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 of the communication system is enabled to participate, by means of only packet-switching network elements of the communication system in an absence of circuit-switching network elements in the first communication terminal, 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

a message generating device configured to generate, if it has been determined that the first communication terminal is enabled to participate, by means of only the packet-switching network elements, in a communication link in which the second communication terminal is participating by means of the circuit-switching network elements, a message comprising the information 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.
