【Abstract】 This paper discusses the GPRS technique and the network structure of GPRS system. The advantages of the GPRS technique in vehicle navigation system are summarized by comparing the traditional GSM short message service with the GPRS service. A server example of vehicle navigation system with the GPRS technique is demonstrated in this paper. This example is programmed with VC. The frame model of the server is elaborated. At last the developing prospect of GPRS technique in vehicle navigation system is analyzed briefly.更多还原
