`SYSTEM AND METHOD FOR RETRIEVING
`INTERNET DATA FILES USING A SCREEN
`DISPLAY TELEPHONE TERMINAL
`
`BACKGROUND OF THE INVENTION
`
`A. Field of the Invention
`This invention generally relates to the ?eld of Analog
`Display Services Interface (ADSI) and in particular to a
`system and method for interfacing a screen-display tele
`phone device With the World Wide Web or Internet.
`B. Description of the Prior Art
`
`1. ADSI Display Devices
`ADSI is a telecommunications protocol standard devel
`oped by Bellcore and published in Bell Communications
`Research report “Generic Requirements for an SPCS to
`Customer Premises Equipment Data Interface for Analog
`Display Services,” Technical Reference TR-NWT-001273,
`Dec. 1992 (incorporated herein by reference). ADSI enables
`alternate voice and data capability over the existing analog
`telephone netWork. This capability permits ADSI devices to
`communicate With users through a familiar voice response
`audio interface, Where the user listens to voice recordings
`and makes menu selections using the telephone keypad, and
`With visual menus and information on a screen display,
`Where service selections can be made using softkeys.
`Currently, ADSI devices are often implemented as screen
`display telephone terminals, but there can also be television
`set-top boxes alloWing users to make calls using the
`television, personal digital assistants (PDAs), pagers, and
`personal computers that are ADSI capable.
`In addition to real-time interactive applications, ADSI
`also enables program transfer using a capability knoWn as
`Feature DoWnload. These programs, or service scripts, can
`be developed by a server and run on a local terminal. In
`many cases, these scripts are created by an authoring tool
`and stored in an external database for access by the tele
`phony platform serving the user. Therefore, When neW
`features are requested by the user, or are neWly added by the
`server, the scripts are transferred by the telephony platform
`to the ADSI terminal Where they are stored in memory and
`executed by the terminal until overWritten. These scripts
`de?ne not only call ?oW, but also de?ne the softkeys and
`displays presented to the user during a call.
`One example of applied ADSI technology is Northern
`Telecom’s Advanced Call Management Service (ACMS). In
`ACMS, customer selected features are stored in an external
`database. When a customer calls in for activation of services,
`a database lookup is performed so that the appropriate
`information for that customer can be doWnloaded to the
`telephone. The application runs on a NetWork Applications
`Vehicle (NAV), Which is typically a UNIX-based telephony
`platform, and Which reads an object ?le to get information
`concerning the call ?oW. The NAV presents the call ?oW,
`including ADSI commands, to the end user and as a result
`a neW application is presented to the terminal.
`In addition, any server may create Custom Local Area
`Signaling Services (CLASS)SM or Custom Calling Features
`(CCF) and doWnload these advanced feature doWnload
`scripts that are speci?cally tailored to the user’s service
`subscription. As a result, a user can activate services such as
`three-Way calling, call Waiting, and call forWarding through
`context sensitive screen prompts and softkeys. These
`advanced call management telephony script applications
`have been a primary area of development for ADSI display
`terminals.

`An example of advanced ADSI script transfer is disclosed
`in US. Pat. No. 5,541,986, to Hou. Speci?cally, Hou dis
`closes a method and system for automatically consolidating
`service scripts for doWnloading to ADSI-compatible screen
`display telephones. The method and system comprises
`specifying a general template for a set of service features,
`specifying line speci?c attributes for a feature, and then
`combining the tWo into a service module. A customer’s
`service is composed of multiple service modules Which,
`When selected, Would be consolidated by a netWork server
`computer into a single service script. Hou also discloses
`compiling the consolidated service script for doWnloading
`and transmission to a local processor in the compatible
`screen-display telephone.
`
`2. The Internet
`
`The Internet, or “net,” fueled by the popularity of the
`World Wide Web (W or Web), has exhibited signi?cant
`groWth over the past feW years. At present, to access the
`information available on the Web, users typically use stan
`dard computer equipment, such as a home personal com
`puter With a display and modem, and an Internet connection.
`There have been efforts to expand the number of users and
`the ease With Which they access the net. For example, several
`companies have developed television set-top boxes that
`permit users to broWse or “surf” the Internet from their
`television sets. In addition, telephone companies have joined
`With softWare developers to alloW mobile communication
`devices such as cellular telephones, pagers, and PDAs to
`access some features of the Internet.
`At present, several types of Internet connections are
`available. For example, to use an Internet connection from
`Internet Service Providers (ISPs), the user dials into a
`computer at the ISP’s facility using a modem and standard
`telephone line. The ISP’s computer in turn provides the user
`With access to the Internet. Through this Internet connection,
`the user can access information on the Web using a computer
`program called a “Web broWser,” such as for example the
`Netscape NavigatorTM from Netscape Communications Cor
`poration. The Web broWser is a softWare program that alloWs
`a user to vieW the data received from an Internet site
`location. To accomplish this, the user gives the Web broWser
`a Uniform Resource Locator (URL) for an object on the
`Internet, for example, a data ?le containing information of
`interest. The document is referred to as a “Web page,” and
`the information contained in the Web page is called content.
`Web pages often refer to other Web pages using “hypertext
`link” or “hyperlinks” that include Words or phrases repre
`senting the other pages in a form that gives the broWser the
`URL for the corresponding Web page When a user selects a
`hyperlink.
`Hyperlinks are made possible by building Web pages
`using a Hypertext Markup Language (HTML), an evolving
`language Which is used to construct documents in a uniform,
`standardiZed format so they may be accessed by Web
`broWsers and displayed for the user. HTML is an ASCII
`text-based language Which de?nes page formats used to
`display the HTML elements. To ensure accessibility, all
`HTML documents have a “point-of-contact” name, or
`ANCHOR, identi?ed in the document as part of the
`ANCHOR element. This name is hyperlink-enabled by
`surrounding the name With the <A >element. This feature
`permits a user to link With another URL When the ANCHOR
`element is selected.
`Once the user selects a site to visit, the URL identi?es a
`speci?c host computer on the Internet, called a “Web
`
`Apple, Exhibit 1046, Page 10
`
`

