Terminal Positioning Control for Stationary Reduced-Capacity Devices

Solution Overview

Problem

Existing terminal device positioning schemes continue to perform measurements and reporting even when the device is stationary, leading to unnecessary signaling overhead and energy consumption, particularly for reduced capacity devices.

Innovation Solution

Implement a stationarity detection mechanism in terminal devices to pause or stop positioning reference signal (PRS) measurements and reports, with configuration options via system information broadcast or dedicated signaling, and utilize a timer-based approach to manage periodic reporting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If positioning reference signal measurements and reports are continued for stationary terminal devices, then positioning accuracy is maintained, but energy consumption and signaling overhead increase

Engineering Contradiction:

Improvepositioning accuracyVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic positioning reporting by detecting terminal device stationarity and adapting reporting behavior accordingly. When a terminal device is detected to be stationary (based on position change thresholds and time durations), the system dynamically suspends positioning reference signal measurements and reports. This dynamic adaptation maintains positioning accuracy when needed while reducing energy consumption during stationary periods.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes positioning reporting parameters based on terminal device movement state. By monitoring position changes over time and comparing them against configured thresholds, the system adjusts the reporting parameter from continuous to suspended state. This parameter change enables the system to maintain positioning accuracy during movement while reducing energy consumption during stationary periods.

Solution Approach 1:

The patent implements a feedback mechanism that continuously monitors terminal device position changes and determines whether the device is stationary or moving. Based on this feedback, the system dynamically adjusts positioning reporting behavior. When movement is detected (position change exceeds threshold within time duration), reporting is resumed to maintain positioning tracking capability. This feedback-driven approach ensures positioning reliability is maintained when needed while enabling energy savings during stationary periods.
