Claim 0:
1. A telematics control entity configured to determine position data of a vehicle, the entity comprising:
a network access entity configured to be connected to a cellular network and configured to transmit, in case of an emergency, a vehicle position via the cellular network to a service entity configured to collect the vehicle positions for a plurality of vehicles;
an antenna signal interface configured to receive satellite-based measurement data;
at least one position determining unit configured to determine positioning data of the vehicle based on the satellite-based measurement data, wherein the at least one position determining unit, is configured to guarantee a predefined integrity level describing a predefined risk classification of a functional safety provided by the positioning data as determined by the at least one position determining unit, wherein the at least one position determining unit is configured to provide the determined positioning data to an application entity in the vehicle requiring the predefined integrity level for the positioning data;
the at least one position determining unit has a first measurement entity configured to guarantee the predefined integrity level, to determine raw satellite position data from the received satellite based measurement data, and to transmit the determined raw satellite position data from the first measurement entity to a first positioning entity configured to determine a first position of the vehicle meeting the predefined integrity level based on the raw satellite position data;
the first positioning entity is configured to receive the raw satellite position data from the first measurement entity and is configured to determine a first position of the vehicle based on the raw satellite position data, the first position meeting, the predefined integrity level;
a bidirectional communication channel between the first measurement entity and the first positioning entity, the bidirectional communication channel is configured with an end-to-end protection between two ends of the bidirectional communication channel with no modification of information transmitted in the bidirectional communication channel between the two ends of the bidirectional communication channel;
each end of the bidirectional communication channel is configured to detect invalid, missing, or delayed information transmitted between the two ends of the bidirectional communication channel;
the first positioning entity is configured to provide the determined first position as positioning data to the application entity in a further bidirectional communication channel between the first positioning entity and the application entity, the further bidirectional communication channel is configured with an end-to-end protection between two ends of the further bidirectional communication channel with no processing or modification of information transmitted in the further bidirectional communication channel between the two ends; and
each end of the further bidirectional communication channel is configured to detect invalid, missing, or delayed information transmitted between the two ends of the further bidirectional communication channel.
