A method for starting a short message transmission in a cellular communication system, a cellular communication system, and a cellular communication system subscriber location register includes the subscriber location register which stores information on the fact that at least one short message service center stores short messages to be transmitted to a subscriber to whom the messages cannot be transmitted for the time being, and the subscriber location register of the subscriber which transmits to at least one short message service center a short message transmission starting message when it is again possible to transmit short messages to the subscriber.
