Autonomous Mobility Configuration Release in Wireless Handovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conditional handover configurations in wireless communication systems result in significant signaling overhead due to the need for multiple cell configurations, which increases the complexity and resource consumption during mobility operations.
Innovation Solution
A wireless device autonomously releases mobility configurations related to target cells when measurement results satisfy pre-defined leaving conditions, reducing the need for network signaling and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conditional handover configurations are provided for multiple target cells, then handover robustness and service availability are improved, but signaling overhead and system complexity increase significantly
Solution Approach 1:
The network pre-configures conditional handover parameters for multiple potential target cells before handover is needed. The wireless device stores these configurations and automatically applies them when measurement conditions are met, eliminating the need for real-time network signaling during actual handover execution.
Solution Approach 2:
The wireless device autonomously monitors measurement conditions and independently executes handover to pre-configured target cells without requiring continuous network control or acknowledgment signals, thereby reducing signaling overhead while maintaining handover reliability.
2Reliability
If conditional handover configurations are provided for multiple target cells, then handover robustness is improved, but resource consumption during mobility operations increases
Solution Approach 1:
Handover configurations including target cell parameters, measurement thresholds, and execution conditions are pre-configured and cached in the wireless device before mobility events occur. This eliminates the need for repeated resource-intensive signaling exchanges during actual handover execution.
Solution Approach 2:
The wireless device autonomously evaluates measurement conditions against pre-configured parameters and self-executes handover decisions without requiring continuous network interaction, thereby reducing real-time computational and signaling resource consumption while maintaining robust handover performance.

AI summary
A method and apparatus for releasing a mobility configuration without a signal from a network in a wireless communication system is provided. A wireless device receives, from a serving cell, a mobility configuration related to a target cell, wherein the mobility configuration includes a specific identity. A wireless device detects that measurement result of the target cell satisfies a leaving condition related to the specific identity. A wireless device releases, autonomously, the mobility configuration related to the target cell based on the detection.
