| 摘 要： | 介绍了基于GPRS的自动车辆定位系统的数据链路，并结合GPRS数据用户的工作流程，介绍了实现链路的关键技术。从语音传输和数据传输两个方面给出了基于GPRS数据链路的自动车辆定位系统（AVLS）系统模型。着重对数据接入延时与语音负载、数据长度、数据发送间隔、系统容量等参数之间的关系进行了仿真分析。仿真结果表明,对于语音负载小、数据长度小的自动车辆定位系统，GPRS可以用来实现系统的大容量。

| Abstract: | In this paper,the Data Link of Automatic Vehicle Location System(AVLS) based on GPRS has been introduced and the key technology of accomplishing link is described according to the working flow of GPRS users.The GPRS based AVLS system model is given from both the voice and the data transmission.The relationship between the access delay and the voice traffic,data length,data transmission interval,system volume is analyzed through the simulation.It is concluded from the simulation result that for the AVLS with small voice traffic and short data length,GPRS can be used for the large-scale volume. |
