Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional 4G network architecture is used, then device compatibility is maintained, but network capacity and data handling capability are insufficient for 5G requirements
Solution Approach 1:
The patent segments the network architecture into multiple functional layers including access network layer, transport network layer, and service network layer. Each layer is independently managed and can be optimized for specific traffic types, enabling the network to handle diverse traffic scenarios while maintaining high capacity.
Solution Approach 2:
The patent implements dynamic resource allocation and network slicing capabilities that allow the network to adapt its characteristics in real-time based on traffic demands. This enables the same physical infrastructure to dynamically support different service requirements including enhanced mobile broadband, ultra-reliable low-latency communication, and massive machine type communication.
2Productivity
If centralized network control is implemented, then resource allocation efficiency is improved, but network flexibility and adaptability to local conditions decrease
Solution Approach 1:
The patent introduces network controllers and management functions as intermediary elements between centralized network management and distributed access points. These intermediaries receive global network state information from the centralized controller and translate it into local optimization decisions, enabling both centralized coordination and local adaptability.
Solution Approach 2:
The patent enables each access network node to have localized configuration and optimization capabilities tailored to its specific environment and traffic patterns. Each node can independently adjust parameters such as power control, resource allocation, and handover settings while receiving guidance from centralized management, achieving both efficiency and local adaptability.
3Ease of operation
If network functions are virtualized and abstracted, then service delivery optimization is improved, but system complexity increases
Solution Approach 1:
The patent creates virtual copies of network functions and services that can be deployed and managed independently from the physical infrastructure. These virtual network functions can be instantiated, migrated, and scaled without affecting the underlying hardware, simplifying service delivery while managing complexity through abstraction.
Solution Approach 2:
The patent designs universal network function virtualization platforms that can host multiple different services and applications on the same infrastructure. This multi-functionality allows a single complex system to provide diverse services through standardized virtualized components, reducing operational complexity despite architectural sophistication.

AI summary
A framework of abstraction of new and existing 5G radios can enhance capabilities of new and existing micro radios and other short range radio technologies to enable intelligent service delivery, dynamic access learning capability, and network slicing over 5G access networks. Enhancing layer communication for both control and user plane can be tunneled through the hosting layer and exploit a common transport provided by the hosting layer. The tunneling through the hosting layer can also enable the enhance capabilities to access the same radio management functions and can be orchestrated by the same core function.
