Chengdu Mobile Core Network Disaster Recovery System Design And Implementation

At present, more and more mobile phone users in China, the increasingly high penetration rate, people depend on the public mobile communication network is more and more strong. Mobile phones have become an indispensable tool in people’s life. At the same time, network operation and maintenance point of view,the network quality is the lifeline of the operators, in the face of disaster is the life channel emergency rescue and disaster relief, but how in the disaster when fast start backup system, at the same time reduce the starting difficulty, ensure accurate operation, is facing the severe test of the network service level. So thedesign and development of a set to conform to the mobile core network disaster tolerance system increasingly urgent demand, the system needs to be able to achieve orange yellow blue emergency services, performance of early warningservice, POOL disaster emergency backup services, rights management system,the system log management and other functions, so as to adapt to the rapid development of the demand for mobile communication core network.Disaster recovery system is designed to help emergency rescue personnel toaccurately generate various types of equipment of the instruction set, rapid examination of each element load state, quickly issued executive orders;performance index inspection element, POOL net element backup. Including three major business modules: red orange yellow blue emergency drills,performance of early warning exercises, POOL backup emergency drills, and other functions, such as rights management, log management etc.. Systemdesign in accordance with the module, according to the actual needs and user requirements, design for the client server architecture, namely C/S architecture.The server, including the application of all functions, and provide access to external call interface, the interface includes: red orange yellow blue emergencyinterface, performance alarm interface, POOL interface, disaster recovery fault range interface, network element management interface, user management interface. Windows Server 2003 and Net Framework 4 framework based onsoftware operating system; using SQL Server 2008 as the system data storage;choose Socket bottom interface interaction, using Socket interface layer, the establishment of the TCP protocol to connect and interact in accordance with the rules of interface equipment, obtain the network data and command issued, implementing instruction key response.Through the development of more than a year of use, the actual needs of the system and the current network to adapt, to meet the basic practical function,relatively high degree of. The system realize the ultimate success of Chengdu mobile core network disaster tolerance control.
