Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load balancing methods for inter-frequency cells in LTE networks fail to achieve dynamic balancing in various load situations, leading to uneven user distribution and potential load accumulation.
Innovation Solution
A method and apparatus for centralized load assessment and active load balancing among co-coverage inter-frequency cells within a base station, involving the determination of an expected serving cell based on overall load data, and dynamic handover policies to balance loads and users across cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users or services are balanced among a plurality of cells that have different frequencies, then user experience is improved and dynamic adjustment can be performed in various load situations, but in certain situations, the dynamic balancing requirements in various load situations are not satisfied
Solution Approach 1:
The patent implements dynamic load balancing by continuously monitoring load conditions of inter-frequency cells and adjusting user distribution in real-time. The system dynamically changes handover policies based on current load states, enabling the network to adapt to varying load situations while maintaining effective load balancing across all conditions.
2Adaptability or versatility
If centralized load assessment and active load balancing is implemented among co-coverage inter-frequency cells, then dynamic balancing is achieved in various load situations, but system complexity increases
Solution Approach 1:
The patent merges load assessment and load balancing functions into a unified centralized system. By combining these previously separate functions, the system achieves dynamic balancing across inter-frequency cells while reducing overall system complexity through integrated control and coordinated operation.
3Productivity
If load balancing is implemented across all inter-frequency cells, then rational load and user distribution is achieved, but control and coordination overhead increases
Solution Approach 1:
The patent implements preliminary load assessment and handover policy configuration to prevent load accumulation before it occurs. By proactively evaluating load conditions and pre-configuring appropriate handover policies, the system achieves efficient load distribution while minimizing the time required for reactive control and coordination.

AI summary
Disclosed are a load balancing method, apparatus and device, and a storage medium. The method comprises: when a user accesses or switches to the current cell in a co-coverage different-frequency cell group in the same base station, determining whether the current cell is an expected serving cell that satisfies a pre-set load balancing condition; and according to a determination result, balancing the load of the co-coverage different-frequency cell group.
