Wireless Location Reporting via Asynchronous Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 3GPP LTE networks, there is a discrepancy between the time of acquiring measurement results and location information, which hinders network performance optimization and accuracy, as the network cannot always obtain relevant location information simultaneously with measurement results, leading to suboptimal service quality.
Innovation Solution
A method where user equipment transmits measurement results at specific times, acquiring and reporting location information based on initial and subsequent location estimations, using interpolation parameters to determine the validity and timing of location information transmission, ensuring correlation with measurement results, even if location information is acquired after the measurement result is reported.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If location information is acquired after measurement result is reported, then the network can obtain location information, but the correlation between location information and measurement result deteriorates due to time discrepancy
Solution Approach 1:
The user equipment performs preliminary action by acquiring location information before the measurement result reporting, or at the same time, to ensure that the location information is available and correlated with the measurement result. This eliminates the time discrepancy problem by preparing the location data in advance or simultaneously with the measurement.
2Measurement precision
If location information is acquired simultaneously with measurement result, then correlation accuracy is improved, but the device complexity increases due to additional timing coordination requirements
Solution Approach 1:
The system introduces dynamic flexibility by allowing the user equipment to acquire location information at different times relative to measurement result reporting, rather than requiring strict simultaneous acquisition. The network dynamically processes location information based on its acquisition time, maintaining correlation accuracy without rigid timing constraints.
3Adaptability or versatility
If the network processes location information acquired at different times, then the system flexibility is improved, but the processing complexity increases
Solution Approach 1:
The network employs feedback mechanisms to track and correlate measurement results with location information acquired at different times. By maintaining temporal context and using feedback loops to match corresponding data elements, the network processes asynchronous information streams while preserving their correlation, thus achieving flexibility without excessive complexity.
