  • Publication number: 20210168051
    Abstract: Included are a communication quality requirement derivation unit that derives, for a specific service session between a server and a terminal, a communication quality requirement to be satisfied between the server and the terminal based on a requested quality of experience of the specific service session; a monitoring unit that monitors a communication quality of the specific service session between the server and the terminal; a determination unit that determines whether the communication quality of the specific service session satisfies the communication quality requirement derived for the specific service session; and a control unit that controls, when the communication quality of the specific service session does not satisfy the communication quality requirement derived for the specific service session, a communication route used for the specific service session between the server and the terminal so as to satisfy the communication quality requirement.

  • Publication number: 20210120067
    Abstract: A quality prediction apparatus includes a first acquisition unit acquiring a first throughput for an access network of a terminal from the terminal, the terminal acquiring video data in a divided state from a plurality of video streaming servers, a second acquisition unit acquiring a second throughput for a core network to which the plurality of video streaming servers connect, the terminal being to acquire the video data from one of the video streaming servers, and a prediction unit selecting smaller one of the first throughput and the second throughput as a prediction value of a throughput for the video data to be acquired, and therefore, an efficient prediction of the throughput for the video data streaming can be enabled.
