Abstract: A method for updating call redirection destinations, in which a call redirection destination which has been changed by a user entry on a first subscriber terminal is stored for a second subscriber terminal, which forms a point of origin for a call redirection, in an associated memory together with the point of origin of the call redirection as call redirection information. The stored call redirection information is sent to a control unit associated with the second subscriber terminal. The control unit checks whether a call redirection indicated by the call redirection information has been set up. A call redirection is set up on the basis of the result of the check.

Abstract: A method is provided for implementing call acceptance groups extending between network nodes in a communications network having a plurality of network nodes. An arrival of a call for a terminal which is coupled to a first network node and has an assigned call acceptance group is also signaled to all of the other network nodes that are to be determined and to which terminals of the call acceptance group are coupled. The network nodes subsequently cause that information to be displayed at the terminals of the call acceptance group which are coupled to the network nodes, and permit the call to be accepted at each of those terminals.

Abstract: A method for call forwarding in a communications network in which a single first subscriber line and at least one second subscriber line provided for a call transfer originating from the first subscriber line are assigned to a call acceptance group. A call made to the first subscriber line is forwarded within the call acceptance group to the second subscriber line and/or is signaled there for call answering.

Abstract: A method in which at least one memory, which is associated with at least one first subscriber connection, is used to store a cross-reference to a second subscriber connection whose state is signaled at the first subscriber connection. For allocation of the first subscriber connection to a first communications system and allocation of the second subscriber connection to a second communications system, the at least one first subscriber connection is allocated group information, and the group information is stored, for message compression, in a memory which is associated with the second subscriber connection. Furthermore, in the event of a state change of the second subscriber connection, a message relating to the state change is sent with the group information to the first communications system, for transmission of a message with information about the state change to the first subscriber connection.
