【摘要】：随着全球范围内的恐怖袭击、自然灾害等突发公共事件的不断发生,应急响应行动越来越受到各国政府的重视。在汶川大地震等救灾抢险行动中,应急通信发挥了举足轻重的作用。应急通信能力是应急响应行动的重要保障,其业务能力的好坏直接关系到应急响应行动的成败。构建一个具有强大而丰富的通信业务能力的应急通信网,引起了通信领域的广泛的关注和重视。即时消息业务凭借其通信表达能力强、占用通信资源少等诸多优点,成为了应急通信网多种通信业务中不可或缺的一种。本文围绕应急通信网即时消息服务器的设计与实现,论述了应急通信网中即时消息业务的应用场景、功能需要和关键技术。本文给出了一个即时消息服务器的需求分析、设计开发、测试等相关工作的完整论述。本文首先介绍了应急通信与即时消息业务等相关的概念、协议与技术。然后分析了应急通信即时消息服务器的业务需求,随后,据此重点论述了即时消息服务器的总体设计与详细设计。从业务实现的三种不同模式、系统软件的不同层次等角度详细介绍了即时消息服务器的设计实现工作。最后,从功能完备性、性能可用性等方面对应急通信网即时消息服务器进行了测试。
[Abstract]:With the global terrorist attacks, natural disasters and other sudden public events continue to occur, emergency response action has been paid more and more attention by governments. In the Wenchuan earthquake and other rescue operations. Emergency communication plays an important role. Emergency communication capability is an important guarantee of emergency response action. The quality of its business capability is directly related to the success or failure of emergency response operations. Instant messaging services have many advantages, such as strong communication expression ability, less communication resources and so on. It has become an indispensable service in emergency communication network. This paper focuses on the design and implementation of the instant messaging server in the emergency communication network, and discusses the application scene of the instant message service in the emergency communication network. Functional requirements and key technologies. This paper gives a complete description of the requirements analysis, design and development, testing and other related work of an instant messaging server. This paper first introduces the concepts, protocols and technologies related to emergency communication and instant messaging services, and then analyzes the business requirements of the emergency communication instant messaging server. Based on this, the paper focuses on the overall design and detailed design of the instant messaging server from three different modes of business implementation. The design and implementation of the instant messaging server are introduced in detail from different levels of the system software. Finally, the instant messaging server of the emergency communication network is tested from the aspects of function completeness and performance availability.
