User Terminal Emulation Server DRX Configuration for Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user terminal technologies face challenges in optimizing power consumption and responsiveness of input/output (I/O) user devices to downlink radio communications, particularly when not in use, due to limitations in predicting user proximity and managing discontinuous reception (DRX) settings effectively.
Innovation Solution
A user terminal emulation server predicts the likelihood of user proximity to I/O devices and configures DRX settings to optimize power consumption and responsiveness by adjusting the frequency of downlink reception opportunities based on predicted user presence, allowing devices to quickly transition into active modes when the user approaches.

Engineering Contradiction Analysis
1Speed
If DRX settings are configured to frequently monitor downlink communications, then responsiveness to user communication needs is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic DRX configuration where the network entity adjusts DRX parameters (such as drx-OnDuration, drx-SlotOffset, drx-InactivityTimer) based on real-time user proximity detection. When a user approaches an I/O device, the system transitions from extended DRX (longer sleep cycles) to ultra-compact DRX (shorter monitoring intervals), optimizing the balance between power savings and communication responsiveness without manual intervention.
Solution Approach 2:
The system employs feedback loops where proximity detection results trigger DRX parameter adjustments. The network entity continuously monitors user proximity status and dynamically modifies DRX configurations accordingly, creating a closed-loop control system that adapts to changing conditions and optimizes power-consumption versus responsiveness trade-offs in real-time.
2Reliability
If I/O user devices remain in active state to ensure immediate communication service, then service availability is improved, but battery life decreases
Solution Approach 1:
The patent implements preliminary action by detecting user proximity in advance and proactively adjusting DRX settings before the user actually needs to use the device. When proximity is detected, the system pre-configures ultra-compact DRX parameters, ensuring the device is prepared for immediate communication service while minimizing power consumption during the transition period, rather than maintaining continuous active state.
Solution Approach 2:
The system dynamically changes DRX parameters (drx-OnDuration, drx-SlotOffset, drx-InactivityTimer, etc.) based on user proximity status. During extended DRX mode, longer sleep cycles conserve battery life, while during ultra-compact DRX mode, shorter monitoring intervals ensure service availability. This parameter adaptation allows the system to optimize the reliability-duration trade-off according to actual usage conditions.
3Measurement precision
If processing resources are allocated to continuously monitor for user presence, then detection accuracy is improved, but processing and memory resource usage increases
Solution Approach 1:
The patent applies partial action by implementing tiered monitoring strategies. Instead of continuously allocating maximum processing resources, the system uses extended DRX with longer intervals during low-activity periods, reducing processing and memory usage. When proximity detection triggers communication events, the system temporarily increases monitoring intensity with ultra-compact DRX, achieving accurate detection only when necessary rather than maintaining constant high-resource allocation.
4Reliability
If air interface signaling is increased to maintain constant connection readiness, then communication reliability is improved, but network overhead increases
Solution Approach 1:
The patent implements periodic action through DRX cycles, where the I/O device monitors downlink communications at regular intervals rather than continuously. During extended DRX, monitoring intervals are longer, reducing air interface signaling overhead. When ultra-compact DRX is activated due to user proximity, monitoring frequency increases to maintain communication reliability. This periodic monitoring approach balances reliability requirements with network overhead reduction by adapting the period length based on actual conditions.
