Radio Access Mode Selection Based on Expected Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern communication devices face challenges in efficiently and flexibly selecting radio access technologies due to varying factors such as power consumption, communication costs, and network conditions, leading to suboptimal performance and increased energy expenditure.
Innovation Solution
A communication device is equipped with a determiner to assess expected power consumption for each radio access mode and a controller to select the most suitable mode based on these determinations, as well as a detector and controller to manage switching between radio access technologies with a mandatory waiting period to prevent frequent switching and optimize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device frequently switches between different radio access technologies to optimize communication quality, then communication quality is improved, but power consumption increases and system stability deteriorates
Solution Approach 1:
The system performs preliminary evaluation of multiple radio access modes before making a selection decision. The determiner assesses expected power consumption for each mode in advance, and the controller selects the optimal mode based on this pre-evaluation, avoiding frequent switching and reducing power consumption while maintaining communication quality.
Solution Approach 2:
The radio access mode selection is made dynamic and adaptive based on current communication conditions. The system continuously monitors communication quality requirements and adjusts the selected radio access mode accordingly, optimizing the balance between communication quality and power consumption rather than using a fixed selection strategy.
2Adaptability or versatility
If the communication device switches radio access modes frequently to adapt to changing network conditions, then adaptability is improved, but system stability deteriorates due to unnecessary switching
Solution Approach 1:
The determiner evaluates expected power consumption and communication quality for each radio access mode in advance before the controller makes a switching decision. This preliminary assessment ensures that switching only occurs when genuinely beneficial, improving adaptability while preventing unnecessary switches that would harm system stability.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller monitors communication quality and power consumption outcomes, and uses this information to refine future mode selection decisions. This feedback loop enables the system to adapt to changing network conditions while learning from past switching decisions to maintain stability.
3Measurement precision
If the communication device evaluates multiple radio access modes in detail to ensure optimal selection, then selection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts and focuses on the critical evaluation parameter of expected power consumption for each radio access mode. By concentrating on this key factor rather than evaluating all possible parameters in detail, the system achieves sufficiently accurate mode selection while avoiding excessive complexity in the evaluation process.
