In a mobile communications system, a message is sent to a mobile terminalwhich transmits an acknowledgement signal if the message is received. If the systemdoes not detect an acknowledgement signal, it transmits a high margin notification signal to the mobile terminalto notify the terminal that an attempt was made to send the message. When the mobile terminalhas 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 terminal

High margin notification method and apparatus

In a mobile communications system , a message is sent to a mobile terminal which transmits an acknowledgement signal if the message is received. If the system does not detect an acknowledgement signal, it transmits a high margin notification signal to the mobile terminal to notify the terminal that an attempt was made to send the message. When the mobile terminal has 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 terminal
