Abstract
Embodiments create the present method, communication module, vehicle, system, and computer program for authenticating a mobile radio device for a location-specific function of a vehicle. The vehicle comprises a transmitter designed for transmitting mobile radio signals in a mobile radio system and a receiver designed for receiving mobile radio signals in a mobile radio system. Furthermore, a control module designed for controlling the transmitter and the receiver is provided, said control module being coupled to the transmitter and the receiver, and the control module is additionally designed to convert the transmitter from a first mode to a second mode when the vehicle is parked. The transmitter consumes less energy in the second mode than in the first mode. Furthermore, a received mobile radio signal of the mobile radio device is evaluated, said signal comprising information on the identity of the mobile radio device. Finally, an authentication of the mobile radio device is carried out on the basis of the mobile radio signal, wherein the mobile radio device is authorized to use at least one location-specific function of the vehicle after a successful authentication.
