Abstract
A method for starting a short message transmission in a cellular radio network, a corresponding cellular radio network, and a subscriber register for a cellular radio network. The subscriber register is equipped for sending a short message transmission start message to at least one short message service centre. For delaying start messages for short message transmission for a given subscriber, the subscriber register includes a memory, a control, a transmitter responsive to the control for sending start messages for short message transmission for a given subscriber to different short message service centres after delays of variable duration, and a delay producer, responsive to the transmitter, generating a variable delay for delaying sending of start messages for short message transmission for a given subscriber by the transmitter for a desired period of time.
