M2M Resource Announcement via Service Capability Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current M2M communication systems face challenges in efficiently managing network resources, particularly in propagating and accessing resources across multiple networks, which affects the performance of machine-type communication entities.
Innovation Solution
The implementation of a hosting service capability layer (SCL) that receives requests to announce resources, creates a representation of the resource, and propagates it across multiple SCLs using an mId interface, determining accessibility and security constraints to choose appropriate SCLs for announcement, thereby optimizing resource management and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resources are propagated across multiple networks in M2M communication systems, then resource accessibility and system performance are improved, but network complexity and resource management overhead increase
Solution Approach 1:
The patent introduces Service Capability Layers (SCLs) as intermediary entities that manage resource announcements and de-announcements across networks. The hosting SCL receives resource announcement requests, creates resource representations, and propagates them to announced-to SCLs, while the mId interface serves as a standardized mediation mechanism. This intermediary structure improves resource management efficiency by centralizing control while managing network complexity through standardized interfaces.
2Loss of time
If resource announcements are propagated to multiple SCLs, then resource discovery time is reduced, but security constraints and access control requirements increase system complexity
Solution Approach 1:
The patent implements preliminary security validation by determining accessibility and evaluating security constraints before propagating resource announcements to announced-to SCLs. The hosting SCL performs access control checks and security validations in advance, only propagating announcements to authorized SCLs. This preliminary action reduces resource discovery time for authorized entities while managing access control complexity through pre-validation rather than continuous checking.
3Adaptability or versatility
If a standardized mId interface is implemented for resource propagation, then interoperability between different SCLs is improved, but implementation complexity and protocol overhead increase
Solution Approach 1:
The patent creates a universal mId interface that enables multiple SCLs from different networks to communicate and propagate resource announcements using a standardized protocol. The interface defines common message formats, announcement procedures, and de-announcement mechanisms that work across diverse network environments. This universality improves interoperability by allowing different SCL implementations to work together while managing protocol complexity through standardization rather than custom point-to-point solutions.

AI summary
Systems, methods, and instrumentalities are disclosed to propagate announcement and de-announcement of a resource across one or more networks. A first entity, which may be a hosting service capability layer (SCL), may receive a request from an issuer to announce a resource. The first entity may create a representation of the resource. The representation may be referred to as an announced resource. The first entity may send an announce resource request to a second entity (e.g., an announced-to SCL), which may be registered with the first entity. The announce resource request may be sent over an mId interface. The first entity may receive a first response from the second entity over the mId interface indicating that the second entity created the announced resource.
