Automated Network Slice Selection Policy Rule Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual construction of Network Slice Selection Policy (NSSP) in 5G mobile networks is cumbersome and time-consuming, requiring operators to manually associate multiple applications with appropriate network slices, which is inefficient and labor-intensive.
Innovation Solution
A method and system for automatically creating NSSP rules based on application identifiers, application profiles, and application providers, utilizing a Network Exposure Function (NEF) and Unified Data Management (UDM) node to determine and associate network slice identifiers, thereby automating the NSSP construction process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual construction of NSSP is used, then policy accuracy can be maintained, but operator workload and time consumption increase significantly
Solution Approach 1:
The system enables self-service by allowing the network to automatically generate and update NSSP rules based on application profiles and network slice requirements, eliminating the need for manual operator intervention while maintaining policy accuracy through automated decision-making algorithms
Solution Approach 2:
An automated policy generation function acts as an intermediary between application requirements and network slice selection, translating application profiles into appropriate NSSP rules without requiring direct manual configuration, thus reducing operator workload while ensuring accurate policy creation
2Ease of operation
If manual NSSP construction is implemented, then detailed control over each application can be achieved, but the process becomes cumbersome and labor-intensive
Solution Approach 1:
The system merges multiple individual application configurations into a unified automated policy generation process, where the automated function simultaneously processes multiple application profiles and generates corresponding NSSP rules, simplifying the operational process while maintaining detailed control capabilities
Solution Approach 2:
The automated policy generation function serves as a universal solution that can handle diverse application types and requirements through a single multi-functional system, eliminating the need for separate manual configuration processes for each application and reducing overall process complexity
3Extent of automation
If automated NSSP creation is implemented, then operator intervention is reduced, but the system complexity increases
Solution Approach 1:
The system achieves self-service automation where the network automatically monitors application requirements, selects appropriate network slices, and updates NSSP rules without operator intervention, managing system complexity through autonomous decision-making rather than requiring complex manual management interfaces
Solution Approach 2:
The automated system incorporates feedback mechanisms that continuously monitor application performance and network slice utilization, using this information to dynamically adjust and optimize NSSP rules, thereby managing system complexity through adaptive learning rather than static complex configurations

AI summary
Apparatuses, methods, and systems are disclosed for creating a network slice section policy (“NSSP”) rule. One apparatus includes a processor and a transceiver for communicating with a network function in a mobile communication network. The processor receives a first request from the network function, the first request comprising a list of one or more application identifiers and a corresponding application profile and application provider for each application identifier. The processor determines one or more network slice identifiers for each application identifier using the corresponding application profile and application provider. The processor also creates a NSSP rule for each application identifier in the list of application identifiers, the NSSP rule containing the application identifier and the associated one or more network slice identifiers.
