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.

a determining device configured to determine whether a first communication terminal is configured to participate, by use of only packet-switching network elements and not configured to participate by use of circuit-switching network elements, in a communication link in which a second communication terminal is configured to participate by use of circuit-switching network elements; and

a message generating device configured to generate, if it has been determined that the first communication terminal is configured to participate, by use of only packet-switching network elements in a communication link in which the second communication terminal is configured to participate by use of circuit-switching network elements, a message comprising information to indicate that the first communication terminal supports that a packet-switched communication link and a circuit-switched communication link is enabled to exist in parallel between the first communication terminal and the second communication terminal.

2. The message generating arrangement according to claim 1, wherein the message generating arrangement is arranged in the first communication terminal.

5. A message generating arrangement, comprising:

a determining device configured to determine whether a first communication terminal is both configured to participate, by use of Internet Protocol Multimedia Sub-System (IMS) network elements and not configured to participate by use of circuit-switching network elements, in a communication link in which a second communication terminal is configured to use Combining Circuit Switched calls and Internet Protocol Multimedia Sub-System (CSI); and

a message generating device configured to generate, if it has been determined that the first communication terminal is configured to participate by use of IMS network elements in a communication link in which the second communication terminal is configured to use CSI, a message comprising radio environment information to indicate that the first communication terminal is enabled to configured for participation in a communication link by use of circuit-switching and packet switching network elements simultaneously.

6. The message generating arrangement according to claim 5, wherein the message generating arrangement is arranged in the first communication terminal.

7. The message generating arrangement according to claim 5, wherein the message comprises radio environment information to indicate that the first communication terminal supports Combining Circuit Switched (CS) calls and Internet Protocol Multimedia Sub-System (IMS) sessions (CSI).

8. A message generating arrangement, comprising:

a determining device configured to determine, at a point of time when a first communication terminal has not yet requested to set up a multimedia communication session, whether the first communication terminal is enabled to participate, by use of only packet-switching network elements in a communication link in which a second communication terminal is enabled to participate by use of circuit-switching network elements and a message generating device configured to generate, if it has been determined that the first communication terminal is enabled to participate by use of only the packet-switching network elements in a communication link in which the second communication terminal is enabled to participate by use of the circuit-switching network elements, a message comprising information to indicate that the first communication terminal supports that a packet-switched communication link and a circuit-switched communication link is enabled to exist in parallel between the first communication terminal and the second communication terminal.

9. The message generating arrangement according to claim 8, wherein the message generating device is configured to generate the message when the first communication terminal is registered with a network element for utilizing packet-switched communication links.
