Variable-Positioning Reporting Method for Wireless Terminal Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in LTE networks, the continuous positioning function in user equipment leads to significant power consumption and inefficient network optimization, as it is activated regardless of necessity, affecting network performance and battery life.
Innovation Solution
A reporting method that configures a variable positioning duration time for user equipment, allowing positioning to be activated only when necessary, with a positioning activation condition evaluation and a timer to manage this activation, ensuring accurate location information is collected during specified intervals and minimizing unnecessary power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous positioning function is activated in user equipment, then accurate location information can be acquired, but power consumption increases significantly
Solution Approach 1:
The patent implements periodic positioning by configuring a positioning duration timer that activates positioning only during specific time intervals rather than continuously. The network configures a positioning duration time parameter, and the UE activates positioning function only when the timer is running, periodically deactivating it to save power while still acquiring location information at regular intervals for network optimization purposes
2Reliability
If positioning is activated continuously for network optimization, then location information is always available, but battery life is reduced
Solution Approach 1:
The patent makes the positioning activation dynamic by introducing a timer-based mechanism that adapts the positioning duration based on network configuration. The positioning function is activated only when the positioning duration timer is running, allowing the system to dynamically adjust between active positioning and power-saving mode based on network optimization needs, thereby extending battery life while maintaining network optimization effectiveness
3Productivity
If positioning activation condition is set to always satisfy, then location information is frequently collected, but unnecessary power consumption occurs
Solution Approach 1:
The patent implements feedback control through the positioning activation condition evaluation mechanism. The UE continuously evaluates whether the positioning activation condition is satisfied before activating positioning, and the network can configure conditions based on measurement reports, location accuracy requirements, and network state. This feedback loop ensures positioning is activated only when truly necessary, avoiding unnecessary power consumption while maintaining adequate location information collection frequency
