Base Station Control for Dynamic Service Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to provide efficient and cost-effective communication services for IoT and connected cars with a limited number of base stations, especially in areas requiring high coverage and where high-frequency bands or restricted service cell sizes are used, leading to high installation costs.
Innovation Solution
A base station control apparatus that acquires the service provision state and instructs base stations on whether to provide services based on a service coverage ratio for each road section, optimizing service coverage and reducing power consumption by selectively suspending or starting services as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations are installed densely to achieve high service coverage for moving objects, then service coverage is improved, but installation cost and device quantity increase
Solution Approach 1:
The patent implements dynamic service provision where base stations can switch between service provision and suspension states based on real-time conditions. The control apparatus monitors service coverage ratios and dynamically adjusts base station operations to maintain required coverage while minimizing the number of active base stations, thus resolving the contradiction between coverage reliability and quantity of base stations.
Solution Approach 2:
The system changes the operational state parameter of base stations (from always-on to selectively-on) based on service coverage requirements. By controlling whether base stations provide services or suspend services according to calculated coverage ratios, the system maintains adequate coverage with fewer active base stations, addressing the contradiction between coverage and quantity.
2Reliability
If base stations operate continuously to maintain service availability, then service reliability is improved, but power consumption increases
Solution Approach 1:
Instead of continuous operation, the patent implements periodic service provision where base stations alternate between providing services and suspending services. The control apparatus determines suspension based on service coverage ratios, creating a periodic pattern of operation that maintains service availability when needed while reducing power consumption during suspension periods.
Solution Approach 2:
The system dynamically adjusts base station operational states based on real-time service coverage conditions. Base stations transition between active and suspended states according to calculated coverage ratios, creating a dynamic power management system that balances service availability with power consumption reduction.
3Reliability
If service coverage ratio is increased to ensure adequate service provision, then service quality is improved, but the number of active base stations must increase
Solution Approach 1:
The control apparatus calculates service coverage ratios based on base station locations and service areas, then uses this feedback information to determine whether base stations should provide or suspend services. This closed-loop feedback mechanism ensures that the service coverage ratio requirement is met while optimizing the number of active base stations through intelligent control decisions.
Solution Approach 2:
The system uses service coverage ratio as a control parameter to adjust the operational state of base stations. By changing the operational parameter (service provision vs. suspension) based on the calculated coverage ratio, the system maintains required service quality while minimizing the number of active base stations.

AI summary
A base station control apparatus includes a part that acquires a provision state of a predetermined service by one or more base stations in a service target area; and a part that instructs the one or more base stations whether or not to provide the predetermined service based on a service coverage which indicates a ratio of one or more areas in which the predetermined service is provided by the one or more base stations for each road section included in the service target area.