`

`5,937,041
`
`3
`Server,” and, more particularly, the location of a Web page
`located on the Web Server. The Web broWser retrieves the
`Web page and displays it for the user.
`Hypertext Transfer Protocol (HTTP) is the most Widely
`used format to access and link users With various other Web
`pages or sites referenced by the original Web page. HTTP
`requires a program running on the host computer that
`understands and responds to this protocol. The ?le retrieved
`might be, for example, an HTML ?le, a graphic ?le, a sound
`?le, an animation sequence ?le, a ?le to be executed by the
`Web server (e.g., CGI programs), or a Word processing ?le.
`Ultimately, Whether the ?le can be retrieved or handled
`depends on the features and capabilities of the broWser.
`When a broWser requests a speci?c URL, it sends the request
`to the sponsoring Web server. The Web server receives the
`request and attempts to ful?ll the request.
`There are several Ways that user requests can be ful?lled.
`For example, Web servers translate a request such as “http://
`WWW.recipes.com/recipes/soup.htm” into a search for a
`physical ?le on that server. It Would start from the base
`directory for that domain and then apply the path that Was
`requested. In this example, the Web server Would look for a
`directory called “recipes” and then look for a ?le called
`“soup.htm” Within that directory. If the ?le Was found it
`Would be passed back, Without modi?cation, to the request
`ing broWser. In this Way, the URL can be thought of as a
`speci?c ?le sitting on a server, or host computer.
`Common GateWay Interface (CGI) Was created as one
`Way for Web servers to achieve a dynamic element by
`calling to programs that reside on the server. This dynamic
`element alloWs the Web server to immediately respond to the
`request Without doing additional processing. The server
`receives a request from the broWser, and it uses the dynamic
`element, or hypertext link, to connect With a neW process.
`The server then passes CGI based tagged data that Will be
`used by the program to create, for example, the HTML ?le.
`The CGI program executes the associated display format
`subroutine, or script ?le, and accesses other data sources to
`generate the content and then returns the HTML back to the
`HTTP server. Once the transfer is completed, the CGI
`process terminates and the server transfers the HTML back
`to the requesting broWser.
`An alternative to using separate CGI scripts to de?ne
`content is a template-based HTML that actually embeds a
`request for the dynamic data Within the HTML ?le itself
`When a speci?c page is requested, a pre-processor scans the
`?le for proprietary tags that are then translated into ?nal
`HTML based on the request. The ?nal HTML is then passed
`back to the server and on to the broWser for the user to vieW
`on their computer terminal. While the examples given have
`been explained in the context of HTML, both CGIs and
`templates may be created With any Standard Generalized
`Markup Language (SGML) based markup language, such as
`Handheld Device Markup language (HDML). HDMI, is a
`markup language designed and developed by AT&T and
`UnWired Planet, Inc. to alloW handheld devices some access
`to the resources of the Internet. The speci?cs of the language
`are disclosed in “HDML Language Reference, Version 1.0,”
`UnWired Planet, Inc., Jul. 1996, and herein incorporated by
`reference.
`While computer terminals and other devices that are
`con?gured to receive HTTP signals and HTML ?les may
`utiliZe the above methods to access and vieW the Internet
`data, the speci?c display standards for ADSI devices, as Well
`as the display capabilities for ADSI and other screen-display
`telephones, alloW only a limited vieW of HTTP transferred
`
`15
`

