Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy network management paradigms are used, then network infrastructure is maintained, but tailored network capabilities and business models cannot be provided
Solution Approach 1:
The patent segments network functionality into independent Network Functions (NFs) that can be deployed, activated, and deactivated based on specific service requirements. This segmentation enables tailored network capabilities by allowing only the necessary functions to be active for each service type, thereby improving adaptability without requiring complete network redesign.
Solution Approach 2:
The patent implements dynamic network management through the ability to activate and deactivate Network Functions based on service demands. The controller dynamically selects and activates only the necessary NFs for each service, transforming the static legacy network into a dynamic system that adapts to changing requirements while maintaining manageable complexity through automation.
2Productivity
If network resources are always active to support all services, then service availability is ensured, but resource efficiency and cost-effectiveness decrease
Solution Approach 1:
The patent enables dynamic activation and deactivation of Network Functions based on actual service demands. Instead of keeping all resources always active, the system activates only the necessary NFs when services are needed, improving resource efficiency while maintaining service availability through on-demand deployment of required functions.
Solution Approach 2:
The system employs self-service mechanisms where the controller automatically selects and activates appropriate Network Functions based on service requirements without manual intervention. This automation ensures that resources are efficiently allocated and activated only when needed, balancing resource efficiency with service reliability through intelligent decision-making algorithms.
3Adaptability or versatility
If a centralized controller is used for resource orchestration, then service customization is improved, but control system complexity increases
Solution Approach 1:
The patent designs a universal controller that can manage multiple service types and network functions through standardized interfaces and protocols. This multi-functional controller handles diverse service customization requirements using common orchestration mechanisms, thereby improving service adaptability while minimizing control system complexity through consolidation and standardization.

AI summary
A flexible service-based architecture (SBA) for next generation communication networks is described. In an embodiment, a method performed by a system comprising a processor comprises receiving a service request for provision of a data communication service to a communication device via a communication network comprising a plurality of different network resources defined by resource components and sub-components of the resource components. In response to receiving the service request, accessing network resource abstraction information that identifies the resource components, and the sub-components respectively associated with the resource components, and selecting a subset of the different network resources for the provision of the data communication service to the communication device based a service criterion associated with the data communication service. The method further comprises facilitating, by the system, the provision of the data communication service to the communication device via the communication network using the subset of the different network resources.
