VPN Technology Study Based On Mobile Inteligent Network

Intelligent network, which was formally defined by CCITT in 1992, is one of the main tendencies of telecommunication development and is given more and more attention at home and aboard. It is called telecommunication net work of 21^st century and is the product of computer technology, telecommunication technology and market-driven according to its background and development.Value-added technology based on the 2^nd generation mobile telecommunication network is paid more attention such as mobile intelligent network which is based on mobile telecommunication network. Mobile telecommunication platforms in our country are GSM and CDMA.This thesis begins with an introduction to the concept, feature, system structure and application of intelligent network and mobile telecommunication network and followed by the application of VPN technology and tunnel technology in VPN technology. It will also explain the mobile telecommunication network application protocol by CAMEL network module and other functions entity. The protocols include CAP and MAP which are based on signal system 7.MVPN is a new service in mobile intelligent network and is paid high attention with the rapid development of GSM mobile telecommunication network and increment of mobile phone users in our country. People are hoping more functions, service, easier operation and reasonable charge when they have enjoyed the basic function of calling. So came VPDN, which made on-net and off-net call possible and provided favorable charge for group customers, increasing customer satisfaction. The thesis gives proof to network design, service feature, dialing solution, realization method and operation procedures of VPDN under the network condition in China. With the explaination to business management and business reports of VPDN business management, it will study the future development of network design at the end.
