Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods fail to effectively manage quality of service (QoS) profiles in complex communication scenarios, particularly in terms of power consumption and energy efficiency, leading to potential overheating and reduced standby time of terminals.
Innovation Solution
A communication method and apparatus that considers power consumption parameters to determine a target QoS profile, allowing terminals to adjust service parameters such as task split points, bit rates, and resolution in response to network status changes, thereby optimizing power usage and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional QoS mapping methods are used, then data transmission quality is ensured, but power consumption increases and terminal overheating occurs
Solution Approach 1:
The patent implements dynamic QoS profile selection by allowing the terminal to switch between multiple candidate QoS profiles based on real-time power consumption conditions. The network element provides multiple QoS profiles with different power consumption characteristics, and the terminal dynamically selects the appropriate profile according to its current power state, transforming the static QoS mapping into a dynamic adaptive mechanism that balances transmission quality and power consumption.
Solution Approach 2:
The patent changes the parameter set used for QoS profile selection by incorporating power consumption parameters into the QoS profile configuration. Instead of using only traditional QoS parameters (bit rate, delay, jitter), the system now considers power consumption as a selectable parameter, allowing terminals to adjust their operating parameters based on power availability and requirements.
2Speed
If higher data rates are used, then transmission speed improves, but terminal power consumption increases and standby time decreases
Solution Approach 1:
The system dynamically adjusts the data rate by selecting different QoS profiles based on terminal power conditions. When the terminal has sufficient power, higher data rate profiles can be used; when power is constrained, the system automatically selects lower data rate profiles that conserve battery life, extending standby time while maintaining acceptable transmission speed.
Solution Approach 2:
The patent allows partial power utilization by providing multiple QoS profiles with varying power consumption levels. The terminal doesn't need to operate at maximum power capacity continuously; instead, it can use only the necessary power level required for its current communication needs, extending battery life without significantly impacting transmission performance.
3Adaptability or versatility
If multiple candidate QoS profiles are provided, then adaptability to power conditions improves, but network complexity increases
Solution Approach 1:
The patent segments the QoS configuration into multiple discrete profiles, each with specific power consumption and performance characteristics. Instead of a single complex QoS configuration, the system divides the parameter space into separate, manageable profiles that can be independently selected and applied, making the complexity more organized and easier to manage.
Solution Approach 2:
The network element acts as an intermediary that pre-configures and provides multiple QoS profiles to the terminal. This intermediary approach shifts the complexity management to the network side, where profiles are prepared and selected, rather than requiring the terminal to handle complex real-time optimization decisions.
4Ease of operation
If QoS profiles are dynamically adjusted, then user experience improves, but signaling overhead increases
Solution Approach 1:
The patent implements preliminary action by having the network element pre-configure and provide multiple QoS profiles to the terminal in advance. The terminal stores these profiles locally and can switch between them without requiring continuous complex signaling exchanges, reducing overhead while maintaining dynamic adaptability for better user experience.
