Preferential Queuing for Wireless Data in Doze State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication apparatuses lack power-saving mechanisms, leading to increased power consumption during data transmission, which can cause delays and affect network performance.
Innovation Solution
Implementing a wireless communication program that switches between awake and doze states, using separate queues for preferential and non-preferential data transmission, ensuring that critical data is transmitted first and balancing data transmission to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information processing apparatus continuously operates in an awake state to ensure smooth data transmission, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The wireless communication apparatus dynamically switches between awake and doze states based on the priority of data to be transmitted. High-priority data is transmitted during awake states, while low-priority data transmission is deferred, allowing the system to enter doze states and reduce power consumption while maintaining essential communication reliability.
Solution Approach 2:
The patent segments data into high-priority and low-priority categories, and correspondingly segments transmission opportunities into awake states (for high-priority data) and doze states (for power saving). This segmentation allows the system to maintain reliability for critical communications while reducing overall power consumption by not continuously operating at full capacity.
2Use of energy by moving object
If the information processing apparatus enters a doze state to reduce power consumption, then power consumption is reduced, but data transmission may be delayed
Solution Approach 1:
The system performs preliminary classification of data into high-priority and low-priority queues before entering doze states. High-priority data is prepared and queued for immediate transmission upon waking, ensuring that critical data experiences minimal delay even when the system alternates between awake and doze states. Low-priority data is deferred to subsequent transmission opportunities.
3Productivity
If separate queues are used for preferential and non-preferential data transmission, then data transmission priority is improved, but device complexity increases
Solution Approach 1:
The patent implements segmentation by dividing the data queue into two separate queues: a high-priority queue for preferential data and a low-priority queue for non-preferential data. This segmentation enables the system to efficiently manage transmission priorities by processing high-priority data first, improving overall data transmission efficiency while keeping the complexity manageable through a clear, binary classification system.

AI summary
A game apparatus repeatedly switches between a doze state in which a wireless communication function is restricted, and an awake state. The game apparatus stores unicast data and broadcast data acquired in the awake state, in a normal queue, and transmits the pieces of data to air in acquisition order. On the other hand, in the doze state, the game apparatus stores acquired broadcast data in a preferential transmission queue, and stores acquired unicast data in the normal queue. Thereafter, when the game apparatus becomes the awake state again, the game apparatus transmits the broadcast data stored in the preferential transmission queue in preference to the unicast data stored in the normal queue.
