Cell Management Configuration for Conditional Handover in Multi-Cell Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell management technologies are not applicable to scenarios involving multiple cells, such as dual connectivity and carrier aggregation, as they lack a method for conditional handover between cells, leading to inefficient resource utilization and potential communication performance issues.
Innovation Solution
A cell management method that involves receiving configuration information from a network side device, which includes triggering conditions for multiple cells, allowing the terminal to manage and perform conditional handovers based on signal quality and resource availability, ensuring active cells are maintained for optimal communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conditional handover is applied only to random access technology, then the handover process is simple, but it cannot handle multi-cell connection scenarios like dual connectivity and carrier aggregation
Solution Approach 1:
The patent extends the conditional handover mechanism from random access technology to general cell management scenarios, making it universally applicable to both single-cell and multi-cell connection scenarios including dual connectivity and carrier aggregation. The triggering condition group can be configured for different cells, enabling the terminal to perform conditional handovers in diverse network topologies.
Solution Approach 2:
The patent divides the cell management into separate triggering conditions associated with different cells. Each cell can have its own triggering conditions independently configured, allowing granular control over handover decisions in multi-cell scenarios without overwhelming complexity.
2Loss of energy
If the terminal manages multiple cells without conditional handover, then resource utilization is inefficient, but implementing conditional handover increases management complexity
Solution Approach 1:
The network side device pre-configures triggering conditions for multiple cells before the terminal needs to make handover decisions. These pre-configured conditions include measurement thresholds and other parameters that the terminal uses to evaluate candidate cells, eliminating the need for real-time complex calculations and reducing resource wastage.
Solution Approach 2:
The terminal continuously monitors cell conditions and compares them against the pre-configured triggering conditions. When a cell meets the triggering conditions, the terminal performs conditional handover. This feedback mechanism ensures resources are allocated efficiently based on actual channel quality while maintaining manageable complexity through automated decision-making.
