Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to a telecommunications system, and more particularly to using the 900-service telecommunications infrastructure to provide single-use and short term access to fee for access Internet sites. 
     2. Discussion of the Related Art 
     Some Internet Web sites, such as those for reference materials, e.g., Physicians Desk Reference, stock and investments news letters, e.g., TheStreet.com, and some newspapers, e.g., the Wall Street Journal, are intended to produce revenue in the form of charges for access to the site. Today such access charges are typically collected through a subscription process, whereby the person desiring access completes a registration form, provides a credit card number to which the access price for some period of time is charged, and receives in return an identification number/password that can be used to access the Web site. While this subscription system for charging for access is workable for individuals who expect to have continuing needs for access to a particular web site, it has certain drawbacks. 
     Granting access by subscription only is analogous to requiring individuals to take out a year&#39;s subscription to a magazine rather than paying the single copy price to satisfy their interest in a particular article that has attracted their attention. The requirement to subscribe to a particular web site similarly creates a barrier to visitation by casual users who would be willing to pay for particular items of interest, but cannot justify the cost of subscribing to the service as the cost for acquisition for that one item of information. Just as a subscription requirement would eliminate newsstand sales of magazines, the subscription mechanism for web sites puts off a whole body of potential users who might use the site as a source of a particular article, piece of information or graphic. 
     Further, the use of a credit card as the medium of payment of small charges is not cost-effective. Even if the subscription mechanism were set up for separate prices of one-time/limited time entry to web sites, the reasonable prices that might be charged for such access would, in general, be too small for credit card handling. From the users&#39; point of view, for example, there is a very large psychological barrier to giving out the information of a credit card with a $10,000 limit to an unfamiliar destination to cover a fifty cent fee. From the point of view of the web site owner, the handling overhead for hundreds of small charges is certainly daunting, if not prohibitive. 
     It is therefore highly desirable to have an alternate system for collecting fees for access to web sites that would circumvent the inherent limitations in the subscription mechanism. Such a system would both expand the potential market for web sites that are currently accessed only by subscription to include what might be a very large body of casual users who are willing to pay smaller prices for one-time access, and open up a whole new market of “admission price” web sites, which are accessed by paying a small access fee for each visit to the site. 
     One such solution, U.S. Pat. No. 5,737,414 entitled “900 NUMBER BILLING AND COLLECTION SYSTEM AND METHOD FOR ON-LINE COMPUTER SERVICES” proposes several methods to enable an on-line service provider to collect revenue from a 900-toll billing network though an access management computer. Several conceptual methods are provided, but these methods do not necessarily represent the optimum methods of connectivity for the existing 900-service infrastructure. 
     SUMMARY OF THE INVENTION 
     The method and system for utilizing 900 service for single use and short term access to internet subscription services of the present invention overcomes the limitations of the related art discussed above. 
     In accordance with one aspect, the present invention is directed to a method for using an existing caller pays service telecommunications infrastructure to provide single use and short term access to fee for access Internet web sites. The method comprising registering one or more fee for access Internet web sites with an access code handling system to generate and communicate user ID and password pairs to be used to validate payment for access to each fee for access Internet web site, provisioning one or more caller pays numbers for each registered fee for access Internet web site, and registering each provisioned number with one or more intelligent network service switches to which the provisioned numbers would be routed, routing any user originated calls by a user who desires to access the one or more fee for access Internet sites to both an automated voice response unit and a caller pays service billing system, providing the user with a session user ID via a display generated by the fee for access Internet web site, communicating via the caller pays telecommunications infrastructure a password associated with the session user ID and service option for the registered fee for access Internet web site via the automated voice response unit, and billing the user for the selected option with the caller pays service billing network. 
     In accordance with another aspect, the present invention is directed to a system for implementing an existing caller pays telecommunications infrastructure to provide single use and short term access to fee for access Internet web sites. The system comprises an access code handling system for generating and communicating user ID and password pairs to be used to validate payment for access to each fee for access Internet web site, a provisioning system for registering one or more caller pays call numbers for each fee for access Internet web site and registering each provisioned number within or more intelligent network service switches to which the provisioned numbers would be routed, a public switched network for routing any user originated calls by a user who desires to access the one or more fee for access Internet web sites to both an automated voice response unit and a caller pays billing system via the one or more intelligent network service switches, the fee for access Internet web site providing a web-based communication to the user enabling user selection of the one or more service options and generating a user ID in accordance with the user selection, the user communicating the user ID to the access code handling system via the automated voice response unit and, a network switch initiating billing for the user selection via the caller pays service billing system, and the access code handling system generating an associated password according to the password assignment protocol, wherein the voice response unit further communicates to the user, in response to receipt of a session user ID, an associated password in accordance with the protocol for the registered fee for access Internet web site, and the access code handling system communicates the user ID, the password and the service option to the registered fee for access Internet web site, and a verification device for verifying the session user ID and password provided to the user and the user ID and password communicated to the fee for access Internet web site, whereby the fee for access Internet web site enabling access to web site content upon verification. 
