Embodiment Construction

[0038] figure 1 A road toll system to which the present invention can be applied is shown.

[0039] GPS data is captured by GPS receiver 1 . Decode this data into location data (longitude-latitude). The position data is stored together with timing (clock) data in a memory 2 in the form of a smart card. Periodically send a batch of stored data to the back-end road toll server 4, as shown in batch download 6. Ideally, this would be done over GSM functionality (General Packet Radio Service "GPRS" or third generation mobile telephony "3G") using a cellular modem 8 . The backend server is able to reconstruct the distance traveled from this data.

[0040] The server 4 also contains a database of road prices which are valid at a particular time. Finally, the total price is calculated and the driver gets the list (eg, by month).

[0041] In order to prevent the data from being tampered by the user, the data is exchanged cryptographically (eg DES or 3DES) between the GPS decoder ...

Abstract

A location tracking unit for use with a location based service system is presented. The location tracking unit comprises: a navigation receiver adapted to implement a location tracking function; data processing means adapted to determine an occupied location according to a first location matching process, the first location matching process using navigation data from the navigation receiver and a first set of geographic data; and data processing means adapted to verify the integrity of the first location matching process based on a second location matching process using navigation data and a second set of geographic data.

Description

technical field [0001] The present invention relates to a location-based service system that implements a device location-based process. Background technique [0002] Location-based services rely on the combined use of telecommunications and informatics (also known as "telematics"). [0003] Telematics applications utilizing vehicles are currently an area of ​​particular interest. For example, vehicle telematics systems can be used for a variety of purposes including collecting road tolls, managing road usage (intelligent transport systems), tracking fleet location, recovering stolen vehicles, providing automated collision notifications, location-driven driver information services, and On-board early warning notification alarm system (vehicle accident prevention). [0004] Road pricing is considered the first possible high-volume market for vehicle telematics systems. Telematics is now starting to enter the consumer vehicle environment as a multimedia service box for clos...
