Leader-Follower Base Station Control With Dynamic Reclassification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In situations where the operation control of follower base station systems is performed based on the degree of operation of leader base station systems, changes in the degree of operation of specific follower base station systems, such as due to increased subscriber numbers in a specific area, can lead to inaccurate operation control, necessitating the removal of these systems from the base station system group.
Innovation Solution
A control system that identifies the degree of correlation between base station systems, classifies them into groups, and removes follower base station systems from these groups when the deviation in their operation ratio exceeds a predetermined condition, using methods such as cross-correlation coefficients and variance analysis.

Engineering Contradiction Analysis
1Productivity
If operation control of follower base station systems is performed based on the degree of operation of leader base station systems, then resource optimization and coordinated control are improved, but accuracy of operation control deteriorates when follower systems experience independent changes such as subscriber number increases
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring the degree of operation of follower base station systems and comparing it with the degree of operation of leader base station systems. When the correlation falls outside the predetermined range, the system detects this deviation and triggers reclassification, ensuring that operation control accuracy is maintained while preserving resource optimization benefits
Solution Approach 2:
The patent makes the base station system group classification dynamic by allowing systems to be reclassified based on changing operational conditions. The classification is not static but adapts in real-time based on the correlation between follower and leader systems, enabling the system to respond to independent changes in follower systems while maintaining overall coordination
2Productivity
If base station systems are grouped by correlation of degree of operation transition, then operation control efficiency is improved, but system complexity increases due to continuous monitoring and classification requirements
Solution Approach 1:
The patent segments the base station system monitoring task by dividing systems into leader and follower roles within groups. This segmentation allows the control system to focus monitoring efforts on key relationships (leader-follower correlations) rather than all possible system interactions, reducing overall system complexity while maintaining control efficiency
Solution Approach 2:
The patent uses parameter changes (specifically the correlation coefficient and predetermined range thresholds) to simplify the classification process. By establishing clear numerical criteria for grouping and reclassification, the system transforms a complex qualitative assessment into a straightforward quantitative comparison, reducing control system complexity
3Measurement precision
If follower base station systems are removed from groups when operation ratio deviation exceeds predetermined conditions, then operation control accuracy is improved, but loss of time occurs due to continuous monitoring and removal operations
Solution Approach 1:
The patent implements periodic monitoring of the degree of operation correlation between follower and leader base station systems. Instead of continuous monitoring, the system checks correlations at regular intervals or when specific triggering conditions occur, reducing time loss while maintaining the ability to detect and respond to deviations that require reclassification

AI summary
An operation control module executes, for each of a plurality of base station system groups, operation control corresponding to a degree of operation of a leader base station system included in the base station system group, with respect to a follower base station system included in the base station system group. A removal module removes, in accordance with a fact that a magnitude of a deviation of a ratio of the degree of operation of a follower base station system included in one of the base station system groups with respect to the degree of operation of a leader base station system included in the base station system group from a given reference ratio has satisfied a predetermined condition, the follower base station system from the base station system group.
