Abstract

Methods and systems are disclosed for transferring service application data from a server to a subscriber device via the PSTN without establishing a call between the server and subscriber device and without the PSTN switching components having inherent knowledge as to the data content. The server defines a generic request message, which contains the service application data and data delivery instructions. This generic request message is delivered to the subscriber'"'"'s terminating switch, which subsequently delivers the service application data to the subscriber based on the data delivery instructions. The terminating switch then defines a generic response message and delivers it to the server, informing the server as to status of the data delivery. Similarly, methods and systems are also taught for broadcasting data from a server to a plurality of devices via the PSTN.

11. The method of claim 1 wherein the step of transporting the data to the subscriber device further includes the step of over-riding vertical services defined for the terminating node-subscriber device interface based on the data delivery instructions.

12. A method for delivering data from a central server to a subscriber device by means of a PSTN based node, wherein the central server interfaces the PSTN, and wherein the node does not examine and has no embedded knowledge of the data, said method comprising the steps of:

defining a request message at the central server wherein the request message comprises the data and data delivery instructions instructing the node on how to deliver the data to the subscriber device;

transporting the request message from the central server to the node without establishing a call; and

delivering the data to the subscriber device based on the data delivery instructions.

13. The method of claim 12 further including the steps of:

recording in a response message the status of the delivery of the data to the subscriber; and

transporting the response message to the central server.

14. The method of claim 12 wherein a user of the subscriber device establishes a voice-band connection as a result of receiving the data.

15. The method of claim 14 wherein the user retrieves information over the voice-band connection.

16. The method of claim 12 wherein the subscriber device automatically establishes a connection as a result of receiving the data and retrieves information over the connection.

17. A method for broadcasting data from a central server to a plurality of subscriber devices by means of a PSTN based node, wherein the central server interfaces the PSTN, and wherein the node does not examine and has no embedded knowledge of the data, said method comprising the steps of:

defining a request message at the central server wherein the request message comprises the data and data delivery instructions, whereby the delivery instructions specify to the node a list of possible subscriber devices served by the node that should receive the data;

routing the request message from the central server to the node without establishing a call; and

delivering the data, based on the delivery instructions, to the list of subscriber devices.

18. The method of claim 17 wherein the list of subscriber devices specified in the request message is specified as a range of addresses.

19. The method of claim 17 wherein the list of subscriber devices specified in the request message is specified as all numbers within a NPA-NXX available on the node.

20. The method of claim 17 wherein transporting the data to each subscriber device occurs regardless of whether the subscriber device is off-hook or on-hook.

21. The method of claim 17 wherein transporting the data to each subscriber device does not require subscriber interaction.

22. The method of claim 17 wherein the plurality of subscriber devices are served by a plurality of nodes, said method further comprising the steps of:

defining a plurality of request messages at the central server, one request message per node, wherein each request message comprises the data and data delivery instructions whereby the delivery instructions specify to the corresponding node a list of possible subscriber devices served by the node that should receive the data;
