Network Controller Time Division Scheme for Wireless Video Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless video monitoring technologies suffer from network congestion and user experience quality degradation due to the lack of proactive control policies, which only respond after quality decline, failing to address congestion effectively during the adjustment period.
Innovation Solution
A control method and apparatus that implement a time division scheme for stations in a cruise monitoring period, configuring control information to manage operating status during adjustment periods, including priority, frame discard, ACK policies, and bit rate adjustments, to alleviate network congestion before it occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control policy is applied only after user experience quality declines, then the system responds to quality degradation, but the user experience quality has already deteriorated for a time period
Solution Approach 1:
The patent applies preliminary action by obtaining the time division scheme for the next cruise monitoring period in advance and configuring control information before the adjustment period begins. This allows the network controller to proactively manage STA operations during upcoming adjustment periods, preventing user experience quality degradation before it occurs, rather than reacting after quality has already declined.
2Productivity
If no specific control policy is applied during adjustment periods, then the system operates without intervention, but network congestion occurs during these periods
Solution Approach 1:
The patent implements preliminary action by obtaining the time division scheme in advance that identifies adjustment periods, and configuring control information before these periods begin. This proactive approach allows the system to apply specific control policies during adjustment periods to prevent network congestion, rather than operating without intervention and reacting to congestion after it occurs.
Solution Approach 2:
The patent uses feedback mechanisms by evaluating QoS performance parameters (frame discard ratio, delay, jitter) and using this information to configure appropriate control information for adjustment periods. This closed-loop feedback ensures that control policies are tailored to actual network conditions while being applied proactively to prevent congestion.
3Ease of operation
If control information is not configured in advance, then the system operates with default settings, but effective control cannot be implemented in time
Solution Approach 1:
The patent applies preliminary action by obtaining the time division scheme for the next cruise monitoring period in advance and configuring control information before the adjustment period begins. This proactive configuration ensures that control information is ready and effective control can be implemented immediately when the adjustment period starts, eliminating delays associated with real-time decision-making.

AI summary
The invention provide a control method, including: obtaining a time division scheme of a STA in a next cruise monitoring period, where the next cruise monitoring period includes N adjustment periods and N monitoring periods determined by means of division according to N preset points; configuring control information according to the time division scheme, where the control information is for controlling an operating status of the STA in each adjustment period in the next cruise monitoring period; and sending the control information to the STA.
