Network Slice Information Sharing Channels Across Domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems face challenges in efficiently distributing information between network domains due to the need for recognizing endpoint information formats and dynamically sharing topic information, especially during network slice creation, change, or deletion processes.
Innovation Solution
A management system that creates information sharing channels based on identifiers related to network slices, allowing resource and FM/PM information to be shared across domains using a management device, registration devices, and acquisition devices, facilitating seamless information distribution without requiring awareness of endpoint information or formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If REST API is used for information distribution between domains, then data transmission can be performed in a client-server type, but it is necessary for opposing domain devices to detect and follow changes in endpoint information and data format
Solution Approach 1:
The patent introduces an information distribution server as an intermediary component that manages endpoint information and data formats centrally. Domain devices no longer need to directly detect and follow changes in endpoint information; instead, the information distribution server handles these changes and distributes updated endpoint information to relevant devices, thereby reducing the complexity for individual domain devices while maintaining ease of data transmission.
2Adaptability or versatility
If Pub/Sub protocol is used for information distribution, then 1:N communication is supported and data transmission can be performed without considering data format, but topic information must be shared between Publisher and Subscriber in advance
Solution Approach 1:
The patent implements preliminary action by having the information distribution server pre-manage and distribute topic information to Publishers and Subscribers before actual data transmission occurs. This allows the system to maintain the flexibility of Pub/Sub protocol with 1:N communication while reducing the complexity for individual devices, as topic information is handled centrally by the server rather than being manually shared between all Publisher-Subscriber pairs.
3Productivity
If resource information is distributed between domains during network slice creation, then resource creation can be coordinated across domains, but it is necessary to transmit multiple types of information (SID, IP address, endpoint information) between multiple controllers
Solution Approach 1:
The patent merges multiple information distribution functions into a single information distribution server. Instead of having separate mechanisms for distributing SID, IP address, endpoint information, and other resource information between multiple controllers, the system consolidates these functions in one server that manages all resource information distribution across domains. This maintains high network slice creation efficiency while reducing the overall system complexity by eliminating redundant distribution mechanisms.
Solution Approach 2:
The information distribution server is designed as a universal platform that handles multiple types of information distribution (resource information, endpoint information, topic information) and serves multiple functions (managing Publishers, Subscribers, Topics, and endpoint mappings). This multi-functional approach maintains productivity in network slice creation while reducing device complexity by having a single versatile component rather than multiple specialized ones.

AI summary
A management system that manages resources of a network includes a channel management device that creates an information sharing channel according to an identifier related to a network slice for each construction order of the network slice, and a plurality of resource information sharing devices and that share resource information necessary at the time of execution of the construction order between domains of the network via the information sharing channel.
