Network Node Reconfiguration for Conditional Handover Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G systems lack a design for changing or canceling cell change configuration information after a source node informs a target node of cell change configuration information during conditional handover, limiting network flexibility and efficiency.
Innovation Solution
A reconfiguration method where a first network node sends a reconfiguration request for cell change configuration information to a second network node and obtains a response to reconfigure or delete this information, allowing for configuration changes, deletions, and resource management even after conditional cell change configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conditional handover configuration information is sent from source node to target node, then handover reliability is improved, but network flexibility deteriorates because configuration changes or cancellations cannot be made after sending
Solution Approach 1:
The patent introduces a dynamic reconfiguration mechanism that allows the source node to change or cancel conditional handover configuration information after it has been sent to the target node. This is achieved through a reconfiguration request message exchanged between network nodes, enabling the system to adapt to changing conditions while maintaining the initial reliability benefits of conditional handover configuration.
2Reliability
If conditional cell change configuration is performed, then handover failure is avoided, but resource wastage occurs due to untriggered configurations that cannot be cancelled
Solution Approach 1:
The patent enables the network to discard untriggered conditional handover configurations through the reconfiguration mechanism. When conditions change or the handover is no longer needed, the source node can send a reconfiguration request to cancel pending configurations, allowing resources to be recovered and reused rather than wasted on obsolete configuration data.
3Stability of the object's composition
If cell change configuration information is fixed after sending to target node, then configuration stability is improved, but configuration updates become impossible
Solution Approach 1:
The patent implements a dynamic reconfiguration system where conditional handover configuration information can be updated after initial setup. The source node maintains the ability to modify or cancel configurations through standardized message exchange with the target node, ensuring both stability during normal operation and flexibility when changes are needed.
