摘要
隨著我國GSM數(shù)字移動通信事業(yè)的蓬勃發(fā)展，移動用戶對網(wǎng)絡(luò)質(zhì)量的要求越來越高，移動運營商也開始越來越重視移動網(wǎng)絡(luò)的質(zhì)量，因為移動運營商的核心競爭力就在于移動網(wǎng)絡(luò)質(zhì)量的好壞。網(wǎng)絡(luò)優(yōu)化是提高移動網(wǎng)絡(luò)質(zhì)量的最直接和最有效的方法，而其中對無線網(wǎng)絡(luò)的優(yōu)化又是網(wǎng)絡(luò)優(yōu)化中最重要、最復(fù)雜的一項內(nèi)容。論文對GSM網(wǎng)絡(luò)無線部分設(shè)計與優(yōu)化進行了深入研究。簡要介紹了GSM數(shù)字移動通信系統(tǒng)的發(fā)展現(xiàn)狀、系統(tǒng)基本構(gòu)成、各個子系統(tǒng)的結(jié)構(gòu)組成和各組成實體的各自作用、接口，并對無線部分的接口作了較為詳細(xì)的介紹。然后闡述了網(wǎng)絡(luò)優(yōu)化的重要意義，網(wǎng)絡(luò)優(yōu)化的基本概念、優(yōu)化目標(biāo)、網(wǎng)絡(luò)優(yōu)化的工作流程以及在無線網(wǎng)絡(luò)優(yōu)化中經(jīng)常使用的幾種方法。重點介紹了影響GSM網(wǎng)絡(luò)運行的主要技術(shù)指標(biāo)：掉話率、阻塞率、切換成功率、RACH接入有效性、分配失敗率的分析和優(yōu)化，提出了相應(yīng)改善指標(biāo)的解決辦法。再聯(lián)系現(xiàn)網(wǎng)實際情況，對日益復(fù)雜的無線環(huán)境進行了分析，對網(wǎng)絡(luò)中可能存在的干擾種類和原因，以及如何排除干擾的措施。并對影響GSM網(wǎng)絡(luò)覆蓋的重要因素，實施了切合工程實際的無線網(wǎng)絡(luò)優(yōu)化方案,大幅度提升網(wǎng)絡(luò)質(zhì)量,并以此為基礎(chǔ)進一步研究了用戶話務(wù)行為,用戶增長趨勢,對工程建設(shè)和網(wǎng)絡(luò)擴容提出了建議,完成了網(wǎng)絡(luò)規(guī)劃設(shè)計的初步方案。最后通過對無線優(yōu)化室內(nèi)覆蓋中一些實際案例的分析，理論與實際相結(jié)合，將網(wǎng)絡(luò)優(yōu)化的一些方法在實際工作中進行了驗證，，希望能對今后的優(yōu)化工作有所幫助，取得更好的效果。

Abstract
With China's GSM digital mobile communications business of booming development, mobile users for network quality request more and more high, mobile operators also begin to pay more and more attention to the quality of the mobile network, because mobile operators core competitiveness lies in mobile network quality. Network optimization is to improve the quality of the mobile network the most direct and effective method for the wireless network, and the optimization of the most important and network optimization, the most complex a content. Papers on GSM network wireless part design and optimization were studied. Briefly introduced the GSM digital mobile communication system's development present situation, the basic structure, system composition and structure of each subsystem each composition entity respective functions, interface, and the interface for wireless part are introduced in detail. And then expounds the important significance of network optimization, the basic concept of network optimization, optimizing targets, network optimization work process and in the wireless network optimization of several methods of frequently used. Mainly introduces the GSM network operation affect main technical indices: recent success rate, switching optimization.some, RACH access effectiveness, distribution, and the analysis and the optimization of failure, and puts forward corresponding solutions to improve indexes. Contact again real situation of net now increasingly complex and wireless environment of network was analyzed, and the possible presence of interference types and reasons, and how to remove interference measures. And the affecting the GSM network coverage of important factors, implement the wireless network with the practical engineering, greatly enhance network optimization scheme based on the quality, and studied the user traffic behavior, the user growth trend of engineering construction and network, the proposed expansion, completing the network planning and design of the preliminary scheme. Finally based on optimal indoor coverage of wireless some actual case analysis, combining theory with practice, some methods of network optimization in the practical work, and verifies the hope of future help optimize work, and get better results.

Keywords：GSM mobile communication network optimization
