Wireless Device Scan Initiation and Termination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for initiating and terminating wireless device scans are limited by the number of scans allowed in a specified period, leading to delayed responses due to power consumption constraints, causing issues with scan initiation and termination.
Innovation Solution
Implementing a method that includes an upper limit for scan initiations within a period, storing historical initiation time points, and calculating time differences to determine when to terminate or continue scans, allowing for timely response to scan instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wireless communication component actively initiates scans to establish connections, then the connection establishment capability is improved, but the power consumption increases
Solution Approach 1:
The patent implements periodic scanning by allowing a limited number of scan initiations within a specified time period. The scanning component is configured to initiate scans only when the number of scans in the current period has not reached a predefined threshold, creating a periodic rather than continuous scanning pattern. This reduces power consumption while maintaining connection establishment capability.
2Use of energy by moving object
If the wireless communication component is limited in the number of scan initiations per period to reduce power consumption, then the power consumption is reduced, but the response speed to scan instructions deteriorates
Solution Approach 1:
The patent records the initiation time of each scan in a sequence, maintaining historical scan timing information in advance. When a scan termination instruction is received, the system calculates the time difference between the current time and the earliest recorded initiation time to determine whether to terminate the ongoing scan. This preliminary recording of timing data enables rapid response to termination instructions without waiting for scan completion, thus improving response speed while maintaining power efficiency.

AI summary
The embodiments of the present disclosure disclose a method for initiating and terminating a scan of a wireless device, and a wireless device. A sequence of time-of-initiation including a specified number of historical initiation time points is provided. The method comprises: receiving a scan OFF instruction from a requester; calculating a time difference between a current time point and an earliest historical initiation time point in the sequence of time-of-initiation, and comparing the time difference with the specified period to determine whether to terminate a current scan, in response to the scan OFF instruction; and continuing with the current scan until a target time point, and terminating the current scan at the target time point, if it is determined not to terminate the current scan. The technical solutions provided in the embodiments can improve speed of response of the wireless device to the scan ON and OFF instructions.
