Case Study:The Planning And Implement Of Expansion For Ip Specific Bearing Nets

Based on the guidance of provincial expansion of china mobile IP carrying network, IP carrying network will finally become CMNET and IP specific carrying network. The CMNET carries traditional business of the Internet, and the IP specific carrying network carries soft switch,3G, BOSS, and so on.With the appearance of the business in soft switch,3G, GPRS and so on, the IP carrying network can not meet the need of the complex network, and it is very important to extend the IP carrying network. This paper is focus on the planning and implement of expansion of IP carrying network of Chongqing Mobile.This paper firstly describes the situation and question of the IP Specific carrying network and related nets, which includes IP carrying network, MDCN,2G Soft Switch, GPRS, Boss system and so on. The planning of network is made which is used to calculate the flow need of IP carrying network and related nets. What’s more, according to the flow requirement, the design of the extension of IP carrying network is made. The testing for the IP carrying network is done later which can not only approve the smooth of the link,but also demonstrate that the extend of IP carrying network which can provide a steady and efficient network transmission platform for kinds of application systems can meet the requirement well.
