Abstract:
1. A message generating arrangement, comprising: 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.
