Servicing control units of motor vehicles via mobile radio
First Claim
1. A method for private wireless exchange of device data between a control unit installed in a motor vehicle and a vehicle-external computing device, comprising:
- registering a mobile radio module of the motor vehicle with a private mobile radio cell that only provides device data to and from the vehicle-external computing device, said private mobile radio cell being different from all mobile radio cells of public radio networks, and not permitting registering conventional mobile phones with IMSI (International Mobile Subscriber Identity), said mobile radio module being registered using a SIM (Subscriber Identification Module) card, the SIM card is an embedded Universal Integrated Circuit Card (eUICC) that is permanently installed in the motor vehicle and data transfer between the private mobile radio cell and the controller is set up by storing an access profile in the eUICC at least once or activating an access profile already stored in the eUICC,setting up data transfer between the control unit and the mobile radio module of the motor vehicle, andtransmitting device data provided to the mobile radio module by the control unit of the motor vehicle, to the private mobile radio cell with which the mobile radio module was registered by the SIM card, wherein after the device data is transmitted, the access profile changes the data transfer set up of the mobile radio module for registering the mobile radio module in one of the public mobile radio networks.

Abstract
In a method for wireless exchange of device data between a control unit of a motor vehicle and a vehicle-external computing device, a mobile radio connection is established between a mobile radio module of the motor vehicle and a mobile radio cell of a radio station coupled with the computing device. The device data are transmitted via the mobile radio connection. The radio station provides a private mobile radio cell which is different from all mobile radio cells of public mobile radio networks able to reach the motor vehicle. To establish the mobile radio connection in the motor vehicle, the mobile radio module is reconfigured for registering with the private mobile radio cell by using a SIM card.
