Abstract

A method for downloading non-standard MIME type files onto a terminal including determining whether or not a type of the MIME file is supported by the terminal, and downloading a handler to process the MIME file if the type of MIME file is not supported by the terminal.

Claims

1. A method for downloading a non-standard MIME (Multipurpose Internet Mail Extensions) type application to a terminal comprising:

judging a type of the MIME application from a received descriptor file Uniform Resource Locator (URL);

if the type of the MIME application is a non-standard MIME type as a result of the judgment, determining whether or not a handler for the non-standard MIME type application exists in a memory of the terminal; and

if the handler for the non-standard MIME type application does not exist in the memory of the terminal as a result of the judgment, downloading a handler descriptor file from an external server.

2. The method of claim 1, wherein if the handler for the non-standard MIME type application does not exist, the method further comprises:

sending a prepared request URL to a browser and receiving a handler descriptor file URL from the browser that corresponds to the prepared request URL; and

downloading the handler descriptor file from the external server using the handle descriptor file URL.

3. The method of claim 2, wherein the request URL includes the handler descriptor file URL and data regarding the type of the non-standard MIME application.

4. The method of claim 1, further comprising:

if a handler for the received non-standard MIME type application exists in the memory of the terminal, using that handler to process contents of the non-standard MIME type application.

5. The method of claim 1, further comprising:

if the type of the MIME application is a standard MIME type application as a result of the judgment, downloading the descriptor file.

6. The method of claim 1, wherein the browser receives the descriptor file URL from a browser page based on a request.

7. The method of claim 1, further comprising:

downloading a handler from an external server based on the downloaded handler descriptor file.

8. The method of claim 7, further comprising storing the downloaded handler in the memory of the terminal.

9. A system for downloading a non-standard MIME (Multipurpose Internet Mail Extensions) type application onto a terminal, comprising:

a terminal including a browser, a java application manager (JAM) and a memory;

a browser page for transmitting a descriptor file Uniform Resource Locator (URL) to the browser;

a descriptor file server for transmitting a descriptor file corresponding to the descriptor file URL to the JAM;

a handler descriptor file server for transmitting a handler descriptor file to the JAM;

a handler server for transmitting a handler to the JAM; and

a contents server for transmitting contents of the MIME application to the JAM.

10. The system of claim 9, wherein the terminal communicates with the browser page, the descriptor file server, the contents server, the handler descriptor filer server, and the handler server using a HyperText Transfer Protocol (HTTP).

11. The system of claim 9, wherein the browser page, the descriptor filer server, the contents server, the handler descriptor filer server, and the handler server are a single unit or are separate units.

12. The system of claim 9, wherein the JAM searches the memory of the terminal for a handler that can process the non-standard MIME application and downloads a handler from an external handler server if the handler is not stored in the memory of the terminal.

13. A method for downloading non-standard MIME (Multipurpose Internet Mail Extensions) type application onto a terminal, comprising:

determining whether or not a type of MIME application is supported by the terminal; and

downloading a handler to process the MIME application if the type of the MIME application is not supported by the terminal.

14. The method of claim 13, wherein downloading the handler comprises:

downloading the handler from an external server having handlers to process the non-supported MIME type application if a handler to process the non-supported MIME application does not exist in a memory of the terminal.

15. The method of claim 13, wherein downloading the handler comprises:

retrieving a handler description file URL from an external handler descriptor file server; and

downloading the handler from the external server based on the handler descriptor file URL.

16. The method of claim 13, wherein downloading the handler comprises:

prompting a user of the terminal to acknowledge the handler be downloaded prior to downloading the handler.

17. The method of claim 13, further comprising:

downloading contents of the non-supported MIME type.

18. The method of claim 17, wherein downloading the contents comprises:

prompting a user of the terminal to acknowledge downloading of the contents prior to downloading the contents.

19. The method of claim 13, wherein determining whether or not the type of MIME application is supported comprises:

reading a header file of an HTTP message.
