广州地铁800MHz数字集群共网系统方案研究

On Construction Scheme of the 800 MHz Digital Cluster Network in Guangzhou Metro

对广州市地面、地下800 MHz数字集群共网系统概况进行了介绍。调研分析了地铁800 MHz数字集群共网系统的服务对象、用户容量需求、话务模型及基站配置。给出了车站基站载波容量配置方案,并着重对广州市地铁与地面共网互联互通的总体原则、功能联动融合、互联物理链路、全网动态录音以及系统无线信号覆盖等方案进行了分析,提出了广州市地铁与地面800 MHz数字集群共网联动融合的具体方案。

The ground and underground 800 MHz digital cluster networks in Guangzhou City are introduced. The service object, user’s capacity demand, traffic model and base station configuration of the 800 MHz digital cluster network are investigated, a configuration scheme for carrier capacity is proposed, the interconnection between Guangzhou metro and ground PAMR （public access mobile radio） network is specially analyzed, including the functional interface division, intercommunicated physical link, total network dynamic recording, the proposal of wireless signal coverage, etc. In the end, a concrete construction scheme between Guangzhou metro and ground 800 MHz digital cluster network is put forward.
