Definitions

  • the present invention relates to a method and apparatus for handling a communication between two or more parties using a computer accessed by way of a communication network. More particularly, the invention relates to a method and apparatus for receiving a communication from a sender for a recipient, storing the communication as a record in a searchable computer, sending notification to the recipient that the communication was received, receiving a request from the recipient to obtain the communication, delivering the communication to the recipient over the communication network, and sending an acknowledgement to the sender that the communication was received by the recipient.
  • the acknowledgement may also include a data or transaction record including the time and date the communication was stored and the time and date the communication was received by the recipient.
  • Senders of communications often desire to receive notification that their communications were actually received by the recipient. Further, senders of communications often wish to establish the date and time that the communication was sent and received. For example, communications such as cancellation notices and legal notices require that the recipient respond thereto within a certain time period. The senders of these communications need to receive notification that the communications were indeed received so that they can attempt to redeliver the communications if they were not received.
  • certified mail provides the sender of a communication with an acknowledgement that the communication was delivered to or picked up by the recipient.
  • conventional certified mail does not establish a record of the content of the message and therefore does not provide sufficient proof that the message content was received by the recipient.
  • certified mail is slow because the communication must pass through the conventional mail system and then be either hand-delivered directly to the recipient or stored at a post office until the recipient picks up the communication. Often, several delivery attempts must be made before the certified letter is either delivered or returned to the sender.
  • Certified mail is also relatively expensive due to the labor costs associated with shipping, storing, delivering and redelivering of the communications.
  • Electronic mail has solved the speed problems associated with conventional mail because it allows communications to be digitized and transmitted electronically from one computer to another over a communication network such as a local area network (LAN) , wide area network (WAN) , or the Internet.
  • LAN local area network
  • WAN wide area network
  • electronic mail does not provide the sender of a communication an acknowledgement that a certain communication was actually received by the recipient.
  • the sender of a communication does not know for certain whether his or her communication was received and the time and date the communication was received.
  • the present invention overcomes the problems outlined above and provides a distinct advance in the state of the art. More particularly, the present invention provides an improved method and apparatus for providing the sender of a communication an acknowledgement that the communication was received by the recipient and that the communication was sent and received on a certain date at a certain time. Additionally, the present invention provides a communication handling method that is faster and less expensive than conventional certified mail services.
  • the preferred communication handling method is implemented on a communication handling apparatus including a central communication handling computer, a plurality of access terminals, and a communication network coupling the communication handling computer with the access terminals.
  • the communications handling computer is preferably a file server type microcomputer including conventional memory for receiving and storing communications.
  • the access terminals are preferably IBM compatible microcomputers including means for allowing users to transmit communications and requests to obtain communications to the central communications handling computer and obtain previously stored communications. Communications and requests to obtain communications can also be sent to the central communications handling computer by way of digitized facsimile transmissions, voice transmissions, or combined video and audio transmissions.
  • the communication network couples the communications handling computer with the access terminals for providing communication therebetween.
  • the communication network is preferably a telecommunication network.
  • the method of the present invention is preferably implemented in the form of a computer program for operating the communications handling computer of the communication handling apparatus.
  • the method broadly includes the steps of receiving into the communications handling computer a communication from a sender for a recipient sent over the communication network, sending the communication to the recipient over the communication network, and sending an acknowledgement to the sender that the communication was received by the recipient and that the communication was sent and received on a certain date and time.
  • the invention further includes the steps of notifying the recipient of the receipt of the communication in the communication handling computer and receiving into the computer a request from the recipient to obtain the communication.
  • the communication may be stored in the central computer with "public key” coded identification information for identifying the recipient. To retrieve the communication, the recipient must enter his or her corresponding "private key” coded identification information. In this way, the communication can be encrypted so that only the proper recipient can retrieve the communication.
  • the above described method and apparatus for handling communications offers numerous advantages. For example, by providing a method for sending a communication to a recipient and sending a corresponding acknowledgement to the sender that the communication was received by the recipient, senders can be notified that their communications were actually received. This is particularly useful for communications that require a response within a specified time because the sender won't have to repeatedly resend the communication until a response is received;

  • the program then moves to step 104 where it displays the options "Register Communication?” and “Request Delivery of Communication?” and prompts the user to select one of the options to continue.
  • Step 106 determines whether the option "Register Communication" was selected. If the answer to step 106 is yes, the program proceeds to steps 108-122 for prompting the user to register his or her communication. If the answer to step 106 is no, the program proceeds to step 200, of Fig. 2B as described below.
  • Step 108 prompts the user to enter a communication.
  • the program may limit the length of the communication or may allow a communication of unlimited length as a matter of design choice.
  • Step 110 then asks whether the user wishes to receive an acknowledgement that the communication was requested by or delivered to the recipient. This option allows the sender of a communication to send either conventional communications or return receipt communications. If the answer to step 110 is no, the program proceeds to step 120 as described in more detail below.
  • step 110 the program proceeds to step 112 which prompts the sender of the communication to enter his or her contact address such as an e-mail address.
