Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing network slices and selecting appropriate network elements, leading to signaling overload, inconsistent network configurations, and inefficient resource utilization.
Innovation Solution
Implementing a service communication proxy (SCP) and network repository function (NRF) to manage and select network functional entities by transmitting and receiving profile information, enabling efficient network element selection and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional network element selection methods are used, then network configuration simplicity is maintained, but network resource utilization efficiency deteriorates
Solution Approach 1:
The patent introduces a Service Communication Proxy (SCP) as an intermediary entity between network elements and the Service-Based Interface (SBI). The SCP receives service requests, determines target network elements through interaction with the Network Repository Function (NRF), and forwards requests accordingly. This intermediary mechanism enables efficient network element selection and resource allocation without requiring complex configuration changes at each network element, thus improving productivity while managing complexity centrally.
2Device complexity
If network slices are managed without centralized coordination, then system complexity is reduced, but signaling overload occurs
Solution Approach 1:
The SCP is designed as a universal entity that handles multiple functions including service request routing, network element selection, and slice management coordination. By consolidating these functions in a single multi-functional component, the system reduces overall complexity while efficiently managing signaling across multiple network slices, preventing signaling overload through centralized intelligent decision-making.
3Adaptability or versatility
If distributed network element selection is implemented, then system adaptability is improved, but configuration consistency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the SCP interacts with the NRF to obtain current network element status and availability information. The NRF maintains updated profiles of available network elements and their capabilities. When the SCP needs to select a network element, it queries the NRF which provides feedback on suitable candidates based on current network state, service requirements, and element availability. This feedback loop ensures configuration consistency while maintaining adaptability in network element selection.
