Throughput Limiter for Mobile Network Energy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to reduce power consumption in mobile communication networks to minimize costs and environmental impact, while existing technologies have not effectively addressed this challenge.
Innovation Solution
The method involves forwarding data traffic based on quality of service classes with an energy control attribute, using a throughput limiter to set a maximum data throughput limit, which can be a fraction of total throughput or absolute value, to control power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data throughput is increased to improve network performance, then productivity is improved, but use of energy worsens
Solution Approach 1:
The patent implements dynamic energy control by allowing the throughput limiter to adjust data throughput limits based on varying network conditions, traffic patterns, and energy availability. The system can dynamically modify the maximum throughput for different QoS classes rather than using fixed limits, enabling adaptive optimization between performance and energy consumption.
Solution Approach 2:
The patent changes the parameter of data throughput from an unlimited or fixed value to a dynamically controllable parameter with configurable maximum limits. By introducing energy control attributes and throughput limits as adjustable parameters, the system can optimize the balance between data throughput and power consumption based on specific operational requirements.
2Use of energy by moving object
If power consumption is reduced to save costs and environmental impact, then use of energy is improved, but productivity worsens
Solution Approach 1:
The patent segments the network traffic into different QoS classes and applies differentiated throughput limits to each class. This allows the system to reduce overall power consumption by limiting throughput for less critical traffic classes while maintaining adequate performance for high-priority classes, achieving energy savings without uniformly degrading all network services.
Solution Approach 2:
The patent applies local quality control by assigning different energy control attributes and throughput limits to different QoS classes based on their specific requirements. Each traffic class receives a customized throughput limit tailored to its priority and sensitivity to delays, enabling precise local optimization of the energy-performance tradeoff rather than uniform control across all traffic.
3Use of energy by moving object
If throughput limiting is implemented to control energy usage, then use of energy is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal energy control mechanism that can be applied across multiple QoS classes and network conditions through a single throughput limiter framework. The same basic mechanism handles diverse traffic types by simply configuring different parameters (throughput limits per QoS class), avoiding the need for separate complex control systems for each traffic type and reducing overall system complexity.
Data Source
AI summary
In a mobile communication network, data traffic of a certain quality of service class is forwarded in accordance with a traffic forwarding policy associated with this quality of service class, e.g. by establishing dedicated bearers (52, 54). For implementing energy control, an energy control attribute is assigned to the quality of service class. On the basis of the energy control attribute, a data throughput for forwarding the data traffic is limited to a maximum limit. This may be accomplished by using a throughput limiter (150, 250) in one or more nodes (100, 110, 120, 200) participating in the transport of the data traffic.
