摘  要:随着信息技术的快速发展,通信网络在社会的各方面发挥着越来越重要的作用。然而,面对汛情、台风、地震、暴雪等自然灾害时,通信网络却常常呈现出一定的脆弱性,从而造成长时间的通信隔断和大量的抢修盲区,加剧了灾害抢救的难度。因此,本文以中国移动海南公司搭建的应急指挥调度系统为基础,介绍了系统的整体架构、相关技术以及应用场景。该系统可以有效地解决灾害情境下通信网络的指挥调度问题,优化了灾害抢救流程,减少了抢修时间,提高了用户满意度。

Abstract: With the rapid development of information technology, communication network plays an increasingly important role in all aspects of society. However, in the face of natural disasters such as flood, typhoon, earthquake, Blizzard and other natural disasters, the communication network often presents a certain vulnerability, resulting in long-term communication isolation and a large number of repair blind areas, which aggravates the difficulty of disaster rescue. Therefore, based on the emergency command and dispatch system built by China Mobile Hainan Company, this paper introduces the overall architecture, related technologies and application scenarios of the system. The system can effectively solve the command and scheduling problem of communication network in disaster situation, optimize the disaster rescue process, reduce repair time, and improve user satisfaction.

随着智能终端的广泛普及和移动通信市场的快速发展,人们可以随时随地的通过移动网络来获取、分享、处理、交换信息。然而,各类极端天气、社会事故、群体事件等都将对通信网络造成重大影响,从而导致部分通信故障,通信服务能力快速降低。因此,人们对于灾害情景下通信服务能力的稳定性、自愈性、可靠性等方面提出了更高要求。在灾害情境下,通信网络的指挥调度工作主要面临三个方面的问题:一是由于通信网络的部分受损,将会导致大量的信息隔断,而信息获取的不及时将会给网络抢修工作带来困难,如计划的制定,信息的反馈等[1];二是通信网络中受损网络设备(如通信基站)信息需要进行人工的上报,常常会出现误报,漏报、重复上报的情况,容易造成抢修盲区和资源冲突;三是灾害发生后,政府和公众对灾区的通信需求快速增长[2],同时话务量和流量也将出现“喷井式”爆发的情况,因此在做好抢修工作的基础上如何保证现有用户的通信需求也是运营商目前亟待解决的问题。……
