Wireless Data Transmission On Enterprise Application Using CDMA1X Network

With the development of science and technology, the demands for wireless network are getting more and more to enterprise. Because CDMA1X has higher speed and low cost, so most enterprises build their own Intranet using CDMA1X and VPDN for mobile OA, and data integration. But there are tow problems in present system: first is the present system can not verify the IMSI, it will cause security issues, the second is the present system can not configure IP address by dialup username instead of dynamic configure IP address. And it will effect the application that needs static IP address. So there is need a solution that security, low cost, high performance.In order to resolve the problems, this paper proposes a software solution that supports CDMA1X system of China Unicom. Use CDMA IX and VPDN to build enterprise Intranet, and add AAA and DHCP server to LNS for verify user's IMSI and getting static IP address. So it resolved the problems with low cost, security, high performance.
