Abstract

A method for controlling circuit switched communications using switched virtual circuit (SVC) signaling includes receiving, at a service controller over a signaling channel from an originating end system, a connection setup signal requesting a switched virtual circuit connection. A proxy setup signal enabling setup of the switched virtual circuit connection in response to the connection setup signal is sent over a proxy signaling channel separate from the signaling channel.

Claims

1. A method for controlling circuit switched communications using switched virtual circuit (SVC) signaling, the method comprising:

receiving, at a service controller over a signaling channel from an originating end system, a connection setup signal requesting a switched virtual circuit connection; and

sending, over a proxy signaling channel separate from the signaling channel, a proxy setup signal enabling setup of the switched virtual circuit connection in response to the connection setup signal.

2. The method according to claim 1,

wherein the connection setup signal is routed from the originating end system to the service controller through a switch.

3. The method according to claim 2,

wherein the switch comprises an asynchronous transfer mode switch.

4. The method according to claim 2,

wherein the switch comprises an edge switch.

5. The method according to claim 1,

wherein the switched virtual circuit connection includes a connection through the switch.

6. The method according to claim 1,

wherein the end system comprises an addressable communications device provided with a terminating communications address.

7. The method according to claim 1,

wherein the signaling channel comprises a permanent virtual circuit (PVC) connection.

8. The method according to claim 1,

wherein the signaling channel comprises a dynamically established signaling channel.

9. The method according to claim 1,

wherein the signaling channel comprises a multiplexed virtual channel.

10. The method according to claim 1, further comprising:

determining at least one service feature authorized for the originating end system based on which the proxy setup signal enabling setup of the switched virtual circuit is sent.

11. The method according to claim 1, further comprising:

determining at least one service feature authorized for a terminating end system, based on which the proxy setup signal enabling setup of the switched virtual circuit is sent.

12. A service controller for controlling circuit switched communications using switched virtual circuit (SVC) signaling, the service controller comprising:

a receiver that receives, over a signaling channel from an originating end system, a connection setup signal requesting a switched virtual circuit connection; and

a sender that sends, over a proxy signaling channel separate from the signaling channel, a proxy setup signal enabling setup of the switched virtual circuit connection in response to the connection setup signal.

13. The service controller according to claim 12,

wherein the service controller communicates with a switched virtual circuit server to check features authorized for the originating end system.

14. The service controller according to claim 12,

wherein the service controller communicates with a switched virtual circuit server to check features authorized for a terminating end system.

15. The service controller according to claim 12,

wherein the originating end system comprises an asynchronous transfer mode switched virtual circuit signaling device.

16. The service controller according to claim 12,

wherein the connection setup signal comprises user to network interface (UNI) signaling.

17. The service controller according to claim 12,

wherein the proxy setup signal comprises switched virtual circuit (SVC) connection protocol compliant signaling.

18. The service controller according to claim 12,

wherein the service controller is configured to receive connection setup signals from a plurality of originating end systems.

19. The service controller according to claim 12,

wherein the service controller is configured to send proxy setup signals to a plurality of switches.

20. A computer readable medium that stores a computer program for controlling circuit switched communications using switched virtual circuit (SVC) signaling, the computer readable medium comprising:

a receiving code segment that receives, at a service controller over a signaling channel from an originating end system, a connection setup signal requesting a switched virtual circuit connection; and

a sending code segment that sends, over a proxy signaling channel separate from the signaling channel, a proxy setup signal enabling setup of the switched virtual circuit connection in response to the connection setup signal.
