M2M Control Right Sharing via Virtual Service Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine to machine (M2M) communication systems face limitations in sharing control rights across different communication service networks, preventing user terminals registered with one service provider from controlling M2M devices within another service provider's network.
Innovation Solution
The creation of a virtual service capability layer (SCL) allows for the sharing of control rights between user terminals, enabling unregistered user terminals to control M2M devices by temporary registration and the assignment of specific control rights through a M2M service server, which manages and authenticates access based on shared resource information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control rights are restricted to registered user terminals only, then system security is improved, but control functionality is limited to within the same service network
Solution Approach 1:
The patent introduces a service capability layer as an intermediary component that sits between the user terminal and the M2M device. This virtual SCL creates a controlled access pathway that allows unregistered terminals to request and receive temporary control rights without compromising the core security architecture. The intermediary manages authentication and authorization, enabling cross-network control while maintaining security boundaries.
Solution Approach 2:
The patent implements dynamic control rights that can be temporarily granted and revoked based on service requirements. Instead of static permission assignments, the system dynamically creates virtual SCL instances with specific access rights for specific durations, allowing flexibility in who can control devices and under what conditions, thereby enabling cross-network access without permanent security compromises.
2Adaptability or versatility
If control rights are shared across different service networks, then adaptability is improved, but system security deteriorates
Solution Approach 1:
The patent segments the control access mechanism by creating individual virtual service capability layers for each unregistered terminal that needs access. Instead of opening broad network-wide access, each terminal receives a dedicated, isolated virtual SCL with specific control rights. This segmentation contains potential security risks to individual instances while allowing multiple terminals to access the M2M device through controlled, separate pathways.
3Ease of operation
If virtual service capability layer is created for unregistered terminals, then control accessibility is improved, but device complexity increases
Solution Approach 1:
The patent creates virtual copies of the service capability layer rather than modifying the core system architecture. Each unregistered terminal receives a virtual SCL that mirrors the functionality needed for control access without requiring changes to the underlying M2M device or core service infrastructure. This copying approach simplifies implementation by reusing existing service layer patterns in a virtualized form.

AI summary
The disclosure is related to a method of allowing user terminals to share a control right of a machine to a machine (M2M) device by a M2M service server. The method may include receiving a sharing request message from a first user terminal registered at the M2M service server to share predetermined control rights of a M2M device with a second user terminal, creating a virtual resource for the second user terminal based on information included in the sharing request message, and allowing the second user terminal to control predetermined features of the M2M device based on the created virtual resource in response to a control request message from the second user terminal.
