Research On Optimization Of Urban Mobile TD-SCDMA Wireless Network

In recent years, with the large-scale construction and investment of TD-SCDMA(Time Division-Synchronous Code Division Multiple Access) network and the rapid development of mobile communication industry, the quality requirements of people’s mobile communication are increasing. The equality of network has become an important factor for the quality of mobile network, while the existing mobile communication system cannot meet the growing needs. Therefore, it has become the biggest problem to improve the performance of the network by optimization ways and avoid the resulting problems in the meantime.In this paper, we introduce the appearance of TD-SCDMA and briefly propose the si Gnificance of studying TD-SCDMA network. Taken Lanzhou city as an example, we investigate the current condition of city mobile communication technology, and analyze the key problems in city mobile network. Then we explain the process of the optimization work of TD-SCDMA and our initial preparation work, and analyze Lanzhou mobile network architecture, the feasibility of optimization objectives and evaluation of the network optimization. Finally, we use several optimization methods to optimize and analyse mobile network of Lanzhou.The results show that the specific program proposed in this paper for TD-SCDMA wireless network optimization can solve the problems about network coverage and service quality, and it is meaningful to further research on TD-SCDMA network.
