摘　　要：为实现城市轨道交通综合通信网长期稳定地运作,同时为帮助在综合通信网规划设计及运营维护过程中对可靠性的把控,从3个方面对综合通信网的可靠性进行分析研究。首先分析综合通信网可靠性的定义,并提出适合于综合通信网的可靠性计算指标以及常用的可靠性系统分析模型;其次根据综合通信网的自身特点分两层分析综合通信网自身因素主导下的可靠性;最后提出提高其可靠性的两种措施。In order to realize reliable operation of integrated communication network in the planning and design stage and maintain long-term stability of the network during the service stage, this paper analyzes the reliability of the integrated communication network from three aspects. Firstly, it analyzes the definition of the reliability, the calculating indexes of the reliability and the typical system reliability analysis models. Then, it puts forward the reliability of the integrated communication network dominated by the factors of the network itself in two layers based on characteristics of the network. Finally, it presents two measures to improve the system reliability.
