摘　　要：主要研究在CDMA2000 1xEV-DO网络中建立基于BCMCS的移动广播网络方案,具体内容包括了BCMCS的介绍,广播方案的网络拓扑、基本流程图和关键技术等。方案将应用于定位信息分发业务当中,实现将从大众导航与位置服务信息处理服务中心获得的精密定位信息实时送达到用户移动终端上,解决定位信息分发业务无法实现大规模用户和快速实时送达的不足,实现更高效的传输。This paper mainly focuses on creating a mobile broadcast scheme based on BCMCS in DCMA2000 lxEV-DO. Introduction of BCMCS, network topology of broadcast scheme, basic flowchart and key technologies are described in this paper. The broadcast scheme is used in location information distribution services. Precise location information getting from the public navigation and location-based services information processing service center will be transmitted to MS in real time. It can also improve the user scale in location information distribution services, making the transmission more efficient.
