蘭州市核心網(wǎng)的建網(wǎng)方案

1、摘要在我國，目前已經(jīng)擁有了全球最大的移動通信網(wǎng)和最大的移動用戶數(shù)，移動用戶的數(shù)量已經(jīng)超過4億，而且這個(gè)數(shù)字還將快速增長?，F(xiàn)有的第二代移動通信系統(tǒng)無論是在頻譜資源，還是在所能提供的業(yè)務(wù)方面，都已經(jīng)不能滿足移動通信用戶的需求。本論文討論的WCDMA是一項(xiàng)全球應(yīng)用最廣、最成熟的3G技術(shù)，論文從WCDMA的應(yīng)用現(xiàn)狀出發(fā)，首先介紹了3G標(biāo)準(zhǔn)的提出及其商用情況，并簡要地闡述了研究WCDMA技術(shù)的意義。然后介紹了無線網(wǎng)絡(luò)系統(tǒng)，重點(diǎn)分析了無線網(wǎng)絡(luò)系統(tǒng)及

2、3G網(wǎng)絡(luò)的規(guī)劃與設(shè)計(jì)方法。接著重點(diǎn)分析了WCDMA網(wǎng)絡(luò)的規(guī)劃的流程和注意事項(xiàng)以及需要重點(diǎn)考慮的因素，并闡述了WCDMA核心網(wǎng)絡(luò)的規(guī)劃與設(shè)計(jì)方法。最后本文在對3G的市場需求進(jìn)行定性預(yù)測的基礎(chǔ)上，結(jié)合蘭州市的具體情況，分析了WCDMA網(wǎng)絡(luò)規(guī)劃時(shí)所需考慮的基本原則，提出在蘭州市構(gòu)建WCDMA核心網(wǎng)絡(luò)的預(yù)規(guī)劃方案。關(guān)鍵詞：關(guān)鍵詞：無線網(wǎng)絡(luò)，網(wǎng)絡(luò)規(guī)劃，容量規(guī)劃，核心網(wǎng)絡(luò)Ⅰ目錄1緒論.................................
