Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capillary network gateways in cellular networks face high energy consumption and redundancy due to continuous operation, leading to increased energy expenditure and interference, especially when not all devices are needed for normal operations, which affects network performance.
Innovation Solution
A method for capillary network gateways to determine conditions for switching into a power-saving mode by measuring channel utilization and received field intensity, allowing them to associate with other gateways and disconnect from the base station, thereby reducing energy consumption and minimizing redundant resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capillary network gateways are continuously switched on to act as FFDs for the SRR network, then network coverage and reliability are improved, but energy consumption increases significantly
Solution Approach 1:
The patent implements dynamic operation modes for capillary network gateways, allowing them to switch between active FFD (Full Function Device) state and sleep state based on real-time network conditions. Gateways monitor parameters such as number of associated RFDs, traffic load, and signal strength to dynamically adjust their operational state, thereby reducing energy consumption while maintaining network coverage when needed
Solution Approach 2:
The patent employs periodic monitoring and evaluation mechanisms where gateways assess network conditions at regular intervals. This periodic action enables gateways to transition between active and sleep states in a controlled manner, ensuring that network coverage is maintained during high-traffic periods while energy consumption is reduced during low-activity periods
2Reliability
If capillary network gateways are deployed densely to accommodate worst-case traffic conditions, then network reliability is improved, but interference and contention level increase
Solution Approach 1:
The patent implements dynamic activation of gateways based on actual network demand. Instead of having all gateways continuously active, the system monitors traffic conditions and activates additional gateways only when necessary, thereby maintaining network reliability during peak loads while reducing interference during normal operations
Solution Approach 2:
The patent enables different gateways to have different operational states (active or sleep) based on local network conditions. This local quality approach allows the network to optimize performance by having only the necessary gateways active in specific geographic areas, reducing overall interference while maintaining reliability where needed
3Productivity
If capillary network gateways operate with high computational capabilities as FFDs, then network performance is improved, but device complexity and energy requirements increase
Solution Approach 1:
The patent implements dynamic capability adjustment where gateways operate with full FFD capabilities only when necessary for network operation. During periods when simpler operation suffices, gateways can reduce their computational activity and operational complexity, thereby improving network performance when needed while reducing device complexity and energy requirements during normal operations