     In accordance with another aspect, the present invention is directed to a method for utilizing an access code handling system to control a user&#39;s access to digital data provided by an on-line server over a data network, wherein a billing system separate from the on-line server charges the user for access to the digital data. The method comprising the steps of the user receiving from the on-line server a user ID code, the access code handling system receiving, from the billing system, a message indicating that the user has requested access to digital data via the user ID code, the access code handling system communicating a password associated with the user ID code to a voice response unit, the voice response unit communicating to the user the password, and the access code handling system providing, to the billing system, indication that the password has been communicated to the user, the billing system assigning appropriate charges to the user&#39;s telephone service provider account. 
     The present invention is directed to a method and system for collecting small access fees for one-time/limited time access to web sites by capitalizing on the capabilities afforded by the combination of 900-(caller pays) long distance telephone service, and Intelligent Network Services (INS) that implement the VRUs (Voice Response Units) for 800-(called party pays) service. The method as outlined below is simple and cost effective to implement. 
     A company desiring to operate an “fee for access” web site obtains a 900-number from a long distance carrier. As is well-known, this series of numbers provides billing of the cost of the long distance call, together with a surcharge to the telephone number that originates the call. The combined costs of such calls are then reported and collected on the telephone bill of the caller who originated them. From the amount collected, the long distance carrier consolidates collections, deducts a charge for the call and a portion of the surcharge, and passes all the rest of the money collected on to the 900-number subscriber. 
     In accordance with the present invention, the long distance carrier then sets up routing of that particular 900-number through an INS VRU module that is capable of receiving digits dialed from a telephone and producing a voice response. The 900-number VRU module is also supplemented with an interface to an access code handling system that: (a) can automatically maintain a data base comprising a set of x-digit codes representing user identification numbers, and associated y-character alphanumeric codes representing the assigned passwords for active users; and (b) can effect data transfer to the host system for the “fee for access” web site, to update the host copy of that data base, or receive and validate an x-digit/y-character pair sent from the host web site. 
     When individuals log into the web site, they are informed via displays on the home page that the site is an “fee for access site”, and further access will cost z cents. When the individuals assent to that charge, they are further informed that their user identification number is x, and that they are to call the 900-number to obtain a password for access to the web site. 
     When the call to the 900-number is placed, it is answered by a voice response unit that instructs the caller to enter the x-digit number just obtained from the web site. The number is entered by dialing it, in the same way, for example, as credit card numbers are entered in response to voice recordings. 
     Upon receipt of the x-digit number and verification that it is valid for use, the access code handling system generates a y-character password that is automatically transmitted back to the web site host, or alternately has been transmitted earlier to a web site data base, for checking by the web site host. The y-character password is then played by the VRU, and thereby conveyed orally to the caller seeking the password. 
     The individual desiring access to the “fee for access” web site has then paid for, and may use, the combination of the x-digit identification number obtained from the web site and the y-character password obtained from the 900-call to the VRU to log onto the web site. 
     Each log-on with that x-digit/y-character pair can then be monitored with commonly used password protection software until the agreed term of the admission to the web site (as defined, e.g., by the number of log-ons allowed with a particular combination or date of expiration) has expired, at which time the x-digit/y-character combination is invalidated. 
     The call handling systems for 900-calls and effecting the VRUs are both fully in place in the networks of major long distance carriers like MCI WorldCom. The system that should preferably be added to the existing INS capabilities to support the method just described comprises a software module, referred to here as an access code handling system, that interfaces with the VRU controller. This access code handling system preferably: (a) maintains a data base of user identification numbers and passwords for each of the different 900-numbers via which admission fees are collected for “fee for access” web sites; (b) receives communications from the VRUs identifying which x-digit codes need passwords; (c) communicates the associated y-character passwords to the VRUs for generation of the voice announcements; and (d) effects data communications between itself and the “fee for access” web site host systems supported to either automatically update a host-resident data base of active x-digit/y-character pairs, or respond to calls from the host systems for log-on verification. 
