Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing is implemented to support diverse applications and services in 5G networks, then adaptability and service customization are improved, but device complexity and network configuration complexity increase
Solution Approach 1:
The network is divided into multiple independent network slices, each optimized for specific services (e.g., enhanced mobile broadband, ultra-reliable low-latency communication, massive IoT). This segmentation allows customized configurations for different services while managing complexity through modular design.
Solution Approach 2:
A universal network slice management system is implemented that can handle multiple service types through standardized interfaces and procedures. The management entity provides multi-functional capabilities to configure, monitor, and control various network slices using unified methods.
2Adaptability or versatility
If multiple subnetworks are deployed to handle different communication requirements, then service diversity and adaptability are improved, but resource management complexity and overhead increase
Solution Approach 1:
A network slice management entity acts as an intermediary between the core network and individual network slices. This mediator handles resource allocation, configuration, and coordination across multiple subnetworks, reducing management overhead by centralizing control functions.
Solution Approach 2:
Network parameters such as bandwidth allocation, latency requirements, and connection density are dynamically adjusted based on service requirements and network conditions. This allows flexible resource management across multiple subnetworks without requiring complex static configurations.
3Productivity
If network slicing is used to optimize specific applications, then communication performance for targeted services is improved, but overall network complexity and management overhead increase
Solution Approach 1:
Network slices are pre-configured with optimized parameters and resources based on anticipated service requirements. This preliminary configuration reduces real-time management overhead while maintaining high communication performance for targeted applications.
Solution Approach 2:
The network slice management system implements feedback mechanisms that monitor communication performance and automatically adjust resource allocation. This closed-loop control maintains optimal performance while reducing manual management overhead through automated decision-making.
