Abstract

A communication system includes a subsystem that provides an interface between an IP based telephone control network and a public data network, the subsystem is used for registration of a subscriber'"'"'s devices on the public data network with the telephone network and enables receiving and/or originating communication sessions from the devices through the telephone network. The subsystem can emulate a P-CSCF function to couple devices on the public Internet, for example voice-over-IP devices, to an IMS or MMD cellular telephone infrastructure.

Claims

1. A communication system comprising:

a subsystem that provides an interface between an IP based telephone control network and a public data network, the subsystem being used for registration of a subscriber'"'"'s devices on the public data network with the telephone network and enabling receiving and/or originating communication sessions from the devices through the telephone network.

2. The system of claim 1 wherein the telephone control network includes a control network for a cellular telephone system.

3. The system of claim 1 wherein the telephone-control network includes an IMS or an MMD infrastructure.

4. The system of claim 3 wherein the subsystem includes a component that emulates a P-CSCF.

5. The system of claim 1 wherein the communication sessions include VoIP telephone sessions.

6. The system of claim 1 wherein the public data network includes a public Internet.

7. The system of claim 1 wherein the public data network includes a wireless local area network.

8. The system of claim 1 wherein the subsystem provides adaptations communication protocols used on the public data network and the telephone control network.

9. The system of claim 8 wherein the subsystem provides adaptations between IETF and IMS protocols.

10. The system of claim 9 wherein the subsystem provides adaptation between IETF and IMS SIP protocols.

11. A method for providing telephone services comprising:

maintain presence in a telephone network for devices on a public data network; and

delivering calls directed to a subscriber through the telephone network to the devices on the public data network.

12. The method of claim 11 wherein the telephone network includes a wireless telephone network.

13. The method of claim 11 wherein the telephone network includes a packet switched control infrastructure.

14. The method of claim 11 wherein the telephone network includes an IP-based control infrastructure.

15. The method of claim 11 wherein the telephone network includes an IMS or an MMD infrastructure.

16. The method of claim 11 wherein the public data network includes a packet switched network.

17. The method of claim 16 wherein the packet switched network includes a public Internet.

18. The method of claim 16 wherein the packet switched network includes a wireless local area network.

19. A method for communication comprising:

providing and IP-based connection to a subscriber'"'"'s device resident on a public data network via an IMS or MMD framework.

20. The method of claim 19 wherein providing the IP-based connection to the subscriber'"'"'s device include providing a VoIP connection.

21. The method of claim 19 further comprising emulating an edge function of the IMS or MMD framework.

22. The method of claim 21 wherein emulating the edge device include emulating a P-CSCF function.

23. A communication system comprising:

a subsystem for enabling packet based telephone connections of calls placed to a wireless telephone network, the subsystem including

(a) an interface to components of the telephone network used to complete circuit-based telephone connections,

(b) an interface to components of the telephone network used to provide data network based services, and

(c) an interface to a public data network.

24. A method for communication comprising:

providing a service in a telephone network configured to deliver data services,

said service enabling

determining a first set of end devices in a wireless network,

determining a second set of end devices in a wireline network,

associating the first set of end devices and the second set of end devices,

receiving a call for one associated device, and

notifying the call to all associated devices.

25. The method of claim 24 wherein the telephone network is configured to deliver data services in an IMS or a MMD network
