Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slices are divided based on common network infrastructure using virtualization technologies, then network service diversity is improved, but system feature configuration management becomes complex and unresolved
Solution Approach 1:
The patent introduces a Network Slice Management Function (NSMF) as an intermediary between the network slice configuration and the Network Repository Function (NRF). The NSMF receives configuration information including network slice information, system features, and corresponding NF services, then processes and forwards this information to the NRF for storage. This intermediary structure resolves the complexity by centralizing the configuration management logic in the NSMF, which acts as a mediator that translates diverse service requirements into standardized configuration data that the NRF can manage efficiently.
2Adaptability or versatility
If multiple network slices support different system features, then service capability is improved, but configuration management and status monitoring become difficult
Solution Approach 1:
The patent implements a universal configuration management approach where the NSMF handles multiple functions including receiving configuration information, processing NF service status information, and updating the NRF. The NRF serves as a universal repository that stores diverse configuration data for multiple network slices and their corresponding system features. This multi-functional design allows the system to manage various service capabilities through a unified interface and centralized storage, making configuration management and status monitoring easier despite the diversity of network slices.
Solution Approach 2:
The patent establishes a feedback mechanism where network elements send NF service status information to the NSMF, which then updates the NRF with current status data. This feedback loop enables continuous monitoring of system features across multiple network slices. The NRF can subsequently provide this status information to requesting network elements, creating a closed-loop system that automatically tracks and reports the state of configured features, thereby improving ease of operation for configuration management and status monitoring.

AI summary
This application provides a configuration method and apparatus. The method includes: receiving, by a network repository network element, configuration information from a network slice management network element, where the configuration information includes information about a network slice, a system feature supported by the network slice, a network function NF corresponding to the system feature, and an NF service corresponding to the NF; and storing, by the network repository network element, the configuration information. Based on this solution, information related to the network slice can be configured for the network repository network element.
