Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems do not support simultaneous configuration of conditional handover and conditional PSCell addition/change in dual connectivity scenarios, limiting mobility management reliability and accuracy.
Innovation Solution
A method and device for managing terminal mobility that allows simultaneous configuration and execution of conditional handover and conditional PSCell addition/change based on pre-configured conditions, using information sent by a network device and executed by a terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conditional handover and conditional PSCell addition/change are configured separately, then the system structure is simple, but the mobility management reliability and accuracy are limited
Solution Approach 1:
The patent combines conditional handover and conditional PSCell addition/change into a single unified configuration structure. The network device can simultaneously configure both conditional handover parameters and conditional PSCell addition/change parameters, allowing the terminal to execute both mobility procedures based on the same execution condition. This merging approach improves mobility management reliability and accuracy while avoiding the limitations of separate configurations.
2Measurement precision
If conditional handover and conditional PSCell addition/change are configured simultaneously, then the mobility management accuracy is improved, but the configuration and execution complexity increases
Solution Approach 1:
The patent segments the conditional mobility configuration into distinct but coordinated components: conditional handover configuration and conditional PSCell addition/change configuration. Each component has its own parameters and execution logic, but both are governed by the same execution condition. This segmentation allows for precise control and independent optimization of each mobility procedure while maintaining overall coordination through the unified execution condition framework.
3Reliability
If separate conditional mobility configurations are used, then the execution logic is simple, but the mobility management robustness is reduced
Solution Approach 1:
The patent implements a feedback mechanism where the terminal evaluates the execution condition and selectively executes the appropriate conditional mobility procedure (conditional handover, conditional PSCell addition, or conditional PSCell change) based on the current network state and measurement results. The network device receives feedback information from the terminal and can adjust the configuration accordingly. This feedback loop enhances mobility management robustness by enabling adaptive decision-making while maintaining clear execution logic through the unified condition-based framework.
