集群移动通信系统虽然具有话音通信调度能力但是缺乏用户定位导航能力，ＧＰＳ（全球定位系统）虽然具有导航定位能力但是缺乏用户之间的通信能力．因此，如何将ＧＰＳ与集群通信系统有机结合，取长补短，组成动态的自动车辆定位调度系统具有十分重要的意义．作者在研究Ｍｏｔｏｌｏｒａ智慧网的基础上，分析了实现自动车辆定位调度系统需要解决的几个技术难题：识辨和提取控制信令和话音信息，自动建立ＧＰＳ数据链路以及信道负载平衡等，并给出了解决方案．实践结果已证明了这些方案是可行的．
Although trunked mobile communication system has the ability of voice communication scheduling but lacks the user positioning and navigation ability, GPS (Global Positioning System) lacks the ability of communication between users though it has the capability of navigating and positioning. Therefore, how to combine the GPS with the cluster communication system and learn from each other to form a dynamic automatic vehicle positioning and scheduling system is of great significance. Based on the study of Motolora wisdom network, the author analyzes several technical problems that need to be solved to realize automatic vehicle positioning and dispatching system: identification and extraction of control signaling and voice information, automatic establishment of GPS data link and channel load balancing, etc. Given the solution. Practical results have proved that these solutions are feasible.
