A communication apparatus, which allows a user to communicate via a network, carries out a switch off step (SOA) in response to a switch off command. In the switch off step (SOA), the communication apparatus allows the user to select (SM2, SM3) a detach message from a list of detach messages (DML). The communication apparatus conveys (SM6, SM7) a detach message identification (MID) to the network and, subsequently, switches off (SM8). The detach message identification (MID) represents the detach message that the user has selected. The network carries out a call handling step in which the network conveys the detach message to another communication apparatus from which a call emanates that is destined for the communication apparatus that is switched off. |
