Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network architectures do not consider the diverse characteristics of all network nodes, such as coverage area and mobility, leading to inefficiencies in connecting and communicating between different types of nodes, particularly in future radio networks that include movable and immovable access nodes like satellites and base stations.
Innovation Solution
A service-oriented network architecture with an edge cloud, access cloud, and core cloud, where edge cloud nodes, including movable terminals, provide services to user terminals through no-connection-based interfaces, and access and core clouds facilitate information sharing and processing, enabling flexible and dynamic communication across various nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional network architecture with single types of network nodes is used, then network structure is simple, but it cannot accommodate diverse characteristics of different network nodes (movable and immovable access nodes)
Solution Approach 1:
The network architecture is segmented into three distinct cloud layers: edge cloud containing movable access nodes, access cloud containing immovable access nodes, and core cloud containing core network elements. This segmentation allows each layer to be optimized for its specific node types while maintaining overall system adaptability without excessive complexity.
Solution Approach 2:
The patent creates a universal network architecture that can handle both movable and immovable access nodes through standardized interfaces and protocols across all cloud layers. The service-oriented framework provides multi-functional capabilities to accommodate diverse node characteristics while maintaining a unified structural approach.
2Productivity
If connection-based interfaces are used for all network nodes, then communication reliability is ensured, but mobility management becomes inefficient for movable terminals
Solution Approach 1:
The patent implements dynamic interface selection based on node mobility characteristics. Movable access nodes in the edge cloud utilize no-connection-based interfaces that enable rapid connection establishment and release, optimizing mobility management efficiency. Immovable access nodes in the access cloud use connection-based interfaces that ensure communication reliability for stationary nodes.
3Loss of time
If service provisioning requires connection establishment, then communication reliability is improved, but service response time increases for movable terminals
Solution Approach 1:
The architecture pre-establishes service capabilities at edge cloud nodes before actual service requests occur. Movable terminals can quickly access pre-configured services without going through lengthy connection establishment procedures, reducing service response time while maintaining reliability through pre-validated service paths.
