In the control center, the segments of the road traffic network which are affected by the traffic information are either coded using a location coordinate table, available in the control center, in a form which represents the location of the segments, or are coded using a segment table, available in the control center, in a form which represents the identity of the segments without their location. The control center transmits to the terminal a selection information item which indicates which of the two above codings is used in the transmitted information.

Abstract: A secure and efficient key management system for utilizing a service key for retrieving service data transmitted to a terminal from a service center via a communication channel. A service key is inserted into a terminal and is used to enable the decryption of the received encrypted service data from the service center. The service center requests and obtains a coding key from a trust center when the service center receives a service key transmission request from the from the terminal. The service key transmission request includes a terminal identity number. The service center forwards the request to the trust center which returns the coding key associated with a decoding key corresponding to the specific terminal. The service center encrypts the service key with the coding key and transmits the service key to the terminal. The service key is decrypted in the terminal using the decoding key input to the terminal by the terminal manufacturer.

Abstract: The invention relates to a process and a device for forwarding non-speech-bound information between a mobile communications network and any other communications network. To allow data packets data to be sent, regardless of its receiver address, to the involved communications network, the transmission route for the forwarding of the information is established as a function of the identification code of the data packet one logical transmission channel is assigned to each identification code, and each logical transmission channel is bound to exactly one physical transmission channel. For this purpose, an identification code is assigned to each incoming logical transmission channel. The logical transmission channels from the mobile communications network then are permanently connected to selected outgoing physical transmission channels to different communications networks.
