Full Description:
TECHNICAL FIELD  
   The present invention relates to computer managed communication networks of interactive display stations, such as the World Wide Web (Web) or like private networks, and particularly to applications of such networks for user interactive monitoring of telephone conferencing. 
   BACKGROUND OF RELATED ART  
   The past decade has been marked by a technological revolution driven by the convergence of the data processing industry with the consumer electronics industry. The effect has, in turn, driven technologies that have been known and available but relatively quiescent over the years. A major one of these technologies is the Internet or Web related distribution of documents. The Web or Internet, which had quietly existed for over a generation as a loose academic and government data distribution facility, reached “critical mass” and commenced a period of phenomenal expansion. With this expansion, businesses and consumers have direct access to all matter of documents and media through the Web. 
   Also, because of this extensive access of businesses and consumers to the Internet or Web (used interchangeably herein), it is highly likely that anyone who might be asked to participate in a telephone conference would also have access to the Web. Such demographics has led the industry to seek applications in which the Web could be used in telephone conferencing. The present invention considers one such potential application. 
   The use of telephone conferencing in commerce and industry has undergone some changes that were not anticipated a decade ago. At that time, the trend appeared to be toward teleconferencing between sets of high technology studios each with groups of people and closed circuit television therebetween. While some of these set ups are still quite active, the business world appears to have moved back to a more basic and less expensive telephone conferencing in which individuals and remote telephone stations, each with either single attendees or conferees or groups of people over speaker phones participate in the telephone conference. This rather basic telephone conferencing has been proliferating world-wide driven by the economic and terrorist fear curtailment of travel. 
   While this form of telephone conferencing has been used quite effectively to save time and money, participants, i.e. conference attendees, have encountered some problems. First, during the initiation of the telephone conference, time is wasted as the participants connect on one by one until the quorum of requisite attendees is connected. Then, when several people are talking over the lines during the same time period, it is hard for each attendee to know who is who. Likewise, it is hard for the conference host or any other interested party to know when a required attendee has disconnected. 
   SUMMARY OF THE PRESENT INVENTION 
   The present invention provides a system for monitoring such teleconferencing that reduces the above-mentioned problems. The invention is directed to the monitoring of any conventional telephone conference in which a requisite set of conference attendees respectively at a corresponding set of telephone stations are connected into a telephone conference. The invention provides in association with the telephone conference, a communication network with user access via a plurality of data processor controlled interactive display stations for displaying received network documents available from sources on the network in which there is an interactive display station associated with each of said set of telephone stations with a displayed document including an indicator representing each attendee having means for indicating whether the attendee&#39;s telephone station is connected into the conference, and means for indicating whether the attendee is speaking. 
   The present invention also provides some valuable expedients for initiating such telephone conferences involving the combination of means (during the initiation period) for placing on-call each telephone station initially connecting into the conference, and means for calling these on-call telephone stations into the conference when a quorum of said requisite attendees has connected into the conference. This initiation process may be automated through means for determining when the quorum of required attendees has connected into the conference, and rendering the means for calling the on-call telephone stations automatically responsive to the means for determining when said quorum has connected.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   Referring to  FIG. 1 , a typical data processing system is shown that may function as the computer controlled network terminals or Web stations used for the display of the screen pages or panels supporting the telephone conference. The system shown is also illustrative of any of the server computers used for the Web page or panel distribution to be described in greater detail with respect to  FIG. 2 . 
   A central processing unit (CPU) 10, may be one of the commercial microprocessors in personal computers available from International Business Machines Corporation (IBM) or Dell Corporation; when the system shown is used as a server computer at the Web distribution site to be subsequently described, then a workstation is preferably used, e.g. RISC System/6000™ (RS/6000) series available from IBM. The CPU is interconnected to various other components by system bus  12 . An operating system  41  runs on CPU  10 , provides control and is used to coordinate the function of the various components of  FIG. 1 . Operating system  41  may be one of the commercially available operating systems such as the AIX 6000™ operating system available from IBM; Microsoft&#39;s Windows XP™ or Windows2000™, as well as UNIX and AIX operating systems. Application programs  40 , controlled by the system, are moved into and out of the main memory Random Access Memory (RAM)  14 . These programs include the programs of the present invention for the monitoring of telephone conferences on display station screen panels ancillary to and supportive of associated telephone stations connected in the telephone conference. 
