A base station transmits data to a client terminal only when an excessive load is not exerted on an internet network

摘要

A radio network communication system includes a server 2021, storing files therein, a client terminal 204 making a request to download a desired file thereto among the files stored in the server 2021 and a base station 2031. The base station 2031 includes a data transceiver which makes radio-communication with the client terminal 204, and which, when the request is made by the client terminal 204, transmits the request to the server and receives all data constituting the desired file, from the server 2021, and a load measurement unit which measures a network load between the client terminal 204 and the base station 2031. The base station 203 divides the received file into sub-files in accordance with the load measured by the load measurement unit, and transmits each of the sub-files to the client terminal 204.
