M2M IoT Control Message Verification via Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine-to-machine (M2M) or Internet of Things (IoT) communication systems, there is a lack of assurance that the resource indicating the result of a control operation corresponds to the actual result, leading to potential discrepancies in the status of M2M/IoT devices.
Innovation Solution
A method is introduced where a first M2M/IoT device transmits a resource creation request to a third M2M/IoT device, including a control message and an indicator to ensure processing, and checks if the content of the control message matches the control result notification, with options to apply the result to the device status or retransmit the request if they do not match.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If resource-based control operation is performed in M2M/IoT system, then device control capability is improved, but reliability of control operation result is deteriorated due to lack of assurance between resource status and actual device status
Solution Approach 1:
The patent implements a feedback mechanism where the controlled device sends back control result notification containing the actual execution status. The controlling device compares this feedback with the expected resource status to verify control operation reliability, resolving the contradiction between automation capability and result reliability.
Solution Approach 2:
The patent introduces preliminary actions including sending control messages before execution, receiving control result notifications after execution, and performing status comparisons. These preliminary and follow-up actions ensure that the resource-based control operation reliably reflects the actual device state, addressing the reliability concern while maintaining automation.
2Reliability
If control result verification is implemented by comparing resource status with actual device status, then control operation reliability is improved, but communication overhead and processing time are increased
Solution Approach 1:
The patent applies partial verification by selectively comparing only critical status parameters rather than performing exhaustive verification of all device states. This approach maintains control operation reliability for essential functions while reducing unnecessary verification time and processing overhead.

AI summary
Provided is a method for guaranteeing the processing of a control operation in a wireless communication system, and the method is performed by a first machine-to-machine (M2M)/Internet of Things (IoT) device and can comprise the steps of: transmitting, to a third M2M/IoT device, a resource generation request for delivering a control message for directing a control operation of a second M2M/IoT device, wherein the resource generation request includes the contents of the control message, an indicator requesting a processing guarantee of the control operation or an identifier of the resource generation request; receiving a resource generation response to the resource generation request from the third M2M/IoT device; receiving a control result notification including a processing result of the control operation according to the indicator from the third M2M/IoT device, wherein the control result notification includes the identifier of the resource generation request; and checking whether the contents of the control message match the contents of the control result notification.
