A data transmission device has a data transmitter and a wake-up receiver. The data transmitter is activable to change from an idle state into an operating state and to execute a data transmission with a communication partner in the operating state. The wake-up receiver is implemented to be ready to receive an initiation signal during the idle state of the data transmitter and to activate the data transmitter in response to the initiation signal. The wake-up receiver is further implemented to extract data transmission information from the initiation signal to determine a time for activating the data transmitter depending on the data transmission information or to activate the data transmitter such that the data transmitter executes the data transmission depending on the data transmission information.

Data transmission device and a method for activating a data transmission

A mobile device communicates with a base station according to a communication protocol, the communication protocol having a first message for signaling a readiness of the base station for a normal login operation of the mobile device with the base station and a second message for signaling a readiness of the base station for an ad-hoc login operation of the mobile device with the base station, so that the ad-hoc login information of the ad-hoc login operation can be distinguished from the normal login information of the normal login operation. To this end, the mobile device has a receiver, an interpreter and a processor, which is formed so as to perform the ad-hoc login operation when the readiness of the base station for an ad-hoc login operation is signaled.
