Line quality measurement method and line quality measurement system

Abstract

【Problem】To realize measurement of line quality with reduced influence due to environmental differences of connection destinations. 【Solution】A line quality measurement method for measuring the line quality when a communication device connected in a local network capable of communicating with a wide area network uses the wide area network, the method including: a measurement communication process in which a measurement terminal, which is a device for performing measurement communication for measuring line quality and is a communication device directly communicably connected to an intermediary device that mediates communication between the wide area network and the local network, performs measurement communication at a predetermined frequency; a measurement result transmission process in which the communication result of the measurement communication is transmitted as a line quality measurement result to a collection server; and a result storage process in which the line quality measurement results transmitted from a plurality of measurement terminals are stored in the collection server. 【Selected Drawing】Figure 1
