Research On The Link Strategy Of Unicom U900 Network

WCDMA is the core technology of the third generation mobile communication technology of China Unicom.With the China Unicom 3G overall business continued growth spurt,the original UMTS2100 network mode has been unable to meet the remote rural and backward mountainous areas lack wide coverage for the depth of coverage is serious insufficient network weak coverage problem.These problems have gradually become the bottleneck restricting the development of China Unicom 3G users,U900 is also known as UMTS900,the world has nearly a hundred countries using U900 band as the WCDMA mode of networking.China Unicom Qinhuangdao branch as the province’s first introduced U900 multi standard equipment of different manufacturers synchronization network area,facing the U/G network construction,FDR(2+4)and a number of network construction situation of engineering construction,but also result in some regional network structure complexity continues to increase,the actual network a series of problems such as the replacement of old and new equipment.The significance of this study is to gradually solve the U900 network optimization analysis and a series of practical problems in the work,to ensure that the more remote areas of China Unicom 3G users can always carry in the most high-quality mobile network,UMTS900 network to enjoy high quality experience.Firstly we expound the causes and characteristics of network structure of U900 network construction,and analyze the advantages and disadvantages of the existing network and related key technologies,and then from the most common mode of universal equipment G/U system on U900 and G900 interoperability principle,and finally concludes Qinhuangdao branch for all kinds of Unicom U900 network scenarios bearing analysis of the strategy set,and through a large number of hand front road test analysis and parameter adjustment of background data summary,put forward a set of feasible strategies combined with the theory of U900 bearer services.According to China Unicom Qinhuangdao branch U900 network carrying strategy analysis,starting from the practice angle,in view of the complex pattern of thecoexistence of multiple network Unicom,put forward some practical ideas for network parameter programming based on U900 network,we hope to be able to China Unicom now fire construction and optimization of the U900 network such as tea help.
