Network Energy Saving QoS Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in balancing network energy savings with the need to maintain expected quality of service (QoS), especially as mobile data traffic increases and new use cases emerge.
Innovation Solution
The implementation of a Network Energy Saving (NES) class mechanism that incorporates QoS awareness, allowing User Equipment (UE) to report expected QoS and enabling network configuration of NES modes based on this information, thereby optimizing energy savings while ensuring performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If network energy saving mode is implemented, then energy consumption is reduced, but quality of service deteriorates
Solution Approach 1:
The patent implements dynamic NES configuration where the network can switch between different NES modes (e.g., full NES, partial NES, no NES) based on real-time QoS requirements. The system dynamically adjusts network behavior from energy-saving mode to performance-mode depending on user needs, resolving the contradiction between energy savings and service reliability.
Solution Approach 2:
The patent changes operational parameters of network elements by introducing NES configurations with different energy saving levels. By varying parameters such as transmission timing, resource allocation, and power levels, the system achieves different QoS outcomes while managing energy consumption, allowing flexible trade-off between energy savings and service quality.
2Loss of energy
If network energy saving configuration is applied, then energy consumption decreases, but user performance deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where user performance metrics are continuously monitored and fed back to the network controller. Based on this feedback, the system adjusts NES configurations to optimize the balance between energy savings and user performance, ensuring that energy reduction does not compromise service quality.
Solution Approach 2:
The patent segments the network into different operational modes (full NES mode, partial NES mode, no NES mode) that can be selectively applied to different network elements or user sessions. This segmentation allows the system to achieve energy savings in non-critical areas while maintaining performance in critical user services.
3Device complexity
If fixed NES mode is used, then implementation complexity is reduced, but adaptability to different QoS requirements deteriorates
Solution Approach 1:
The patent creates a universal NES framework that can handle multiple QoS requirements through a single unified mechanism. The system supports multiple NES modes and configurations within one framework, allowing it to adapt to diverse service requirements (e.g., voice, video, data) without requiring separate complex solutions for each service type.
Data Source
AI summary
Various aspects of the present disclosure relate to network energy saving (NES) correlated with quality of service (QoS). An apparatus, such as a user equipment (UE), receives, as a radio resource configuration from a network equipment (NE), an indication of at least one of a NES class or a NES configuration of the NES class. The UE is configured based on the NES configuration or the NES class. A NE determines the NES configuration based on an expected QoS as reported by one or more UE. The NE transmits, as a radio resource configuration to the one or more UE, the NES class or the NES configuration of the NES class.
