This article mainly research change power control parameter to voice dropout rate influence In the GSM System under different scene.Along with our country national economy enhancement , people's expense consciousness also has the earth-shaking change, the user is moving higher and higher the request of the network performance, because of moreover between the different network operator's competition, therefore the people take the network quality more and more quality, The network maintenance's key point pure maintenance of equipment shifts to network optimization that is the top level, if the operator will be in an impregnable position in future development, Takes the bigger market space, the good communication engineering quality is one of successful key aspects. The telephone conversation is the main standard of the network quality, the voice dropout rate reduces means that the conversation promotion, Now as well as change improves the voice dropout rate reason's analysis from handover, the cover angle to discuss, the power control has not been taken to improves primary dropout factor in the GSM system, Opening the power control in the station in initial period, therefore research which is the parameter of control power and the localization algorithm parameter to reduce the dropout rate, the promotion network's retentivity has the noticeable significance in the communication quality under the different environment adjusts in GSM system.The power control is to changes MS or the BTS transmission power with the wireless control mode.
