| In recent years, with the development of mobile business, full service operation has become the inexorable trend of the development of telecommunication operators."Soft-Switch" with the features of a large capacity and high integrati on and "IP Bearing capacity" have become the main trend of the development of mobile network. With the widespread deployment of mobile softswitch network, because of the large covering of mobile softswitch equipments in the network, once the MSC Serverr is down, it will seriously influence within a local network business users. For example, when earthquakes and other major natural disasters or equipment failures caused by other factors happen, it will lead to a broader range of business interruption and make a great impact. The security and credibility problem of the mobile core network really stands out. Core network disaster recovery is already an unavoidable subject of our carriers.This paper firstly elaborated the basic concept of soft switching and soft switching disaster recovery mechanism, through analyzing all kinds of disaster recovery mechanism to choose the actual situation for Zaozhuang mobile softswitch solution of disaster recovery, and the key technologies, deploying principles and network solutions were studied. Secondly, it analysed the current situation of Zaozhuang mobile communication network. Last, it applied the results of the disaster recovery scheme to ZaoZhuang Mobile communication network. It proved that MSC POOL can be a very good solution to the core network security problems, it could be used as main references for core network disaster recovery planning, construction and operation, and that’s where its value comes from. |