`

`

`

`HTML ?les. In addition, ADSI display characteristics do not
`permit a user to take advantage of the hypertext features
`imbedded in most HTML data ?les.
`While the capability of ADSI devices have been explored
`to provide users With more advanced consumer-based tele
`phone services, ADSI devices have not previously been
`integrated successfully and effectively With the vast
`resources of the Internet. In addition to permitting ADSI
`devices to retrieve data ?les from the Internet, the proposed
`ADSI Internet interface Would also provide users With the
`ability to “jump” betWeen ADSI applications by giving
`applications an imbedded link to other ADSI applications.
`This bene?t Would be similar to the bene?ts of hyperlinks
`used in HTML and has not been effectively implemented for
`ADSI application. Therefore, a need exists for a system and
`method that Would alloW ADSI devices to access and
`retrieve data from the Internet as Well as link ADSI appli
`cations.

`preferred embodiments of the invention, examples of Which
`are illustrated in the accompanying draWings. Wherever
`possible, the same reference numbers Will be used through
`out the draWings to refer to the same or like parts.
`A. The System
`FIGS. 1 and 2 are block diagrams shoWing an ADSI-based
`Internet access system 100 consistent With the present
`invention. FIG. 1 shoWs the overall make-up of the system
`100, While FIG. 2 shoWs a more detailed layout of the
`system 100. A telephone terminal, such as an ADSI screen
`display telephone terminal 110 or other suitable Customer
`Premise Equipment (CPE), having an integrated screen
`display 111, is connected to public sWitched telephone
`netWork (PSTN) 120 that routes calls and data transfers from
`terminal 110 to the NetWork Application Vehicle (NAV) 130
`via standard telephone interface lines 112 and 122. NAV 130
`is a telephony platform server for controlling call and data
`How betWeen the terminal 110 and the Web 140. As further
`described beloW, NAV 130 includes ADSI Internet BroWser
`(AIB) 180, an ADSI protocol speci?c Web broWser that can
`retrieve data ?les from the Internet and format the data ?le
`to an ADSI protocol formatted data display block for display
`on screen-display 111. NAV 130 also contains a memory
`device 132 for receiving and storing Internet protocol
`messages, and a memory device 134 for storing data ?les
`and messages transmitted from the Internet.

`The Web 140, as Well as the term Internet, are generic
`terms for a multiple of Well knoWn protocols and standards
`used over a standard datalink such as connections 145 and
`146. Host Server 155 is a remote computer system acces
`sible over the Internet or other communication medium
`along line 145. Host computer Server 155 contains Web
`Server 150, Which is a server application program for
`accessing Web pages from various Internet sites and retriev
`ing data ?les from, for example, URLs 160—162, through the
`Internet using existing Web architecture. Preferably, Web
`Server 150 presents the accessed Web pages to the requestor,
`in this case AIB 180, in HTML format. Web Server 150 also
`permits a service provider to insert ANCHOR “tags” on
`speci?c Web pages that Would point AIB 180 to speci?cally
`designed ADSI Telephone Hypertext Markup Language
`(ATML) ?les or also HDML formatted data ?les. Moreover,
`Web Server 150 receives Internet requests from AIB 180
`through the Web 140 to locate and access a number of URLs,
`such as for example URLs 160—162. URLs 160—162 could
`be Web site locations such as a Yahoo Home Page, a Nortel
`Home Page, or a Lycos Homepage, and additional URLs
`could include a Hello World Homepage, or a time/
`temperature site.
`Terminal 110 may be any ADSI compatible device, or
`other screen-display telephone terminal, capable of receiv
`ing and storing upgrade command ?les, service scripts, and
`transmitted data from NAV 130 through PSTN 120. One
`example is Nortel’s PoWer Touch 350, Which includes an 8
`x20 character LCD screen-display 111, a series of program
`mable softkeys 113 for a user’s selection of a particular data
`?le or other displayed functions, a standard telephone
`speaker 114, handset 115, and a standard 12 character
`telephone key pad 116.
`Terminal 110 communicates With NAV 130 by standard
`transmission of ADSI protocol transmission signals along
`line 112, PSTN 120, and line 122. The ADSI protocol
`transmission signals may include, but are not limited to,
`Dual Tone Multi Frequency (DTMF) signals. For a more
`detailed description of ADSI communication signal
`requirements, refer to Bell Communications Research report
`“Generic Requirements for an SPCS to Customer Premises
`Equipment Data Interface for Analog Display Services,”
`Technical Reference TR-NWT-001273, Dec. 1992
`(incorporated herein by reference).
`NAV 130 may be any telephony platform capable of
`retrieving, storing, and transmitting both data and command
`?les. In the present embodiment, and by Way of example
`only, NAV 130 can be a UNIX-based ADSI capable platform
`implemented through Well-knoWn hardWare, but With spe
`ci?c softWare functions described herein for the present
`invention. NAV 130 includes a UNIX-based processor, and
`a number of internal memory locations including, a ?rst
`memory 132 for receiving and storing data ?les and mes
`sages transmitted from terminal 110, and a second memory
`134 for receiving data ?les from the Internet. NAV 130 also
`includes AIB 180 Which is connected to memory devices
`132 and 134 via data bus 133. In addition, as further
`described beloW, NAV 130 controls the call How and data
`transfers betWeen the Host Server apparatus 155 and termi
`nal 110. NAV 130 also alloWs a service provider to create
`and store ADSI data ?les Written in a markup language
`speci?cally formatted for screen-display telephone termi
`nals. This language could comprise a standard text-based
`markup language similar to HTML, or could include a
`modi?ed version of HDML, or a speci?cally designed
`ATML, and serve as a substitute for conventional ADSI
`scripting language.

