Abstract

A system and methods for providing services through an integrated digital network. The present invention embodies a system and methods for providing telecommunications services through an integrated digital network that provides the superset of all previous network types, and can continue to support being the core for existing networks—now used simply as edge access methods. The method includes connecting a multi-service core to existing telecommunications networks, wherein the core can communicate with conventional network components; interconnecting a gateway between the multi-service core and multiple existing network components, wherein the gateway is configured to share multiple service aspects with each network component and to utilize multiple transport protocols to communicate with different core network components; coordinating communications between the gateway and existing network components; and resolving differences between protocols or communications between existing core network components.

Claims

1. A method for converging multiple telecommunications networks, each including network components, into an integrated digital network such that the integrated digital network can provide common network service applications to multiple users, comprising:

connecting a multi-service core to telecommunications networks, wherein the core can communicate with network components;

interconnecting a gateway between the multi-service core and multiple network components, wherein the gateway is configured to share multiple service aspects with each network component and to utilize multiple transport protocols to communicate with different network components;

coordinating communications between the gateway and network components; and

resolving differences between protocols or communications between network components.

2. The method of claim 1, wherein the service aspects consist of at least one of the following:

quality of service (QoS) or security.

3. The method of claim 1, wherein the gateway is a MPLS label edge router.

4. The method of claim 1, wherein the gateway can coordinate the delivery of communications that provides a management and billing function for applying network resources throughout the integrated digital network.

5. The method of claim 1, wherein the gateway is a Voice over Packet gateway.

6. The method of claim 1, wherein the core comprises a series of MPLS switches and routers.

13. The method of claim 1 wherein the common network service applications include voice.

14. The method of claim 1 wherein the common network service applications include data.

15. The method of claim 1 wherein the common network service applications include video.

7. A system for providing network services to multiple network users through an integrated digital network comprising multiple telecommunications networks, each including network components, comprising:

a multi-service core with shared service aspects of an associated gateway;

at least one service gateway interconnected to core network components such that one or more telecommunications networks can exchange communications, wherein the gateway is configured to

provide shared service aspects with each telecommunication network;

utilize multiple transport protocols to communicate with network components of different telecommunications networks;

coordinate communications between network components of different telecommunications networks; and

resolve differences between protocols or communications between network components of different telecommunications networks.

8. The system of claim 7, wherein the service aspects consist of at least one of the following:

quality of service (QoS) or security.

9. The system of claim 7, wherein the gateway is a MPLS label edge router.

10. The system of claim 7, wherein the gateway can coordinate the delivery of communications that provides a management and billing function for applying network resources throughout the integrated digital network.

11. The system of claim 7, wherein the gateway is a Voice over Packet gateway.

12. The system of claim 7, wherein the core comprises a series of MPLS switches and routers.

16. The system of claim 7 wherein the network services include voice.

17. The system of claim 7 wherein the network services include data.

18. The system of claim 7 wherein the network services include video.
