Network Capability Invocation Through Dynamic Transmission Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed capability invocation mode in communication network architectures, which limits devices to specific capability invokers, fails to meet the evolving user and industry requirements driven by technologies like big data and artificial intelligence.
Innovation Solution
A method allowing devices in a communication network to flexibly invoke capabilities among each other through a capability invocation process involving request messages, transmission channel establishment, and centralized capability management, enhancing security with token information and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed capability invocation mode is used where terminal devices and application functions can only invoke capabilities of core network devices, then the system structure is simple and easy to manage, but the system cannot meet evolving user and industry requirements driven by big data and artificial intelligence
Solution Approach 1:
The patent enables any device in the communication network (terminal devices, access network devices, core network devices, and application functions) to serve as both capability invokers and capability providers. This universal capability invocation mechanism allows devices to perform multiple roles dynamically, transforming the previously fixed one-way invocation model into a flexible multi-directional capability exchange system that adapts to diverse application scenarios including big data and artificial intelligence
2Adaptability or versatility
If devices are allowed to flexibly invoke capabilities among each other, then the system meets user and industry requirements, but the coordination and security management becomes more complex
Solution Approach 1:
The patent introduces a transmission channel as an intermediary mechanism between capability invokers and providers. This transmission channel establishes dedicated communication paths for capability invocation messages, ensuring secure and reliable transmission. The channel management includes establishment, maintenance, and release phases, with authentication and authorization mechanisms to verify device identities and permission, thereby maintaining security while enabling flexible capability invocation
3Reliability
If a transmission channel is established between capability invoker and provider, then security and coordination are improved, but the channel establishment and management adds system complexity
Solution Approach 1:
The patent implements dynamic transmission channel management where channels are established on-demand based on capability invocation requirements and released when no longer needed. The system dynamically adjusts channel states between established and released, with automatic channel selection and switching capabilities. This dynamic approach ensures that security measures are applied only when necessary, reducing unnecessary complexity while maintaining reliability during active capability invocation

AI summary
A method includes: a first node sends a first request message to a second node. The first request message is used to request the second node to provide a service of a first capability for the first node, and the first capability is a network capability that can be invoked and used. Further, the first node receives, from a third node, an identifier of a transmission channel between the first node and the second node. The transmission channel is used to transmit a capability invocation message corresponding to the first capability. In this method, a capability requester (e.g. the first node) and a capability provider (e.g. the second node) may transmit the capability invocation message about the first capability through the transmission channel established by the third node.
