Engineering Contradiction Analysis
1Productivity
If conventional mobile network technologies are used to manage resources, then network coverage and basic service delivery are maintained, but real-time resource management becomes difficult and complex due to exponential growth of wireless devices and services
Solution Approach 1:
The patent introduces a policy-based SDN controller as an intermediary between the network infrastructure and service management functions. This controller centralizes resource management decisions, separating control plane functions from data plane operations, thereby simplifying real-time resource management while handling exponential device growth through automated policy enforcement
Solution Approach 2:
The system implements dynamic resource allocation through real-time policy evaluation and adjustment. Network resources are dynamically configured based on current traffic conditions, service requirements, and network state, allowing the system to adapt to exponential device growth without manual reconfiguration or static allocation schemes
2Reliability
If static network configuration is used, then network stability is maintained, but user experience and network performance cannot be optimized in real-time
Solution Approach 1:
The patent implements continuous feedback loops where the SDN controller monitors network performance metrics, user experience indicators, and resource utilization in real-time. This feedback drives dynamic policy adjustments that optimize network performance while maintaining stability through controlled, policy-based changes rather than reactive reconfigurations
Solution Approach 2:
The system uses policy-based pre-configuration and predictive resource allocation. Network resources are pre-provisioned and configured according to defined policies that anticipate future network states and service requirements, allowing the system to maintain stability while being prepared for real-time optimization when conditions change
