Title:

QUALITY ESTIMATION SYSTEM, QUALITY ESTIMATION METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2020/141590

Kind Code:

A1

Abstract:

Provided is a quality estimation system that estimates download throughput for a user terminal connected to a wireless network, wherein the system comprises: an acquisition means that acquires, from a plurality of user terminals, at least terminal information, wireless reception quality information, and network quality information; a coefficient derivation means that derives, on the basis of the information acquired by the acquisition means, a coefficient of an estimation expression in which the download throughput is used as a target variable, and at least the wireless reception quality information and network quality information are used as explanatory variables; and an estimation means that uses the estimation expression in which the coefficient is applied to estimate, from measurement data, the download throughput corresponding to the measurement data.
