Universal document transport
View Patent ↗A universal document transport facility is described where, in various embodiments, the facility recognizes document requests based on a received document, interacts with document routing rules and workflow requirements with respect to the received document, and manages content flows between network nodes or devices. In various embodiments, the facility includes a document transport module for transporting documents between network devices, such as printers, fax boards, and content servers and across local and wide-area networks; functionality for routing optimization with other communications networks, such as messaging services, telephony, and IP networks; and flexible document transport capabilities to workflow applications and multifunction devices (such as all-in-one print/scan/copy/fax/telephone/answering machine devices) and multifunction devices enhanced with video & video capture, messaging, email, network router & gateway capabilities.
1. A method for handling documents of various types, the method comprising:
receiving a document at a fax server;
associating metadata with the document;
forwarding the document and related metadata to one of multiple document transport modules;
assessing dialing or routing rules based on the metadata for the document;
routing the document by the document transport module via one of multiple communication methods, including without limitation the Public Service Telephone Network (“PSTN” ), another document transport module, Internet, mobile device network, wireless device network, document server, another fax server, or a board server containing one or more communications hardware devices, wherein the routing is based on at least one dialing or routing rule; and
repeating the associating, forwarding, assessing and routing for any subsequent document transport module that receives the document, wherein the dialing or routing rules are applied independently at each document transport module encountered by the document during processing of the document.
2. The method of claim 1 wherein the document is input in text or image format from a scanner bed.
3. The method of claim 1 wherein the document is input in a T.30 image format from a PSTN inbound fax, as an SMS message from a wireless network system, as an email message from the Internet, or as a document task from another document transport module.
4. The method of claim 1 wherein the metadata for the document includes one or more from the set of a user identification, group membership, task priority, document type, transmission rule, or workflow information.
5. The method of claim 4 wherein a document transport module modified the metadata for the document by application of rules or by association of additional status information.
6. The method of claim 1 wherein the routing includes placing the document in a queue that is associated with the document transport module.
7. The method of claim 1 including delivery of the document when the document can be routed without employing a subsequent document transport module.
8. A computer-readable medium whose contents cause at least one data processing platform to process a document under a document processing method, the method comprising:
recognizing at least one document request based on a received document;
interacting with one or more document routing rules and one or more workflow requirements with respect to the received document; and
managing content flows between network nodes or devices, wherein a same document transport module processing architecture is employed for document handling or transporting at each node or device, wherein a common scheduling and a common queue support multiple transport types, and wherein the managing of content flows includes selecting document- or hardware-specific processing tasks by reference to a type of protocol associated with the document or a desired handling of the document, wherein dialing or routing rules are applied independently at each document transport module encountered by the document during processing of the document.
9. The computer-readable medium of claim 8 wherein the computer-readable medium is a memory of a facsimile server.
10. The computer-readable medium of claim 8 wherein the computer-readable medium comprises a memory of a document server or a board server.
11. The computer-readable medium of claim 8 wherein the computer-readable medium comprises a logical node in a computer network receiving the contents, a network service receiving the contents, a network storage system, a database server, a computer-readable disk, or a memory of a computer system.
12. An apparatus for handling various documents, the apparatus comprising:
document transport means for transporting documents between network devices, wherein the network devices include printers, fax boards, multifunction devices, and content servers and across local and wide-area networks; and
means for routing optimization with other communications networks, wherein the network devices include messaging services, telephony, Internet, mobile and wireless networks, IP networks, or other document transport modules wherein each document transport module is configured to apply dialing or routing rules independently the documents encounter during processing.
13. The apparatus of claim 12 wherein the means for routing optimization employs dialing or routing rules to determine whether to forward a document to another document transport means.
14. The apparatus of claim 12 , wherein the document transport means comprises a document conversion means.
15. The apparatus of claim 12 wherein the document conversion means is triggered by a change in a document delivery protocol or a change in a network service receiving the document.
16. The apparatus of claim 12 , wherein the document transport means interacts with rules when a human answers a facsimile transmission.
17. The apparatus of claim 12 , wherein the document transport means comprises:
communication means for performing discrete document creation, storage and transmission tasks between various communication networks and network servers;
means for providing flexible, programmable communication of documents in various message formats and on various network types; and
means for routing the document communications via optimization routing rules.
18. The apparatus of claim 17 wherein the document transport means communicates with another document transport means that is configured for use with a server.
19. The apparatus of claim 17 wherein the document transport means communicates with another document transport means via a secure connection.
20. The apparatus of claim 17 wherein the document transport means communicates with a public switched telephone network.
21. The apparatus of claim 17 wherein the document transport means communicates with another document transport means.
22. The apparatus of claim 17 wherein the document transport means communicates with an Internet, an intranet, or an IP network connection.
23. The apparatus of claim 17 wherein the document transport means communicates with a mobile device network or wireless network connection.
24. The apparatus of claim 17 further comprising a workflow integration module for integrating transported documents into a workflow application.
25. The apparatus of claim 17 wherein the means for routing optimization employs dialing or routing rules to determine whether to forward a document to another document transport means.
26. The apparatus of claim 17 , wherein the document transport means comprises:
a document conversation means associated with a change in a document delivery protocol or a change in the network service receiving the document.
27. The apparatus of claim 17 , wherein the document transport means interacts with rules when a human answers a facsimile transmission.
