METHODS AND APPARATUSES FOR TRANSPORTING SIGNALLING CONNECTIVITY STATUS INFORMATION RELATING TO THE SIGNALLING CONNECTION BETWEEN A ATERMINAL AND P-CSCF IN IMS

摘要

A control device for a motor vehicle is used to store authorization data for drivers and driving times in which operation of the motor vehicle is meant to be possible. The control device is connected to an electronic engine immobilizer (6) which disables or enables operation of the motor vehicle on the basis of the stored data. This means that the motor vehicle can be started up only by a particular driver in an intended time period.
