ABSTRACT:
In a mobile communications system10, a message is sent to a mobile terminal16which transmits an acknowledgement signal if the message is received. If the system10does not detect an acknowledgement signal, it transmits a high margin notification signal to the mobile terminal16to notify the terminal that an attempt was made to send the message. When the mobile terminal16has received a notification signal and subsequently comes within range of lower margin signals from the system, it sends a registration signal to the system. The system may then retransmit the message to the mobile terminal16.
