Conditional Handover Identifier Mapping for MR-DC Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently managing conditional handover processes in Multi-RAT Dual Connectivity (MR-DC) scenarios, particularly in evaluating and executing nested conditional primary secondary cell changes without decoding nested configurations, which can lead to incorrect execution of conditional configurations.
Innovation Solution
The proposed solution involves generating and sending identifiers that map measurement configurations in the source configuration to conditional primary secondary cell changes in the target configuration, allowing the user equipment to evaluate and execute these changes without unpacking nested configurations, using unique identifiers and reporting configurations to determine when to execute the conditional handover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nested conditional configurations are decoded and executed in current communication systems, then the handover process can be completed, but the complexity of configuration management increases and execution accuracy decreases due to nested structure difficulties
Solution Approach 1:
The patent segments the nested conditional configuration into separate, independent configuration elements. Instead of decoding complex nested structures, the system uses individual configuration objects with unique identifiers that reference measurement results. This segmentation simplifies configuration management and reduces execution errors by eliminating the complexity of nested decoding while maintaining the conditional handover functionality.
2Reliability
If measurement configurations are tightly coupled with conditional handover execution, then accurate handover decisions can be made, but the flexibility and reusability of measurement configurations decrease
Solution Approach 1:
The patent introduces an intermediary mechanism using unique identifiers that act as references between measurement configurations and conditional handover executions. The identifier serves as a mediator that links the measurement result to the corresponding conditional configuration without tight coupling. This allows measurement configurations to be reused across multiple conditional handover scenarios while maintaining accurate decision-making through the identifier reference.
3Productivity
If conditional handover configurations are sent and processed in current systems, then handover can be executed, but processing time increases due to nested configuration decoding requirements
Solution Approach 1:
The patent applies preliminary action by pre-configuring measurement objects and assigning unique identifiers before the conditional handover execution. The measurement configurations are prepared in advance with their identifiers, eliminating the need for complex nested decoding during the actual handover process. This preliminary setup reduces processing time significantly while maintaining the accuracy of handover decisions.

AI summary
An apparatus includes means for generating an identifier for a user equipment, wherein the identifier provides a mapping between a measurement configuration in a source configuration of the user equipment and a configuration of a conditional primary secondary cell change to be executed by the user equipment at a target configuration; and means for sending the identifier, the measurement configuration, and the configuration of the conditional primary secondary cell change to the user equipment.
