Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location determination mechanisms in mobile wireless communication stations, such as GPS and SSID-matching, face inefficiencies in terms of accuracy and resource usage, particularly in congested and open environments, where satellite signals may be obstructed or scarce.
Innovation Solution
A mobile station dynamically adjusts its operational mode based on turning rate and travel speed to select the most effective location determination mechanism, prioritizing SSID-matching in congested environments and satellite-based methods in open environments, thereby optimizing location determination efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If autonomous-GPS mechanism is used to determine location, then location accuracy is improved, but time consumption and system resource usage increase
Solution Approach 1:
The patent dynamically switches between autonomous-GPS and base station delay mechanisms based on environmental conditions (congested vs. open). In congested environments where satellite signals are obstructed, the system uses base station delay for faster response. In open environments, it switches to autonomous-GPS for higher accuracy, thus adapting the location determination approach to resolve the contradiction between accuracy and time consumption.
Solution Approach 2:
The system changes the operational parameter (location determination mechanism) based on environmental parameters (signal obstruction conditions). By monitoring whether the environment is congested or open, the system selects the appropriate mechanism, effectively resolving the trade-off between accuracy and time consumption through parameter adaptation.
2Measurement precision
If autonomous-GPS mechanism is used to determine location, then location accuracy is improved, but system resource consumption increases
Solution Approach 1:
The system dynamically selects the location determination mechanism based on environmental conditions. In congested environments, it uses the less resource-intensive base station delay mechanism. In open environments, it employs the more accurate but resource-consuming autonomous-GPS mechanism. This dynamic selection resolves the contradiction by matching resource consumption to actual accuracy requirements.
Solution Approach 2:
The system changes the operational mode (base station delay vs. autonomous-GPS) based on environmental parameters, thereby adjusting system resource consumption to match the actual location determination needs, resolving the contradiction between accuracy and resource usage.
3Loss of time
If base station delay mechanism is used to determine location, then time consumption is reduced, but location accuracy decreases
Solution Approach 1:
The system dynamically switches between base station delay and autonomous-GPS mechanisms based on environmental conditions. In congested environments where accuracy is less critical, it uses base station delay for fast response. In open environments where accuracy matters, it switches to autonomous-GPS, thus resolving the contradiction between speed and accuracy through adaptive selection.
Solution Approach 2:
The system changes the location determination mechanism parameter based on environmental conditions, selecting the appropriate mechanism (base station delay or autonomous-GPS) to match the required balance between response time and location accuracy for different scenarios.
4Loss of time
If SSID-matching mechanism is used to determine location, then time consumption is reduced and resource usage is minimized, but location accuracy decreases in open environments
Solution Approach 1:
The system dynamically selects between SSID-matching and satellite-based mechanisms based on environmental conditions. In congested environments with many SSIDs, it uses SSID-matching for fast, resource-efficient location determination. In open environments, it switches to satellite-based methods for higher accuracy, thus resolving the contradiction through adaptive mechanism selection.
Solution Approach 2:
The system changes the location determination approach (SSID-matching vs. satellite-based) based on environmental parameters, optimizing the balance between response time and location accuracy for different operational contexts.
5Measurement precision
If satellite-based location determination is used in congested environments, then location accuracy may be improved, but signal obstruction reduces reliability
Solution Approach 1:
The system dynamically switches between satellite-based and base station delay mechanisms based on environmental conditions. In congested environments where satellite signals are obstructed, it uses base station delay to ensure reliable location determination. In open environments, it employs satellite-based methods for higher accuracy, thus resolving the contradiction between accuracy and reliability through adaptive selection.
Solution Approach 2:
The system changes the location determination mechanism based on environmental parameters (signal obstruction conditions), selecting the appropriate method to maintain both accuracy and reliability for different operational scenarios.

AI summary
Disclosed herein is a method and mobile station that improves upon a mobile station's ability to determine its location. By a mobile station considering its extent of turning and/or its travel speed, the mobile station may set an operational mode such that the mobile station uses an appropriate location determining mechanism. In the event that the mobile station is turning at a fast rate and/or traveling at a slow speed, a reasonable conclusion is that the mobile station is in a congested environment, and therefore a first operational mode may be set. In the event that the mobile station is turning at a slow rate and/or traveling at fast speed, a reasonable conclusion is that the mobile station is in an open environment, and therefore a second operational mode may be set.
