Abstract: A road toll system comprises a vehicle-mounted unit comprising a satellite navigation system implementing a position tracking function; transmitting means for transmitting position or route information to a remote server; and a unique identification device for attaching to the vehicle, and associated with the satellite navigation receiver. The road toll system function is enabled only when the identification device is present. The identification device comprises an electronic device which is adapted to alter by detachment or attempted detachment such as to prevent the road toll system function being enabled. This system increases the security of this type of system and makes fraudulent use of the system increasingly difficult.

Abstract: A road toll system comprises a vehicle-mounted unit having a satellite navigation receiver. A first data processing means determines a route taken based on satellite navigation data provided from the receiver, and the satellite navigation data is associated with a variable identity. A road toll level is derived. A second data processing means receives the road toll level provided by the first data processing means, and the satellite navigation obtains the determined road toll level from the second data processing means using the variable identity. This provides a thin client scenario (the receiver does not implement the map calculations), but with data security corresponding to a thick client solution. Thus, the map matching and trip cost computation steps are delegated by the on-board unit to an external unit, but this delegation is performed anonymously, so that no data sent for external processing compromises the privacy of the data.

Abstract: A method, device and system for generating position information in a mobile equipment provided with at least two position determination devices. Embodiments of the invention may include allocating to each position determination device at least one stored parameter value, determining a context information, depending on the context information, choosing a corresponding position determination device selection process based on the value of said at least one parameter for each position determination device, selecting a position determination device according to the chosen selection process, and activating said selected position determination device. Application to location based services may provide a better handling of available positioning resources.

Abstract: The invention relates to a road toll system using a vehicle-mounted satellite navigation receiver, from which routes taken and road prices incurred are determined. A billing system bills a user in dependence on the road prices incurred. A portable activation device transmits information concerning the owner of the portable activation device to the vehicle-mounted unit, and the vehicle-mounted unit provides information to the billing system to enable identification of the owner of the portable activation device. In combination, the portable activation device and the vehicle-mounted unit can be considered to function in a similar way to a known vehicle-mounted OBU. However, by separating the data necessary to provide user-personalization into the portable activation device, the vehicle-mounted unit can become more standard, and the user is able to drive other vehicles more easily.

Abstract: A road toll system comprises a vehicle-mounted unit having a satellite navigation receiver. A first data processing means determines a route taken 5 based on satellite navigation data provided from the receiver, and the satellite navigation data is associated with a variable identity. A road toll level is derived. A second data processing means receives the road toll level provided by the first data processing means, and the satellite navigation obtains the determined road toll level from the second data processing means using the 10 variable identity.

Abstract: A method and apparatus are disclosed wherein positioning data and road charging data depending on a vehicle position may be inserted into a combined data stream. The positioning data and road charging data may be provided with the same protocol type such as a national marine electronics association, NMEA, protocol or NMEA 0183 protocol. The combined data stream therefore comprises a mixed sequence of positioning data protocol messages and road charging data protocol messages.

Abstract: A system implements a location based service, and comprises a satellite navigation receiver implementing a position tracking function for providing the location of a user of the service. An analogue RF receiver receives satellite signals and performs at least a frequency downconversion. Correlation and decoding functions are applied to the downconverted signals for deriving location information from detected specific satellite signals. The system further comprises a server for receiving samples of the downconverted signals, and for verifying the samples are consistent with the expected satellite signals at that time and location. The invention provides a counter measure for detecting the counterfeiting of, or tampering with, the satellite signals at the receiver. A check can be made that the received satellite signals correspond to those which are expected at that location and time.

The system may include a license plate recognition system configured to obtain a license plate number of the vehicle at a first location; a database of license plate numbers and OBU information; a wireless communication system configured to send a trigger message to the OBU using the OBU information, and configured to receive a response from the OBU indicating a location of the OBU; and a verification module configured to determine whether the vehicle is equipped with the OBU. The database may include a correspondence of license plate numbers and OBU information. The verification module may determine that the vehicle is equipped with the OBU if the location reported by the OBU is within a specified distance of the first location.
