Abstract

A browser device and method for interfacing screen-display telephone terminals with the Internet. The browser device located on an ADSI capable telephone platform server, retrieves requested data files from an Internet site and formats the retrieved data file specifically for display on the screen-display telephone terminal.

Claims

1. A method for retrieving Internet data files for display on an ADSI screen-display telephone terminal, the method comprising the steps of:

receiving, at a telephony platform server, a data file request corresponding to an Internet site location selected from the ADSI screen-display telephone terminal;

interpreting the received data file request to generate an Internet protocol message;

transmitting the Internet protocol message to an Internet site location, wherein the Internet protocol message corresponds to the data file request received and the Internet site location corresponds to the data file requested;

retrieving an Internet data file from the Internet site location;

formatting the Internet data file received in response to the Internet protocol message for display on the ADSI screen-display telephone terminal; and

transmitting the retrieved data file to the ADSI screen-display telephone terminal.

2. The method of claim 1, wherein the Internet protocol is a Hypertext Transfer Protocol (HTTP), and wherein the step of interpreting the received data file request includes the substep of

generating an HTTP formatted request message.

3. The method of claim 1, wherein the Internet data file received is formatted in a markup language, and wherein the step of retrieving the Internet data file includes the substep of

receiving the retrieved Internet data file at the telephony platform server.

4. The method of claim 1, wherein the Internet data file received is formatted in a markup language, and wherein the step of formatting the Internet data file includes

converting the retrieved Internet data file formatted in the markup language to an ADSI data display block.

5. The method of claim 4, wherein the markup language is a Hypertext Markup Language (HTML), and wherein the step of converting the markup language formatted data file includes the substep of converting the HTML data file to an ADSI protocol data display block.

6. The method of claim 4, wherein the markup language is a Handheld Device Markup Language (HDML), and wherein the step of converting the markup language formatted data file includes the substep of

converting the HDML data file to an ADSI protocol data display block.

7. A web browser device in an ADSI telephone system, wherein the system includes at least one ADSI screen-display telephone terminal and a telephone platform server connected to a plurality of Internet servers, the web browser device residing on the telephony platform server and comprising:

means for receiving an ADSI protocol data file request corresponding to an Internet site location from the at least one ADSI screen-display telephone terminal;

means, connected to the means for receiving, for interpreting the received data file request to generate an Internet protocol message;

means, connected to the means for interpreting, for transmitting the Internet protocol message to the Internet site location, wherein the Internet site location corresponds to the data file received from the at least one ADSI screen-display telephone terminal;

means for retrieving an Internet data file from the Internet site location;

means, connected to the means for retrieving, for formatting the Internet data file, received in response to the Internet protocol message, to an ADSI data display block; and

means for transmitting the ADSI data display block to the at least one ADSI screen-display telephone terminal.

8. The browser device of claim 7, wherein the data file retrieved from the Internet is formatted in a markup language, and wherein means for formatting further includes

means for converting the retrieved data file formatted in the markup language to the ADSI data display block.

9. The browser device of claim 8, wherein the markup language is a Hypertext Markup Language (HTML).

10. The browser device of claim 8, wherein the markup language is a Handheld Device Markup Language (HDML).