     The system and method of the present invention provide for rapid payment and access to pay to view Web sites. No credit card, charge card or debit card access is required and individuals do not have to sign up for extended subscription periods.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Certain web sites require an admission fee. Essentially, these web sites require an individual desiring to browse the site to pay to view. When an individual accesses a pay to view web site, he or she is typically directed to a registration area. There the individual is required to answer various questions and to provide a charge or credit card number so that the registration fee may be automatically charged thereto. As explained above, there are drawbacks to this type of system. Accordingly, the individual or organization to which the web site belongs may provide a system whereby visitors to a pay to view web site can pay each time they access the site, or alternately, a system whereby single view or infrequent visitors can pay each time they access the site and frequent visitors can pay as described above. 
     An organization that owns or provides a pay to view web site applies for a caller pays number from a long distance carrier, such as MCI WorldCom. When an individual accesses a pay to view web site, he or she is given an identification code and instructions to call the caller pays number. At this point, the individual desiring access has not yet paid for anything. When the individual calls the caller pays number, a voice response unit prompts the caller for his/her identification code which is verified and correlated to a password by an access code handling system. The voice response unit provides a user password, supplied by the access code handling system, to the caller and terminates the call. Armed with the identification code and the password, the individual goes back to the web site and enters the code/password combination which was automatically activated via the caller pays call. 
     The owner/provider of the web site receives remuneration for access to the web site via the caller pays call and the individual seeking access to the web site is charged for access via his/her normal telephone bill. In addition, the long distance carrier providing the caller pays service also receives remuneration for the telephone call. 
     The duration of web site access based on the caller pays call may vary, and various prompts by the voice response unit may provide number of access options. 
     As illustrated in FIG. 1, a non-subscribed visitor to a web site  15  utilizes a conventional personal computer  10  to seize a local line  11  into the Public Switched Telephone Network (PSTN)  20 , which sets up end-to-end telephone calls. The PSTN  20 , then sets up a telephone connection  21 , to the Internet Service Provider  25  used by the caller. The Internet Service Provider then takes the telephone signals received from the computer  10  via the telephone circuit  21  and converts the data they carry into the form and addressing used by the packet-switched data network  30 , commonly referred to as the Internet. Converted data from the Internet Service Provider is then forwarded to the host/server  40  for the destination web site  15 . As shown in FIG. 1, it is understood that multiple “fee for access” web site host systems  15   a , . . . ,  15   n  may be supported by the present invention. 
     When the non-subscribed visitor connects to the web site  15  via the routes shown and communicates via the computer  10  a desire and willingness to pay for access, the web site communicates to the computer a user identification code, together with instructions as to how to obtain the password associated with that user identification code, generated and maintained in an access code handling system  70 . The instructions communicated to the computer  10  include a 900-(caller pays) number to be called to obtain the corresponding password. 
     The non-subscribed visitor then goes to an ordinary push-button telephone  50  and seizes a local line  51 , which may also be the line  11 , used earlier by the computer  10 , to place the 900-service call through the PSTN  20  to a long distance carrier Intelligent Network Switch (INS)  60 . Until and unless that call is placed there is absolutely no charge to the visitor for having attempted to browse the web site  15 . 
     When the PSTN  20  connection to the INS is effected via the circuit  22 , the INS  60  passes information to the long-distance 800-/900-billing system  61  as to how the call is to be charged and switches the connection from the telephone  50  to a second circuit  23  connecting the telephone with the Voice Response Unit (VRU)  62 . It is understood that conventional 900-number provisioning techniques may be implemented for enabling intelligent network switches to route the 900-number call with the appropriate associated automated voice response unit message. The VRU  62  then communicates over the telephone connection  23  the voice prompts and instructions for requesting an access password for the web site  15 . Included among those instructions is a prompt for the caller to enter via the telephone  50  key pad the user identification number received by the computer  10  from the Web site  15  via the Internet  30  PSTN  20  connections  31  and  21 , respectively. Upon receipt and verification of the kind of access sought and the necessary user identification number, the VRU  62  communicates any necessary ancillary billing information to the long distance 800-/900-billing system  61  and communicates the user identification number to the access code handling system  70 . 
     Either at the time of the receipt of the message comprising the user identification number, or earlier, in anticipation of a user of that identification number, the access code handling system communicates the identification number/password pair to the web site  15  via an Internet connection  32  and the Web site host/server  40 . When contacted by the VRU  62  maintaining the connection to the telephone  50 , the access handling system  70 , communicates the password associated with the user identification number to the VRU  62 , which generates a voice message back to the caller&#39;s telephone  50  via PSTN  20  circuit  23 . Once the necessary information is communicated by the VRU  62 , the PSTN  20  circuit  23  connecting the VRU  62  and the telephone  50  is disconnected, allowing its use for other purposes, including originating of data calls via the computer  10 . 
