Cross-Network Slice Collaboration for End-to-End Service Assurance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies are incapable of providing end-to-end service quality assurance across multiple network slices, specifically for industry customers requiring integrated management of both public and non-public networks.
Innovation Solution
A cross-network slice collaboration method and device, utilizing a Network Slice Capability Enablement Server (NSCE-S), which performs service performance monitoring and resource optimization across both Non-Public Network (NPN) and Public Land Mobile Network (PLMN) slices, integrating performance and status information to provide a unified service interface for industry applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current single-slice management technology is used, then slice management is simple, but end-to-end service quality assurance across multiple network slices cannot be achieved
Solution Approach 1:
The patent introduces a Network Slice Management Function (NSMF) as an intermediary component that coordinates between multiple Network Slice Selection Functions (NSSFs) and network slices. The NSMF receives service requirements from application functions, selects appropriate slices, and manages resource allocation across slices, enabling end-to-end service quality assurance while abstracting the complexity of multi-slice management from individual slice controllers.
2Adaptability or versatility
If multiple network slices are managed independently, then each slice can be optimized individually, but cross-network collaboration and resource sharing cannot be achieved
Solution Approach 1:
The patent designs the Network Slice Management Function (NSMF) with multi-functional capabilities that enable it to perform slice selection, resource allocation, performance monitoring, and coordination across different network slices and types (PLMN and NPN). This universal management approach allows diverse slice types to be managed through a common framework, achieving cross-network collaboration while maintaining architectural simplicity.
3Reliability
If public network and non-public network slices are managed separately, then security and isolation are maintained, but integrated resource allocation and optimization cannot be achieved
Solution Approach 1:
The patent implements a segmented management architecture where the NSMF performs high-level cross-slice resource allocation and policy management, while individual NSSFs handle slice-specific configuration and enforcement. This segmentation allows PLMN and NPN slices to maintain security isolation through separate NSSF control planes, while the NSMF enables integrated resource optimization by coordinating allocations across both slice types at the management layer.

AI summary
A cross-network slice collaboration method, a device and a network slice capability enablement server are provided, the method includes: receiving a first request sent by an application server; where the first request carries an identifier of a first application; obtaining Non-Public Network (NPN) slice information corresponding to the first application and specific slice information corresponding to the first application in a Public Land Mobile Network (PLMN); performing, according to the NPN slice information and the specific slice information in the PLMN, a service performance monitoring and/or slice resource optimization for the first application.
