Abstract

A system having a distributed web site is described. The web site is distributed between a client, a server and a web server. The client stores a set of predefined applications that correspond to a part of the web site. The applications are formatted according to a first markup language. From the set of predefined applications, the client can generate queries. The server receives the queries and generates new, related queries. The new queries correspond to a second query protocol. The second query protocol is used by the web server. The web server generates responses to the new queries and sends these responses to the server. The responses are formatted according to a second markup language. These responses correspond to the second portion of the web site. The server then converts the responses into new responses that the client can use.

Claims

1. A handheld computer comprising:

a display;

an antenna;

a local memory configured to store sets of predefined data comprising executable wireless applications, each wireless application representing a static portion of a different website; and

a processor configured to;

present on said display service icons corresponding to said wireless applications;

in response to user activation of a displayed icon, execute the corresponding wireless application stored in local memory;

render a query form stored in local memory for the selected website associated with that wireless application;

generate a query based on user-input to the query form;

send a wireless communication over the antenna for the selected website, the wireless communication comprising the query with the user-input;

receive a response over the antenna, the response representing dynamic data originating from the selected website; and

present one or more pages on the display comprising static data derived from the set of predefined data for the selected website and dynamic data derived from the response received over the antenna from the selected website.

2. The handheld computer of claim 1, wherein the wireless communication is signaled from the antenna in a compressed markup language.

3. The handheld computer of claim 2, wherein the compressed markup language corresponds to Compact Markup Language (CML).

4. The handheld computer of claim 1, wherein the one or more pages are linked to one another, and wherein at least some of the data for linking the one or more pages to one another is stored with the set of predefined data configured for the selected network site.

5. The handheld computer of claim 1, wherein the response originating from the website is received from the website in a compressed markup language.

6. The handheld computer of claim 1, wherein the processor is further configured to execute an application associated with the selected website, the application accessing the set of predefined data to generate the form for the selected website.

7. The handheld computer of claim 6, wherein the application associates a plurality of network pages configured for the selected website.

8. The handheld computer of claim 1, further comprising a serial port to exchange communications with another computer, and wherein the set of predefined data for the selected website is signaled from another computer over the serial port.

9. A method comprising:

storing sets of predefined data comprising executable wireless applications, each wireless application representing a static portion of a different website, in a memory of a handheld computer;

presenting on a display of the handheld computer service icons corresponding to said wireless applications;

in response to user activation of a displayed icon, executing the corresponding wireless application stored in local memory;

rendering a query form stored in local memory for the selected website associated with that wireless application;

generating a query based on the user-input to the query form;

sending a wireless communication over an antenna of the handheld computer for the selected website, the wireless communication comprising the query;

receiving a response over the antenna, the response originating from the selected website; and

presenting one or more pages on the display of the handheld computer comprising static data derived from the set of predefined data for the selected website and dynamic data derived from the response received over the antenna from the selected website.

10. The method of claim 9, wherein the wireless communication is signaled from the antenna in a compressed markup language.

11. The method of claim 10, wherein the compressed markup language corresponds to Compact Markup Language (CML).

12. The method of claim 11, wherein the one or more pages are linked to one another, and wherein at least some of the data for linking the one or more pages to one another is stored with the set of predefined data configured for the selected website.

13. The method of claim 9, wherein the response originating from the website is received from the network site in a compressed markup language.

14. The method of claim 9, further comprising:

executing an application associated with the selected website, the application accessing the set of predefined data to generate the query form for the selected website.

15. The method of claim 14, wherein the application associates a plurality of network pages configured for the selected website.

16. The method of claim 9, wherein the set of predefined data for the selected website is signaled from another computer over a serial port of the handheld computer.
