1. A communication network unit comprising:

  • a memory configured to store, for each communication terminal of a plurality of first communication terminals which are each associated with a same user identification, information about communication capabilities of the respective communication terminals;

    a determining unit configured to determine which communication capabilities are available for communicating with a user by reading from the memory the information about the communication capabilities of the plurality of first communication terminals associated with the user identification of the user; and

    a first signaling unit configured to transmit to a second communication terminal a data message that indicates which communication capabilities, as determined by the determining unit, are available for communicating with the user,wherein a communication connection is established between a first communication terminal of the plurality of first communication terminals and the second communication terminal, and the determining unit is further configured to determine which communication capabilities of the first communication terminal can be used for communicating with the second communication terminal and to determine which of the communication capabilities of the other communication terminals of the plurality of first communication terminals can be used for communicating with the second communication terminal, andwherein the first signaling unit is further configured to signal to the second communication terminal the communication capabilities of the first communication terminal that can be used for communicating with the second communication terminal as being available and to signal the communication capabilities of the other communication terminals of the plurality of first communication terminals that can be used for communicating with the second communication terminal as being conditionally available, anda second signaling unit configured to notify communication terminals of the plurality of first communication terminals about the communication connection between the first communication terminal of the plurality of first communication terminals and the second communication terminal,wherein the second signaling unit is further configured to notify communication terminals of the plurality of first communication terminals that have communication capabilities that can be used for communication with the second communication terminal, about the communication connection between the first communication terminal of the plurality of first communication terminals and the second communication terminal, andwherein at least one of the communication terminals of the communication terminals that are being notified about the communication connection comprises a reporting unit configured to inform the user about the communication connection.
