Critical Problem And Solution In Wireless Network Optimization

More and more attention has been paid to network service quality with the fast development of wireless network, continuous growth of wireless network scale and rapid increasing of mobile user. Network optimization is to improve quality and insure network resource to be used efficiently. The purpose of network optimization is to insure and improve network quality, to enhance enterprise competence and to improve customer satisfaction. Thus, the significance of network optimization is becoming more and more important.This paper briefly introduces GSM system architect and key technology and in detail illustrates and summarizes the main work principle of GSM network optimization of China Mobile Group Beijing Co., Ltd. The root cause of internal and external interference of GSM system and lack of Base Station coverage has been discussed deeply in this paper. Author puts forward solution and concrete step according to analysis.The category, root cause and solution of system external interference have been studied in this paper. Author makes deep theoretical study in shielding device of the cellular phone and provides whole solution. This paper introduces parameter optimization solution based on the user different feeling and scope to the interference in upper and down channel. The function and practice of Motorola real time interference search system has been introduced here. The problem that Base Station interference can not be searched by real time has been solved by this search system. By the use of this system, it is very helpful and important to find out, decrease and solve interference, to improve network quality and to bring positive economic and social benefit.Repeater working principle, main technical parameter and installing requirement have been studied here. Author introduces construction requirement, technical solution and main function of Repeater Monitoring Platform of China Mobile Group Beijing Co., Ltd. By implementing this system in whole network, China Mobile Group Beijing Co., Ltd can monitor the status and parameter of repeater run in network.
