Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single network structure is used to support diverse applications, then device complexity is reduced, but communication performance cannot be optimized for specific service requirements
Solution Approach 1:
The network is segmented into multiple sub-networks (network slices) that can be independently configured and optimized for different service requirements. Each slice can be tailored for specific applications such as enhanced mobile broadband, ultra-reliable low-latency communication, or massive IoT, allowing performance optimization without increasing overall system complexity through standardized management interfaces.
2Device complexity
If network resources are statically allocated, then device complexity is reduced, but adaptability to different service requirements deteriorates
Solution Approach 1:
Network resources are dynamically allocated through automated resource management that adjusts resource distribution based on real-time service requirements and network conditions. The system can dynamically create, modify, or release network slices to match varying demand patterns, enabling adaptability to different service types while maintaining manageable complexity through automated decision-making algorithms.
3Reliability
If multiple identification entities are deployed in different sub-networks, then authentication reliability is improved, but device complexity increases
Solution Approach 1:
Multiple identification entities deployed across different sub-networks implement a unified authentication framework where each entity performs the same core authentication functions but operates within its specific sub-network context. This universal approach ensures consistent authentication reliability across all slices while managing complexity through standardized protocols and centralized coordination mechanisms.
