Abstract

A method and apparatus is disclosed for delivering messages that utilizes a message queue and a router/filter within a private data network. The private network is connected to an external data network such as the Internet, and has separate outbound resource servers to provide a high degree of scalability for handling a variety of message types.

Claims

1. A system for supporting a message delivery service, comprising:

a server coupled to communicate with a plurality of first outbound resources and a database server, over an internal packet-switched data network, the database server containing account information on customers of the message delivery service, the server implements a router-filter and a message queue,

the message queue to store a request message received from a customer of the message delivery service over an external packet-switched data network,

the router-filter to obtain a request message from the queue, validate said request message by accessing the account information in the database server, and determine to which of the plurality of first outbound resources to assign said request message,

each of the first resources being capable of converting an input request message into a format capable of being received by a fax machine over a circuit switched network.

2. The system of claim 1 wherein the internal data network is a private data network.

3. The system of claim 2 wherein the external data network is the Internet.

4. The system of claim 3 wherein the request message is received from the customer via one of a mail transport protocol server and a hypertext transport protocol server on the Internet.

5. The system of claim 1 wherein the router-filter is to prioritize a plurality of request messages that have been obtained from the queue and that are assigned to an outbound resource.

6. The system of claim 1 wherein the router-filter is to determine which of the plurality of first outbound resources to assign said request message to, based on which resource offers the least cost of delivering said request message.

7. The system of claim 1 wherein the router-filter is to generate an error message that indicates an error in delivering said request message as reported by the outbound resource to which said request message was assigned.

8. The system of claim 1 further comprising:

a plurality of second outbound resources each being capable of converting an input request message into a format capable of being played back to a telephone over a circuit switched network, wherein the router-filter is to determine to which of the first and second resources said request message is to be assigned, based on a message type of said request matching a capability of one of a first resource and a second resource.

9. The system of claim 1 further comprising:

a plurality of second outbound resources each being capable of converting an input request message into a format capable of being transmitted to a paging terminal over one of (1) a circuit switched network and (2) a paging gateway over an external packet-switched network, wherein the route-filter is to determine to which of the first and second resources said request message is to be assigned, based on a message type of said request matching a capability of one of a first resource and second resource.

10. The system of claim 1 wherein a location of each outbound resource is given by an Internet Protocol address.

11. The system of claim 1 wherein the message is received from the customer via one of a mail transport protocol server and a hypertext transport protocol server on the Internet.

12. The system of claim 1 wherein a protocol used by the router-filter to communicate with the plurality of outbound resources is one of HTTP and SHTTP.

13. The system of claim 1 wherein the router-filter is to send a MIME message.

14. An article of manufacture for supporting a message delivery system, comprising:

a machine accessible medium containing data that, when accessed by a machine, cause a server to communicate with an outbound resource and a database all as part of an internal packet-switched data network, the server to store a request message received from a customer of the message delivery service over an external packet switched data network, verify that the request message is from the customer using information in the database, and assign said request message to the resource which converts data associated with said request message into a format capable of being received by a fax machine over a circuit switched network.

15. The article of manufacture of claim 14 wherein the medium includes further data which allows the request message to be received from a customer over the Internet.

16. The article of manufacture of claim 14 wherein the medium includes further data which, when executed by the machine, cause the server to determine which of a plurality of first outbound resources to assign said request message to, based on which resource offers the least cost of delivering said request message.

17. A method comprising:

receiving an email message from an external packet data network;

performing a database lookup in an internal packet data network to correlate the email message with a user account;

verifying within the internal network the email message is associated with a valid user account;

performing within the internal network one of a least cost routing calculation, a billing calculation, a prioritization calculation, and a message filtering operation;

converting within the internal network the email message into a fax format for transmission to a machine; and

transmitting the converted email message into a public switched telephone network to a destination telephone number.

18. A method comprising:

receiving an email message from the Internet;

performing within an internal packet data network a database lookup to correlate the email message with a user account;

determining within the internal packet data network if the email message passes a filter screening criterion;

converting the email message into a fax format for transmission to a fax machine; and

transmitting the converted email message into a public switched telephone network to a destination telephone number.

19. A method comprising:

receiving an email message from the Internet;

performing a database lookup within an internal packet data network to correlate the email message with a user account;

queuing the email message within the internal packet data network;

reading the queued message based on a prioritized ordering rule within the internal packet data network;

converting the read message into a fax format for transmission; and

transmitting the converted message into a public switched telephone network to a destination telephone number associated with the user account.

20. A method comprising:

receiving in an internal packet data network an email message from the Internet;

correlating the email message with a user account in the internal packet data network;

queuing email the message in the internal packet data network;

performing a routing operation to determine a destination to forward the email message;

converting the routed message into a fax format; and

transmitting the converted message into a public switched telephone network to a destination telephone number associated with the user account and determined in said routing.
