Abstract
A communications system for registering tolls, with vehicles which have communications devices for wirefree communication between the vehicles and the toll operator which is assigned to them and has a corresponding communications device. In this context, the vehicles transmit toll information relevant to the toll operator in a toll-registration area which is assigned to the toll operator, and the toll operator determines or bills the tolls to be charged therefrom. If the vehicles communicate, by means of their communication devices, with other toll operators outside the toll registration area of the toll operator assigned to them, in order to register tolls, the exchange of toll-related information takes place only when a certificate of the assigned toll operator is successfully transmitted and on the basis of a public key or a private key.
