Remote Management of Embedded RFID Modules via LLRP Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID-based tracking systems lack a standardized mechanism for remote management of embedded radio modules, limiting system administrators' ability to centrally manage and configure mobile devices and RFID modules.
Innovation Solution
A remote management mechanism using a Low Level Reader Protocol (LLRP) provider application on a remote server and a remote management application on a mobile device, enabling communication for configuration and metadata exchange through the Device Service Provider Interface (DSPI), allowing users to get and set configuration settings across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID modules are integrated permanently or semi-permanently within handheld devices or attached to USB/compact flash slots, then local management of these modules is possible using platform specific software, but system administrators cannot manage these devices and RFID modules from a central management system
Solution Approach 1:
The patent implements a universal communication protocol that enables RFID modules to function both locally (through platform-specific software) and centrally (through web service interfaces). The system uses standardized data formats and communication protocols that allow the same hardware to be managed through multiple interfaces simultaneously, making the system multi-functional without requiring separate hardware configurations.
Solution Approach 2:
The patent introduces a communication protocol as an intermediary layer between the RFID module hardware and the management systems. This protocol acts as a mediator that translates local management commands into standardized messages that can be transmitted over networks to central management systems, enabling centralized control without interfering with existing local management capabilities.
2Ease of operation
If platform specific software is used for local management of RFID modules, then modules can be configured and managed on individual devices, but there is no standardized mechanism for remote management across multiple devices
Solution Approach 1:
The patent segments the management system into distinct layers: a presentation layer for user interaction, a communication layer using standardized protocols for data transmission, and a device layer for hardware-specific operations. This segmentation allows each layer to operate independently with well-defined interfaces, reducing overall system complexity while enabling standardized remote management across diverse devices.
Solution Approach 2:
The patent employs parameter-based configuration where device settings and management policies are represented as structured data parameters that can be transmitted and modified remotely. By changing management from direct hardware control to parameter-based configuration, the system achieves standardized remote management without increasing device complexity, as parameters can be managed centrally and applied across multiple devices.
Data Source
AI summary
A standardized mechanism of remote management of mobile devices using Low Level Reader Protocol (LLRP) is disclosed. An LLRP provider application runs on a server. A remote management application runs on a mobile device. The LLRP provider application and the remote management application communicate using LLRP. The remote management application uses a specific interface, like Device Service Provider Interface (DSPI), to communicate with hardware on the mobile device. The LLRP provider application discovers a mobile device, requests at least one of configuration or metadata information, and receives at least one of configuration or metadata information. The remote management application receives a request for at least one of configuration or metadata information and sends at least one of configuration or metadata information.
