Research On The Key Technology Of TD - SCDMA Network Optimization To Improve Download Rate

The main characteristics of the third generation mobile communication system is that the packet switching mode can provide wider bandwidth and faster speed,so as to guarantee the bandwidth for different business a higher rate. In three mainstream standards, although in terms of TDD spectrum utilization and the asymmetric, TD-SCDMA has a certain advantage, but single carrier peak load rate is congenitally deficient, which affects the user’s perception directly. On the other hand, beginning in 2012, TD network traffic increased significantly, the congestion, and network utilization is low, has not been effective utilization of resources, the shunt of G network data service is limited. Thus, improvement the the download rate of the TD network is an effective way to enhance user perception and TD network utilization.This paper by studying the double frequency optimization technology and the network parameter optimization technology, by implementing reasonable technical scheme improve the download speed of the network, this paper sums up the main of lanzhou in td-scdma network optimization problem and the solution. Double frequency optimization technology is through the network based information and network operation data, the analysis of the problems existing in the evaluation of the original network frequency planning, form the frequency planning scheme and optimizing after implementation of frequency planning schemes to network performance, improve the spectrum utilization, reduce the interference. Network optimization technology in wireless network structure, resources, key parameters and the depth of the RF optimization from four aspects, the deep reason analysis lanzhou ATU testing, the implementation of targeted optimization network download speed is implemented after ascension.Wireless network optimization is a very complicated work, which runs through the whole process of network construction. As a supplement to the TD-LTE network, TD-SCDMA network will play an important role in the future. It is a long time to improve data service download rate. This paper puts forward the optimization method and process of TD-SCDMA download rate, effectively improve the user’s perception and network utilization, and has certain guiding significance to the optimization of TD-SCDMA network in the future.
