Conditional Handover Connectivity Configuration Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conditional handover procedures in dual connectivity wireless communication systems face challenges in reducing signaling overhead and improving reliability and throughput due to unpredictable radio conditions at the time of handover execution.
Innovation Solution
Implementing a conditional handover procedure that allows a client node to select between different connectivity configurations based on predefined conditions, including single or dual connectivity options with target master and secondary nodes, to optimize handover execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conditional handover procedures are implemented in dual connectivity systems, then reliability and throughput are improved, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by configuring multiple conditional handover connectivity configurations in advance before handover execution. The client node receives and stores multiple connectivity configurations (single connectivity and dual connectivity options) beforehand, along with their associated trigger conditions. When handover is needed, the client node simply evaluates which pre-configured option to execute based on current radio conditions, avoiding the need for extensive real-time signaling negotiations and improving both reliability and reducing signaling overhead.
2Adaptability or versatility
If multiple conditional handover connectivity configurations are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the connectivity configuration selectable and changeable based on real-time radio conditions. The client node dynamically evaluates trigger conditions associated with each conditional handover connectivity configuration and selects the appropriate configuration to execute. This dynamic selection mechanism provides adaptability to different network scenarios while keeping the device complexity manageable through automated condition-based decision logic rather than requiring complex manual configuration management.