`FIG. 3 shows a functional block diagram of the AIB 180
`in greater detail. The speci?c functions of the sections are
`described in greater detail below in conjunction With FIGS.
`4—8. AIB 180 contains a request message receiving and
`formatting section 182 for receiving a user data ?le request
`from ?rst memory 132 via data bus 133. In addition, section
`182 interprets the ADSI protocol data ?le request message
`received from terminal 110 and stored in memory device
`132 to thereby, generate a corresponding HTTP formatted
`message. The request message transmitting section 184
`receives the HTTP request message and transmits it to
`memory 134 and Web Server 150.
`Once the data ?le is located, a data ?le retrieval section
`186 retrieves the HTML data ?le from the Internet via
`memory 134 and data bus 133. Section 186 is connected to
`a data ?le formatting and transmitting section 188 that
`formats the HTML data ?le to be compatible With the
`display capabilities of screen-display 111. As explained in
`more detail beloW, this process could involve identifying
`particular sections of the data ?le for display, and
`eliminating, or truncating, those display lines that exceed the
`display capacity of screen-display 111. Preferably, the refor
`matting process involves using ADSI scripting techniques to
`con?gure the entire data ?le to a data display block speci?
`cally designed for the ADSI screen-display, and compliant
`With the ADSI protocol requirements.
`B. Internet Data Retrieval
`In order to retrieve Web pages and display them in the
`ADSI format, system 100 permits a user to access Internet
`locations through Web 140. To do this, the Internet site
`location request signals received from terminal 110 must be
`decoded by AIB 180 to a format that Web Server 150 and
`URL servers such as those at 160, 161, and 162 can interpret
`and understand. Preferably, this Would involve interpreting
`the received request message to generate a corresponding
`HTTP formatted message. Once Web Server 150 receives a
`location selection, it transmits the data ?le contained at the
`requested site location back to terminal 110 via the tele
`phony platform server, Which in this case is NAV 130. After
`NAV 130 receives the data ?le from the Internet site via the
`Web Server 150, AIB 180 formats the data ?le to an ADSI
`compatible data display block so that it may be transmitted
`to terminal 110 in a form terminal 110 can display.
`FIG. 4 shoWs a general overvieW of method 200, a call
`?oW script used in conjunction With system 1 00 for retriev
`ing an Internet data ?le from Web 140 using terminal 110.
`The subsequent ?gures, FIGS. 5—8, then shoW further details
`of the method 200 as speci?ed.
`With reference noW to FIG. 4, upon receiving a request
`from a user to access the system 100, NAV 130 determines
`if the requesting terminal 110 is an ADSI compatible device.
`(Step 210). If not, the call and process are terminated at step
`211. If terminal 110 is ADSI compatible, then using con
`ventional ADSI techniques, NAV 130 transmits a “WEL
`COME” message to terminal 110 for display on screen
`display 111. (Step 220). This informs the user that the
`connection to NAV 130 has been completed and that the user
`may commence using the features displayed. The “WEL
`COME” message may also include an individual or univer
`sal homepage from Which users begin their Internet access.
`It is contemplated that the homepage Will guide the user
`through the process described above With the commands and
`procedures that folloW.
`From the homepage or “WELCOME” screen, the user is
`permitted to make an Internet site selection (Step 230), by
`depressing a number on keypad 116 or selecting a softkey

`113 corresponding to the URL to be accessed. That is, the
`user can select Which of the available Web sites are to be
`visited and, therefore, Which data ?les Will be retrieved. As
`described above, by Way of example only,
