Abstract

A system and method of browsing documents is provided that does not require a traditional document browsing application at a client device. In order to achieve browsing without a browsing application, the client device first transmits an information request to a host system. The host system retrieves the requested information from one or more information sources that store the information. A translation component receives the information from the host system and translates the information from a plurality of content types into a virtual machine language program. The virtual machine language program is then transmitted to the client device, which executed the virtual machine language program in order to display and interact with the information.

Claims

1. A system for browsing web pages maintained in a page-rendering language at a plurality of Internet web-servers, the page-rendered web-pages being formatted using one of a plurality of content types, comprising:

a wireless gateway system coupling a wireless data network to the Internet, the wireless gateway system including;

an information interface configured to send a web page request to an Internet web-server and to received a page-rendered web-page from the Internet web-server;

a plurality of content translators, each of the plurality of content translators being configured to translate page-rendered content of a particular content type into a run-time program;

the information interface being further configured to determine the content type of the received page-rendered web page and to route the received page-rendered web page to one of the plurality of content translators that is configured to translate the content type of the received page-rendered web page into the run-time program; and

a network interface configured to receive the web page request and to transmit the run-time program over the wireless data network; and

a wireless mobile communication device configured to transmit the web page request over the wireless data network to the wireless gateway and to receive the run-time program from the wireless gateway;

the wireless mobile communication device including a virtual machine that is configured to directly execute the run-time program to display a representation of the page-rendered web page.

2. The system of claim 1, wherein the wireless gateway system further comprises a data compressor for compressing the run-time program prior to transmission to the wireless mobile communication device.

3. The system of claim 2, wherein the data compressor includes a byte code generator for converting the run-time program into a compressed byte code format.

4. The system of claim 1, wherein the page-rendered language is HTML, HDML, XML or WML.

5. The system of claim 1, wherein the wireless mobile communication device further comprises a file explorer component for generating the web page request and for storing the run-time program received from the wireless gateway system.

6. The system of claim 5, wherein the file explorer component generates a second web page request and determines if a stored run-time program corresponding to the second web page request is already stored at the wireless mobile communication device, and if so, then the virtual machine executes the stored run-time program.

7. A wireless gateway system for coupling a wireless data network to the Internet so that a wireless mobile communication device may browse web pages maintained in a page-rendering language at a plurality of Internet web-servers, the page-rendered web-pages being formatted using one of a plurality of content types, comprising:

an information interface configured to send a web page request to an Internet web-server and to received a page-rendered web-page from the Internet web-server;

a plurality of content translators, each of the plurality of content translators being configured to translate page-rendered content of a particular content type into a run-time program;

the information interface being further configured to determine the content type of the received page-rendered web page and to route the received page-rendered web page to one of the plurality of content translators that is configured to translate the content type of the received page-rendered web page into the run-time program; and

a network interface configured to receive the web page request and to transmit the run-time program over the wireless data network to the wireless mobile communication device, wherein the wireless mobile communication device includes a virtual machine for directly executing the run-time program to display a representation of the page-rendered web page.

8. The wireless gateway system of claim 7, further comprising:

a data compressor for compressing the run-time program prior to transmission to the wireless mobile communication device.

9. The wireless gateway system of claim 8, wherein the data compressor includes a byte code generator for converting the run-time program into a compressed byte code format.

10. The wireless gateway system of claim 7, wherein the page-rendered language is HTML, HDML, XML or WML.

11. A method for browsing web pages maintained in a page-rendering language at a plurality of Internet web-servers, the page-rendered web-pages being formatted using one of a plurality of content types, comprising:

receiving a web page request from a wireless mobile communication device over a wireless data network;

sending the web page request over the Internet to an Internet web-server;

receiving, in response to the web page request, a page-rendered web page from the Internet web-server;

determining a content type of the page-rendered web page;

routing the page-rendered web page to one of a plurality of content translators based on the content type, wherein each of the plurality of content translators is configured to translate page-rendered content of a different content;

translating the page-rendered web page into a run-time program; and

transmitting the run-time program over the wireless data network to the wireless mobile communicate device, wherein the wireless mobile communication device includes a virtual machine for directly executing the run-time program to display a representation of the page-rendered web page.

12. The method of claim 11, further comprising:

compressing the run-time program prior to transmitting it to the wireless mobile communication device.

13. The method of claim 11, wherein the web page request is a Uniform Resource Locator request which is transmitted using the Hypertext Transfer Protocol.

14. The method of claim 11, wherein the page-rendered language is HTML, HDML, XML or WML.
