Research Of CDMA2000 Network Optimization

CDMA2000 wireless network, which fulfills great capacity, high quality, integrated services, soft handoff and international ramble, is a kind of advanced mobile telecommunication technology with advantages as good anti-interference and anti-multipath fading performance, and high security. Nowadays, with the increase of the users,the capacity and quality of the CDMA2000 network is being tested as the higher requirements of the users. As a result, CDMA2000 wireless network optimization is needed to work continuously during the network optimization and upgrade.The purpose of the network optimization is to improve its performance so as to provide consummate service for the consumers and to extend system capacity to accept more and more consumers in the future. In the process of continuous network optimization, we should sum up the experience at any time in order to get some advice. Thus, it is important to carry on the network optimization, there is a great value for network operation and maintenance, network programming, and engineering construction.The subject mainly researches on the common problem of CDMA wireless network during the operation, and the problems of call connection, dropped calls and soft handoff is analyzed and discussed. Then, the common solution is listed. At the last of the thesis, combined with the results of the actual drive test problems, adjustment programs are given to test again to verify the correctness of the program. Finally, the feasible design is given after the network construction done before to improve the coverage of CDMA2000 wireless network and optimization capacity on the basis of basic situation of the district, network coverage, quality, traffic analysis, and existing theory and technology. The aim such as network capacity, quality, cost-effective, competitiveness will achieve the desired target to meet the need of the customers.
