Planning And Design Of 2G/3G Interoperability In Jinzhong Unicom

In the dual role of business requirements and technical advance,as a third generation mobile communication network technology, it has become a main development direction of evolution in major mobile operators. January 2009, the Ministry of Industry and Information Technology issued the WCDMA third generation mobile communication (3G) licenses to China Unicom.China Unicom began to launch WCDMA network construction and business development.In the early stage of WCDMA network planning and construction,we can not achieve the depth and breadth of network coverage,it is necessary to use the advantages of the existing 2G networks to make up for lack of early 3G network construction.Jinzhong Unicom planed and designed 2G/3G interoperability functions, and handled the relationship between network Phased implementation of the two networks coexist, complement each other. To improve the function of WCDMA network,we has played a pivotal role and to shorten the construction period, save investment cost, efficient use of existing resources to meet the market demand to play good results.With the constant development and construction of WCDMA network operators, WCDMA network will be gradually improved and 2G network will gradually replace. Accoring to the network conditions, we adjusted networks, played and performanced the real advantage of the WCDMA system. Subsequently, more and more ordinary people will use on the green, low-cost high-quality, content-rich third-generation mobile communications.
