Design And Implementation Of WCDMA-Based Large Telephone Traffic Simulation System

Marching into the information society, people would not be able to adapt to fast tempo life and work without information transmission .In order to satisfy the people that they can communicate anytime anywhere as well as be sure that their communications can be carried on reliably,mobile technology's development needs to speed up .At present , the mobile technology is evolving to the third generation which takes providing the voice , the data and the multimedia service as one body ,it may provide the high speed data transmission, the internet for users visit, the mobile video service and the multimedia service ,at the same time , it supports roaming though the whole world . WCDMA is the representative of the third generation ,after has analyzed the WCDMA system's essential technology , the system structure as well as related specifications, this article puts forward the WCDMA system's specification model, and we also has studied WCDMA system's Uu with emphasis. We use software simulated UE equipment of WCDMA system and carried on the large telephone traffic test to the system equipment based on the full understanding of the system and specification , the 3G products development and arrangement Of Zte, ltd. and the software engineering module design and good transplantable request , so as to achieve the goal of 3G system equipment 's stability . Through the strict module debugging, the large telephone traffic simulating system passed the test with NodeB ,RNC, and met the anticipated design requirement ,this system can speed up research development of 3G project, and also have the a good promotion and impetus function to 3G equipment 's early commercial use . The practice indicated that the research achievement of the this article and in which the design ideas and realization method described is reasonable ,practical and feasible .Regarding the similar development ,it has the certain reference value .
