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是一項全球應用最廣、最成熟的3G技術，論文從WCDMA的應用現(xiàn)狀出發(fā)，首先介紹了3G標準的提出及其商用情況，并簡要地闡述了研究WCDMA技術的意義。然后介紹了無線網(wǎng)絡系統(tǒng)，重點分析了無線網(wǎng)絡系統(tǒng)及

2、3G網(wǎng)絡的規(guī)劃與設計方法。接著重點分析了WCDMA網(wǎng)絡的規(guī)劃的流程和注意事項以及需要重點考慮的因素，并闡述了WCDMA核心網(wǎng)絡的規(guī)劃與設計方法。最后本文在對3G的市場需求進行定性預測的基礎上，結合蘭州市的具體情況，分析了WCDMA網(wǎng)絡規(guī)劃時所需考慮的基本原則，提出在蘭州市構建WCDMA核心網(wǎng)絡的預規(guī)劃方案。關鍵詞：關鍵詞：無線網(wǎng)絡，網(wǎng)絡規(guī)劃，容量規(guī)劃，核心網(wǎng)絡Ⅰ目錄1緒論.................................
