Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of managing load information between different logical nodes in a network architecture, particularly in 5G systems, where the control plane and user plane are physically separated, leading to inefficiencies in load management and network performance.
Innovation Solution
A method and device for load information interaction that enables a first network node to send a load request message to a second network node, allowing for the exchange of load information across different logical nodes, facilitating load management and balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control plane and user plane are physically separated into different logical nodes, then network flexibility and deployment convenience are improved, but load management capability deteriorates due to inability to exchange load information between nodes
Solution Approach 1:
The patent introduces a load information interaction mechanism as an intermediary between the control plane node and user plane node. This mediator enables load information to be exchanged across the logical node boundary through standardized interfaces, resolving the isolation problem while maintaining the physical separation architecture.
Solution Approach 2:
The patent segments the load management function into independent components that can operate across logical node boundaries. By defining separate load information collection, reporting, and processing modules at different nodes, the system maintains modular architecture while achieving coordinated load management.
2Reliability
If load information interaction is implemented between different logical nodes, then load management capability is improved, but system complexity increases due to additional communication protocols and interfaces
Solution Approach 1:
The patent implements universal load information interaction interfaces that can handle multiple types of load metrics and management scenarios through a unified protocol. This multi-functional approach reduces the need for separate specialized interfaces for different load management tasks, thereby controlling system complexity.
Solution Approach 2:
The patent uses parameter-based configuration to adapt the load information interaction behavior without changing the underlying system structure. By modifying parameters such as load thresholds, reporting intervals, and node identifiers, the system can handle diverse load management requirements while maintaining a consistent interface framework.

AI summary
Provided are a method and a device for load information interaction, a processor and a storage medium. The method includes: sending, by a first network node, a load request message to a second network node, where the load request message is used for indicating configuration information used by the second network node in reporting load information to the first network node; and receiving, by the first network node, the load information reported by the second network node according to the configuration information. The second network node and the first network node belong to different logical nodes in a network. The technical problem that load management cannot be performed when the second network node and the first network node belong to different logical nodes in related technology is solved, and the maximum performance of the network is fully exhibited.
