IoT Service Platform Device Triggering Message Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device triggering methods in oneM2M communications do not effectively implement cancellation or updating of device triggering messages, which is a limitation in managing device activation and communication in IoT environments.
Innovation Solution
An Internet of things service platform sends a first device triggering message and stores an identifier, then sends a second message to the underlying network to cancel or update the first message, using a second identifier stored in a corresponding resource, allowing for the deletion or updating of resources as necessary upon successful response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device triggering message is sent to activate a device in oneM2M communications, then the device can be activated and communication can be established, but the method cannot implement cancellation or updating of the triggering message
Solution Approach 1:
The patent applies preliminary action by storing the identifier of the first device triggering message before sending the second message. This pre-stored identifier enables the subsequent cancellation or update operation to successfully reference and modify the original triggering message, resolving the inability to manage triggering messages dynamically.
Solution Approach 2:
The patent introduces an identifier as an intermediary element between the first device triggering message and the second device triggering message. This identifier acts as a reference key that enables the second message to locate, cancel, or update the first message, providing the missing management capability while maintaining system reliability.
2Productivity
If device triggering messages are sent frequently to manage device activation, then device communication can be established, but system complexity increases due to lack of cancellation/update mechanisms
Solution Approach 1:
The patent extracts the identifier information from the device triggering message and stores it separately. This extraction allows the system to manage triggering messages more efficiently by referencing stored identifiers rather than handling complete message copies, reducing management complexity while maintaining activation productivity.

AI summary
A method and apparatus for processing device triggering information are provided. The method includes the following acts. An Internet of things service platform sends to an underlying network a first device triggering message for triggering a device registered on the Internet of things service platform, and stores a first identifier corresponding to the first device triggering message (S302). The Internet of things service platform sends a second device triggering message to the underlying network, wherein the second device triggering message contains the first identifier, and the second device triggering message is used for indicating the underlying network to cancel or update the first device triggering message according to the first identifier (S304). By the solution, a problem that a device triggering method may not implement cancelation or updating of a device triggering message is solved, and cancelation or updating of the device triggering message is achieved.
