Definitions

  • the present invention relates to facsimile transmission routing systems and more specifically, the present invention relates to a facsimile data transmission system and process which optimizes transmission routing for either long distance cost savings or delivery urgency considerations without the requirement of any special hardware connected to the sender's facsimile machine.
  • Facsimile transmission systems are known. In the past these systems, which were primarily directed at the long distance market, were established with the hope of attracting customers by offering a cost saving alternative over direct long distance dialing.
  • the sender is provided with a "black box" which is installed on the facsimile line between the facsimile machine and the telephone line.
  • Faxing is now an essential component in many business activities. Facsimile messages are generally sent via an apparent direct telephone link from the sender's facsimile machine to a receiving facsimile machine.
  • the receiving facsimile machine may be a personal machine or a central terminal where messages are sorted and redistributed to the correct destination.
  • Another approach to securing transmission is the use of "mailbox" functions whereby, instead of received facsimiles being immediately printed out at the destination machine and open to public inspection, the received facsimiles are stored in an electronic mailbox and can only be retrieved by a recipient having the security code to enter the mailbox (conventionally a Personal Identification Number (PIN)).
  • PIN Personal Identification Number
  • facsimile messages are generally sent over the most direct telecommunication lines available at the time of sending.
  • This apparent direct connection is not always the cheapest connection available, especially if the facsimile being transmitted is not necessarily of an urgent nature.
  • a "time delay" transmission option is available on many facsimile systems. This "time delay" option allows a sender to select a convenient time to send the facsimile document when telephone rates are at their lowest. This is a particularly useful feature when long distance/international calls have to be placed and economy is at a premium.
  • the sending facsimile machine is generally connected to the receiver via the most direct lines available, these not necessarily being the most economical. Facsimile transmission systems which attempt to overcome some of the problems of the apparent direct link are known in the art.
  • United States Patent No. 4,994,926 to Gordon et al. discloses a facsimile telecommunication system, compatible with existing facsimile terminal machines, which provides a computer-based facsimile store and forward facility (SAFF) as an integral part of a switched telephone network system. All facsimile transmission entered onto the network are routed to a SAFF which is typically located in the general geographical area of the originating machine. The transmissions are temporarily stored at the SAFF in a mass storage media. A subscriber to the system sends an outgoing facsimile message to the SAFF with which it is associated. The SAFF records the facsimile message together with data as to originating facsimile machine and destination facsimile machine. The SAFF facility then delivers the facsimile message to the intended receiving facsimile machine, either directly or through another SAFF facility. If unsuccessful on initial attempt, the SAFF periodically retries to send the facsimile message.
  • SAFF facsimile store and forward facility
  • each subscriber is assigned a mailbox on their local SAFF. Destination (outgoing) facsimiles are stored in the mailbox and the subscriber may periodically access the mailbox using a PIN number to receive waiting facsimiles or redirect stored facsimiles to another destination.
  • Gordon et al. further discloses that the system may be provided with a facsimile to a voice message conversion system, which converts inbound facsimile messages to voice mail messages which are stored in destination voice mailboxes.
  • Gordon et al. further disclose a process of establishing connections between SAFFs where an inbound control unit imposes an algorithm on each incoming facsimile document which examines the destination numbering and the available telephone trunk line resources and chooses the most efficient combination of these lines for routing the facsimile.
  • United States Patent No. 4,941,170 to Herbst discloses a facsimile transmission system to transmit documents over telephone lines using an electronic mail system.
  • the electronic mail system may be localized or distributed. Transmission is initiated by the sending facsimile machine transmitting a mark sense cover sheet, which has a mark sense identifier printed on it, to a facsimile controller.
  • the facsimile controller checks for the presence of the mark sense identifier and, if present, the controller reading the identifying information and destination address coded thereon. The controller then transmits the identifying information and destination address and the subsequently received document facsimile data to the electronic mail system in digital form, for retransmissions back through the same or a different controller to one or more receiving facsimile machines.
  • United States Patent No. 5,287,199 to Zoccolillo discloses a facsimile message processing and routing system in which a processor, connected to a communications switching system, intercepts each facsimile message destined for a receiving party.
  • the processor analyzes at lea,st a portion of each intercepted message to collect routing information and call number.
