Abstract

An information browser system and method enables sending of information requests to remote information sources and receiving of requested information from the remote sources on a wireless communication device. Information in any of a plurality of formats, including WML, HTML and WMLScript, is converted into a format in which the information can be displayed or otherwise further processed by the device. Information browsing functions may also be integrated with other communication functions on a mobile communication device.

Claims

1. A web browser comprising:

a page cache containing a plurality of pages in a plurality of formats; and

a converter and renderer operatively connected to the page cache for rendering the plurality of pages for display by the browser.

2. The browser of claim 1, further comprising a communication module configured to obtain pages and converters over a communications link.

3. The browser of claim 2, wherein the communications link comprises a wireless network.

4. The browser of claim 2, the browser having a plurality of communications interfaces configured for communications via a plurality of communication protocols, the communication protocols including Wireless Application Protocol (WAP) and Hypertext Transfer Protocol (HTTP).

5. The browser of claim 4, wherein pages obtained via HTTP are in a filtered format generated by a WML filter.

6. The browser of claim 4, wherein pages obtained via HTTP are in a filtered format generated by an HTML filter.

7. A wireless web browser, the browser comprising a radio configured for communications with both a Wireless Application Protocol (WAP) gateway and an Internet Protocol (IP) proxy server.

8. The browser of claim 7, the IP proxy server further comprising a Wireless Markup Language (WML) filter.

9. The browser of claim 7, the IP proxy server further comprising a Hypertext Markup Language (HTML) filter.

10. The browser of claim 7, the IP proxy server further comprising a Hypertext Transfer Protocol (HTTP) connector.

11. A web browser, the browser having a background processing object, the background processing object permitting the browser to access information after the browser has been closed.

12. The browser of claim 11, further comprising a message store, the message store containing processing results from the background processing object, the message store accessible to one or more applications to permit the displaying of the results to a user.

13. The browser of claim 12, wherein the message store comprises at least one browser folder.

14. The browser of claim 13, wherein the at least one browser folder comprises at least one page model.

15. The browser of claim 11, wherein:

the browser is implemented in a wireless communication device; and

the background processing object stores information requests from the browser and automatically sends stored requests over a wireless communication network when the device is within a coverage area of the network.

16. A web browser comprising a message store, the message store connected to at least one application selected from the set of:

email application, voicemail application and SMS application, and the message store containing objects retrieved by the browser and the least one application.

17. The browser of claim 16, wherein the message store comprises at least one folder.

18. The browser of claim 17, wherein the at least one folder includes at least one page model.

19. The browser of claim 16, wherein the message store also contains requests for information from the web browser.

20. The browser of claim 19, implemented in a wireless communication device.

21. The browser of claim 20, wherein the wireless communication device is selected from the group consisting of:

cellular telephones, personal digital assistants (PDAs), and two-way pagers.

22. The browser of claim 20, wherein the requests for information from the web browser are maintained in the message store until requested information is received in response thereto.

23. The browser of claim 22, wherein a stored request for information is replaced with the requested information in the message store.

24. The web browser of claim 16, wherein an object retrieved by the browser contained within the message store may be selected to initiate an instance of the browser.

25. A computer readable medium comprising instructions for implementing a page cache, a renderer controller operatively connected to the page cache and a serialization manager operatively connected to the renderer controller.

26. The medium of claim 25, wherein the serialization manager contains instructions for selecting one of a plurality of converters.

27. The medium of claim 26, wherein each of the plurality of converters contains instructions for creating a renderer.

28. The medium of claim 27, wherein a renderer contains instructions for creating a page stored in the page cache on a display.

29. A method for installing a converter on a wireless device, the method comprising the steps of:

determining if the converter is registered on the wireless device;

if the converter is registered, then requesting the converter via a wireless network; and

when the converter is received in response to the request, installing the converter on the wireless device.

30. The method of claim 29, further comprising the steps of:

sending a request for information via the wireless network;

receiving requested information in response to the request;

selecting a converter for the requested information;

if the selected converter is installed on the device, executing the converter; and

if the selected converter is not installed on the device, continuing at the step of determining to install the converter on the device.

31. A method for rendering a page on a wireless communication device comprising the steps of:

receiving the page over a wireless network;

selecting a converter for the page;

rendering the page to created a rendered page for display by a browser; and

storing the rendered page in a page cache.

32. A browser for a wireless device, the browser comprising:

a browser object operatively connected to a browser daemon;

a stack manager operatively connected to the browser object and the browser daemon;

the stack manager further connected to a wireless radio via a plurality of interface adapters; and

the radio connected to a plurality of communication links, the communication links providing information to and sending information from the browser object and the browser daemon.

33. The browser of claim 32, wherein the communication links comprise links to a WAP gateway and an IP proxy server.

34. The browser of claim 32, wherein the IP proxy server comprises a WML filter.

35. The browser of claim 32, wherein the IP proxy server comprises an HTML filter.

36. The browser of claim 32, wherein the IP proxy server comprises an HTTP connector.

37. A computer readable medium comprising instructions for implementing a browser for a wireless device said medium comprising:

instructions for implementing a browser object and a browser daemon, the browser object and the browser daemon communicating with each other;

instructions for implementing a stack manager, the stack manager in communication with the browser object and the browser daemon;

instructions for implementing a plurality of interface adapters, the interface adapters in communication with the stack manager and a wireless radio; and

instructions for connecting the radio to a plurality of communication links, the communication links providing information to and sending information from the browser object and the browser daemon.

38. The medium of claim 37, wherein the communication links comprise links to a WAP gateway and an IP proxy server.

39. The medium of claim 37, wherein the IP proxy server comprises instructions for implementing a WML filter.

40. The medium of claim 37, wherein the IP proxy server comprises instructions for implementing an HTML filter.

41. The medium of claim 37, wherein the IP proxy server comprises instructions for implementing an HTTP connector.
