Conditional Mobility Execution Control in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling conditional mobility procedures in multi-connectivity scenarios, particularly in 5G NR and E-UTRA networks, face challenges in efficiently managing sequential execution of mobility procedures due to dependencies between configurations and limitations in handling delta and full configurations, leading to potential handover failures and interruptions.
Innovation Solution
An apparatus and method for controlling the sequential execution of conditional mobility procedures, allowing for the simultaneous evaluation and execution of CHO and CPC commands based on specific configuration dependencies, with mechanisms to handle delta and full configurations, and ensuring compatibility with UE capabilities, thereby enabling coexistence and reliable handover operations.

Engineering Contradiction Analysis
1Productivity
If conditional mobility procedures are executed simultaneously, then handover efficiency is improved, but configuration conflicts and execution failures occur
Solution Approach 1:
The patent introduces a preliminary evaluation phase where the UE assesses whether simultaneous execution of conditional mobility procedures is feasible before actually executing them. The UE evaluates configuration dependencies and determines a safe execution order, preventing conflicts before they occur. This preliminary action enables efficient parallel processing when safe, while avoiding execution failures when conflicts exist.
2Reliability
If sequential execution control is implemented, then configuration conflicts are avoided, but handover execution time increases
Solution Approach 1:
The patent implements a dynamic execution control mechanism where the UE continuously monitors configuration dependencies and adjusts the execution strategy in real-time. When configurations are independent, the UE executes procedures in parallel to minimize time loss. When dependencies are detected, the UE dynamically switches to sequential execution to maintain configuration consistency. This dynamic adaptation optimizes both reliability and execution time based on actual system state.
3Reliability
If dependency checking is performed between configurations, then execution correctness is improved, but processing complexity increases
Solution Approach 1:
The patent enables the UE to autonomously perform dependency checking and execution order determination without requiring complex external control mechanisms. The UE independently evaluates configuration dependencies, determines safe execution sequences, and controls the mobility procedures themselves. This self-service approach improves execution correctness while avoiding the added complexity of external control systems, as the UE leverages its existing processing capabilities.
