Abstract

A system for enhancing network-browsing speed by setting a proxy server on a handheld device is disclosed. The system comprises a browser for sending a request for requesting a message from a website and receiving a response in response to the request, a proxy server for transcoding and compressing the request, and transcoding and decompressing the response including the requested message, a wireless network communicably linked to the proxy server, and Mobile Data Service (MDS) gateway communicably linked to the wireless network for transcoding and decompressing the request, and transcoding and compressing the response including the requested message from the website. MDS gateway further receives a redirect response including an address of the requested message and sends a redirect request for requesting the message from the address if there is no requested message at the website, the proxy server sends a notification to the browser with respect to the 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. The redirect occurs between the proxy server and the browser within the handheld device, and does not happen wirelessly to enhance the network browsing speed.

Claims

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

a browser operating on the handheld device for sending a request for requesting a message from a website and receiving a response in response to the request;

a proxy server setting on the handheld device for transcoding and compressing the request, and transcoding and decompressing the response including the requested message in response to the request;

a wireless network communicably linked to the proxy server; and

a Mobile Data Service (MDS) gateway communicably linked to the wireless network for transcoding and decompressing the request, and transcoding and compressing the response including the requested message from the website.

2. The system of claim 1, wherein

the MDS gateway further receives a redirect response including an address of the requested message, sends a redirect request for requesting the message from the address and receives the requested message if there is no requested message at the website;

the proxy server sends a notification to the browser with respect to the 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, the proxy server examines headers of the request individually, removes the header not acceptable by the MDS gateway, adds the header acceptable by the MDS gateway, and tokenizes the header.

4. The system of claim 3, wherein the MDS gateway de-tokenizes the headers of the request.

5. The system of claim 1, wherein the MDS gateway tokenizes the header of the response.

6. The system of claim 1, wherein the response includes multiple headers, the proxy server examines each header individually, de-tokenizes each header, removes the header not acceptable by the browser, and adds the header acceptable by browser.

7. The system of claim 1, wherein the request for requesting the message is a protocol request using TCP connection.

8. The system of claim 1, wherein the request for requesting the message is a protocol request using UDP.

9. A method for enhancing network-browsing speed by setting a proxy server on a handheld device, comprising:

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

transcoding and compressing the request by the proxy server;

sending the request to a MDS gateway via a wireless network;

transcoding and decompressing the request by the MDS gateway;

receiving a response from the website by the MDS gateway;

transcoding and compressing the response by the MDS gateway;

sending the response to the proxy server via the wireless network;

transcoding and decompressing the response by the proxy server; and

receiving the response by the browser.

10. The method of claim 9, further comprising:

receiving a redirect response including an address of the requested message by the MDS gateway if the requested message is not at the website;

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

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

11. The method of claim 10, further comprising:

sending a notification including an address of the requested message to the browser and regarding no the requested message at the website by the proxy server;

receiving a request for requesting the requested message from the browser; and

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

12. The method of claim 9, before the step of transcoding and compressing the request by the proxy server, further comprising:

examining the headers of the request;

removing the header not acceptable by the MDS gateway;

adding the header acceptable by MDS gateway; and

tokenizing the header.

13. The method of claim 12, before the step of transcoding and decompressing the request by the MDS gateway, further comprising de-tokenizing the headers of the request.

14. The method of claim 9, before the step of transcoding and compressing the response by the MDS gateway, further comprising tokenizing the headers of the response.

15. The method of claim 14, after the step of transcoding and decompressing the response by the proxy server, further comprising:

examining the headers of the response;

de-tokenizing the headers;

removing the header not acceptable by the browser; and

adding the header acceptable by browser.

16. The method of claim 9, wherein the request is a protocol request using a TCP connection.

17. The method of claim 9, wherein the request is a protocol request using UDP.
