IoT Event Subscription Notification Method for Data Enrichment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing IoT systems carry a small amount of information in the data provided by public service entities, limiting their application scenarios.
Innovation Solution
An event subscription notification method is implemented, where a network side device creates a subscription resource with an event notification rule, determines if subscribed data meets this rule, and generates a notification when it does, thereby increasing the information carried in the data and expanding its application scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is provided by public service entities in IoT systems, then data can be shared across applications, but the amount of information carried in the data is limited
Solution Approach 1:
The patent segments the data processing function by introducing event notification rules that separate raw data from processed information. The network side device creates subscription resources with specific event notification rules, allowing applications to subscribe to specific event types (e.g., device status changes, alarm conditions) rather than receiving all raw data, thus enriching information content while maintaining data sharing capabilities
Solution Approach 2:
The patent introduces an intermediary layer (network side device with event notification mechanism) between data providers and applications. This intermediary processes raw data against event notification rules and generates enriched event notifications, thereby increasing information content without requiring changes to the original data structure or application scenarios
2Adaptability or versatility
If event notification rules are implemented to enrich data information, then application scenarios are expanded, but data processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining event notification rules before data processing occurs. The network side device creates subscription resources with event notification rules in advance, so when data arrives, it can be processed against these pre-established rules without complex real-time analysis, thus expanding application scenarios while controlling processing complexity
Solution Approach 2:
The patent changes the parameter of data processing from raw data handling to rule-based event filtering. By transforming the processing approach from processing all data to processing data against specific event notification rules (with parameters like event type, condition thresholds), the system expands application scenarios while managing complexity through parameterized rule evaluation
