Solution Overview

Problem

Current network optimization techniques lack an open standard interface for proxy signaling between the application and network strata, leading to inefficiencies in cross-stratum information sharing, resource allocation, and increased costs due to potential resource wastage.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidinterface implementation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
ImproveQuality of ServiceVSAvoidsystem coordination complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #23Feedback

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

Engineering Contradiction:
Improveresource wastageVSAvoidinformation exchange overhead
Core Design Contradiction:
Loss of energyVSLoss of information

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.

Inventive Principle:
Principle #35Parameter changes

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.

Inventive Principle:
Principle #2Taking out (Extraction)
