发明名称 WIRELESS COMMUNICATION SYSTEM, SERVE AND BASE STATION
摘要 When a TCP packet communication acceleration technique is applied to a wireless communication network, an acceleration effect is determined according to various pieces of information in real time, and acceleration control is dynamically performed to efficiently accelerate the communication by the use of the TCP of a wireless terminal present in the wireless communication network. A wireless communication system including at least one wireless terminal and at least one base station that communicates with the wireless terminal further includes an information collection server that collects various pieces of information from the base station and the wireless terminal. The base station includes a packet acceleration unit that accelerates a TCP packet communication, and the information collection server determines whether to accelerate the base station from the various pieces of information, or not, and controls the acceleration of the base station on the basis of its determination result.

主权项 1. A wireless communication system, comprising: a server having a server table that stores measurement information including network communication quality information, wireless communication quality information, and a measured throughput, an acceleration ratio, and a file size; and a base station that starts or stops acceleration processing of a packet communication under a control from the server, wherein upon receiving a packet communication start notice and a file size from a wireless terminal in a state where the acceleration processing of the base station stops, the server transmits a notification start notice to the base station, the base station notifies the server of notification information including network communication quality information and wireless communication quality information, the server calculates an acceleration ratio average indicative of an average of a plurality of acceleration ratios on the basis of a predetermined policy according to the notification information, the file size, and information stored in advance in the server table, performs acceleration determination for starting or stopping the acceleration processing of a packet communication of the wireless terminal according to the acceleration ratio average, and transmits an acceleration start request and an information acquisition start notice to the base station when it is determined that the acceleration processing starts, and the base station starts the acceleration processing of the packet communication of the wireless terminal, and measures and stores measurement information including the network communication quality information, the wireless communication quality information, and the measured throughput at every predetermined time interval, upon receiving a packet communication end notice from the wireless terminal, the server transmits an acceleration stop request and an information acquisition end notice to the base station, the base station stops the acceleration processing of the packet communication of the wireless terminal, terminates the measurement of the measurement information, and transmits the plurality of measurement information measured during the acceleration processing to the server, and the server calculates a theoretical throughput from the network communication quality information on the basis of the plurality of measurement information, divides the measured throughput by the theoretical throughput to obtain the acceleration ratio, and stores the measurement information, the acceleration ratio, and the file size in the server table at the every predetermined time interval.
