Movable Base Station Positioning for 5G Signal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with many shielding objects, such as distribution centers or exhibition halls, the quality of wireless communication using high-frequency bands like 5G is unstable due to high-frequency radio wave loss and straightness, leading to suboptimal base station positioning and potential communication quality deterioration.
Innovation Solution
A communication system with a control server that selects the movement destination for a movable base station to minimize movement distance while maintaining required communication quality, using a base station position evaluation index to optimize positioning, either by setting a threshold for movement distance or selecting the highest evaluation index within a threshold range.

Engineering Contradiction Analysis
1Reliability
If the movable base station is controlled to move to optimal positions in real time, then communication quality is improved, but the moving time increases and may cause periods of deteriorated quality
Solution Approach 1:
The control server pre-calculates and determines optimal base station positions before movement is needed. By advance computing the positions where the base station should be located based on predicted terminal distributions and shielding object locations, the system ensures that movement can be executed smoothly without causing communication quality deterioration during the transition period.
2Reliability
If the movable base station moves to positions with optimal evaluation indices, then communication quality is improved, but the movement distance increases
Solution Approach 1:
The control server dynamically adjusts the base station position selection criteria by changing parameters such as the evaluation index threshold and movement distance constraints. By modifying these parameters based on current system state, terminal distribution, and shielding object locations, the server optimizes the balance between achieving high communication quality and minimizing movement distance.

AI summary
A communication system including a control server apparatus and a movable base station device, wherein the control server apparatus is configured to select, as a movement destination position of the movable base station device, a position at which a movement distance from a current position of the movable base station device is minimum, among positions at which a base station position evaluation index is equal to or larger than a threshold, or a position at which the base station position evaluation index is maximum, among positions at which the movement distance from the current position of the movable base station device is equal to or smaller than a threshold, and wherein the control server apparatus is configured to perform control to move the movable base station device to the movement destination position.
