Abstract

A communication system includes a first network on which a file server and an access point are connected via a first communication link and a second network on which the access point and a terminal are connected via a second communication link. The terminal establishes a connection with the access point to access the file server. The file server stores a file to be downloaded. The terminal accesses the file server through the access point to request the file. The terminal then selects a download process from one of a foreground process, background process and postponement process, and executes the download process to download the file from the file server.

Claims

1. In a communication system including a first network on which a file server and an access point are connected via a first communication link and a second network on which the access point and a terminal are connected via a second communication link, wherein the terminal establishes a connection with the access point to access a file on the file server, a download control method comprising:

accessing from the terminal to the file server through the access point to request the file;

selecting a download process from one among a foreground process, a background process, and a postponement process each available to download the file from the file server to the terminal; and

executing the download process to download the file from the file server to the terminal.

2. The method according to claim 1, further comprising:

accepting an instruction from the terminal; and

selecting the download process according to the instruction.

5. The method according to claim 1, further comprising:

selecting the download process based on an urgent level of the file.

6. The method according to claim 1, further comprising:

notifying a size of the file from the file server to the terminal; and

selecting the download process depending on the size of the file.

7. The method according to claim 1, further comprising:

determining a download process from one of a foreground process, background process and postponement process by the file server; and

instructing the terminal to execute the download process for a file to be downloaded to the terminal.

9. The method according to claim 1, wherein:

determining a download process from one of a foreground process, background process and postponement process by the access point; and

instructing the terminal to execute the download process for a file to be downloaded to the terminal, which is stored in the file server.

11. The method according to claim 1, further comprising:

determining whether or not a communication between the terminal and an external computer goes through a screening server.

12. A communication system comprising:

a first network on which a file server and an access point are connected via a first communication link, the file server storing a file; and

a second network on which the access point and a terminal are connected via a second communication link, wherein the terminal establishes a connection with the access point to access the file server, and

wherein the terminal accesses the file server through the access point to request the file, selects a download process from one of a foreground process, background process and postponement process, and executes the download process to download the file from the file server.

13. The system according to claim 12, wherein the terminal forcibly selects the download process according to a user instruction.

16. The system according to claim 12, wherein the terminal selects the download process based on an urgent level of the file.

17. The system according to claim 12, further comprising:

a screening server configured to protect the terminal from acquiring a virus during at least the background process.

18. The system according to claim 12, wherein:

the file server notifies a size of the file to the terminal; and

the terminal selects the download process depending on the size of the file.

19. The system according to claim 12, wherein:

the file server determines a download process from one of a foreground process, background process and postponement process; and

the file server instructs the terminal to execute the download process for a file to be downloaded to the terminal.

21. The system according to claim 12, wherein:

the access point determines a download process from one of a foreground process, background process and postponement process; and

the access point instructs the terminal to execute the download process for a file to be downloaded to the terminal, which is stored in the file server.

23. The system according to claim 12, wherein the terminal determines whether or not a communication between the terminal and an external computer goes through a screening server.
