Abstract: A method providing automatic control of call diversion from a first terminal (TEG), which is coupled to a switching device (V), to any desired second terminal (MEG). The call diversion process is controlled as a function of the position of a mobile terminal (MEG) relative to a base station (BS1) which is coupled to the switching device (V). A measure for the relative position of the mobile terminal (MEG) is in this case determined on the basis of radio signals which are transmitted between the base station (BS1) and the mobile terminal (MEG).

Abstract: Messages that cannot be delivered into the mailbox of the message addressee in networked message memory units (for example, given malfunctions) are transmitted back into the mailbox of the message sender after a predetermined time. Each message is provided with message-associated information (for example, name of the message sender, time at which the message was generated). In order to avoid the same message from being repeatedly stored in the memory unit of the message sender given multiaddress transmission of one of the same message to a plurality of message addressees and given non-deliverability of the messages, the message-associated information of fed back messages are checked for identity and are not stored if identified.
