signaling approach allows the system to balance between reliable failure detection and energy efficiency.
2Loss of time
If failure detection signal is transmitted frequently to ensure early detection, then detection speed is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary failure detection actions by monitoring mode transitions between power-saving and non-power-saving states. When such a transition occurs, the controller proactively sends a detection signal before actual communication failures can impact user operations. This preliminary monitoring approach enables early failure detection without requiring continuous high-power signaling.
3Use of energy by moving object
If power-saving mode is maintained to reduce power consumption, then energy efficiency is improved, but failure detection capability deteriorates
Solution Approach 1:
The patent employs dynamic communication mode switching between power-saving mode and non-power-saving mode. The system adaptively transitions between these modes based on operational needs, using power-saving mode during idle periods to conserve energy and non-power-saving mode when detection or communication is required. This dynamic switching enables the system to maintain failure detection capability while optimizing power consumption throughout different operational states.

AI summary
An electronic apparatus 100 includes a wireless communicator 120 that performs wireless communication with a communication apparatus 200, and a processing section 110 that includes a communication controller 114 that controls communication of the wireless communicator 120. When an event that causes a shift of a communication connection between the processing section 110 and the wireless communicator 120 from a power-saving mode to a non-power-saving mode occurs, the communication controller 114 transmits a signal for searching for the communication apparatus 200 and detects a failure of the wireless communication depending on whether a response to the signal is received from the communication apparatus 200.
