Mobile Core Network Security Technology Research And Application In Henan Mobile Intelligent Network

With the rapid development of mobile communications and related Value-added services, its security problems become increasingly serious. Relative to the wired network Mobile users of information transmission is more easily attacked, Because it's worked by Wireless channel. Meanwhile mobile core net has also changed, experienced four stages of evolution. The new generation of mobile core net is gradually flating based on IP Backbone network. This structure brings users convenience, but also it brings safety risk.Some core equipments of Mobile communication network shoulder very key task, which continued working ability and disaster survival ability will affect national economy and the people's livelihood. Intelligent Network used for Provide value-added services is just one of the key network. The reliability of Mobile intelligent network is must be considered by Mobile Network Operators.This article is on the base of new features about analyzing the GSM R4 mobile communication network including network system, signaling network, business types and accommodated disasters, analyzed the security threats and safety needs of broadband mobile network. In the development process of mobile core network, People used some of the security measures to protect network and user's information, and studied these techniques carefully. Measures include mainly three aspects, accommodated disasters backup technology, Access control technology and IP network security technology. Combined with practice of Henan Mobile intelligent network backup system this article expounds the networking and realization about accommodated disaster backup system. And it details the eleventh of Backup system expansion projects. Accommodated disaster backup mechanism of Henan mobile intelligent network has got improved In the expansion project. At the same time it details how to achieve Access control technology of Mobile intelligent network. Security about Henan Mobile intelligent network strengthened through implementation of the existing network technology.
