The Application Research Of CDMA Radio Network Optimizing Technology

CDMA is a kind of advanced mobile telecommunication technology, which fulfill great capacity and quality,synthetical operation,soft switch and international ramble. It possesses lots of merits such as repellence of interference and attenuation of multiple paths. The security is also great trait of CDMA. CDMA is the main operation that China Unicom extend . The progress of CDMA right result in the success of China Unicom, and the development of operation must depend on perfect network. Therefore, in the process of management, it is completely necessary to optimize CDMA wireless network constantly. On the one hand, the purpose of optimizing CDMA wireless network is to provide more consummate service, and on the other hand, it is to extend system capacity in order to take up more and more consumers.The purpose of this task is to investigate the best methods that can optimize CDMA wireless network by collecting data of network which is in operation and analyzing the data in order to find the cause which influences the quality of the network. The advantage of CDMA is application of power control and soft switch, so they are usually the emphases during base station optimizing. On the other hand, data optimizing is also important and difficult. Concretely, methods of optimizing are as following: 1,optimization of power parameters 2,optimization of connection 3,discovering the problem of arithmetic and software 4,optimization of load control 5,optimization of dataIn this task, several practical wireless network communities were chose in which various interrelated data and parameter were noted. These data and parameters were analyzed carefully and we framed schemes which optimized CDMA wireless network. We optimized wireless network of the communities based on the schemes. Eventually, we checked up the feasibility of this task by compared correlative data with before.Eventually, we discuss the resource sharing between 2G and 3G wireless network .As there are great differences between 2G and 3G,it is very important to frame a scientific strategy of 3G wireless network and arrange it reasonable. In this paper, we discuss the modes and methods of sharing the two technical wireless networks, which include strategies of outside base stations and construction of inside base stations.
