Abstract: Abstract: Most business support systems are equipped with emergency management system to handle system failure. But the traditional emergency system has the weakness of time lag, so the development of practical emergency system is essential. On the basis of expounding the present situation of the service system and analyzing the necessity of emergency handover management, the emergency handover management system is put forward, and then the function and the key technology of emergency handover management system are described in detail.Combining with the experimental data, the performance of the system is analyzed. The emergency handover management system innovatively realizes the automatic detection and alarm, automatic switching to emergency system, and performance trend forecast and warning. Meanwhile, the implementation cost of the system is low,which can effectively shorten the switch time, reduce or eliminate the negative effects due to system failure.
