IoT Subscription Notification for Attribute Change Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between action resources and subscribed-to resources in IoT devices is not close enough, leading to inadequate process control and user experience, as users are not timely informed of attribute changes in IoT devices, affecting the validity of intelligent scenes.
Innovation Solution
A method for subscription notification is introduced, where a common service entity creates a subscribed-to resource associated with a monitored application entity and sends a subscription notification to a notified application entity when a resource attribute changes, enabling users to determine the validity of action resources and adjust them accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the IoT management platform manages IoT devices through virtual appliances without close connection between action resources and subscribed-to resources, then the system structure is simple and easy to operate, but the process control is inadequate and users are not timely informed of attribute changes
Solution Approach 1:
The patent implements a feedback mechanism where the IoT management platform actively monitors attribute changes of IoT devices and sends subscription notifications to application terminals. When an attribute change occurs, the platform detects it and feeds back the information through a structured notification containing action resources, subscribed-to resources, and validity indicators, ensuring users are timely informed without manual intervention.
Solution Approach 2:
The patent establishes subscription relationships in advance between action resources and subscribed-to resources. Users pre-configure which attribute changes should trigger notifications and what actions should be taken. This preliminary setup allows the system to automatically execute the correct notification and action sequence when attribute changes occur, eliminating the need for real-time manual configuration.
2Ease of operation
If the system sends detailed subscription notifications with action resources and validity information, then users can independently manage action resource validity, but the notification data structure becomes more complex
Solution Approach 1:
The patent segments the subscription notification into distinct, standardized components: action resources (what should be done), subscribed-to resources (what triggered the notification), validity information (whether the action remains valid), and other relevant attributes. This segmentation allows complex information to be organized in a structured, easily processable format that enables user control while maintaining systematic simplicity.
3Reliability
If the IoT management platform implements close connection between action resources and subscribed-to resources, then process control is improved and user experience is enhanced, but the system complexity increases
Solution Approach 1:
The patent creates a universal subscription notification mechanism that can handle multiple types of IoT devices, attributes, and action resources through a single standardized interface. The notification structure is designed to be multi-functional, accommodating various subscription scenarios (device status changes, location updates, attribute modifications) without requiring separate management systems for each case, thus improving reliability while controlling complexity.
Data Source
AI summary
A novel method, device and medium for subscribing applications. The method may be performed by a common service entity, and includes: creating a subscribed-to resource associated with a monitored application entity based at least in part on an action resource associated with the monitored application entity; and sending a subscription notification corresponding to the action resource to a notified application entity when a resource attribute of the monitored application entity changes. With this method, a subscription notification of an action resource associated with an Internet of Things (IoT) device can be sent to a notified application entity in time in response to an attribute change of resources of the IoT device, so that a user can decide, independently or by an IoT management platform, whether the relevant action resource continues to be valid or invalid, thereby more conforming to actual operation practices of the user and enhancing IoT experience.
