The Design And Implementation Of Mobile Comprehensive Emergency And Warning System

The safety and stability of mobile communication network the operation is very important for national security and social stability.In order to establish and perfect the national communication security and communications emergency work mechanism, in 2006 the State Council published The National Communication Support Emergency Plan.The telecomm-unication operators are establishing their own network emergency plan to improve emergency warning level.Currently, the situation of emergency warning is that mobile network optimization staff uses equipment monitoring software provided by equipment manufacturers to realize optimization. The method is using the manual way, monitoring large character information, artificial warning and adjusting network parameters through the manual command line.To emergency warning process automatically and intelligently, this paper designs and realizes mobile comprehensive emergency and warning system.System using C/S architecture. Server and clients communicate using protocol based on UDP.It mainly divides into alarm collecting process, the server process and the client process. Alarm collection peocess having the highest network simultaneity demand use IOCP as IO model, the paper presents the design of memory pool and efficient buffer solution improve system throughput.The server process realize warning task scheduling, judgment and the early warning notice and warning implementation. The client process majors in data statistics and report generation as well as to the server process configuration, including task configuration,warning threshold configuration, message template editing,warning instructions generation etc.Finally,it forecasts the important parameter of the network operation CP load using support vector machine regression forecast method. The system uses Microsoft Visual Studio 2008 as a development platform, using C++and C# as the development language, using Microsoft SQL Server 2005 as database.The system has been in operation for 6 months, which can real-time monitoring 100 network nodes. Data acquisition throughput is not less than 854 KB/s, alarm data collection period is 5 minutes and a warning process cycle is 15 minutes. The MAPE of CP load forecasting is 1.7912%.Systen operates stably and reliably, achieving the anticipated goal.
