Conditional Configuration Release for Mobility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as 5G NR, face challenges in optimizing network services and managing mobility effectively, particularly in scenarios involving multiple radio access technologies and cells.
Innovation Solution
The proposed method and apparatus for mobility management in User Equipment (UE) involve receiving conditional configurations from the network for candidate target Primary Cells (PCells) and determining whether execution conditions are met. If satisfied, the UE applies the configuration to switch to the target PCell and decides whether to release associated secondary conditional configurations based on their association.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple conditional configurations are stored for candidate target cells, then mobility management flexibility is improved, but device complexity and memory usage increase
Solution Approach 1:
The patent implements a mechanism where conditional configurations are selectively released after successful handover. When a handover is executed to a target PCell, the associated conditional configuration is released to free up storage resources. This allows the system to maintain multiple configurations for flexibility while managing device complexity through automatic cleanup of used configurations.
2Adaptability or versatility
If conditional configurations are retained after handover, then future handover options are preserved, but memory resources are consumed
Solution Approach 1:
The system releases conditional configurations that have been executed to recover memory resources. The release mechanism is triggered upon successful handover execution, allowing the UE to free up storage space while maintaining the ability to receive and store new conditional configurations as needed for future mobility management.
3Quantity of substance
If all conditional configurations are released after handover, then memory resources are freed, but association information is lost
Solution Approach 1:
The patent implements selective release of conditional configurations based on their execution status. Configurations that have been successfully executed are released to free memory, while the release decision is made intelligently to maintain necessary association information. The system determines whether to release a configuration based on whether it is associated with the executed handover, preserving information needed for future related operations.

AI summary
Methods and apparatuses for mobility management are provided. The method includes receiving, from a network, a first conditional configuration for a candidate target Primary Cell (PCell). The first conditional configuration indicates an execution condition. The method determines whether the execution condition is satisfied and in response to determining that the execution condition is satisfied, applies the first conditional configuration to switch to the candidate target PCell. The method then, after switching to the candidate target PCell, determines whether to release a second conditional configuration, which has been stored at the UE prior to switching to the candidate target PCell, based on whether the second conditional configuration is associated with the first conditional configuration.
