Engineering Contradiction Analysis
1Productivity
If an open standard interface for proxy signaling between application and network strata is implemented, then cross-stratum information sharing and resource allocation efficiency improve, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent introduces a proxy signaling interface that acts as an intermediary between the application stratum and network stratum. This intermediary component enables standardized information exchange and coordination without requiring direct complex interactions between the two strata, thereby improving resource allocation efficiency while managing implementation complexity through a dedicated mediation layer.
Solution Approach 2:
The proxy signaling interface is designed as a universal standard that can be applied across multiple network configurations and application types. By creating a multi-functional interface that handles various cross-stratum coordination scenarios (resource allocation, information sharing, service management), the solution improves overall productivity without proportionally increasing complexity, as the same interface structure serves multiple purposes.
2Reliability
If integrated optimization of application and network resources is implemented, then Quality of Service and resource utilization improve, but system complexity and coordination overhead increase
Solution Approach 1:
The patent segments the optimization function into distinct components: application stratum entities, network stratum entities, and the proxy signaling interface connecting them. This segmentation allows each component to be optimized independently while maintaining overall QoS through coordinated interaction. The segmentation reduces system coordination complexity by creating clear boundaries and responsibilities for each segment.
Solution Approach 2:
The integrated optimization system implements feedback mechanisms where the proxy signaling interface continuously exchanges information between application and network strata regarding resource utilization, service performance, and allocation status. This feedback loop enables dynamic adjustment of resource allocation to maintain high QoS while avoiding excessive coordination overhead through efficient feedback signaling.
3Loss of energy
If cross-stratum message exchange for resource optimization is enabled, then resource wastage decreases and cost efficiency improves, but information exchange complexity and protocol overhead increase
Solution Approach 1:
The proxy signaling interface employs parameter changes to efficiently represent resource allocation and status information in cross-stratum messages. By optimizing message parameters to carry only essential information needed for resource optimization decisions, the system reduces resource wastage while minimizing information exchange overhead. Parameters are dynamically adjusted based on current network and application states.
Solution Approach 2:
The patent extracts and isolates the essential cross-stratum signaling functions into a dedicated proxy interface, separating critical resource optimization information from general protocol overhead. This extraction allows the system to focus message exchange on only the necessary information for reducing resource wastage, eliminating unnecessary data transmission and reducing information exchange complexity.
