BLE Advertising Packet Authentication for Connectionless Asset Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power transfer systems face limitations in fast and reliable data transmission for asset tracking and authentication, particularly in connectionless methods, and require efficient resumption of authentication procedures for wireless power transmission devices.
Innovation Solution
A method and apparatus for connectionless asset tracking in wireless communication systems using Bluetooth Low Energy (BLE) for out-of-band communication, involving the reception and decryption of advertising packets with specific AD structures, and a device comprising a transceiver, memory, and processor for determining location and resuming authentication procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If in-band communication is used for wireless power transfer, then power transfer functionality is supported, but data transmission speed and capacity are limited
Solution Approach 1:
The patent introduces BLE (Bluetooth Low Energy) as an intermediary out-of-band communication channel to handle data transmission tasks, while the in-band channel continues to handle power transfer. This mediator approach allows high-speed data exchange through BLE without compromising the reliability of power transfer through the dedicated in-band channel.
2Adaptability or versatility
If connectionless asset tracking is implemented, then location tracking capability is provided, but authentication trust cannot be ensured
Solution Approach 1:
The patent implements preliminary authentication actions before enabling connectionless asset tracking. The authentication procedure establishes trust credentials in advance, allowing the system to verify the authenticity of location information broadcasts even when no continuous connection exists between the tracked device and the tracking system.
3Productivity
If authentication procedure is stopped for wireless power transmission device, then power transfer can resume quickly, but authentication security may be compromised
Solution Approach 1:
The patent performs authentication procedures in advance before power transfer begins, establishing security credentials beforehand. This preliminary authentication allows the system to quickly resume power transfer after interruptions without repeating the full authentication sequence, maintaining both security and efficiency.

AI summary
The present disclosure relates to a method, an apparatus, and a computer program for authenticating a connectionless asset tracking service in a Wireless communication system, and a recording medium for the computer program. The method for authenticating a connectionless asset tracking service comprises the steps in which a first device: receives an advertising packet from a second device; determines whether at least one advertising data (AD) structure included in the advertising packet is an AD structure related to a connectionless asset tracking service, and on the basis of security key information, decodes the AD structure related to the connectionless asset tracking service; and determines a location on the basis of the AD structure related to the connectionless asset tracking service, wherein an AD type field of the structure related to the connectionless asset tracking service may comprise a value indicating a connectionless asset tracking service.
