Mobility Parameter Adjustment for Load Balance Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current commercial networks experience ping-pong handover and reselection issues due to manual configuration of timers and thresholds for load balance, leading to instability and unnecessary handovers, affecting network stability and user perception.
Innovation Solution
A method and device that automatically adjust mobility parameters by comparing load conditions and thresholds between cells, selecting target neighboring cells with lower loads, and continuously adjusting mobility parameters until differences meet preset thresholds, thereby preventing ping-pong handovers and reselections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of timers and thresholds is used for load balance, then the load balance function can be implemented, but ping-pong handover and reselection occur causing network instability
Solution Approach 1:
The system performs self-configuration by automatically comparing mobility parameters with load balance thresholds and adjusting parameters autonomously without manual intervention, eliminating the need for operators to manually configure timers and thresholds while preventing ping-pong effects
Solution Approach 2:
The system dynamically adjusts mobility parameters based on comparisons with load balance thresholds, automatically modifying parameters to prevent ping-pong handovers and reselections, thereby maintaining network stability without manual configuration
2Productivity
If mobility parameters are not adjusted, then configuration is simple, but users handover back to high-load cells causing load balance effect to be lost
Solution Approach 1:
The system automatically adjusts mobility parameters by comparing them with load balance thresholds, dynamically changing parameters to prevent users from handovering back to high-load cells, thereby maintaining load balance effectiveness without increasing operational complexity
3Reliability
If automatic adjustment of mobility parameters is implemented, then ping-pong handover is prevented, but adjustment process complexity increases
Solution Approach 1:
The system implements automatic parameter adjustment by comparing mobility parameters with load balance thresholds and modifying parameters as needed, preventing ping-pong handovers through a relatively simple comparison and adjustment mechanism that does not significantly increase system complexity
Solution Approach 2:
The system uses feedback from threshold comparisons to automatically adjust mobility parameters, creating a closed-loop control mechanism that prevents ping-pong handovers while maintaining relatively simple system architecture through straightforward comparison logic
