摘 要

 隨著我國人民經濟生活水平的不斷提高，移動電話超常發展。這也使得移動網絡忙于建設期，從而移動網存在大量的規劃管理與優化需求。移動電話數量的飛速發展，尤其是近幾年農村中移動用戶的增長，使得原有初期建設的網絡面臨了一定的難題。目前在很多農村地區，網絡的問題困擾越來越明顯。這既影響了工作辦事效率也影響了移動電話在農村市場的發展。種種問題的發生，加上用戶對網絡質量需求的不斷增加，網絡優化顯得尤其重要。
 網絡優化工作是指“對正式投入運行的網絡進行參數采集、數據分析，找出影響網絡質量的原因并通過參數調整和其他技術手段，使網絡達到最佳運行狀態，使現有網絡資源獲得最佳效益，同時對網絡今后的維護及規劃建設提出合理建議” 的過程，它貫穿于網絡的整個生命期。
 本論文分析了邵陽地區GSM無線移動通信網絡發展現狀，通過對網絡監測，收集系統運營過程中各種動態的參數和統計數據，對網絡進行評估，從而修改和調整網絡的配置及參數，旨在提高網絡運行質量，保證運營部門能以經濟的投入獲得較高的收益。

The Optimization Of Countryside Wireless Communication Network
ABSTRACT
 As the developing of our country people's economic lives, mobile phone develop superiorly. This also causes the mobile network to be busy with construction period, thus the mobile network need massive programs manage and the demand of optimization. The quantity of mobile phone develop swiftly, particularly the last few years, the countryside mobile users's growth, make the original period construction of the network faced a certain hard. At present in many countryside areas, the problem harassment of network is getting more and more obvious. This since affected the work efficiency also affected the development of mobile phone in the rural market. The occurrence of various problems, and the users increase to the demand of network quality continuously, the optimization network appears especially important.
 The network optimization work refers to the process of carrying on parameter gathering, the data analysis in the network which formally throws in movement, find out the reason which influence network's quality and through the parameter adjustment and other technique means, make enables the network to achieve the best running status, make the existing network resource to obtain the best benefit, In the meantime we have to give the reasonable suggestion about the future network supporting and reasonable plans , it pierce through a period with the whole life of the network.
 In this thesis, the existing state of ShaoYang GSM digital mobile communication network is to be analyzed. The system is to be eva luated by monitoring the network and collecting all kinds of the dynamic parameters and statistic data of the operating system. And then, the configuration and parameters of network are modified and adjusted. The purpose is to increase the network quality and ensure that the business department obtains more gains by less spending.

Keywords: GSM mobile communication, Optimization network, Network overlay.
