Abstract

A device for providing wireless Internet access has been described. The device includes an antenna. The antenna is for receiving wireless queries and transmitting wireless responses. The device includes a program. The program is for converting the wireless queries into Internet compatible protocols. The program is for receiving the Internet protocol formatted responses. These responses are then converted in to the wireless responses.

Claims

1. A computer-readable medium, the computer-readable medium carrying instructions which, when executed by one or more processors of a handheld computer, cause the one or more processors to perform the steps of:

storing in a memory a set of data configured for a selected network site;

accessing the set of data from the memory to render a form for the selected network site, the form including one or more fields;

associating user-input to the one or more fields provided by the form;

signaling a wireless communication over an antenna for the selected network site, the wireless communication comprising the form with the user-input being associated with the one or more fields;

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

providing a content comprising one or more selectable pages appearing on a display, a first portion of the content being derived from the set of data for the selected network, a second portion of the content being derived from the response received over the antenna from the selected network site.

2. A computer-readable medium for transmitting a message from a wireless client, the computer-readable medium carrying instructions which, when executed by one or more processors, cause the one or more processors to perform:

transmitting a single message from the wireless client to a proxy server, the single message comprising a single packet of data, the single packet of data having a base document uniform resource locator followed by compressed data, the compressed data comprising references to fields in a hyperlink document disposed in the base document, and an indication of use of the hyperlink document.

3. A computer-readable medium for securely transmitting a message from a wireless client, the computer-readable medium carrying instructions which, when executed by one or more processors, cause the one or more processors to perform steps of:

encrypting a local key using a public key on a proxy server to form an encrypted local key, the local key corresponding to a specific transaction between the wireless client and the proxy server;

encrypting the message using the local key to form an encrypted message; and

transmitting the encrypted message to the proxy server, the encrypted message comprising at least one packet of data, and an encrypted request message corresponding to a hypertext document, the encrypted request message further comprising encrypted request parameters, an encrypted bit, an encryption scheme identifier, a proxy server public key identifier, a proxy server identifier, a wireless client generated indication of current date and time, an encrypted request message integrity check, and the encrypted local key, the encrypted request parameters created from request parameters using the local key, the request parameters including compressed representations of data corresponding to fields in the hypertext document, the compressed representations formatted according to a compact transfer protocol, the encrypted request message integrity check encrypted using the local key.

4. A computer-readable medium for wireless communications, the computer-readable medium carrying instructions which, when executed by one or more processors, cause the one or more processors to perform steps of:

receiving a user-input entered through a wireless application executing on a wireless device;

in response to the user-input, using the wireless application to generate a compressed query from the wireless application;

sending the compressed query to a proxy server external to the wireless device to cause the proxy server to request data from an Internet site;

receiving a compressed response from the proxy server, the compressed response including data from the Internet site;

executing the wireless application to process the compressed response in order to cause the data from the Internet site to be rendered on the wireless device from the compressed response; and

wherein executing the wireless application to generate a compressed query includes generating the query in compressed markup language (CML).