  • the processor then delivers the message to at least one of a plurality of other destination facsimile terminals, based on die routing information gathered from the message and prearranged routing information stored in the processor and provided by the receiving party.
  • a facsimile message delivery system in which messages sent over a telephone system are subjected to prespecified actions at a facsimile receiving station.
  • the sender initiates a call to the facsimile receiving station by dialing a telephone number which is sufficient to route the telephone call to the facsimile receiving station and which is also sufficient to determine the prespecified actions to which the facsimile message is to be subjected at the receiving end.
  • the telephone number is carried through the telephone system in the form of an address signal as part of the call initiation process.
  • the facsimile receiving station has information stored thereon which associates with each possible incoming telephone address signal, a prespecified action to be taken with respect to that call.
  • the facsimile receiving station uses the stored information to determine what actions should be taken for the incoming message. Once received, the incoming message is handled in accordance with the prespecified action.

  • a network of RADBs 22 may be established to handle the increased routing and scheduling requirements.
  • a discreet number of POPs 14 will communicate directly to one preassigned RADB 22.
  • RADB 22 may be configured as a fully redundant system similar to that described with respect to POP 14 in order to prevent total system failure in the event of a malfunction. The method of scheduling and arbitrating facsimiles will be described in greater detail below.
  • RADB 22 An alternative arrangement of RADB 22 would be to separate the traffic handling requirements to a communication hub and to reserve the function of RADB 22 to that of routing and scheduling.
  • Billing and financial database 24 is a processing means which largely handles the business management aspects of system 10. For example, facsimile routing policy objects, routing rate information, service policy objects, customer billing, subscriber contracts, and administrative POP 14 management functions are managed by BFDB 24. As an example of the functionality of BFDB,

  • the present invention is in no way limited to the data entities depicted in Appendix A as entities may be added or removed depending on the management structure and availability of resources of system 10.
  • Appendix B is a glossary describing the functionality of each of the data entities described graphically in Appendix A.
  • SIGNALING MEANS One requirement of the subscriber using system 10 is that each facsimile transmitted be accompanied by a signaling means.
  • the signaling means indicates to system 10 a plurality of information for use by the system, including but not limited to, data such as: the facsimile number of DFM 34; transmission options; authorization code; and administrative information such as subscriber identification number, predefined destination list and/or predefined facsimile documents.
  • the signaling means is in the form of a key page 200, as illustrated in Figures 3a or in an alternative in Figure 3b.
  • key page 200 is attached to the facsimile as a leading page, placed ahead of a conventional cover page.
  • keypage 200 comprises a plurality of data boxes in which, the subscriber is to enter a plurality of data, as indicated above.
  • keypage 200 includes: a dialing digits data box 204; an authorization code data box 208; a time constraints data box 212; and, optionally, a known destination list data box; and a known documents data box (not shown).
  • At least one registration means 202 arranged in a predetermined manner proximal the top and bottom edges of keypage 200.
  • the at least one registration means 202 is preferably in the form of a graphical icon which, in the case of Figure 3, is depicted as a small square.
  • Registration means 202 is employed to alert system 10 that a facsimile is about to be received and to indicate the orientation of the keypage in SFM 28. Orientation of keypage 200 is a significant concern as system 10 requires some means to indicate how the data is to be read by FPOP 14.
  • Key page 200 further includes a subscriber identifier means 210 which, as shown in Figures 3a and 3b is a bar code. Subscriber identifier means 210 is employed to identify data to system 10 representing the validity of the subscriber employing key page 200.
  • keypage 200 may include data representing a time expiry limit on the keypage. If system 10 detects that keypage 200 has expired, the facsimile will not be authorized for transmission.
  • data contained in subscriber identifier 210 is compared with authorization code 208 to determine the validity of the subscriber attempting to employ system 10.
  • the plurality of data boxes are fashioned to resemble a grid and are sized to permit entry of the required length of data per data item.
  • dialing digits data box 204 which contains data representing the destination facsimile number, is sized to accommodate a maximum of a 24 digit number which enables the subscriber to accommodate any long distance number including country code, area code and actual destination number. Therefore, as indicated by the Figure 3, dialing digits data box 204 would be formatted as a grid 24 columns wide by 14 rows in height. As would be apparent to those of skill in the art, the 10 row height is sized to accommodate the digits from 0 through 9 plus the # and * characters, a 'pause' character, and a 'cancel' character.
