Cell Load Imbalance Optimization via Timing Advance Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication networks using multiband networking, load imbalances between cells covered by the same network lead to poor user experience due to uneven data transmission speeds, as most users access a single cell while a few access others, necessitating optimization to distribute load more evenly.
Innovation Solution
A method to determine and adjust the load of cells with the highest and lowest network load rates by calculating a target offset parameter based on timing advance and sampling points, allowing user equipment to reselect or switch cells to balance the load, thereby optimizing unbalanced loads within the same network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiband networking is used to improve network capacity, then network coverage and user capacity are improved, but load imbalance between cells occurs causing poor user experience
Solution Approach 1:
The patent changes the parameter of cell selection by introducing a target offset parameter that adjusts the predetermined index based on timing advance and sampling point differences. This parameter modification redirects user equipment from overloaded cells to underloaded cells, balancing the load distribution across multiple cells while maintaining network capacity
2Ease of operation
If user equipment accesses the same cell, then connection simplicity is maintained, but load concentration occurs reducing data transmission speed
Solution Approach 1:
The system enables user equipment to automatically select optimal cells based on the target offset parameter without manual intervention. The user equipment self-adjusts its cell selection by comparing timing advance and sampling points, distributing connections across multiple cells to prevent load concentration while maintaining simple automatic connection behavior
3Productivity
If automatic optimization is implemented, then load balancing is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the network device calculates the target offset parameter based on timing advance and sampling point differences, then uses this parameter to guide user equipment cell selection. This feedback loop automatically balances load across cells through parameter adjustment rather than complex system reconfiguration, improving load balancing while controlling system complexity
