Abstract

The invention describes a system and method of providing a telecommunication, typically using Signaling System 7 (SS7) protocol, in which data is transferred over a standard communication link (i.e., hardwire, optical fiber) between a first and a second telecommunication device in a telecommunication network, and a communication link is established over a satellite, such as a Low Earth Orbiting (LEO) satellite, in order to transfer the data between the first and second telecommunication devices when the data transfer over the standard communication link is impaired. Signals are generally converted from a first format to a second format that is suitable for satellite transmission. The first device is typically a Service Switching Point (SSP) and the second device is typically a Signal Transfer Point (STP). The communication link over a satellite is automatically established in response to detecting a failure in the standard communication link.

Claims

1. A method of providing a telecommunication link, comprising:

transferring data over a standard communication link between a first and a second telecommunication device in a telecommunication network; and

establishing a communication link over a satellite to transfer the data between the first and second telecommunication devices when the data transfer over the standard communication link is impaired.

2. The method of claim 1, wherein establishing the communication link over a satellite further comprises establishing a communication link over a Low Earth Orbiting (LEO) satellite.

3. The method of claim 1, wherein transferring data over the standard telecommunication link further comprises utilizing a Signaling System 7 protocol.

4. The method of claim 1, wherein the first device is a Service Switching Point (SSP) and the second device is a Signal Transfer Point (STP).

5. The method of claim 1, wherein transferring data over the standard communication link further comprises transferring data over one of (i) a hardwire, and (ii) an optical link.

6. The method of claim 1, wherein establishing the communication link over a satellite further comprises:

detecting an impairment of in the standard communication link; and

automatically establishing the communication link over a satellite in response to detecting the impairment of the standard communication link.

7. The method of claim 1, wherein establishing the communication link over a satellite further comprises converting signals provided by the first telecommunication device in a first format to signals in a second format for transmission to the satellite.

8. The method of claim 1, wherein establishing the communication link over a satellite further comprises splitting the data over multiple channels.

9. A telecommunication system, comprising:

a standard communication link for transferring data between a first and a second telecommunication device in a telecommunication network; and

a communication link over a satellite established for transferring the data between the first and second telecommunication devices when the data transfer over the standard communication link is impaired.

10. The system of claim 9, wherein the communication link over a satellite further comprises a communication link over a LEO satellite.

11. The system of claim 9, further comprising transferring data between the first and second devices over the standard communication link utilizing a Signaling System 7 protocol.

12. The system of claim 9, wherein the first device is a Service Switching Point (SSP) and the second device is a Signal Transfer Point (STP).

13. The system of claim 9, wherein the standard link further comprises one of (i) a hardwire, and (ii) an optical link.

14. The system of claim 9, wherein establishing the communication link over a satellite further comprises:

detecting an impairment of the standard communication link; and

establishing the communication link over a satellite in response to detecting the impairment of the standard communication link.

15. The system of claim 9, wherein establishing the communication link over a satellite further comprises converting signals provided by the first telecommunication device in a first format to signals in a second format for transmission over the satellite.

16. The system of claim 9, wherein establishing the communication link over a satellite further comprises splitting the data over multiple channels.

17. An apparatus for establishing a telecommunication link, comprising

a first device that receives data relating to a telecommunication service and converts the received data into a first format for transmission over a physical communication link;

a second device coupled to the first device, via the physical telecommunication link and a satellite; and

a third device that converts the data from the first format to a second format and transmits the data in the second format to the satellite for further transmission to the second device when the standard communication link is impaired.

18. The apparatus of claim 17 wherein the first device is an SSP device and the second device is an STP device and the first format is in an SS7 protocol.

19. The apparatus of claim 17 wherein the third device automatically transmits data to the satellite upon detection of an impairment of the physical telecommunication link and discontinues data transmission to the satellite when the physical link is no longer impaired.

20. The apparatus of claim 17 wherein the third device splits the data from the first device over multiple channels for transmission to a lower earth orbit satellite.
