Dynamic Location Reporting Adjustment for Wireless UE Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face unnecessary power consumption when regularly reporting location information, especially when stationary or moving slowly, which reduces battery life.
Innovation Solution
A method and apparatus for a user equipment (UE) to determine its properties and adjust location information reporting parameters, such as frequency and accuracy, based on its state, using techniques like satellite positioning systems, sensor data, and network feedback to minimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE determines and reports location information regularly, then location information availability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of location reporting parameters based on UE properties. The system transitions from static regular reporting to dynamic reporting where parameters such as reporting frequency and accuracy are adjusted according to UE speed, battery status, and movement patterns. This resolves the contradiction by making the system adaptive rather than fixed.
Solution Approach 2:
The patent changes multiple parameters including reporting frequency, accuracy requirements, and triggering conditions based on UE state. When UE is stationary or moving slowly, reporting frequency is reduced and accuracy requirements are relaxed. When UE is moving quickly, reporting frequency increases. This parameter adjustment strategy resolves the contradiction between information availability and power consumption.
2Measurement precision
If a UE reports location information with high accuracy, then location precision is improved, but power consumption increases
Solution Approach 1:
The patent applies different accuracy requirements to different UE states and locations. Instead of uniform high accuracy reporting, the system adjusts accuracy levels locally based on UE properties such as speed, service type, and geographic location. This resolves the contradiction by applying appropriate accuracy only where needed.
Solution Approach 2:
The patent implements partial action by reporting location information at reduced accuracy when high precision is not required. The system determines minimum necessary accuracy based on service requirements and UE state, reporting with that level rather than maximum available accuracy. This reduces power consumption while maintaining sufficient location information quality.
3Loss of time
If a UE reports location information frequently, then location information freshness is improved, but battery life is reduced
Solution Approach 1:
The patent implements periodic location reporting with variable periods based on UE state. Instead of continuous or fixed-period reporting, the system adjusts the reporting period dynamically. When UE is stationary, periods are extended; when UE is moving, periods are shortened. This resolves the contradiction between information freshness and battery life.
Solution Approach 2:
The patent uses feedback mechanisms where the network and UE monitor UE movement patterns, service requirements, and battery status to adjust reporting frequency. The system receives feedback about UE state changes and adapts reporting frequency accordingly, maintaining information freshness while conserving battery life through intelligent feedback-driven adjustments.
