Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location-based services face inaccuracies and delays in determining whether a mobile terminal belongs to a target area, leading to unacceptable false positives or false negatives, which can impact various services differently in terms of accuracy and timing requirements.
Innovation Solution
A method that adjusts determination parameters based on service specifications, including probabilities of incorrect detection and area size ratios, using a mathematical model to optimize the accuracy of determining terminal location within a communications network, allowing for customizable accuracy settings for different services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location methods (GPS, E-OTD, OTDOA) or localised triggers are used to determine whether a terminal belongs to a target area, then the service can be provided based on area membership, but inaccuracies and delays occur leading to false positives or false negatives
Solution Approach 1:
The patent changes the determination parameters dynamically based on service specifications. Different services have different tolerances for false positives and false negatives, so the system adjusts parameters such as probability thresholds and area size ratios according to the specific service requirements, thereby optimizing the balance between reliability and measurement precision for each service type
Solution Approach 2:
The system transitions from static area determination to dynamic parameter adjustment. The determination parameters are not fixed but are adapted in real-time based on the service type and its specific accuracy requirements, allowing the system to optimize performance for different applications such as advertising vs. safety services
2Adaptability or versatility
If the determination parameters are made adjustable based on service specifications, then the accuracy can be optimized for different services, but the system complexity increases
Solution Approach 1:
The patent applies different determination parameters to different services based on their local requirements. Each service type (advertising, safety, billing) has its own optimized parameters for false positive and false negative tolerance, allowing customized accuracy settings without requiring complete system redesign for each service
Solution Approach 2:
The system pre-defines service specifications and determination parameters for different service types. Before actual operation, the appropriate parameters are selected and configured based on the service type, eliminating the need for complex real-time calculations and reducing operational complexity

AI summary
The system allows determining whether at least one terminal belongs to a target space in a communications network in order to provide a set of services linked to the fact that the terminal belongs or does not belong to the above target space. The belonging is determined depending on at least one determination parameter. The services are associated with, preferably through a model, respective service specifications indicating the allowable error margin in determining whether the terminal belongs or does not belong to the target space. The determination parameters are changed depending on the above service specifications.
