Abstract
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.
Claims18
A communication system comprising:
- a mobile terminal communicating over a network with a server;
- a flow measurement server between the mobile terminal and the server;
- a quality management server coupled to the flow measurement server,
- wherein the flow measurement server computes a plurality of items of communication quality for each flow based on data flowing between the mobile terminal and the server,
- wherein the quality management server extracts a predetermined flow, summarizes the extracted flow for each communication path, and outputs a distribution of the communication quality for the each communication path, and
- wherein the quality management server extracts the predetermined flow by sorting flows based on an IP address of the server and an L4 port number and selecting a set of the IP address and the L4 port number corresponding to the sorted flows having an average and a variance of the communication quality included in a predetermined range.
