Base Station Signal Quality Scoring for Network Traffic Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the transmission of packet signals from multiple base stations to a control station increases network traffic, leading to inefficiencies and higher costs due to the need for aggregating and evaluating call information across multiple base stations, especially when the IP network's circuit speed is low or traffic is heavy.
Innovation Solution
A base station apparatus calculates quality scores for received signals from terminal apparatuses and multicasts these scores to other base stations, allowing only the base station with the highest quality score to transmit the corresponding call information, thereby reducing the number of packet signals transmitted over the network and minimizing traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet signals are transmitted from multiple base stations to the control station, then the quality of call information can be evaluated and the best packet can be selected, but network traffic increases and system efficiency decreases
Solution Approach 1:
The system segments the packet signal transmission process into two stages: first, base stations transmit only quality information (not full packet signals) to neighboring base stations; second, only the base station with the highest quality score transmits the actual packet signal. This segmentation reduces redundant data transmission while maintaining quality evaluation capability.
Solution Approach 2:
Base stations autonomously calculate quality scores for received packet signals and independently determine which signals to transmit, eliminating the need for a central control station to aggregate and evaluate all signals. Each base station serves itself by making local decisions based on quality comparisons with neighboring stations.
2Reliability
If a control station aggregates and evaluates packet signals from multiple base stations, then the best packet can be selected, but system complexity and costs increase
Solution Approach 1:
The invention extracts the packet signal transmission function from the control station and distributes it to individual base stations. Base stations independently evaluate signal quality and make transmission decisions locally, eliminating the need for a complex central control station while maintaining accurate packet selection through distributed quality comparisons.
3Measurement precision
If all base stations transmit packet signals to the control station, then comprehensive quality evaluation is possible, but network traffic and transmission costs increase
Solution Approach 1:
Instead of all base stations transmitting complete packet signals to the control station, only base stations transmit partial quality information to neighboring stations. The transmission action is applied selectively - only the base station with the highest quality score transmits the full packet signal, while others only exchange quality metrics, significantly reducing overall network traffic volume.

AI summary
A quality score calculator calculates first quality information indicating a degree of quality of a signal received from a terminal apparatus. A communication interface acquires second quality information indicating a degree of quality of a signal received by another base station apparatus from the terminal apparatus. A controller compares the first quality information calculated and the second quality information acquired and determines which indicates a higher quality. A communication interface and a wireless transmitter transmit the signal received from the terminal apparatus when it is determined that the quality of the first quality information is higher.
