Abstract

A message generating arrangement determines whether a first communication terminal of a communication system can participate, by means of packet-switching network elements of the communication system, in a communication link in which a second communication terminal of the communication system is participating by means of circuit-switching network elements of the communication system, and generates a message on the basis of the result of the determination.

Claims

1. A device comprising:

circuitry to determine whether a first communication device can use only a packet-switch communication when the first communication device is unable to use a circuit-switch communication;

circuitry to determine whether the first communication device is to participate in a communication link with a second communication device, wherein in the link, the first communication device is to participate by use of packet-switch communication when the first communication device is unable to use circuit-switch communication and the second communication device is able to participate by use of both packet-switch and circuit-switch communications; and

circuitry to provide a message that is to indicate Combining Circuit Switched (CS) calls and Internet Protocol Multimedia Sub System (IMS) sessions (CSI) capability to the second communication device, the CSI capability to indicate that the first communication device is able to communicate with the second communication device using both packet-switch and circuit-switch communications.

2. The device of claim 1, wherein the message is compliant with Session Initiation Protocol (SIP) or Signalling System Number 7 (SS7) protocols.

3. The device of claim 1, wherein the first communication device comprises a User Equipment (UE) and the second communication device comprises a User Equipment (UE).

4. The device of claim 1, wherein the device is part of an application server unit.

5. The device of claim 1, wherein the circuitry to determine whether the first communication device is to participate in a communication link with a second communication device is to determine whether Voice Call Continuity Between Circuit Switched (CS) and Internet Protocol Multimedia Sub System (IMS) (VCC) is supported.

6. The device of claim 1, further comprising:

circuitry to decide whether communications to or from the first communication device are to be provided through a circuit-switch communication or packet-switch communication.

7. The device of claim 1, further comprising:

circuitry to decide whether a voice communication link is provided to the first communication device using a circuit-switch or packet-switch communication.

8. The device of claim 1, further comprising:

a network interface that is to provide connectivity with at least an Internet Protocol compliant network.

9. The device of claim 1, further comprising:

circuitry to determine whether a second communication device can use both packet-switch and circuit-switch communications.

10. A computer-implemented method comprising:

determining whether a first communication device can use only a packet-switch communication when the first communication device is unable to use circuit-switch communication;

determining whether the first communication device is to participate in a communication link with a second communication device, wherein in the link, the first communication device is to participate by use of packet-switch communication when the first communication device is unable to use circuit-switch communication and the second communication device is able to participate by use of both packet-switch communication and circuit-switch communication; and

providing a message that is to indicate Combining Circuit Switched (CS) calls and Internet Protocol Multimedia Sub System (IMS) sessions (CSI) capability to the second communication device, the CSI capability to indicate that the first communication device is able to communicate with the second communication device using both packet-switch communication and circuit-switch communication.

11. The method of claim 10, wherein the message is compliant with Session Initiation Protocol (SIP) or Signalling System Number 7 (SS7) protocols.

12. The method of claim 10, wherein the first communication device comprises a User Equipment (UE) and the second communication device comprises a User Equipment (UE).

13. The method of claim 10, wherein the determining whether the first communication device is to participate in a communication link with a second communication device comprises determining whether Voice Call Continuity Between Circuit Switched (CS) and Internet Protocol Multimedia Sub System (IMS) (VCC) is supported.

14. At least one non-transitory computer-readable medium, comprising instructions stored thereon, which executed by at least one processor, causes the at least one processor to:

determine whether a first communication device can use only packet-switch communication when the first communication device is unable to use circuit-switch communication;

determine whether the first communication device is to participate in a communication link with a second communication device, wherein in the link, the first communication device is to participate by use of packet-switch communication when the first communication device is unable to use circuit-switch communication and the second communication device is able to participate by use of both packet-switch communication and circuit-switch communication; and

provide a message that is to indicate Combining Circuit Switched (CS) calls and Internet Protocol Multimedia Sub System (IMS) sessions (CSI) capability to the second communication device, the CSI capability to indicate that the first communication device is able to communicate with the second communication device using both packet-switch communication and circuit-switch communication.

15. The at least one non-transitory computer-readable medium of claim 14, wherein the message is compliant with Session Initiation Protocol (SIP) or Signalling System Number 7 (SS7) protocols.

16. The at least one non-transitory computer-readable medium of claim 14, wherein when the at least one processor is to determine whether the first communication device is to participate in a communication link with a second communication device, the at least one processor is to determine whether the first communication device is to participate in a communication link with a second communication device is to determine whether Voice Call Continuity Between Circuit Switched (CS) and Internet Protocol Multimedia Sub System (IMS) (VCC) is supported.

17. A first communication device comprising:

circuitry to receive a message that is to indicate Combining Circuit Switched (CS) calls and Internet Protocol Multimedia Sub System (IMS) sessions (CSI) capability by a second communication device, wherein;

the CSI capability to indicate that the second communication device is enabled to communicate with the first communication device using packet-switch and circuit-switch communication links even though the second communication device is to participate by use of packet-switch communication when the second communication device is unable to use circuit-switch communication; and

in response to receipt of the message, circuitry to communicate with the second communication device using both packet-switch communication and circuit-switch communication.

18. The device of claim 17, further comprising:

a network interface that is to provide connectivity to at least an Internet Protocol compliant network.

19. The device of claim 17, wherein the message is compliant with Session Initiation Protocol (SIP) or Signalling System Number 7 (SS7) protocol.

20. The device of claim 17, wherein the first communication device comprises a User Equipment (UE).
