| With the next generation network NGN core technology - Softswitch technology constantly improving, NGN in the network integration, business integration and rapid formation of the business advantages will gradually be reflected, in line with the trend of transformation of communication networks. 3G core network development direction is based on Softswitch technology bearing all-IP architecture, provide a tiered, open, reliable and scalable network system good.China Mobile has a complete and mature GSM network. How to maintain the existing business users and the smooth evolution of network security and stability operations on the basis of gradual introduction of Softswitch technology, the network's smooth transition, China Mobile is facing enormous challenges. The introduction of soft-switched networks will be a complex process, especially in the soft-switch technology is not mature and also the lack of GSM mobile Internet load in the mature large-scale application, select Softswitch deployment strategy and implementation steps are crucial.The Henan Mobile Communication core exchange network in 2007 to achieve the expansion of existing core network and the new exchange-aggregation and the use of all soft-exchange framework. The whole construction will be completed in early 2008, will achieve the existing GSM network and 3 G core network run in parallel, 3G initially established the basic framework for the core network.This paper around the Sanmenxia in Henan Mobile and mobile Softswitch, the introduction of the planning, construction, a study in the mobile Softswitch technology in-depth understanding on the basis of a detailed study of the Sanmenxia in Henan Mobile and mobile Softswitch deployment of the programme feasibility studies, traffic signaling and organizations , IP bearer network construction and network configuration data, and other aspects of the design and planning, proposed for the existing networks evolution of the core network solutions. |
