DRX Configuration for User Equipment Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring discontinuous reception (DRX) in user equipment (UE) only consider quality of service (QoS) requirements from the core network, neglecting the unique features of individual UEs, which affects power saving performance and user experience.
Innovation Solution
Configuring DRX parameters based on UE-specific feature information, including service type, packet arrival interval, and data packet size, to tailor DRX settings to each UE's characteristics, thereby enhancing power saving and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If DRX parameters are configured based only on QoS requirements from core network, then system complexity is reduced and configuration is simplified, but power saving performance and user experience deteriorate due to neglecting individual UE features
Solution Approach 1:
The patent applies local quality by configuring DRX parameters individually for each UE based on their specific features (terminal type, service type, packet arrival interval, packet size) rather than using a uniform configuration for all UEs. This allows each UE to have optimized DRX settings tailored to its local characteristics, improving power saving performance while maintaining manageable system complexity through automated feature-based configuration.
Solution Approach 2:
The patent implements dynamics by making DRX parameters adaptive to changing UE features and service conditions. The base station dynamically determines DRX parameters based on current UE features, service types, and traffic patterns, allowing the system to adjust configurations in real-time rather than using static QoS-only parameters, thereby optimizing power consumption without excessive complexity.
2Ease of operation
If DRX parameters are configured based only on QoS requirements from core network, then configuration process is simplified, but user experience deteriorates due to lack of customization for different UE features
Solution Approach 1:
The patent applies self-service by enabling the base station to automatically determine and configure appropriate DRX parameters based on UE-reported features and service characteristics. The UE provides its feature information, and the base station autonomously selects optimal DRX parameters without requiring manual intervention or complex user input, thus maintaining ease of operation while achieving high adaptability to individual UE features.
Solution Approach 2:
The patent implements parameter changes by varying DRX parameters (such as DRX cycle length, on-duration, inactivity timer) based on specific UE features and service types. Different terminal types, service types, packet arrival intervals, and packet sizes trigger different parameter configurations, allowing the system to maintain simple configuration processes while achieving versatile adaptation to diverse UE characteristics through parameter adjustment.
3Adaptability or versatility
If frequent air interface signaling exchange occurs due to separated background data packets, then data transmission flexibility is improved, but system performance deteriorates
Solution Approach 1:
The patent applies periodic action by configuring DRX parameters that establish regular monitoring cycles for UEs handling background data traffic. Instead of requiring continuous or frequent signaling exchanges for each separated data packet, the system uses periodic DRX cycles to monitor control channels and data, reducing signaling overhead while maintaining the ability to handle flexible data transmission patterns characteristic of background services.
Solution Approach 2:
The patent implements continuity of useful action by ensuring that DRX configurations maintain continuous data transmission capability for background services while reducing unnecessary signaling. The periodic monitoring cycles ensure that data transmission flexibility is preserved throughout the DRX period, allowing separated background data packets to be transmitted efficiently without frequent interruptions or excessive signaling exchanges that would degrade system performance.
