Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network slicing methods face issues of network rigidity and performance degradation due to inadequate integration and configuration of Network Functions (NFs), leading to suboptimal resource allocation and Quality of Service (QoS) requirements.
Innovation Solution
A system and method for integrating a network slicing entity with NFs, including standardizing and tuning parameters, and performing Move, Add, Change, or Delete (MACD) functions for Network Slice Selection Function (NSSF), Access and Mobility Management Function (AMF), and Session Management Function (SMF) to generate network slices based on provisioning responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing network slicing methods are used, then network infrastructure can support multiple applications, but network rigidity and performance degradation occur due to inadequate integration of Network Functions
Solution Approach 1:
The patent segments the network slicing process into distinct provisioning stages (NSSF provisioning, SMF provisioning, AMF provisioning) with standardized parameter interfaces. Each Network Function is configured independently with specific parameter sets (slice identifiers, QoS parameters, security configurations), allowing flexible network slicing while maintaining reliable performance through structured integration.
2Adaptability or versatility
If network slicing is implemented to support diverse applications, then resource allocation flexibility improves, but integration complexity of Network Functions increases
Solution Approach 1:
The patent establishes a universal provisioning framework where a standardized set of parameters (slice identifiers, QoS requirements, security setups) can be applied across multiple Network Functions (NSSF, SMF, AMF). This multi-functional approach allows the same parameter structure to govern different NFs, reducing integration complexity while maintaining resource allocation flexibility.
Solution Approach 2:
The patent utilizes parameter changes as the core mechanism for network slicing. By standardizing and tuning parameters (slice identifiers, QoS parameters, security configurations) across different Network Functions, the system achieves flexible resource allocation without increasing integration complexity. Each NF receives standardized parameter sets that can be adjusted to meet diverse application requirements.
3Adaptability or versatility
If Network Functions are integrated without standardized parameters, then implementation flexibility is maintained, but performance degradation occurs due to inadequate configuration
Solution Approach 1:
The patent performs preliminary action by defining and standardizing the set of parameters required for network slicing before actual Network Function integration. The parameter specifications (slice identifiers, QoS parameters, security configurations) are established in advance, ensuring that when NFs are integrated, they receive pre-configured parameter sets with precise values, eliminating configuration errors while maintaining implementation flexibility.