  • the authorization code data box 208 is similarly sized ten rows in height but the number of columns in width will be variable depending on the appropriate length of a suitable authorization code.
  • Time constraints data box 212 is provided for the subscriber to indicate to system 10 the time urgency consideration of the facsimile being sent. It is contemplated that a simple scale from 1 to 5 may be used in which the data box would appear as a 5 column single row matrix. The subscriber would mark 5 for extremely urgent or progressively scale their way down to 1 which would indicate to system 10 that the facsimile is not urgent and is available, for example, a two-day delivery time.
  • Time constraints data box 212 is significant in the sense that typically, the fees a subscriber will pay for transmitting their facsimile via system 10 would be scaled in accordance with the desired time urgency. Furthermore, a specification of time constraint permits system 10 to move away from real-time facsimile transmission which would inevitably alleviate critical scheduling considerations during peak operating times. The method of scheduling and co-ordinating traffic over system 10 will be described in greater detail below.
  • the advantage of employing keypage 200 of Figure 3a is that the subscriber simply enters the data required by system 10 by means of shading in boxes corresponding to the correct alpha-numeric data.
  • This method is analogous to bubble card technology developed by IBM however, it provides a means of conveying data to system 10 which is both easily readable by the subscriber and accurately readable by system 10.
  • the bubble card format provides the advantage mat the user may quickly and easily fill out the required information on the key page without any special knowledge of data formats as previously required by several prior-art methods such as bar-coding techniques.
  • dialing digits data box 204 is designed to resemble a conventional numeric dialing pad of a telephone. This could be included as an optional feature to appeal to customers who are not comfortable with the use of conventional bubble type data entry.
  • the subscriber simple strokes a marking instrument through the white rectangle proximal the desired digit. If the subscriber makes an entry error, the subscriber simply strokes the marking instrument through the entire column as indicated in the figure.
  • the key page could be put into a digital document form which may be filled out on a conventional word processor program or incorporated into facsimile software in a similar manner to that of conventional predefined cover page libraries and/or address databases.
  • the popular Delrina WinfaxTM software program could include an addition whereby, upon selecting the recipient of the facsimile from the integrated phone book feature, the software would then automatically generate the appropriate key page which would be placed ahead of the cover page in the facsimile.
  • the standard subscriber data as that previously described with respect to items 204 through 220, would be transposed onto the key page automatically prior to each transmission, from data input once from either a set-up window or on configuration options similar to those already employed with respect to set up of station ID.
  • keypage 200 when employing a software package such as facsimile software, a physical representation of keypage 200 is not required to be generated.
  • a dialog box would be employed to permit the subscriber to enter the keypage data which is either converted automatically to a DTMF signal or is transmitted ahead of the facsimile as a T.29 binary object in a data packet.
  • keypage 200 is preferred as a means of signaling system 10 as to an incoming facsimile transmission, there are several alternative signaling means which may be employed with equal success.
  • touch-tone signaling may be employed using the conventional Dual Tone Multi-Frequency (DTMF) and T.30/T.130 standard.
  • DTMF Dual Tone Multi-Frequency
  • T.30/T.130 T.30/T.130
  • DID Direct Inward Dialing
  • the subscriber group is assigned a block of dial-in numbers which are in turn, assigned to individual members in the group. Therefore, each member in the subscriber group has their own unique number with which they dial FPOP 14.
  • DID Direct Inward Dialing
  • a second level of security is provided against unauthorized use of the system. For example, if an unauthorized person obtains keypage 200 which has been previously completed to include the authorization code by a subscriber, it is possible use the subscriber's authorization code and duplicate keypage 200.
  • signaling means could include: handwritten signaling wherein a subscriber handwrites the data and POP 14 is provided with software for identifying and converting handwritten text to digital data; typed keypage signaling wherein a subscriber types via a typewriter or word processing the data required on keypage 200, then POP 14 employs OCR or optical character recognition to convert the keypage data into digital data; and verbal signaling wherein a subscriber tells POP 14 the required information and wherein voice recognition software is employed to convert to digital format.
