Radio Access Network Power Management via Traffic Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing power consumption in radio access networks, such as switching off and on resources based on traffic intensity, result in latency periods and electromagnetic pollution issues, and do not effectively minimize power consumption without affecting service availability.
Innovation Solution
A method that defines clusters of radio resource units, calculates optimum traffic throughputs to optimize power consumption, and distributes traffic among these units to minimize power usage without service disruptions, using power models and traffic steering mechanisms to ensure continuous service and reduced electromagnetic pollution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If resources are switched on and off to reduce power consumption, then power consumption is reduced, but service availability deteriorates due to latency and temporary unavailability
Solution Approach 1:
The patent implements dynamic traffic distribution among radio resource units within clusters, allowing the system to adaptively adjust resource allocation based on real-time traffic conditions. This dynamic approach enables continuous service availability while optimizing power consumption by directing traffic away from units in low-power states without requiring switching operations that cause latency.
2Use of energy by moving object
If resources are switched on and off to reduce power consumption, then power consumption is reduced, but electromagnetic pollution worsens due to reconfiguration activities
Solution Approach 1:
The patent pre-configures clusters of radio resource units with predetermined traffic distribution strategies and power management policies. By establishing these configurations in advance, the system can respond to traffic conditions without performing real-time switching operations that generate electromagnetic pollution, thus reducing harmful emissions while maintaining power efficiency.
3Use of energy by moving object
If traffic is distributed among radio resource units to optimize power consumption, then power consumption is reduced, but system complexity increases due to cluster management
Solution Approach 1:
The patent divides the radio access network into multiple clusters of radio resource units, where each cluster is managed semi-independently. This segmentation reduces overall system complexity by localizing management decisions within clusters rather than requiring centralized control of the entire network, while still achieving power consumption optimization through coordinated traffic distribution within each cluster.

AI summary
A method for managing power consumption of a radio access network. The method includes: defining a cluster including at least two radio resource units of the radio access network; defining a parameter indicative of a performance of the cluster and of a power consumption of the cluster, the parameter being expressed as a function of traffic throughputs carried by the radio resource units of the cluster; calculating optimum traffic throughputs as values of the traffic throughputs carried by the radio resource units of the cluster which optimize the parameter; and distributing traffic amongst the radio resource units of the cluster such that the radio resource units of the cluster carry the calculated optimum traffic throughputs.
