Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current positioning methods in wireless networks are inefficient in dynamic environments, as they rely on fixed techniques and do not adapt to changing conditions, leading to varying accuracy and availability of location information.
Innovation Solution
A method where a location server in a wireless network adaptively selects positioning techniques for a user equipment (UE) based on parameter information, allowing the UE to dynamically choose the most suitable positioning method for accurate location determination, minimizing excessive signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed positioning methods are used in current wireless networks, then the positioning system is simple to implement, but the location information accuracy deteriorates in dynamic environments
Solution Approach 1:
The patent implements dynamic positioning method selection where the UE adapts between different positioning techniques (GNSS, Wi-Fi, cellular) based on real-time environmental conditions and service requirements, transforming the static positioning system into a dynamic one that optimizes accuracy for varying scenarios
Solution Approach 2:
The system changes positioning parameters dynamically by selecting different positioning methods based on environmental parameters (indoor/outdoor, urban/rural) and service parameters (accuracy requirements, latency constraints), allowing the same system to achieve high accuracy across diverse conditions without increasing fundamental system complexity
2Reliability
If multiple positioning methods are always used to ensure accuracy, then location information availability improves, but energy consumption in the UE increases
Solution Approach 1:
The UE dynamically activates or deactivates specific positioning methods based on current environmental conditions and service requirements, ensuring high availability when needed while conserving energy during periods when certain methods are unnecessary or unavailable
Solution Approach 2:
The UE autonomously performs adaptive selection of positioning methods based on local environmental assessments and received service requirements, making real-time decisions about which positioning techniques to employ without requiring continuous network control, thereby optimizing energy usage while maintaining reliability
3Measurement precision
If the network controls all positioning decisions centrally, then positioning performance can be optimized, but signaling overhead between UE and network increases
Solution Approach 1:
The network provides positioning policy parameters and service requirement information as intermediary guidance to the UE, which then autonomously selects appropriate positioning methods based on these parameters, reducing the need for extensive direct network control signaling while maintaining optimized positioning performance
Solution Approach 2:
The UE autonomously performs positioning method selection based on received policy parameters and local environmental conditions, eliminating the need for the network to send detailed control signals for each positioning decision, thereby reducing signaling overhead while maintaining centralized optimization capabilities through policy guidance
4Measurement precision
If adaptive positioning method selection is implemented, then location information accuracy improves in dynamic environments, but the complexity of the positioning system increases
Solution Approach 1:
The UE implements dynamic selection among a finite set of positioning methods based on environmental conditions and service requirements, achieving high accuracy through adaptability while managing complexity by using standardized protocols and predefined positioning techniques rather than requiring complex custom algorithms
