Abstract

In this invention, a processor connected to a communication switching system i) intercepts or receives each facsimile message destined for a receiving party, ii) analyzes at least a portion of each message to collect, in addition to the called number, other routing information from the transmitted message, iii) converts the message to a different format, if necessary and iv) delivers that message to at least one of a plurality of other destination facsimile terminals based on a) the routing information gathered from the message and b) pre-arranged routing information stored in the processor and provided by the receiving party.

Claims

1. A method of routing a facsimile message through a communication switching complex, wherein said method comprises the steps of:

receiving said facsimile message in a processor included in said communication switching complex;

accessing a database to retrieve a profile indicating the location and type of information to be recognized in said message;

recognizing in said message information which is similar to said information indicated in said profile;

deriving for said message at least one destination address through at least one table lookup operation using said profile; and

routing said message to said at least one destination address.

2. The method of claim 1, wherein said message is received as a result of a sender dialing a particular number associated with said processor and wherein said database accessing step includes the step of executing programs which use as input a) source information associated with said facsimile message, and b) said dialed number.

3. The method of claim, 1 wherein said routing step further includes the step of converting the format of said received facsimile message.

4. The method of claim 3, wherein said converting step includes the step of translating said facsimile message from text to speech.

5. The method of claim 3, wherein said converting step includes the step of translating said facsimile message from one language to another language.

6. The method of claim 1 wherein said recognizing step includes the step of matching at least one template of a bit-mapped image in said profile to a bit-mapped image in said message.

7. The method of claim 1 wherein said recognizing step further includes the step of matching at least one string of characters in said profile to at least one string of characters in said message.

8. In a communication switching complex which includes a plurality of switches, and at least one processor which is connected to one of said switches and which stores a plurality of subscriber'"'"'s profiles, each of said subscriber'"'"'s profiles including information a) correlating destination address data to bit-mapped images and keywords, and b) indicating the location and type of information to be recognized in a facsimile message received for one of said subscribers, a method of processing and routing a facsimile message comprising the steps of:

retrieving in said processor a particular profile associated with a particular one of said subscribers based on a number dialed by a sender;

comparing at least a portion of said content of said facsimile message to a part of said information in said particular profile to derive from said profile destination information for at least one destination device; and

routing said facsimile message to said at least one destination device.

9. The method of claim 8, wherein said method further includes the step of

routing said facsimile message to at least one default destination when no match is found between said part of said information in said particular profile and said content of said facsimile message.

10. A method of i) processing a facsimile call based on the content of the facsimile message associated with said call and ii) delivering said facsimile message from a sender to at least one of a plurality of destination facsimile terminals connected to a communication switching system, said system including a) a plurality of switches and b) a processor which is linked to one of said switches and which stores i) a database containing subscriber-defined processing instructions, ii) routing tables, and iii) search records containing search keys and position data identifying specific recognizable patterns to be located in defined areas in said message, wherein said method comprises the steps of:

(a) querying said database using said dialed number as a key, to retrieve said processing instructions and said search record from said database;

(b) executing said processing instructions to examine at least a portion of the content of said message to locate said recognizable patterns in said message;

(c) responsive to said locating of said recognizable patterns in said message, translating the identity of said search record to the telephone number(s) of at least one of associated destination facsimile terminals using said routing table for said translating; and

(d) transmitting said message to at least one of said destination facsimile terminals.

11. The method of claim 10, wherein said method further includes the steps of:

ascertaining the busy-idle state of a destination facsimile terminal; and

storing said message for later delivery to said destination facsimile terminal in response to a busy line condition at one of said destination facsimile terminals.

12. The method of claim 11, wherein said method includes the step of delivering said received message to a default destination facsimile terminal in response to said busy line condition.

13. The method of claim 10, wherein said executing step further includes the steps of:

preprocessing said message by aligning said message to correct rotational error and shear distortion;

scanning said preprocessed message to extract said portion of said message identified by said position data in said search record; and

comparing information in said portion of said message to said patterns in said search key of said search record.

14. A system of routing through a communication switching complex a facsimile message transmitted by a sender, said system comprising:

a processor and an associated database;

means for receiving said facsimile message in said processor;

means for retrieving from said database a stored profile indicating the type and location of information to be recognized in said facsimile message;

means for recognizing said information in said facsimile message content;

means for deriving from said profile destination information associated with said information recognized in said facsimile message; and

means for routing said message to at least one destination device indicated by said destination information.

15. The system of claim 14, wherein said means for retrieving said stored profile from said database includes means for executing programs which use as input a) source information associated with said facsimile message and b) a number dialed by said sender to transmit said facsimile message.

16. The system of claim 14, wherein said routing means includes means for converting the format of said facsimile message.

17. The system of claim 16, wherein said converting means includes means for translating said facsimile message from text to speech.

18. The system of claim 16, wherein said converting means further includes means for translating said facsimile message from one language to another language.

19. A system for processing and routing facsimile messages transmitted to a subscriber by a sender'"'"'s originating facsimile terminal connected to a communication switching complex, said system comprising:

a plurality of interconnected switches forming said communications switching complex;

means for retrieving in said processor a particular profile associated with said subscriber based on the number dialed by said sender;

means for comparing at least a portion of the content of said facsimile message located and identified by said information in said profile to identify particular destination address data for said facsimile message and

means for routing said facsimile message to at least one facsimile device identified by said destination information based upon the output of said comparing means.
