摘要： Congestion determination of a base station is not communicated based on a theoretical traffic amount, but higher accurate congestion determination is communicated based on an effective traffic amount which can be transmitted and received by the base station under an environment in which the base station is deployed.

摘要： A monitoring system comprises: a measurement unit; and an analysis unit, wherein the measurement unit measures traffic information relating to messages inputted to a device to be monitored and messages outputted from the device to be monitored, and wherein the analysis unit calculates one or more indices on the basis of a prescribed relational expression and the measured traffic information, and detects that a specific change in state has occurred in the device to be monitored on the basis of the indices or a comparison between a change in the indices and a threshold.

摘要： A communication system includes a mobile terminal, a base station, a first gateway device, a second gateway device, a flow measurement server, a quality management server, and an operational terminal. A predetermined flow is extracted by a quality management server, and the extracted flow is summarized for each communication path. A distribution of the communication quality of the flow for each communication path is displayed on a display unit of the operational terminal.

摘要： A monitoring device executes: aggregating a number of messages for each type of message transmitted or received at nodes using test results; classifying the respective messages into either an original message that serves as an origin among messages transmitted and received by a system to be monitored, or a generated message that is generated in the system when the original message is transmitted to any of the plurality of nodes; analyzing a relationship between the original message and the generated message on the basis of a number of messages classified as the original message and a number of messages classified as the generated message, thereby creating a matrix indicating the relationship between the original message and the generated message; and determining that the system has undergone a failure if a value of an element inside the matrix is outside of a normal range.

摘要： A communication caused by applications that cannot be managed by an operator is operated on a mobile network, and is difficult to control. Therefore, burst traffic induced by the applications needs to be effectively detected, restricted, and controlled. A system has a terminal that monitors an update status of applications on a mobile network, periodically monitors the update status of the applications, extracts traffic of the applications from packets transmitted through the mobile network, summarized a traffic volume induced by the applications to detect the burst traffic generated when any application is updated, and controls the traffic of the applications when the burst is generated.