  • More sophisticated signaling means could include digital media wherein a subscriber completes a keypage on-line via a personal type computer upon establishing a modem connection with POP 14.
  • an interactive signaling means could be employed such as the completion of an internet web page or an e-mail form which is then transmitted to POP 14 upon completion of the keypage. Facsimile pages could then be transmitted as an attachment to the keypage in digital format.
  • each POP 14 is responsible for receiving the facsimile sent by the subscriber using SFM 28 and transmitting the facsimile to DFM 34. As shown in Figure 2, the function of each POP 14 is not limited to the tasks of receiving and transmitting facsimiles.
  • FIG. 4 The process of sending long distance facsimile in accordance with the presently described embodiment of the present invention is illustrated in Figures 4 and 5.
  • the process for sending long distance facsimile with respect to the subscribers are indicated generally at 300.
  • This process assumes, however, that the user has subscribed to the service and has entered into a contract arrangement with the providers of system* 10. It is contemplated that in subscribing to a system 10, the subscriber has a plurality of options available to them including selecting their appropriate custom billing and customize keypage options which will depend on the nature of the organization. The details of these options will be described in greater detail below.
  • the functional responsibility of RADB 22 and BFDB 24 in relation to dataflow through system 10 is illustrated in Figure 4.
  • RADB 22 generally governs routing of all facsimile transmissions between FPOP 14 and/or DPOP 14.
  • any one of the plurality of POPs 14 functions as a FPOP two-way routing and authorization communication is established between RADB 22 as indicated by the double-headed arrow between FPOP 14 and the routing function.
  • the routing function of RADB 22 is optimized for speed and as shown in the figure, the routing between an FPOP, IPOP and DPOP is determined by this routing function.
  • the routing function of RADB 22 receives routing policy instructions from BFDB 24.
  • the routing policy function of a BFDB 24 is optimized for analysis and is governed by a set of rules based on available resources, available routing, time of day and cost considerations.
  • RADB 22 is governed by the routing policies BFDB 24.
  • the routing function of RADB 22 is adjusted accordingly.
  • RADB 22 further forwards database records generated for each facsimile transmission based on the subscriber identification and authorization and call details to a call details records component of BFDB 24. These records are, in turn, in communication with a billing/service policy object.
  • the billing/service policy object of BFDB 24 is a policy object which identifies a basic rule structure to govern billing procedures and/or custom billing options if requested by the subscriber, subscriber authorization codes and customized subscriber security features.
  • a feedback mechanism is also included as a service component of BFDB 24 and provides feedback to the service policy component.
  • the routing policy object would be governed by an expert system
  • the billing/service policy object could, in fact, be a manual method but is nonetheless provided as an interface for adjusting the service policy of system 10 for enhanced performance.
  • the process of transmitting a long distance facsimile from a subscriber to a destination by means of employing system 10 is described with respect to Figure 5 and indicated generally at 300.
  • the first step in transmitting a facsimile via system 10 is for the subscriber to prepare keypage 200 by completing the required data fields as previously described (block 304).
  • the subscriber then places keypage 200 as a first page of the facsimile and inserts the document into SFM 28 (block 308).
  • the subscriber dials system 10 via an assigned FPOP 14.
  • the assignment of FPOP 14 to a particular subscriber is dependent on a number of factors. These factors include geographical relationship and/or telephone long distance cost considerations as previously described. Furthermore, in some instances, when the subscriber wishes to use system 10 but is not in a location proximal to the assigned FPOP
  • FPOP 14 answers the incoming subscriber call and receives the facsimile into the system.
  • the facsimile is received into FPOP 14, it is converted from the conventional analog facsimile protocol employed into a digital data stream.
  • FPOP 14 identifies keypage 200 as the first page of the facsimile by identifying registration means 202 (block 317). If a keypage is not identified, FPOP 14 terminates the transmission and/or sends an error report back to subscriber SFM 26 if the subscriber facsimile number can be determined from the telephonic connection (block 318).
  • FPOP 14 separates keypage 200 from the facsimile.
  • an identification means is used to identify the separated keypage 200 with the corresponding facsimile.
  • FPOP 14 assembles data from keypage 200 into a keypage packet. The contents of the keypage packet and relationship to system 10 will be described in greater detail below.
