Service channel management method, management device and system

The invention discloses a method for managing a service channel. The method can be applied to a cloud system (a cloud communication platform CPaaS). The method comprises the steps that a plurality of first service channels are acquired, and the service capability of each first service channel is matched with a service quality requirement; and determining a quality prediction result of each first service channel in a second period according to the service quality parameter of each first service channel in the first period, the service quality parameter being used for describing the service quality of the corresponding first service channel in the first period, and the second period being an unstarted period after the first period. According to the scheme provided by the invention, the cloud communication platform can predict the service quality of the unstarted period according to the service quality parameter of the historical period, and does not need to sense the problem of the service channel after the fault of the service channel, thereby improving the timeliness of monitoring the service channel and the reliability of the service channel.
