Abstract

A system for facilitating interoperability between a plurality of disjoint radio systems across a digital network includes one or more local gateways communicating with a network operations center. Each of the local gateways is associated with at least one radio system, and includes an interface to the digital network, a transceiver receiving wireless communications on the associated radio system, and a router configured to route at least some of the data received from the transceiver on the digital network. The network operations center processes data received from the various local gateways and forwards the processed data to the local gateways associated with the appropriate recipients. Local gateways may also be configured to convert legacy communications to digital formats, and/or may provide digital access to multiple disjoint wireless systems. The network operations center may further provide access security, network management, key management and/or other features.

Claims

1. A method for processing a wireless communication sent between a sending radio system and a disjoint receiving radio system at a network operations center, wherein the network operations center communicates via a digital network with a plurality of local gateways associated with the sending and receiving radio systems, the method comprising the steps of:

receiving a digital message via the network from one of the plurality of local gateways associated with the sending radio system, the digital message representing the wireless communication on the sending radio system; and

processing the digital message at the network operations center to identify an appropriate recipient for the digital message; and

routing the processed digital message over the digital network to one of the plurality of local gateways associated with the appropriate recipient for transmission to the appropriate recipient on the receiving radio system.

2. The method of claim 1 further comprising the step of verifying the security of the digital message.

3. The method of claim 2 wherein the verifying step further comprises verifying a digital signature contained in the digital message.

4. The method of claim 1 further comprising the step of identifying a path to the appropriate recipient.

5. The method of claim 4 wherein the identifying step comprises identifying the path based at least in part upon a quality-of-service associated with the digital message.

6. The method of claim 4 wherein the identifying step comprises identifying a secure pathway to the one of the plurality of local gateways associated with the appropriate recipient and the routing step comprises routing the digital message along the secure pathway.

7. The method of claim 4 wherein the identifying step comprises identifying the path based at least in part upon load balancing considerations.

8. The method of claim 1 further comprising the step of forwarding the digital message to an overseeing authority at the network operations center.

9. A gateway associated with at least one of a plurality of disparate wireless communications systems communicating via a digital network, the gateway comprising:

an interface to the digital network;

a transceiver configured to transmit and receive wireless communications on the associated at least one of the plurality of disparate wireless communications systems; and

a router configured to receive data from the transceiver representing wireless communications on the at least one of the plurality of disparate wireless communications systems and to route at least some of the data on the digital network via the interface to thereby provide interoperability between the plurality of disparate wireless communications systems.

10. The gateway of claim 9 wherein the system further comprises a conversion module coupling the transceiver and the router, wherein the conversion module is configured to convert the wireless communications to the data in a format that is compatible with the digital network.

11. The gateway of claim 10 wherein the conversion module is further configured to convert the data from the format that is compatible with the digital network to a wireless format compatible with the wireless communications.

12. The gateway of claim 9 wherein the interface to the digital network is a satellite interface.

13. The gateway of claim 9 wherein the interface to the digital network is a very small aperture terminal (VSAT) satellite interface.

14. The gateway of claim 9 wherein the interface to the digital network comprises a plurality of redundant interfaces to the digital network.

15. The gateway of claim 9 wherein the transceiver is a digital radio transceiver.

16. The gateway of claim 9 further comprising a second transceiver coupled to the router and configured to transmit and receive wireless communications on a second associated one of the plurality of disparate wireless communications systems.

17. The gateway of claim 9 wherein the router is further configured to route the at least some of the data according to quality-of-service parameters associated with the at least some of the data.

18. The gateway of claim 9 wherein the router is further configured to route the at least some of the data to a network operations center that manages communications with each of the plurality of disparate communications networks.

19. A system for facilitating interoperability between a plurality of disjoint radio systems across a digital network, the system comprising:

a plurality of local gateways, each associated with at least one of the plurality of disjoint radio systems and having an interface to the digital network, a transceiver configured to receive wireless communications on the associated at least one of the plurality of disjoint radio systems, and a router configured to receive data representing the wireless communications from the transceiver and to route at least some of the data on the digital network via the interface; and

a network operations center having an interface to the digital network, wherein the network operations center is configured to process the data received from the digital network to identify an appropriate recipient of the data and to route the processed data over the digital network to a receiving one of the plurality of local gateways associated with the appropriate recipient for transmission on the radio system associated with the receiving local gateway.

20. The system of claim 19 further comprising a regional point-of-presence configured to interlink each of the plurality of local gateways with the network operation center via a plurality of redundant data links.