   In the examples to be described, we will use the Web for the distribution of the monitoring display panels at the Web stations. Any conventional Web browser application program, such as Microsoft&#39;s Internet Explorer™, or Lotus Notes™ Personal Web Navigator or Server Web Navigator will be available for distributing the monitoring Web pages or panels to the network stations associated with the telephone conference stations. A Read Only Memory (ROM)  16  is connected to CPU  10  via bus  12  and includes the Basic Input/Output System (BIOS) that controls the basic computer functions. RAM  14 , I/O adapter  18  and communications adapter  34  are also interconnected to system bus  12 . I/O adapter  18  communicates with the disk storage device  20 . Communications adapter  34  interconnects bus  12  with the outside network enabling the computer system to communicate with other such computers over the Web or Internet. The latter two terms are meant to be generally interchangeable and are so used in the present description of the distribution network. I/O devices are also connected to system bus  12  via user interface adapter  22  and display adapter  36 . Keyboard  24  and mouse  26  are all interconnected to bus  12  through user interface adapter  22 . It is through such input devices that the user at a receiving station may interactively relate to the Web in order to access Web documents. Display adapter  36  includes a frame buffer  39  that is a storage device that holds a representation of each pixel on the display screen  38 . Images may be stored in frame buffer  39  for display on monitor  38  through various components, such as a digital to analog converter (not shown) and the like. By using the aforementioned I/O devices, a user is capable of inputting information to the system through the keyboard  24  or mouse  26  and receiving output information from the system via display  38 . 
   Before going further into the details of specific embodiments, it will be helpful to understand from a more general perspective the various elements and methods that may be related to the present invention. Since an aspect of the present invention is directed to documents such as screen panels transmitted over networks, an understanding of networks and their operating principles would be helpful. We will not go into great detail in describing the networks to which the present invention is applicable. Reference has also been made to the applicability of the present invention to a global network, such as the Internet or Web. For details on Internet nodes, objects and links, reference is made to the text,  Mastering the Internet,  G. H. Cady et al., published by Sybex Inc., Alameda, Calif., 1996. The Internet or Web is a global network of a heterogeneous mix of computer technologies and operating systems. Higher level objects are linked to the lower level objects in the hierarchy through a variety of network server computers. E-mail is distributed through such a network. 
   A generalized diagram of a portion of the Web for illustration of the telephone conferencing and monitoring system of the present invention is shown in  FIG. 2 . The telephone conference may be a conventional teleconference set up with a plurality of remote telephone stations  25 ,  26 ,  27  and  28  through which the invited conference attendees call-in or are called-in and are interconnected through standard Public Switched Telephone Networks (PSTNs)  23  in a standard manner. The telephone stations may be conventionally wired into the conference through the PSTNs or the stations may be wireless cellular telephone stations connected into the PSTN through conventional wireless cellular networks. Each telephone station  25 – 28  has an associated Web network terminal  11 ,  13 ,  15  and  17  with displays  57  upon which the screen panels  56  may be displayed. Terminals  11 ,  13 ,  15  and  17  may be implemented by the computer system setup in  FIG. 1 , and connection  58  ( FIG. 2 ) is the network connection shown in  FIG. 1 . For purposes of the present embodiment, terminals  11 ,  13 ,  15  and  17  are representative of the Web display stations for respectively supporting and monitoring telephone stations  25 – 28  to be described with respect to  FIGS. 3 through 6 . Reference may be made to the above-mentioned,  Mastering the Internet,  pp. 136–147, for typical connections between local display stations to the Web via network servers; any of which may be used to implement the system on which this invention is used. In the typical set up shown, terminals are connected via, let us say, host dial connections (not shown) to server  45  provided by a Web Service Provider or the private network service provider that in turn accesses the Web  50  via connection  51  to a Web access server  53  and connection  61 . In addition to the above-described standard dial-in or dial-out in the establishment of telephone conferencing, the Web or like browser program may be modified with application programs that will dial telephone stations. The possibility of such an alternate dialing is indicated in the lines connecting telephone stations  25 – 28  to their associated network terminals in addition to the lines connecting these telephone stations to the PSTN  23 . 
   With this Web network distributed monitoring set, there will now be described an embodiment for monitoring telephone conferences using the distributed Web page set up and monitoring panels of  FIGS. 3 through 6 . The host who is setting up the teleconference uses the dialog panel of  FIG. 3  to submit a profile of each attendee. At this point, we assume that the host has already cleared meeting times and scheduling with these attendees using conventional conference techniques such as those used in Lotus Notes, Version 6, Meetings and Conferencing. These procedures are not part of this invention that deals with the provision of monitoring panels. Thus, when the host is making entries on the set up dialog panel  70  of  FIG. 3 , the subject and time of the meeting  79  has already been set. For each attendee  71 , the host enters the name  72 , the organization  73 , the telephone number  74  and whether the attendee is required  75  or optional  76 . The host is also prompted to enter a short biography  77  of the attendee. This information is stored at the host&#39;s display station or its associated network server. From this information, there is generated a Web page or panel  80 ,  FIG. 4 , that is distributed over the Web to all attendees for the conference at the time that dial in for the conference has been scheduled. The status shown in  FIG. 4  is the Idle mode  85  wherein call-ins on the telephone stations have not yet commenced. Panel  80  has a set of circular icons  83  representing each required attendee and pentagonal icons  84  representing optional attendees. For each invited attendee, there is given the name  81 , as well a brief descriptive or biographical text. The conference itself is represented by icon  82 . 
