Wireless Load Balancing via Secondary Base Station Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current load balancing methods in wireless communication, particularly in 5G networks, introduce significant delay and signaling overhead due to the complex interaction between master base stations and secondary base stations, which is inefficient for services requiring low latency.
Innovation Solution
A method and apparatus where a master base station determines a load balancing group of secondary base stations and sends grouping information, allowing these secondary base stations to directly perform load balancing with each other without the master base station, thereby reducing delay and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If load balancing is performed through master base station coordination, then load distribution among secondary base stations is achieved, but signaling overhead and delay increase significantly
Solution Approach 1:
The patent segments the load balancing process into two parts: (1) master base station determines load balancing groups and configures secondary base stations with group information, and (2) secondary base stations autonomously perform load balancing within their groups. This segmentation reduces the need for continuous master base station involvement, thereby reducing signaling overhead and delay while maintaining load balancing effectiveness.
Solution Approach 2:
The master base station performs preliminary action by determining load balancing groups and configuring secondary base stations with group information in advance. This preliminary configuration enables secondary base stations to autonomously perform load balancing without requiring real-time coordination with the master base station, thus reducing operational delay and signaling overhead.
2Extent of automation
If master base station dominates load balancing coordination, then centralized control is maintained, but signaling overhead increases
Solution Approach 1:
The patent segments control authority by allowing secondary base stations to autonomously perform load balancing within their configured groups, rather than requiring all decisions to pass through the master base station. This reduces the volume of signaling messages needed while maintaining centralized oversight through the initial group configuration.
Solution Approach 2:
Secondary base stations are empowered to self-manage load balancing within their groups by autonomously selecting target base stations and executing load transfer based on local conditions. This self-service capability eliminates the need for continuous master base station coordination, significantly reducing signaling overhead while maintaining effective load distribution.

AI summary
A method and apparatus for load balancing. The method executed by a master base station for load balancing comprising: determining a load balancing group, wherein the load balancing group includes a plurality of secondary base stations; and sending a grouping information about the load balancing group to each secondary base station of the load balancing group. The method executed by a secondary base station of a load balancing group for load balancing comprising: receiving a grouping information about the load balancing group from a master base station; exchanging the load information with other secondary base stations of the load balancing group; selecting a target secondary base station from the other secondary base stations according to the load information of other secondary base stations; and forwarding at least a portion of load of the secondary base station to the target secondary base station.
