【摘要】：目前,我国移动电话用户越来越多,普及率越来越高,人们对于公众移动通信网络的依赖性也越来越强。手机已经成为人们生活中不可或缺的重要工具。同时,就网络运维角度来看,网络质量是运营商的生命线,在灾难面前更是抢险救灾的生命通道,但如何在灾时快速启动容灾系统,同时降低启动难度,确保准确操作,是网络服务水平面临的严峻考验。所以设计开发一套符合移动核心网容灾系统的需求也越来越迫切,系统需要能够实现红橙黄蓝应急服务、性能预警服务、POOL容灾应急备份服务、系统权限管理、系统日志管理等功能,以此来适应移动通信核心网的快速发展需求。容灾系统系统旨在帮助应急抢险人员准确地生成各类设备的指令集,迅速检查各网元负荷状态,快速下发执行指令;检查网元的性能指标,进行POOL内网元的备份。主要包括三大业务模块:红橙黄蓝应急演练、性能预警演练、POOL容灾备份应急演练,以及其他功能,如权限管理、日志管理等。系统按照模块化设计,根据实际需求和用户要求,设计为服务器-客户端架构,即C/S架构。服务器端,包含所有的应用功能,并向外部提供访问调用接口,这些接口包括:红橙黄蓝应急接口、性能预警接口、POOL容灾接口、故障范围接口、网元管理接口、用户管理接口。软件操作系统基于Windows Server 2003以及Net Framework 4.0框架;采用SQL Server 2008作为系统的数据存储;选择了Socket底层接口交互,利用Socket底层接口,建立TCP协议连接,按照设备接口规则进行交互,获取网络数据以及下发人机指令,实现指令一键响应。通过一年多的开发使用,该系统与现网的实际需求相适应,功能基本满足,实用化程度比较高。该系统最终成功实现成都移动核心网全容灾管控。
[Abstract]:At present, the number of mobile phone users in China is increasing, the popularity rate is increasing, and the dependence of people on the public mobile communication network is becoming increasingly strong. Mobile phones have become an indispensable and important tool in people's lives. At the same time, From the point of view of network operation and maintenance, network quality is the lifeline of operators, and it is also the life passage of emergency and disaster relief in the face of disaster. But how to start disaster recovery system quickly, at the same time, reduce the difficulty of starting, and ensure accurate operation. It is a severe test of network service level. Therefore, it is more and more urgent to design and develop a set of disaster recovery system in line with the mobile core network. The system needs to be able to realize the red, orange, yellow and blue emergency services, and the performance early warning service, Pool disaster recovery emergency backup service. System privilege management, system log management and other functions to meet the rapid development of mobile communication core network. Disaster recovery system to help emergency rescue personnel to accurately generate instruction sets of all kinds of equipment, Check the load status of each network element quickly, issue the execution instruction quickly; check the performance index of the network element, carry on the backup of the network element inside the POOL. It mainly includes three major business modules: red, orange, yellow and blue emergency drill, performance early warning exercise, pool disaster recovery backup emergency drill, And other functions, such as permission management, log management, etc. According to the modular design, according to the actual requirements and user requirements, the system is designed as a server-client architecture, that is, the C / S architecture. The server side includes all the application functions. And provide external access call interfaces, including: red, orange, yellow and blue emergency interface, performance warning interface Pool disaster recovery interface, fault range interface, network element management interface, User management interface. The software operating system is based on Windows Server 2003 and Net Framework 4.0 framework; SQL Server 2008 is used as the data storage of the system; Socket bottom interface is selected to interact, and Socket bottom interface is used to establish TCP protocol connection. In accordance with the device interface rules, the system interacts with each other, acquires the network data and sends out man-machine instructions, and realizes the one-button response of the instruction. After more than a year of development and use, the system is suitable for the actual needs of the existing network, and the functions are basically satisfied. The system successfully realizes the full disaster recovery control of Chengdu Mobile Core Network.
