Gate Selection Using Terminal Position Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for authenticating and paying at gates, such as those in subways, face challenges in accurately determining gate passage, especially during peak times, and require close proximity between the user's card and the terminal, which can be inconvenient with baggage or gloves, and lacks non-contact solutions.
Innovation Solution
A method that calculates angles between a user terminal's location and pre-installed gates to determine if the user is entering or leaving a gate, selects the appropriate gate for authentication and payment, and performs these transactions at the correct time point, ensuring accurate and convenient service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC scheme is used for card tagging, then authentication and payment can be performed, but the card recognition distance is short requiring close proximity (5 cm) which causes inconvenience when user has baggage or wears gloves
Solution Approach 1:
The patent introduces a gate passage determination system that acts as an intermediary between the user and the authentication system. Instead of requiring direct card-to-terminal proximity, the system uses positioning information and angle calculation to determine gate passage, enabling remote authentication without physical contact or close proximity
2Measurement precision
If conventional card tagging method is used, then authentication can be performed, but it has difficulty in precisely determining gate passage during concentrated user periods
Solution Approach 1:
The system performs preliminary actions by continuously acquiring positioning information and pre-calculating angles between user terminal and gates before actual passage occurs. This allows the system to be ready for immediate authentication determination, improving both precision and efficiency during peak periods
Solution Approach 2:
The system implements feedback by continuously monitoring positioning information and angle changes to determine when a user has actually passed through a gate. This feedback mechanism ensures accurate passage determination even during concentrated user periods by dynamically adjusting detection based on real-time position data
3Productivity
If short-range wireless communication is used, then card tagging can be performed, but passage delay occurs when user needs to put down baggage or take off gloves
Solution Approach 1:
The system enables self-service by automatically determining gate passage based on the user's positioning information without requiring any manual action from the user. The angle calculation and passage determination are performed automatically, allowing users to pass through gates without stopping to interact with the system, thus maintaining high passage speed and convenience

AI summary
A method of a user terminal is provided. The method includes selecting two gates from among a plurality of gates, based on location information of the plurality of gates and location information of the user terminal, identifying whether the user terminal enters a radio access area on the basis of a value of an included angle between the two gates and the user terminal and, in response to the user terminal being entered the radio access area, selecting a first gate to perform radio access from among the two gates.
