Service Capabilities Layer Resource Propagation Across Domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine-to-machine (M2M) implementations are limited in that a service capabilities layer (SCL) entity can only announce resources associated with an application to other SCL entities within the same network domain, and do not allow the announcement of SCL resources across different domains.
Innovation Solution
The solution enables SCL entities to advertise and announce resources, including subresources, across different network domains through inter-domain reference points, allowing access to SCL resources and resources in one network domain by M2M entities in other domains, using a mechanism that includes generating requests to advertise resources and transmitting them between nodes via inter-domain reference points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SCL entities announce resources only within the same network domain, then the announcement mechanism remains simple and contained, but the accessibility and interoperability of resources across domains is limited
Solution Approach 1:
The patent introduces an intermediary mechanism (the SCL entity itself acting as a mediator) that propagates resource announcements from one domain to another through defined reference points. This allows resources to be shared across domains without requiring direct complex interactions between all entities, resolving the contradiction by enabling cross-domain access while maintaining a structured, manageable propagation approach.
2Adaptability or versatility
If the announcement mechanism is extended to support cross-domain resource propagation, then resource sharing capability is improved, but the complexity of the announcement procedure increases
Solution Approach 1:
The patent segments the announcement procedure into distinct phases: local resource announcement within the originating domain, and subsequent propagation to other domains through inter-domain reference points. This segmentation allows the complex cross-domain propagation to be broken down into manageable steps, reducing the perceived complexity while enabling the enhanced capability.
Solution Approach 2:
The SCL entity is designed to perform multiple functions: it announces resources locally within its own domain and simultaneously propagates those announcements to other domains. This multi-functionality consolidates what could be separate complex mechanisms into a single unified entity, reducing overall system complexity while achieving cross-domain resource sharing.
3Adaptability or versatility
If SCL entities can announce resources to entities in other network domains, then interoperability is improved, but the scope and reach of the announcement mechanism expands
Solution Approach 1:
The patent extends the announcement mechanism from a two-dimensional scope (within-domain only) to a three-dimensional scope by adding the domain boundary as a new dimension. Resource announcements are propagated not just within the originating domain but also across domain boundaries through defined reference points, enabling interoperability without overwhelming the mechanism, as the propagation follows a structured dimensional expansion rather than a flat expansion.
