Mobile Payment Terminal WLAN Access Point Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for collecting access point information in WLAN-based location measurement systems are inadequate, particularly for areas inaccessible to scanning vehicles, such as indoors, leading to reduced accuracy and service quality due to incomplete data sets.
Innovation Solution
A method and system that utilizes a mobile communication terminal with a mobile card payment function to collect access point information by transmitting a control signal during a payment transaction, allowing for the gathering of information from access points within difficult-to-scan areas and storing this data for improved location measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a scanning car is used to collect access point information, then information can be collected along road paths, but information from inaccessible areas such as inside buildings cannot be collected
Solution Approach 1:
The mobile terminal is designed to serve multiple functions: it acts as both a payment device for mobile card transactions and as a data collection device for gathering access point information. This multi-functionality allows the system to collect information from various locations including inaccessible indoor areas without requiring separate dedicated collection devices or methods.
Solution Approach 2:
The mobile terminal automatically collects access point information during normal payment operations without requiring separate manual intervention. The terminal utilizes its existing wireless communication capabilities to autonomously detect and report access point data, transforming a routine payment device into an automatic information gathering node.
2Measurement precision
If access point information is collected only along road paths, then collection is simple, but location measurement accuracy deteriorates due to incomplete data
Solution Approach 1:
The mobile terminal autonomously performs access point information collection during its normal operation without requiring complex external collection infrastructure. The terminal's existing wireless communication module automatically detects access points and transmits information, achieving comprehensive data collection through the device's inherent capabilities rather than through added system complexity.
Solution Approach 2:
The payment system is enhanced to simultaneously perform information collection functions. The mobile card payment terminal not only processes transactions but also gathers location data, eliminating the need for separate dedicated collection systems and reducing overall system complexity while improving measurement accuracy.
3Measurement precision
If the number of access point information items in the database is increased, then location measurement accuracy improves, but data collection difficulty increases for inaccessible areas
Solution Approach 1:
The mobile terminal automatically collects and transmits access point information during routine payment operations. This self-service mechanism eliminates the need for manual data collection efforts and makes it feasible to accumulate comprehensive information from diverse locations including inaccessible indoor areas, thereby improving database completeness and measurement accuracy.
Solution Approach 2:
The payment terminal is transformed into a dual-purpose device that both processes transactions and collects location data. This multi-functionality enables the system to expand database coverage to include previously inaccessible areas without requiring separate collection operations, making comprehensive data gathering more practical and easier to implement.