  • the FPOP 14 then moves the package to a queue in preparation for transmission to RADB 22. At a predetermined interval, the keypage packets are then transmitted to RADB 22 for authorization (block 332).
  • RADB 22 then receives the keypage packet. If the authorization is accepted (block 340) RADB 22 proceeds to prepare the routing for the facsimile (block 344). At a predetermined time interval, the routing information is transmitted with the authorization back to FPOP 14 (348). If, at block 340, authorization is rejected, the process moves to block 352 where a no authorization message is transmitted back to FPOP 14. The bitmap image of keypage 200 is then stored to memory at block 356 and a copy of the image is sent to a queue for transmission to RADB 22 (block 357) . On a predetermined time interval, the bitmap images in the queue are transmitted to RADB 22 and then to BFDB 24 for archival and auditing purposes (blocks 359 and 359a).
  • FPOP 14 sends a status message confirming or rejecting the subscriber transmission (block 360) via a facsimile to DFM 34 (previously SFM 28).
  • FPOP 14 then compresses, encrypts and stores the facsimiles (blocks 364, 368, 372) in preparation for transmission to DFM 34.
  • the compresed and encrypted facsimile is entered into the transmission queue at a scheduled time (block 374) .
  • the facsimile is then packetized at block 378 and then transmitted via the routing determined from RADB 22 via VPN 18 (block 382).
  • the communication mode employed by VPN 18 is determined by the routing optimization performed by RADB 22 at block 344. These instructions are attached in the packetized facsimile transmission for routing purposes.
  • the packetized facsimile transmission is now received at either IPOP 14 or DPOP 14. If the transmitted facsimile has arrived at DPOP 14 (block 390), the facsimile waits for clearance to transmit to DFM 34 (block 392). Once clearance is received, the facsimile is then decrypted (block 394), decompressed (block 398) and finally transmitted from DPOP 14 to DFM 34 (block 402).
  • DPOP 14 then confirms completion of the facsimile transmission to BFDB 24 (block 404) and also notifies FPOP 14 at block 408. FPOP 14 then sends confirmation of the success or failure of the facsimile transmission to the subscriber via DFM 34 (previously SFM 28) (block 412). At this point, the facsimile transmission is complete and the process ends at block 416.
  • the decision at block 390 causes the facsimile transmission to continue on the routing determined by RADB 22 (block 420) via VPN 18 and the process moves back to block 386 until DPOP 14 is encountered.
  • FPOP 14 keypage 200 is retained and stored to fixed storage as a bitmap image.
  • the purpose for converting the keypage into a bitmap image is two-fold. Firstly, the bitmap image of the keypage can be used for auditing purposes for verification against what the subscriber has sent through system 10. Secondly, the bitmap images can be used for internal diagnostics to check to determine whether FPOP 14 is forwarding or delivering the facsimiles as per the instructions of RADB 22.
  • the events occurring at block 328 and 357 are situations in which the packeted data is queued prior to being transmitted to RADB 22.
  • the primary reason for queuing is due to the fact that when considering the deployment on a worldwide scale, several hundred thousand transactions may be occurring at any one time.
  • the system 10 is constructed with a centralized architecmre, only one RADB 22 unit and one BFDB 24 unit services the plurality of POPs 14.
  • the present inventors have determined that a preferred method of communication involves the polling technique. Therefore, RADB 22 polls each of the plurality of POPs 14 at predetermined time intervals. When a particular POP 14 is polled, the connection time between POP 14 and RADB 22 occurs for a discrete time interval.
  • RADB 22 sends out a heartbeat to a specific POP address
  • FPOP 14 responds with a send request.
  • FPOP 14 transmits the keypage packets queued at block 328 in Figure a.
  • RADB 22 then processes these keypages to determine authorization and routing as per blocks 336 through 352.
  • FPOP 14 would have to wait until a subsequent heartbeat to receive the authorizations and routings.
  • FPOP 14 may further transmit keypage 200 bitmap images queued at block 358 of Figure a. This time interval may also be used for transmission of diagnostic data for determining system integrity.
  • each mode will be determined by the size of the network, as determined mainly by the number of FPOPs 14 in communication with RADB 22 or the volume of data traffic transmitted across system 10.
