Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of proprietary operation and maintenance systems is used for multi-vendor radio access network nodes, then configuration consistency can be achieved, but the complexity and time required for deployment increases significantly
Solution Approach 1:
The system enables radio access network nodes to automatically exchange capability information with neighboring nodes without manual configuration. Each node autonomously determines its supported capabilities and communicates them to adjacent nodes, which then automatically configure themselves to ensure consistent interworking across vendor boundaries.
Solution Approach 2:
The patent implements a feedback mechanism where radio access network nodes continuously exchange capability information with neighboring nodes. This feedback loop ensures that each node is aware of its neighbors' capabilities, enabling automatic adaptation and consistent configuration without manual intervention throughout the network deployment lifecycle.
2Reliability
If manual configuration is performed by mobile operators for each vendor-specific operation and maintenance system, then consistent configuration between neighboring nodes is ensured, but the time and resources required for integration and testing increase
Solution Approach 1:
The system performs preliminary capability exchange between radio access network nodes during network setup or before interworking is required. Each node proactively communicates its capabilities to neighboring nodes in advance, enabling automatic configuration preparation and eliminating the need for time-consuming manual integration and testing phases.
3Adaptability or versatility
If proprietary operation and maintenance systems from different vendors are used, then each vendor can optimize their own nodes, but the ability to ensure consistent configuration across vendor boundaries deteriorates
Solution Approach 1:
The patent implements a universal capability exchange mechanism that works across different vendor-specific operation and maintenance systems. The capability information exchange protocol is vendor-agnostic, allowing nodes from different vendors to communicate their capabilities and achieve consistent configuration while maintaining their proprietary system optimizations.
4Extent of automation
If dynamic capability exchange is implemented between radio access network nodes, then automatic configuration and operation is enabled, but the complexity of the interaction protocols increases
Solution Approach 1:
The patent standardizes the capability information exchange format and protocol between radio access network nodes from different vendors. By homogenizing the interaction interface and data structures, the system enables automatic operation while minimizing protocol complexity and making implementation more manageable across different vendor ecosystems.
