Abstract

A system for enhancing network-browsing speed by setting a proxy server on a handheld device comprises a browser operating on the handheld for sending a request for requesting a message including at least one image from a website, receiving a response in response to the request, a proxy server including a cache for processing the request and the response and caching the image included in the response, a wireless network communicably linked to the proxy server, Mobile Data Service (MDS) gateway communicably linked to the proxy server for transcoding and decompressing the request, and transcoding and compressing the response including the requested message from the website. MDS gateway further processes a redirect response and request and fetches the requested message from another address. The proxy server sends a notification to the browser with respect to the redirect occurred in the MDS gateway and receives a request for requesting the requested message from the browser, and the proxy server sends the requested message to the browser. The redirect happens within the handheld device and does not happen wirelessly. The proxy caches images for browser to request to reduce the image transmission wirelessly.

Claims

1. A system for enhancing network-browsing speed on a handheld device, comprising:

a browser operating on the handheld device for generating request for requesting a message from a website;

a proxy server provided on the handheld device in communication with said browser;

a wireless network communicably linked to the proxy server; and

a Mobile Data Service (MDS) gateway communicably linked to the proxy server through the wireless network;

wherein said proxy server receives said request from sad browser, compresses said request and transmits the compressed request to said MDS gateway through the wireless network, wherein said MDS gateway decompresses the compressed request to obtain the request, provides said request to said website and receives a response to said request, wherein if said response references one or more images, said MDS gateway obtains said at least one or more images, compresses said response and said at least one image and transmits the compressed response and one or more images to said proxy server through the wireless network, wherein the proxy server decompresses the compressed response and one or more images to obtain the response and the one or more images, provides the response to the browser and stores the one or more images, and wherein, in response to a request for one or more of said one or more images received from said browser, said proxy server provides said one or more of said one or more images to said browser.

2. The system of claim 1, wherein if the response is a redirect response including an address of the requested message, the MDS gateway sends a redirect request for requesting the message to the address, the proxy server sends a notification to the browser indicating that a redirect occurred in the MDS gateway, the browser sends a request to the proxy server for requesting the requested message;

and the proxy server sends the requested message to the browser.

3. The system of claim 1, wherein the request includes multiple headers, and wherein the proxy server examines each header of the request individually, removes any header determined to be not acceptable by the MDS gateway, replaces each removed header with a new header acceptable by the MDS gateway, and tokenizes each non-removed header and new header, if any.

4. The system of claim 3, wherein the proxy server adds to the request a header identifying the handheld device'"'"'s screen dimension and a header requesting the MDS gateway to resize the one or more images for fitting the screen dimension.

5. The system of claim 4, wherein the MDS gateway de-tokenizes the headers of the request.

6. The system of claim 1, wherein the MDS gateway tokenizes one or more headers of the response.

7. The system of claim 6, wherein the response includes multiple headers, the proxy server examines each response header individually, de-tokenizes each response header, removes any response headers determined to be not acceptable by the browser, and replaces each removed response header with a new response header acceptable by browser.

8. The system of claim 1, wherein the proxy server further comprises a cache and wherein the one or more images received from the MDS gateway are stored in the cache.

12. The system of claim 1, wherein the requested message comprises a HTML page, said one or more images being embedded in the HTML page.

13. The system of claim 1, wherein the request is a protocol request using a TCP connection.

14. The system of claim 1, wherein the request is a protocol request using UDP.

9-11. -11. (canceled)

15. A method for enhancing network-browsing speed on a handheld device, comprising:

generating at a browser provided on said handheld device a request for requesting a message from a website;

providing the request to a proxy server;

compressing the request at the proxy server;

wirelessly sending the compressed request to a MDS gateway;

decompressing the compressed request at the MDS gateway to obtain the request and provide the request to the website;

receiving a response from the website by the MDS gateway in response to the request said response referencing one or more images;

obtaining the one or more images at the MDS gateway;

compressing the response and the one or more images at the MDS gateway;

wirelessly sending the compressed response and one or more images to the proxy server;

decompressing the compressed response and one or more images at the proxy server,

storing the one or more images in a cache associated with the proxy server;

providing the response to the browser;

receiving at the proxy server a request from the browser for one or more of said one or more images; and

obtaining the one or more of the one or more images from the cache and sending the one or more of the one or more images to the browser.

16. The method of claim 15, wherein if the response is

a redirect response including an address of the requested message, the method further comprises

sending a redirect request for requesting the requested message to the address from the MDS gateway;

and

receiving a response including the requested message at the MDS gateway.

17. The method of claim 16, further comprising:

sending a redirect response including the address from the proxy server to the browser;

receiving a request to request the requested message from the address from the browser, and

sending the requested message to the browser by the proxy server.

18. The method of claim 15, wherein the request includes one or more headers, and wherein before the step of compressing the request by the proxy server, the method further comprises:

examining the headers of the request;

removing a header determined to be not acceptable by the MDS gateway;

replacing each removed header with a new header acceptable by MDS gateway; and

tokenizing each non-removed the header and new header, if any.

19. The method of claim 18, further comprising adding to the request a header identifying the handheld device'"'"'s screen dimension and a header requesting the MDS gateway to resize the one or more images for fitting the screen dimension.

20. The method of claim 19, further comprising de-tokenizing the headers of the request at the MDS gateway.

21. The method of claim 15, wherein the response includes multiple headers, and wherein before the step of compressing the response by the MDS gateway, the method further comprises tokenizing the headers of the response.

22. The method of claim 21, wherein after the step of decompressing the response by the proxy server, the method further comprises:

examining the headers of the response;

de-tokenizing the headers of the response;

removing any response header not acceptable by the browser; and

replacing each removed response header with a response header acceptable by the browser.

23. The method of claim 15, wherein the request for requesting the message is a protocol request using a TCP connection.

24. The method of claim 15, wherein the request for requesting the message is a protocol request using UDP.
