M2M Resource Management via Mapped Address Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of network applications performing operations on device resources in M2M systems is increased due to the need to handle different URI organizational structures for resources stored on the platform versus those stored on devices, leading to inefficient information sharing and high deployment costs across vertical industries.
Innovation Solution
A method and management apparatus that receive a mapped address for a device resource, determine its location, and generate a second request to perform operations directly on the device, providing a uniform device resource access interface to reduce complexity and improve convenience for network applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the M2M platform stores all device resources on the platform, then network applications can access resources through a unified interface, but resources that need to be stored on devices cannot be accessed efficiently
Solution Approach 1:
The management apparatus acts as an intermediary between network applications and device resources. It receives requests using mapped addresses, determines the actual location of resources (platform or device), and forwards requests to the appropriate location. This mediator approach allows unified interface while maintaining efficient direct device access when needed.
Solution Approach 2:
The patent introduces a mapped address dimension that maps to either platform resources or device resources. This additional addressing dimension allows the system to distinguish between resources stored on the platform versus devices, enabling both unified access and efficient direct access through a single interface mechanism.
2Reliability
If the M2M platform uses different URI organizational structures for platform-stored and device-stored resources, then resource location can be distinguished, but network application processing complexity increases
Solution Approach 1:
The management apparatus provides a universal interface that handles both platform resources and device resources through the same mapped address format. This multi-functional approach eliminates the need for network applications to process different URI structures, as the management apparatus统一 handles all resource types through a single interface paradigm.
3Ease of manufacture
If M2M systems implement strong coupling between devices and applications, then vendor-specific solutions can be deployed, but deployment cost increases and information sharing becomes difficult
Solution Approach 1:
The patent segments the M2M system into independent components: management apparatus, network applications, and devices. The management apparatus manages resource mapping and routing independently from devices and applications. This segmentation allows vendor-specific solutions to be deployed while maintaining standardized interfaces that facilitate information sharing across isolated systems.

AI summary
A method for performing an operation on a device resource includes: receiving a first request, which is requests an operation on a device resource, where a destination address of the first request is a mapped address of the device resource on a management apparatus; determining, that the device resource is created on a device corresponding to the device resource; generating a second request for performing an operation on the device resource on the device; and transmitting the second request to the device. A management apparatus for performing an operation on a device resource is also provided. By using the present invention, the complexity for the network application to perform an operation on the device resource can be reduced, and the convenience for the network application to perform an operation on the device resource can be improved. Therefore, extensive application of M2M can further be promoted.
