Triggered Location Service Dynamic Positioning Method Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional triggered location request services face issues when a target terminal moves to a different electromagnetic environment, leading to positioning method failures and service termination due to inability to continuously calculate accurate location information over extended periods.
Innovation Solution
A location service system that prioritizes and switches between available positioning methods based on the target terminal's current electromagnetic environment, selecting the highest priority method capable of providing accurate location data, such as GPS or TDOA, to ensure continuous service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single positioning method is determined at the start of triggered location request service, then the service can be initiated with clear positioning instructions, but the service cannot continue when the terminal moves to an environment where the determined positioning method is unavailable
Solution Approach 1:
The patent implements dynamic positioning method selection by enabling the target terminal to periodically report available positioning methods to the location server during service execution. The location server then dynamically determines and updates the positioning method based on current environmental conditions, allowing the system to adapt from a static initial selection to a flexible, environment-responsive approach that maintains service continuity.
Solution Approach 2:
The patent establishes a feedback mechanism where the target terminal continuously monitors its electromagnetic environment and reports available positioning methods back to the location server. This feedback loop enables the system to detect changes in environmental conditions and trigger re-evaluation of the positioning method, ensuring the service adapts to new conditions rather than failing when the initially selected method becomes unavailable.
2Adaptability or versatility
If the system supports multiple positioning methods with priority ordering, then it can adapt to different electromagnetic environments, but the complexity of selecting and managing positioning methods increases
Solution Approach 1:
The patent applies preliminary action by having the target terminal pre-identify and report all available positioning methods to the location server at the start of the service, along with establishing a priority order. This preliminary setup creates a ready-to-use ranked list of positioning methods that can be quickly selected based on environmental conditions without requiring complex real-time analysis, thereby reducing operational complexity while maintaining adaptability.
Solution Approach 2:
The patent manages complexity by changing the parameter of positioning method selection from a complex real-time decision-making process to a simpler parameter-based selection. The system uses the priority order parameter established in advance and the availability status parameter reported periodically to determine which positioning method to use, converting a complex multi-factor decision into a straightforward parameter comparison that reduces computational and managerial complexity.

AI summary
Disclosed are a location service providing system and a method for providing a triggered location request service. An H-SLP sets a priority order of a plurality of positioning methods which a target terminal supports according to a set priority order set condition and transmits priority order information according to respective positioning methods to the target terminal. Further, the target terminal may receive information about the positioning methods including the priority order and select a positioning method having the highest priority order among the positioning methods, which can be used in its current electric wave environment. Moreover, the H-SLP and the target terminal may calculate a location of the target terminal according to a positioning method that the target terminal has selected. Accordingly, although it is difficult to calculate the location of the target terminal according to the positioning method that the target terminal has selected, a location service of the target terminal can be continuously provided.