   As the attendees begin to dial into the teleconference as shown in  FIG. 5 , the connection of the attendee into the conference is indicated by a highlighting  86 , e.g. a lighting up or brightening of the icon representing the attendee. Also, during the initial call-in period, if all of the required attendees have not as yet called in, then the indicated conference status  85  changes to On-hold wherein the connected attendees need not wait on the line at the telephone. Rather, when the last required attendee calls in and is connected to complete the conference, then the telephones of all the on-hold attendees ring and the conference commences. This may be done automatically. 
   In  FIG. 6 , the initiation of the conference is over; the status  85  is Active and the four required attendees are connected  86 . One of the optional attendees is connected  88 . As an aid to the attendees, when an attendee is speaking, his connected icon  86  flashes or pulses  87 . If any attendee disconnects during the conference, his icon will return to its initial unhighlighted state  83  ( FIG. 3 ). 
     FIG. 7  is a flowchart showing the development of a process according to the present invention for enabling telephone conference attendees to monitor such conferences over screen panels distributed to them over a communication network. In a private or public communication network, such as the Web, there is set up a system enabling the teleconference attendees to monitor by associating with each telephone station in the conference, a corresponding network display station for monitoring the teleconference, step  90 . The conference host is provided with a set up panel enabling him to designate optional and required attendees and provide a brief description of each attendee, step  91 . There is set up a process enabling the host to provide to each telephone conference attendee, a network, e.g. Web page describing each attendee, visually indicating whether the attendee is connected into the teleconference and whether the attendee is speaking, step  92 . A procedure is provided for teleconference initiation that enables the attendees to telephone conventionally into the conference and thereby be connected. The connection status of each attendee, according to step  92 , is indicated, step  93 . During the initiation period of step  93 , there is provided an on-call status wherein the connection status of each called-in and connected attendee is indicated but the attendee is free to do other functions until all required attendees are connected, step  94 . Finally, an implementation is provided for notifying all on-call attendees that a quorum of the required attendees has been reached in step  94  and for assembling all such attendees into the teleconference, step  95 . 
   A simplified run of the process set up in  FIG. 7  and described in connection with  FIGS. 3 through 6  will now be described with respect to the flowchart of  FIG. 8 . The conference host is prompted and enters the data regarding attendees that is required to create the attendee monitoring screen panels, step  100 . The panels generated by the data entered by the host in step  100  is distributed to all attendees, step  101 . At the appointed time, initiation of the conference commences by standard telephone calls, step  102 . During conference initiation, a determination is made as to whether an attendee is connected, step  103 . If Yes, the attendee&#39;s icon on each monitoring panel is lit up, step  104 . Then, or if the decision in step  103  is No, a determination is made, step  105 , as to whether all required attendees have been connected, step  105 . If No, then, step  106 , all connected attendees remain on-call and the process is returned to step  103 . If Yes in step  105 , then the on-calls are assembled and the conference is begun, step  107 . During the teleconference, a determination is made as to whether an attendee is speaking, step  108 . If Yes, the speaking attendee&#39;s icon is flashed. Then, or if No, a determination is made as to whether a particular attendee has disconnected, step  110 . If Yes, the attendee&#39;s icon is turned off, step  111 . Then, or if No, a determination needs to be made as to whether the host has ended the conference, step  112 . If Yes, the conference is exited. If No, the process is returned to step  108 . 
   One of the preferred implementations of the present invention is in application program  40  made up of programming steps or instructions resident in RAM  14 ,  FIG. 1 , of Web server computers during various Web operations. Until required by the computer system, the program instructions may be stored in another readable medium, e.g. in disk drive  20 , or in a removable memory, such as an optical disk for use in a CD ROM computer input, or in a floppy disk for use in a floppy disk drive computer input. Further, the program instructions may be stored in the memory of another computer prior to use in the system of the present invention and transmitted over a Local Area Network (LAN) or a Wide Area Network (WAN), such as the Internet, when required by the user of the present invention. One skilled in the art should appreciate that the processes controlling the present invention are capable of being distributed in the form of computer readable media of a variety of forms. 
   Although certain preferred embodiments have been shown and described, it will be understood that many changes and modifications may be made therein without departing from the scope and intent of the appended claims.
