Solution Overview
Problem
Current Bluetooth-enabled access control points are limited in the number of simultaneous communication sessions they can establish due to resource consumption and overhead in the pairing process, leading to performance issues and access decision latency, especially in crowded areas with multiple devices.
Innovation Solution
A Bluetooth-enabled access control system that uses an Access Point Gateway with multiple Access Control Modules to establish connectionless interactions with wireless presence indicating devices, prioritizing high-priority devices and balancing resource loads through a Load Balancer and Biometric Verification Module, allowing seamless handoffs and efficient access control decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth pairing process is used to establish communication sessions, then authentication information can be obtained, but resource consumption increases and the number of simultaneous connections is limited
Solution Approach 1:
The patent extracts the authentication function from the full Bluetooth pairing process. Instead of requiring complete pairing, the system uses only the connectionless advertising phase to obtain authentication information, eliminating the resource-intensive connection establishment and data exchange phases while maintaining security.
Solution Approach 2:
The system performs authentication preliminarily by extracting authentication information during the advertising phase before full connection is established. This preliminary authentication allows the system to pre-screen devices and avoid establishing full connections with unauthorized devices, reducing overall resource consumption.
2Adaptability or versatility
If multiple Bluetooth devices establish communication sessions with access control point, then more devices can be served, but performance is lost and access decision latency increases
Solution Approach 1:
The patent segments the access control system into multiple access control modules (ACMs) that can independently process authentication requests. This segmentation allows parallel processing of multiple devices simultaneously, maintaining high service capacity while preventing any single module from becoming a performance bottleneck.
Solution Approach 2:
The system performs partial authentication by extracting only the necessary authentication information from advertising packets rather than requiring complete device pairing. This partial action reduces the computational overhead per device while maintaining security, allowing faster processing of multiple devices.
3Quantity of substance
If access control point capacity is occupied by lower priority devices, then more devices can connect, but high priority devices cannot be granted access
Solution Approach 1:
The patent implements local quality by assigning different priority levels to different devices based on their characteristics or authorization. The load balancer selectively applies different connection policies to different devices, allowing high-priority devices to receive preferential treatment in terms of connection establishment and resource allocation, while still accommodating multiple devices overall.
4Measurement precision
If bi-directional communication session is established for user identification, then accurate authentication can be performed, but resource consumption increases
Solution Approach 1:
The patent extracts the essential authentication data from the advertising packets transmitted by Bluetooth devices. By parsing and analyzing this connectionless data, the system obtains sufficient information for authentication decisions without requiring the establishment of bidirectional communication sessions, thereby reducing communication overhead while maintaining accuracy.
