Abstract

Before a call is set up in mobile radio networks, each calling vehicle subscriber notifies his identity to the central station in the form of an identification code. Since this identification code can be intercepted, there is the risk that eavesdroppers may make radiotelephone calls at the expense of an authorised subscriber. To prevent this, the destination dialling information transmitted by the calling vehicle subscriber is transmitted following encryption 3 along with a fixed key 4 which is uniquely allocated to this vehicle subscriber only. In the central station, the subscriber-specific fixed key 7 is selected by the identification code of the calling subscriber, which code was previously transmitted in unencrypted form from a fixed key file 6 containing all the inverse fixed keys and, with the aid of said fixed key, the destination dialling information is decrypted 8. Any international indicator digit of a destination dialling code is transmitted in unencrypted form. To prevent identification of the fixed key of an external subscriber, the module 4 containing the subscriber-specific fixed key and the encryption module 3 are disposed in a technically inseparable and inaccessible manner, and are interconnected, in each station (Fig. 4). <IMAGE>
