Abstract

A wireless communication system allows mobile users to access a resource from a content server. The wireless communication system includes a browser that allows mobile users to access resources through a wireless application protocol (WAP) compliant server. The (WAP) compliant server connects the browser to a content server. This connection allows resources to be passed between the browser and the (WAP) compliant server. The browser is further configured to transmit a request that includes an address for a resource, a protocol to be used, and one or more textual parameters encoded into a binary data packet. The wireless communication method includes generating a request for a resource; translating a textual portion of that request into binary data at the browser; transmitting the request to a wireless gateway; and converting the request into a format that is compatible with a protocol used by a receiving network.

Claims

1. A wireless communication system that allows mobile users to access a resource from a content server through a network comprising:

a browser that allows mobile users to access resources; and

a wireless application protocol compliant server programmed to couple the browser to a content provider server so that a resource may be passed between the browser and the wireless application protocol compliant server;

where the browser is configured to transmit a request that comprises an address for the resource, a protocol to be used, and one or more textual parameters encoded into a single binary data packet.

2. A communication system having a browser capability, comprising:

a wireless application protocol compliant server; and

a client coupled the server and adapted to transmit a request for a resource;

where the request comprises a single encoded parameter that includes an identification code that comprises a binary data packet.

3. The communication system according to claim 2, where the client comprises a wireless application protocol compliant client.

4. The communication system according to claim 2, where the request comprises a protocol to be used to access the resource and the name of a second server on which the resource resides.

5. The communication system according to the claim 2, where the request, is not more than 256 characters long.

6. The communication system according to claim 4, where request, is transmitted to the server after a handshake process.

7. The communication system according to claim 2, wherein the server is adapted to transmits data packets comprising an error checking code—

and binary data.

8. The communication system according to claim 6, where the data comprise a binary translation of textual data.

9. The communication system according to claim 4, where the length the request may vary with the resource requested.

10. The communication system according to claim 8, where the data packets sent from the server to the client have successive bits arranged as follows:

Identification code of the service (Service ID);

Length of the serial number;

Serial number, further reserved area for future applications;

Number of packets (last-section-number); and

Number of the package just sent (section number); and

Section number.

11. The communication system according to claim 7 where the identification code has a specified bit width that, makes it possible to decode the contained in the data packet.

12. The communication system according to claim 7 where the identification code is variable in length, and generated by the server.

13. The communication system according to claim 7 where the communication system comprises a navigation system.

14. The communication system according to claim 13 where the requested service comprises a query of the client'"'"'s current location.

15. The communication system according to claim 7 where the server is adapted to send data in a MIME format.

16. The communication system according to claim 7, where the client comprises a wireless Internet complaint browser.

17. The communication system according to claim 7, where the client comprises a navigation system resident to a radio.

18. The communication system according to claim 7 where the client comprises an Internet compliant hand-held wireless device.

19. The communication system according to claim 7 where the client comprises a Internet compliant device resident to a vehicle.

20. A wireless communication protocol method comprising:

generating a request for an publicly accessible resource;

translating a textual portion of the request into a binary data through a wireless browser;

transmitting the request to a wireless gateway; and

converting, the request at the gateway into a format that is compatible with a protocol used by a receiving network.
