Base station equipment, control method, and program for performing communication control based on communication service requests.

Abstract

To make it possible to perform communication control that takes into account multiple types of required quality.SOLUTION: A base station device for providing wireless communication services with throughput and delay requirements to a terminal device obtains a first measurement value regarding throughput and a second measurement value regarding delay in communication with the terminal device, sets an allowable delay and an allowable error rate for wireless communication based on whether the first measurement value exceeds a first requirement value regarding throughput and the second measurement value is below a second requirement value regarding delay, and controls communication with the terminal device based on the allowable delay and the allowable error rate.SELECTED DRAWING: Figure 5
