IoT Resource Association via Connection State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of IoT, individual data resources from various devices are not associated with each other, hindering comprehensive analysis and affecting the construction of big data systems.
Innovation Solution
A method for associating resources involves detecting connection states between entities and sending requests to a common service entity to establish or cancel associations, using group resources with attributes like association start and end times, member lists, and enabling identifiers to manage these associations dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If data from separate IoT devices are transmitted to a common service platform and stored as separate data, then data storage and management is simplified, but comprehensive data analysis is hindered and big data system construction is affected
Solution Approach 1:
The patent segments data management into two layers: individual device data storage (maintaining simplicity) and association relationship storage (enabling analysis). Each device data is stored separately with unique identifiers, while association relationships are stored as separate entities linking these identifiers, thus preserving both ease of storage and data relationships.
Solution Approach 2:
The patent introduces an intermediary association entity that connects separate device data. This association entity contains identifiers of related devices and their relationship types, acting as a mediator that preserves data relationships without requiring direct integration of the original device data, thus maintaining storage simplicity while enabling comprehensive analysis.
2Loss of information
If associations between resources are established manually or through complex protocols, then data relationships can be maintained, but system complexity and operation difficulty increase
Solution Approach 1:
The patent implements self-service association establishment where devices automatically generate association requests based on their own state changes (e.g., connection events). The devices themselves initiate the association process by sending requests to the service platform, eliminating the need for complex external coordination protocols while maintaining accurate data relationships.
Solution Approach 2:
The patent uses preliminary action by pre-defining association templates and relationship types in the system. When devices need to associate, they simply reference these pre-established templates rather than creating complex relationships from scratch, significantly reducing system complexity while maintaining comprehensive data relationship tracking.
3Stability of the object's composition
If static associations are established between resources, then data relationships are stable, but flexibility to adapt to changing connection states is reduced
Solution Approach 1:
The patent implements dynamic associations where relationship status can change between established and canceled states. Devices can send cancellation requests to terminate associations when connections are lost, and re-establishment requests when connections are restored. This dynamic mechanism maintains stable recorded relationships while adapting flexibly to changing real-time connection states.

AI summary
There is disclosed a method for associating at least two resources, a communication terminal and a communication node device. The method comprises detecting a connection state for entities respectively corresponding to the at least two resources; and sending a first request to a common service entity to establish an association between the at least two resources after it is detected that the connection state is established by the entities.
