A service control device is connected to a plurality of communication terminals with a multitasking ability of executing a plurality of application programs. Each communication terminal detects a usage status including a task status, a foreground ratio, and an operation frequency for each application program, thus producing service usage information reflecting a service usage history and a degree of user's concentration. The service control device determines a priority on communication terminals based on service usage information, thus generating service control information. The service control information is provided to control resource allocation per each communication terminal. A band allocation control procedure is implemented based on service control information so that each communication terminal may arbitrarily download a plurality of content data in a serial manner or in a parallel manner. Thus, it is possible to maintain a high level of user satisfaction in communication services.