     The non-subscribed user then uses the computer  10  to communicate via a PSTN  20  circuit  21  to the Internet Service Provider  25 , and an Internet  30  circuit  31  via the web site host/server  40  to the web site  15 . In the exchanges between the web site  15  and the computer  10 , the user is prompted to enter the user identification number obtained from the web site  15  and password obtained from the Access Code Handling System  70  via the Voice Response Unit  62 . The matched pair is checked by the web site  15  against valid access code information received from the Access Code Handling System  70 . Verification that the two parts match and the user has not exhausted the number/period of accesses associated with the matched user identification/password pair allows the caller to browse the web site  15  from the computer  10 , or any other computer capable of communicating through the Internet  30 . 
     It should be understood that the present invention includes a software module, embodied in the access code handling system, interfacing the VRU controller that: 1) maintains a database  16  (FIG. 1) including the user identification numbers and passwords for each of the different provisioned 900-numbers via which admission fees are collected for the “fee for access” web site; 2) receives communications from the VRUs identifying which x-digit codes need passwords; 3) communicates the associated y-character passwords to the VRUs for generation of the voice announcements; and 4) effects data communications between itself and the “fee for access” web site host systems supported to either: automatically update a host-resident database of active x-digit/y-character pairs, or respond to calls from the host systems for log-on verification. 
     A preferred methodology  100  for providing a non-subscribed user single and short term access to Internet web-sites is now provided in view of FIGS.  2 ( a ) and  2 ( b ). 
     In FIG.  2 ( a ), as indicated at a first step  103 , a user accesses the desired web site. In response, at step  106 , a message is displayed on the web site home page informing the user that the site is an “fee for access” site, and may include an admission fee schedule for single-use or limited short term access. For example, a display may indicate single-use access may cost z cents. At this point, the user may agree to the displayed charges at step  107 , or leave the web site as indicated at step  109 . If the user decides to pay for web site access, the web site host queries a data base (not shown) at step  110  to retrieve an unassigned x-digit user ID number. The user is then informed that their user identification number is x, and that they are to call the 900-number to obtain a password. Additionally, a flag stored in memory and associated with that number is set to indicate that the user ID number is assigned. Then, at step  113 , a web page communication is displayed at the user terminal indicating the 1-900 number, the assigned ID number and instructions enabling the user to proceed to access the associated billing system. As instructed, at step  117 , the user dials the 1-900 number via a standard telephone. When the call to the 900-number is placed, it is answered by a voice response unit at step  120  that instructs the caller at step  123 , to enter the x-digit user ID number just obtained from the web site. It is understood that the system also bills charges to the calling number in accordance with the long-distance 800-/900-billing system implemented. The user then enters the assigned ID number by dialing it, in the same way, for example, as credit card numbers are entered in response to voice recordings, i.e., via a telephone keypad, as indicated at step  126 . Then, at step  129 , the VRU system records the entered x-digit user ID number and, at step  131  communicates the x-digit user ID number to the access code handling system as described herein with respect to FIG.  1 . As indicated at step  135  and step  138  (FIG.  2 ( b )), upon receipt of the x-digit number and verification that it is valid for use, the access code handling system generates or retrieves a y-character password that is or had earlier been automatically transmitted back to the web site host along with the corresponding x-digit ID number, where the x-digit/y-character pair is stored in the web site host for purposes of validating accesses. 
     Concurrently, as indicated at step  141 , the y-character password is transmitted to the VRU and conveyed orally to the caller seeking to use it, as indicated at step  143 . The non-subscribed user desiring access to the “fee for use” web site which has been paid for in accordance with a protocol for the now requested ID code/password pair, may use the combination of the x-digit identification number obtained from the web site and the y-character password obtained from the 900-call from the VRU to log onto the web site, as indicated at steps  145 ,  148  and  150 . Particularly, at step  153 , the non-subscribed user enters his/her x-digit identification number and y-character password pair via the user&#39;s terminal and is admitted to the web site at steps  155 ,  157 . The user is subsequently able to browse, copy and/or download content from the web site as indicated at step  160 . If only single-use access was paid for, once the user exits the site, at step  165 , he/she may no longer access the site unless the user ID assignment process described herein is repeated. However, if the multiple access option was paid for, the user may subsequently re-enter and log into the web site by returning, as indicated by line  169 , to the web site log in step  153 . 
     The y-character password and the x-digit user ID number may be any suitable length and may comprise any combination of alpha-numeric characters. For security reasons, the length of the password may be longer than the length of the ID number. 
     Although shown and described is what are believed to be the most practical and preferred embodiments, it is apparent that departures from specific methods and designs described and shown will suggest themselves to those skilled in the art and may be used without departing from the spirit and scope of the invention. The present invention is not restricted to the particular constructions described and illustrated, but should be construed to cohere with all modification that may fall within the scope of the appended claims.
