Cdma Mobile Communication Network Optimization

Nowadays, mobile communication is developing very well, and the number of subscribers is increasing dramatically.With the increasing of number of subscribers, the competitions between Network Service Providers are getting drastically, and users require higher quality of the communication systems at the same time. Due to lacking of experience and high speed development requirement during the early stages of cell communication networks, the real meaning of the networks are depending on the improving of the service level and profits of networks. Therefore, we should take actions on optimization for the networks.In this dissertation,we investigated on the states, development and trends of CDMA(Code-Division Multiple Address) wireless network optimization, the failure analysis and approaches of optimization,and also,we provide some advice of the optimization adjustment and parameter configuration. At the end of this work, we presented a CDMA networks optimization project in Chengdu, which includes the networks tests, data sampling, quality and capability analysis, and the adjustment scheme.The main contents consist of following several aspects:1. On the basis of the documents, the network optimization work flow and method are described. The network optimization is a long-term engineering across the total process of network development. Simultaneously it is a systematic engineering, concluding a series of optimization methods, such as handover optimization, traffic optimization, devices optimization, interference signal analysis, and the optimization utilization of funds. The environment of software and hardware is improved in the network optimization. The key works of optimization includes that investigation of current network, collection of data, drafting optimization scheme, implement and detection the optimization scheme. All the courses are continuous and cyclical to insure promoting the network quality and network running keep in the best status.2. The technologies of data collection of CDMA wireless network optimization are studied, concluding the contents, instruments and methods of the data collection. 3. The methods of failure analysis of CDMA wireless network are studied. Several typical kinds of network failure are analyzed, such as dropped call, failure of access, failure of soft-shifting and high FER (Frame Error Rate) etc.4. The experiences of CDMA wireless network optimization are summarized, concluding the measure of handover optimization, capacitances optimization, interference optimization and shifting performance.5. Combining with my career experience, the detection of CDMA wireless network and the collection of relative data in the district of Chengdu are implemented, the quality and performance of the network are analyzed, the adjustment scheme is drafted, and the optimization report is proposed.In a nut shell, all the related theories, methods and implements proposed in the research into CDMA wireless network optimization will be meaningful for the optimization of network resource configuration, improving environment of network, and promotion quality of network to keep it in the best status.
