Abstract Based on the GPS original technology and the electronic MAP, a new practical system solution to the vehicle information service system in GSM networks by using SMS call center is presented. The design method for the GPS/GSM system includes the structure of the regional E-MAP, the organization of the car’s terminal, the protocol of the isolated parts and a low-cost protocol which can improve the work efficiency and accelerate corporation information course.
