Abstract

In a method of routing digital signals based on criteria defined by the user all messages receive a prioritization based on the criteria defined by the individual user. Based on this guidance, each digital message is Tagged so that Overlay software can determine the prioritization that will be applied to the message and subsequently which media or route will be used and when a message should be sent. The Overlay software uses embedded look-up tables, which define available routes so that prioritization decisions can be made, real-time, based on route status or cost, and prioritization algorithms or a combination of both to determine the most appropriate media or route to send a message. The Overlay software also counts each message, the route used, and the time sent to enable accounting verification at an appropriate time in the future.

Claims

1. A method for selecting a DSP route for a digital message, the method comprising the steps of:

a) providing a unique prioritization tag for the digital message;

b) supplying prioritized criteria from the user to an overlay software;

c) choosing the DSP route by evaluating the prioritized criteria in the overlay software; and

d) routing the digital message through the chosen DSP route.

2. The method of claim 1 further comprising the step of tracking the chosen DSP route for accounting purposes.

3. The method of claim 2 further comprising the step of preparing a billing record of the chosen DSP route.

4. The method of claim 1 further comprising repeating steps a) through d) for a next user.

5. The method of claim 1 further comprising repeating steps a) through d) for a next digital message.

6. The method of claim 1 wherein said prioritized criteria comprises at least one of the following criteria:

a) cost of sending the digital message;

b) speed of delivery of the digital message;

c) security of the digital message; and

d) integrity of the digital message.

7. The method of claim 1 wherein the step of choosing a DSP route is performed at a member of the group consisting of a vehicle, a user initiation facility, and a government control facility.

8. The method of claim 1 wherein the step of tagging comprises manual tagging.

9. The method of claim 1 wherein the step of tagging comprises automatic tagging.

10. The method of claim 1 wherein said overlay software comprises at least one of the following:

lookup tables;

logarithmic calculations and real-time information on cost;

available DSP routes; and

DSP route status information.

11. The method of claim 10 further comprising the step of updating the real-time information.

12. The method of claim 11 wherein the step of updating comprises time-based updates.

13. The method of claim 11 wherein the step of updating comprises querying at least one DSP provider.

15. The method of claim 14 further comprising the step of tracking the chosen DSP route for accounting purposes.

16. The method of claim 14 further comprising repeating steps a) through e) for a next digital message.

17. The method of claim 14 wherein said prioritized criteria comprises at least one of the following criteria:

a) a cost of sending the digital message;

b) speed of delivery of the digital message;

c) security of the digital message; and

d) integrity of the digital message.

18. The method of claim 14 wherein said overlay software comprises at least one of the following:

lookup tables;

logarithmic calculations and real-time information on cost;

available DSP routes; and

DSP route status information.

14. An avionics routing method for digital messages, the method comprising the steps of:

a) providing a unique prioritization tag for a digital message;

b) supplying prioritized criteria from the user to an overlay software;

c) evaluating the prioritized criteria by the overlay software;

d) choosing a DSP route from at least two DSP service providers by the overlay software; and

e) transmitting the digital message through the chosen DSP route.