  • the first mode of communication is a real-time mode in which
  • FPOP 14 uses an interrupt signal to RADB 22.
  • RADB 22 upon the interrupt signal, RADB 22 responds by opening a communication line at the request of the FPOP. While this situation is useful for smaller networks, each of the plurality of FPOPs 14 controls the communication to RADB 22.
  • the second data transmission mode is one in which authorization and routing occur upon the heartbeat sent out by RADB 22.
  • This mode implies that FPOP 14 sends the keypage packets and receives authorization and routing instructions prior to the discrete time interval timing out. This is a preferable mode of operation as each plurality of FPOPs 14 are not required to wait over successful heartbeats.
  • a third mode of communication upon a first beat, keypage packets are transmitted to RADB 22 and authorization is returned, however, there might not be enough time to complete the routing instructions before the discrete time interval times out. Therefore, the completion of the routing instructions will be returned upon a second beat communication with the FPOP.
  • the fourth mode of communication is one in which authorization is transmitted from RADB 22 to FPOP 14 upon a first beat from RADB 22 and routing instructions are returned upon a second beat.
  • a fifth mode of communication is one in which the keypage packets are transmitted to FPOP 14 from RADB 22 with diagnostics and optional bitmap image transmissions and authorization routing is returned upon a second beat initiated by RADB 22. It is contemplated that this mode of communication would be useful for a significant percentage of the time due to the processing requirement placed upon RADB 22 when communicating with a large network of POPs 14.
  • the sixth mode of communication is one in which POP 14 will have to wait for a third or subsequent heartbeat from RADB 22 before authorization be returned.
  • POP 14 upon separation of keypage 200 from the facsimile at block 320, POP 14 assemblies a keypage packet.
  • the keypage packet only includes the required data extracted and interpreted from the data boxes contained on keypage 200.
  • the packet size can be reduced to alleviate the extra data required to reproduce keypage 200 in its complete form.
  • keypage 200 is converted to a bitmap image in its entirely at block 356 for auditing purposes. These bitmap images can be transmitted out of real ⁇ time at the convenience of a RADB 22 and FPOP 14 depending on the volume of data traffic, thereby reducing or alleviating processing demands on a RADB 22 during peak traffic periods.
  • the keypage packet will include the following data items: POP identification; time stamp; a send request; time priority; user identification; document identification; destination identification; and a content description. More or less data items may be included depending on the nature of the facsimile transmission. However, it is preferred that all the data required for RADB 22 to process a given authorization and routing be included in one packet for processing processes. It is also preferred that the keypage packet be transmitted at the highest priority level between FPOP 14 and RADB 22 relative to diagnostic data transmission and bitmap image transmissions.
  • RADB 22 returns authorization for a particular facsimile transmission with data representing one of four possible states. Specifically, a clear signal indicates that POP 14 is permitted to transmit the identified facsimile along the forthcoming routing path. A not clear signal indicates that a particular facsimile transmission is not authorized for routing, thereby instructing that FPOP 14 to hold the facsimile. A third unknown state can occur when RADB 22 had not sufficient time to complete the authorization request, thereby instructing POP 14 to wait for further instructions. Finally, the fourth authorization state occurs when RADB 22 returns the data instruction indicating FPOP 14 to use discretion in transmitting the identified facsimile. In this situation, POP 14 is required to make its own decision as to authorizing the routing and transmission of the facsimile. This situation can occur when operating in a default mode where routing is determined by employing a destination DPOP 14 routing lookup table.
  • the facsimile is finally transmitted from DPOP 14 to DFM 34 at block 402.
  • DFM 34 several events can occur when attempting a facsimile transmission to DFM 34.
  • DPOP 14 If DPOP 14 is successful in its transmission to DFM 34, the facsimile file transmitted is deleted from the memory of DPOP 14. If a problem in the transmission occurs, DPOP 14 can attempt a fixed number of retry s thereby successively attempting a successful transmission. However, there may be situations in which no fax signal is detected, DPOP 14 encounters multiple rings, or a non- fax line is detected. Under these events, a retry attempt can be made thereby attempting successful transmission.
  • each DPOP 14 would be programmed with a basic instruction set which is customized to the local governing rules and regulations regarding telecommunications.
