Method for updating call redirection destinations in a communication network
First Claim
1. A method for updating call redirection destinations in a communication network, the method comprising the steps of:
- storing, in a memory associated with a first subscriber terminal, both a call redirection destination, which has been changed by a user entry at the first subscriber terminal, and a point of origin of a call redirection as call redirection information for a second subscriber terminal which forms the point of origin of the call redirection;
sending the stored call redirection information to a control unit associated with the second subscriber terminal;
checking, via the control unit, whether a call redirection indicated by the call redirection information has been set up;
storing the call redirection information in a memory associated with the second subscriber terminal and setting up the call redirection based on a result of the step of checking; and
operating the first subscriber terminal in a stand-in mode, wherein once a stand-in destination selected for the first subscriber terminal has been entered, messages containing updated call redirection information are sent to the second subscriber terminal which had previously been set up as the point of origin of the call redirection to the first subscriber terminal.

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.

7. A method for updating call redirection destinations in a communication network, the method comprising the steps of:
-
storing, in a memory associated with a first subscriber terminal, both a call redirection destination, which has been changed by a user entry at the first subscriber terminal, and a point of origin of a call redirection as call redirection information for a second subscriber terminal which forms the point of origin of the call redirection;
sending the stored call redirection information to a control unit associated with the second subscriber terminal;
checking, via the control unit, whether a call redirection indicated by the call redirection information has been set up;
storing the call redirection information in a memory associated with the second subscriber terminal and setting up the call redirection based on a result of the step of checking;
sending messages containing the call redirection information to a further first subscriber terminal, wherein the call redirection information contained in the messages includes additional indications of one of activation and deactivation of a call redirection;
searching a respective memory associated with the further first subscriber terminal for a comparison between call redirection information stored in the respective memory and the call redirection information sent to the further first subscriber terminal contained in the messages; and
updating the call redirection information stored in the respective memory associated with the further first subscriber terminal based on a result of the comparison.

updating the call redirection information stored in the respective memory associated with the further first subscriber terminal based on a result of the comparison; and
sending the messages containing the call redirection information, within a call acceptance group with which the further first subscriber terminal provided for a call redirection originating from the second subscriber terminal and the second subscriber terminal are associated, from the second subscriber terminal to the further first subscriber terminal.
