NR-DC UE Inactivity Timer Transfer for Coordinated Resource Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In NR-DC systems, the transfer of inactive time of user equipment (UE) is not efficiently managed during bearer changes, leading to increased power consumption and waste of radio resources due to the lack of synchronization of UE inactivity timers across different nodes.
Innovation Solution
Implement a resource management method that transfers and synchronizes the continued inactive time of UE across nodes by subtracting the sum of inactive times at all previous nodes from a total preset inactive time duration, allowing timely release of resources when the remaining inactive time is exhausted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the inactive time of UE is not transferred and synchronized across nodes during bearer changes, then the management of UE inactivity is simpler at each individual node, but the radio resources are wasted and power consumption increases due to lack of coordination
Solution Approach 1:
The patent introduces an intermediary mechanism where the source node acts as a coordinator to transfer the continued inactive time parameter to the target node during bearer changes. This intermediary approach allows distributed nodes to maintain simple local logic while achieving system-wide coordination through the transfer of inactivity timing information, thereby reducing power consumption without significantly increasing individual node complexity
Solution Approach 2:
The patent implements a feedback mechanism where the source node provides information about the UE's continued inactive time to the target node during handover. This feedback loop ensures that the target node can make informed decisions about resource allocation and release timing, preventing both premature resource release and unnecessary resource retention, thus optimizing power consumption
2Device complexity
If the inactive time of UE is not transferred across nodes during bearer changes, then the implementation at each node is simpler, but the radio resources are not efficiently released leading to resource waste
Solution Approach 1:
The source node serves as an intermediary that calculates and transfers the continued inactive time parameter to the target node. This allows the target node to maintain simple implementation logic while receiving coordinated information about when to release resources, ensuring efficient radio resource utilization without increasing target node complexity
Solution Approach 2:
The source node performs preliminary calculation of the continued inactive time before the bearer change occurs, and transfers this information to the target node in advance. This preliminary action enables the target node to prepare for timely resource release without needing complex real-time analysis, thus preventing resource waste while maintaining simple node implementation
3Productivity
If the continued inactive time is not transferred from source node to target node, then the handover procedure is simpler, but the resource release timing is inaccurate causing system resource waste
Solution Approach 1:
The patent extracts the continued inactive time parameter from the source node's context and transfers it to the target node during handover. This extraction approach allows the handover procedure to remain relatively simple while ensuring that the critical timing information is preserved and transferred accurately, maintaining both handover efficiency and measurement precision
Solution Approach 2:
The source node creates a copy of the continued inactive time parameter and transfers it to the target node. This copying mechanism ensures that the timing information is accurately replicated without requiring complex synchronization protocols, thus maintaining handover efficiency while achieving precise inactivity time measurement at the target node

AI summary
The present disclosure provides a resource management method, an electronic device and a computer-readable storage medium. The resource management method includes: determining whether remaining inactive time of user equipment (UE) for a target bearer node is exhausted; and in response to that the remaining inactive time of the UE for the target bearer node is exhausted, releasing resources allocated to the UE, the remaining inactive time includes a result of subtracting a sum of continued inactive time of the UE occurred at all nodes from a total preset inactive time duration, the total preset inactive time duration corresponds to the target bearer node.
