\r 1<\/strong>、產品簡介<\/span><\/strong><\/span> \r<\/p>\r

\r ES2410B 4G<\/span>（<\/span>LTE<\/span>）移動通信科研創新與實驗教學系統是在<\/span>TD-LTE<\/span>移動網絡如火如荼建設，大規模商用的背景下，武漢威士訊信息技術有限公司自主研發的新一代移動通信教學設備。該系統是在商用設備基礎上，經過專門改進，主要用于教師的科學研究和學生的創新實驗，其設計思路與實現方式均為國內首創，必將成為培養<\/span>4G<\/span>研發人才的新利器。<\/span><\/span> \r<\/p>\r

\r 2<\/strong>、產品背景<\/span><\/strong><\/span><\/strong><\/span> \r<\/p>\r

\r <\/span> \r<\/p>\r

\r 3G<\/span>移動通信的發展推動了移動數據業務和移動互聯網應用的發展，而移動數據與移動互聯網應用業務的發展又對移動帶寬性能提出了更高的要求，這直接驅動了以<\/span>LTE<\/span>（<\/span>Long Term Evolution<\/span>）為代表的第四代移動通信技術的發展。<\/span>LTE<\/span>是繼第三代移動通信之后國際上主流的新一代移動通信標準，面向未來的移動通信技術標準，是當前**先進的移動通信技術，集成了移動通信領域**的研究成果。<\/span>LTE<\/span>包括<\/span>FDD<\/span>和<\/span>TDD<\/span>兩種模式，其中的<\/span>TDD<\/span>（<\/span>Time Division Duplex<\/span>）模式即為<\/span>TD-LTE<\/span>，它是<\/span>TD-SCDMA<\/span>的后續演進技術與標準，屬于<\/span>TD-SCDMA<\/span>技術與標準的發展和未來演進的第二個階段，具有“<\/span>GAS <\/span>”優勢：“<\/span>G<\/span>”（<\/span>Global<\/span>，全球化），“<\/span>A<\/span>”（<\/span>Asymmetric<\/span>，非對稱）和“<\/span>S<\/span>”（<\/span>Synergetic<\/span>，共融性），更適合未來移動業務的應用。<\/span><\/span> \r<\/p>\r

\r LTE<\/span>采用正交頻分復用<\/span>(OFDM)<\/span>、多進多出天線<\/span>(MIMO)<\/span>等物理層關鍵技術以及通過網絡結構的調整獲得性能提升。<\/span>LTE-A<\/span>則引入載波聚合技術、增強型多天線技術、無線網絡編碼技術和無線網絡<\/span>MIMO<\/span>增強技術等，使性能指標獲得更大改善。<\/span>TD-LTE<\/span>網絡下行和上行峰值速度分別可達到<\/span>100Mbps<\/span>和<\/span>50Mbps<\/span>。<\/span><\/span> \r<\/p>\r

\r 無線行業組織4G Americas<\/span>發布報告稱，目前全球已有67<\/span>個**建成163<\/span>張商用LTE<\/span>網絡，全球124<\/span>個**或地區的415<\/span>家運行商投資LTE<\/span>，預計2013<\/span>年LTE<\/span>商用網絡總數將達256<\/span>個，多個預期中的LTE-Advanced<\/span>網絡（LTE-A<\/span>）也將推出。從2009<\/span>年5<\/span>月27<\/span>日瑞典啟動**個4G<\/span>試商用網絡至今，LTE<\/span>已逐漸走進我們的生活。<\/span> \r<\/p>\r

\r TD-LTE<\/span>作為TD-SCDMA<\/span>的后續演進標準已走出**，全球正式商用的TD-LTE<\/span>網絡已達14<\/span>個，市場初現規模。目前**正在北京、深圳、杭州等13<\/span>座城市進行TD-LTE<\/span>擴大規模試驗，計劃建設2<\/span>萬個TD-LTE<\/span>基站。在擴大規模試驗進行的同時，杭州、溫州、廣州、深圳及上海等城市已開始TD-LTE<\/span>試商用。在2013<\/span>年世界移動通信大會上**宣布，2013<\/span>年計劃在全國建立20<\/span>萬個基站、超過100<\/span>個城市布網，采購超過100<\/span>萬臺終端<\/span> \r<\/p>\r

\r 移動互聯網時代已經到來，3G<\/span>競爭更加激烈，智能手機加快普及，隨著產業和技術的成熟，TD-LTE<\/span>成為全球移動通信技術標準和市場發展主流的步伐正在加快。<\/span> \r<\/p>\r

\r <\/span> \r<\/p>\r

\r 3<\/strong>、系統組成<\/span><\/strong><\/span><\/strong><\/span> \r<\/p>\r

\r <\/span> \r<\/p>\r

\r 整個<\/span>TD-LTE<\/span>網絡包括三個組成部分：核心網（<\/span>EPC<\/span>）、接入網（<\/span>EUTRAN<\/span>）和終端（<\/span>UE<\/span>）。<\/span>EPC<\/span>即核心網部分，包括<\/span>MME(<\/span>移動性管理實體<\/span>)<\/span>、<\/span>S-GW(<\/span>服務網關<\/span>)<\/span>、<\/span>P-GW(<\/span>分組數據網網關<\/span>)<\/span>、<\/span>ESS(<\/span>歸屬用戶服務器<\/span>)<\/span>以及<\/span>PCRF<\/span>等功能實體。和<\/span>UMTS<\/span>相比，<\/span>NodeB<\/span>和<\/span>RNC<\/span>融合為<\/span>eNodeB<\/span>。在接口上，<\/span>eNodeB<\/span>和<\/span>EPC<\/span>之間通過<\/span>S1<\/span>口連接，<\/span>eNodeB<\/span>之間通過<\/span>X2<\/span>口連接，<\/span>eNodeB<\/span>和<\/span>UE<\/span>之間通過<\/span>Uu<\/span>口連接。<\/span><\/span>\r<\/p>\r
