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, the method comprising:

connecting a multi-service core to telecommunications networks, wherein the multi-service core is a common integrated digital network that communicates with network components of multiple telecommunications networks outside of the multi-service core;

interconnecting multiple gateways between the multi-service core and multiple network components, each gateway interconnecting one network component with the multi-service core, wherein the multiple gateways share multiple service aspects with the multiple network components by utilizing multiple transport protocols comprising frame relay, asynchronous transfer mode (ATM), Ethernet, Internet Protocol (IP), and Generalized Multiprotocol Label Switching (GMLS);

coordinating communications between the gateway and network components by providing a single high level network control plane for implementing scaling among the multiple network components using at least one of Open Shortest Path First (OSPF) or Border Gateway Protocol (BGP);

resolving differences between protocols or communications between network components; and

providing the service applications to the multiple users by implementing a plurality of respective network-independent quality of service (QoS) parameters each defined in accordance with a corresponding service application of the service applications;

wherein the multiple gateways can coordinate the delivery of communications that provides a management and billing function for applying network resources throughout the integrated digital network.

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 is a Voice over Packet gateway.

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

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

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

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

9. A system for providing network service applications to multiple users through an integrated digital network comprising multiple telecommunications networks including multiple network components, the system comprising:

a multi-service core with shared service aspects of an associated gateway, wherein the multi-service core is a common integrated digital network;

a plurality of service gateways interconnected to said network components, each gateway interconnecting one network component with the multi-service core such that one or more telecommunications networks outside of the multi-service core can exchange communications, wherein the plurality of service gateways;

provide shared service aspects with the multiple network components by utilizing multiple transport protocols comprising frame relay, asynchronous transfer mode (ATM), Ethernet, Internet Protocol (IP), and Generalized Multiprotocol Label Switching (GMLS);

coordinate communications between network components of different telecommunications networks by providing a single high level network control plane for implementing scaling among the multiple network components using at least one of Open Shortest Path First (OSPF) or Border Gateway Protocol (BGP);

resolve differences between protocols or communications between network components of different telecommunications networks such that the multi-service core communicates with network components of multiple telecommunications networks via the gateway; and

provide the service applications to the multiple users by implementing a plurality of respective network-independent quality of service (QoS) parameters each defined in accordance with a corresponding service application of the service applications;

wherein the plurality of service gateways can coordinate the delivery of communications that provides a management and billing function for applying network resources throughout the integrated digital network.

10. The system of claim 9, wherein the service aspects consist of at least one of the following:

quality of service (QoS) or security.

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

12. The system of claim 9, wherein the gateway is a Voice over Packet gateway.

13. The system of claim 9, wherein the core comprises a series of MPLS switches and routers.

14. The system of claim 9 wherein the network services include voice.

15. The system of claim 9 wherein the network services include data.

16. The system of claim 9 wherein the network services include video.
