A process, a control center, and a terminal device are proposed for transmitting messages to terminal devices in a, in particular, wireless, telecommunications system with a control center and with terminal devices. The transmission protocol is frame structured in the time domain. In the transmission protocol, the terminal devices ignore messages from the control center during a single frame, or several consecutive frames. The following steps are carried out in order to transmit a message to one terminal device or to a plurality of terminal devices: First, a number of terminal device groups which includes the majority of the terminal devices are formed by the control center. Each terminal device belongs to exactly one terminal device group and all terminal devices of a terminal device group are ready to receive messages during the same frame. Second, the message that is to be sent is transmitted to each of at least one terminal device group during one possible frame.
