The MSC-POOL Disaster Warning System Research And Implementation

In conventional mobile communication network structure in order to facilitate a smooth evolution to 3G networks, the current version of the core network based 3GR4 soft switch network communication operators have been large-scale network applications. For carrying soft switch architecture and control characteristics of large capacity core network MSC-SERVER phase separation so that the safety of the equipment becomes more and more important. Based on the traditional MSC board and port security backup mechanism cannot meet the security requirements soft switch network, and backed the principle of MSC POOL itself has, making network security greatly improved when a POOL within the MSC SERVER failure lead to bearer service time, POOL automatically activated the emergency measures will fail server business switching to other SERVER, such as disaster recovery measures for routine maintenance can bring great benefits to avoid major failures due to equipment to bring loss of traffic, it will not affect the user perception. But in actual routine maintenance work, not only just equipment failures we encounter significant, there are all kinds of emergencies, such as: When an individual regional event earthquakes, floods, snowstorms and other such unexpected events the results brought yes, a certain region sudden traffic growth may reach the limit network can carry. Maintenance personnel must react to this in the first time, make the necessary measures to avoid the avalanche effect to bring down the network. Normally, we deal with the network abnormalities caused by various emergencies, such as major events and holidays when the need for emergency maintenance personnel by Fairchild acquisition targets, indicators presented by the situation, analyze what emergency measures to take on what network elements, then execute the script prepared in advance. However, while the core network indicators are more manual analysis process is complex, prone to error, error if the response is not timely maintenance personnel or the implementation process, the network will bring immeasurable impact.It is discussed in this paper under the current network MSC-POOL situation, the core network element face of unexpected events, major events or holidays in emergency response, and how to complete the emergency plan in response to the rapid and efficient and accurate.
