Risk Assessment And Security Protection Of Mobile Packet Switch Core Network

As China's economic and social development, basic social and global status of the mobile data communications network has become increasingly prominent, the state, society, public is much more dependent on mobile data communication network than ever before, and it cannot be departed from our daily work and life.With the development of technology, and diverse types of mobile data services, stimulate the usage of data services. As mobile communications Operator, it can not only provide high availability of mobile data network services for users, but also ensure the security of business applications in network. On the contrary, business applications make the mobile communications business operators higher demands. Therefore, this article is mainly about the research of enhance mobile communication packet domain core network security.We will firstly introduce the background research, including mobile telecommunication industry development and importance of research.Then,we take the overview of 2/3G packet switched domain system, and key technology research status and significance. Also introduced the traditional telecommunications network, data-communication network, packet core network security, mobile phone virus malware risks.Base on the knowledge, the first systematic analysis of the packet-switched domain core network security risks and safety program discusses one whole. Then, combined with the existing network of important business process links actual given a feasible solution. Finally, based on the use of the existing network of mobile malware assessment, in-depth study proposes a multi-layer cell phone Anti-Malware System.The fourth part is a summary of the paper part, mainly on the basis of the study summarize, given the research, conclusion of the practice and further suggestion.
