Optimization Of WCDMA Packet Domain In Henan Unicom

From three communication operators published in October2011operation data to see, the first three quarters of this year,3G users growth has picked up speed, has hit the100million mark, reaching19.6million. And China unicom WCDMA nets in October for the first time more than the new users move, the total scale to reach33million users. The popularity of intelligent terminal brings group domain of business growth.The paper first WCDMA grouping of the development of the technology domain is presented, and the henan unicom WCDMA network situation are illustrated. Then it introduces due to business users group domain increasing demand, and to increase the group allied group domain of assessment index, packet domain special optimization arises at the historic moment. Then, the author will henan unicom WCDMA packet domain wireless side of the optimization tactics such as power resource allocation strategies, code resources allocation strategies, packet domain switching strategy made necessary is introduced.The author in the fourth chapter group domain for wireless side KPI highlighted in village system switch between the success rate of the poor do detail. From the definition, switching index analysis methods of process is introduced, the common in the neighbourhood, fast fading problems with leakage, YongHuKa reason, interference problems, parameter setting, etc gives the theoretical analysis and effective solutions. Chapter5the author mainly for DT/CQT test HSDPA, HSUPA rate of the poor do detail. From the user’s process of work, and find out the influence rate the question primary cause. In the HSDPA wireless environment of optimization, resources, adjust and optimize, parameter optimization is analyzed three ideas and solutions. In HSUPA aspects of the biggest impact in the net now RTWP made a detailed analysis of the problem.
