IAB Node Network Slice Configuration via Collective Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a network configuration using Integrated Access and Backhaul (IAB), efficiently applying network slices to each IAB node in the communication path is challenging, especially when the connection destination of an IAB node changes, requiring manual or individual setting of network slices in numerous nodes.
Innovation Solution
A communication apparatus functioning as an IAB node or donor manages network slices and collectively executes setting changes across the communication path when an IAB node changes its connection destination, ensuring that network slices are efficiently applied and updated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network slices are manually or individually set in each IAB node, then network slice configuration can be precisely controlled, but the operation time and complexity increase significantly when connection destinations change
Solution Approach 1:
The patent merges the network slice setting operations for multiple IAB nodes into a single collective operation. When a connection destination changes, the control apparatus performs unified setting of network slices across all affected IAB nodes simultaneously, rather than requiring individual manual configuration at each node. This combining approach directly reduces operation time and simplifies the setting process.
Solution Approach 2:
The patent introduces a control apparatus as an intermediary between the network management system and IAB nodes. This intermediary automatically manages network slice settings across multiple nodes, eliminating the need for manual individual configuration. The control apparatus receives connection change notifications and autonomously performs collective network slice setting, significantly reducing operational complexity and time.
2Productivity
If network slices are collectively set across the communication path, then the setting efficiency improves, but the system complexity increases due to automated control mechanisms
Solution Approach 1:
The control apparatus is designed with multi-functionality, handling both connection change notifications and network slice setting operations within a single system. This universal approach allows the same apparatus to manage diverse tasks (connection management and slice configuration), improving overall efficiency without proportionally increasing complexity. The apparatus serves multiple functions that would otherwise require separate systems.
Solution Approach 2:
The system implements self-service mechanisms where the control apparatus automatically detects connection destination changes and autonomously performs network slice setting without external intervention. The system serves itself by monitoring its own state changes and triggering appropriate configuration actions, which improves productivity while keeping operational complexity manageable through automation rather than manual processes.
3Manufacturing precision
If individual network slice settings are performed in each IAB node, then precise control over each node is achieved, but the adaptability to connection changes deteriorates
Solution Approach 1:
The control apparatus performs preliminary preparation of network slice configurations before connection changes occur. When a connection destination change is detected, the system has pre-configured or pre-planned network slice settings ready to be applied collectively. This preliminary action ensures that precise configuration is maintained while enabling rapid adaptation to connection changes, as the system doesn't need to calculate or determine settings in real-time during the transition.

AI summary
A communication apparatus that operates as an IAB node connected to one of an IAB donor and a communication path formed by the IAB donor in a relay transmission network complying with Integrated Access and Backhaul (IAB) regulations transmits a message for causing the IAB node connected to the communication path to set a network slice.
