Shared Radio Unit Band Allocation With Local Effect Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems using 5G technology, the high-frequency radio waves necessitate dense placement of base station devices, leading to increased information consolidation and transfer in communication control devices, which can overwhelm the network.
Innovation Solution
A communication system with a common control device and individual control devices that calculate and optimize band allocation across shared radio units (RUs) among multiple mobile network operators (MNOs), reducing information transfer by consolidating table information on effect evaluation values rather than raw reception quality data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If base station devices are arranged densely to support 5G high-frequency radio waves, then communication coverage and system capacity are improved, but information consolidation and transfer in communication control devices increase, overwhelming the network
Solution Approach 1:
The patent extracts only the essential effect evaluation values from raw reception quality data. Instead of transferring complete reception quality information for all cells, the system calculates and transfers only the derived effect evaluation values that indicate the impact of band changes, dramatically reducing information volume while preserving the necessary control functionality
Solution Approach 2:
The patent inverts the traditional control information flow by having individual control devices calculate effect evaluation values locally and transfer only these compressed results to the common control device, rather than transferring all raw measurement data for centralized processing. This reversal of the information processing sequence reduces network load
2Measurement precision
If raw reception quality data is transferred to the common control device for band allocation optimization, then accurate band allocation decisions are achieved, but network information transfer volume increases significantly
Solution Approach 1:
The patent transforms the raw reception quality data into a different parameter form - the effect evaluation value. This parameter transformation compresses the information while retaining the essential meaning needed for band allocation decisions, achieving both accuracy and reduced data volume
Solution Approach 2:
The effect evaluation value acts as an intermediary between raw reception quality data and band allocation decisions. Instead of directly using large volumes of raw data or making decisions without sufficient information, the system introduces this intermediate calculated parameter that bridges the gap between detailed measurements and control actions

AI summary
A communication system includes a plurality of first communication control devices that are arranged in association with a plurality of operators, and a second communication control device that is connected to the first communication control devices. The first communication control device calculates an effect evaluation value in a case where bands used by an operator of subject are increased and reduced and transmits information containing the effect evaluation value to the second communication control device. The second communication control device specifies a combination of radio devices and a combination of operators that maximize a value of change in a case where each operator changes the used bands of the radio devices and instructs the first communication control devices corresponding to the operators of the specified combination to increase and reduce the used bands of the radio devices of the specified combination.
