【摘要】：隨著移動(dòng)互聯(lián)網(wǎng)的快速發(fā)展，LTE（Long Term Evolution，3G系統(tǒng)的長期演進(jìn)技術(shù)）作為3GPP長期演進(jìn)技術(shù)目前已取得突破性進(jìn)展。TD-LTE網(wǎng)絡(luò)于2013年底正式商用，以其低時(shí)延、高速率的特性，將為國內(nèi)用戶提供高速、便捷的移動(dòng)數(shù)據(jù)網(wǎng)絡(luò)服務(wù)。TD-LTE網(wǎng)絡(luò)目前仍處于前期建設(shè)和優(yōu)化部署階段，根據(jù)其網(wǎng)絡(luò)特性和建設(shè)方式，如何做好網(wǎng)絡(luò)前期規(guī)劃、保證施工質(zhì)量、快速優(yōu)化網(wǎng)絡(luò)性能是建設(shè)精品TD-LTE網(wǎng)絡(luò)的關(guān)鍵。 本文描述了TD-LTE網(wǎng)絡(luò)的主要特征，包括物理層結(jié)構(gòu)、物理層過程等基礎(chǔ)知識(shí)，同時(shí)也詳細(xì)介紹TD-LTE的關(guān)鍵技術(shù)。本文在結(jié)合大學(xué)城的場景下，對(duì)大學(xué)城的TD-LTE網(wǎng)絡(luò)進(jìn)行規(guī)劃，并在此基礎(chǔ)上進(jìn)行網(wǎng)絡(luò)優(yōu)化。首先，，介紹了F頻段及D頻段網(wǎng)絡(luò)規(guī)劃原則，并在此原則之上確定了大學(xué)城的TD-LTE網(wǎng)絡(luò)規(guī)劃方案，利用仿真來完善方案，最終確定了工程施工方案。然后，利用規(guī)劃方案，對(duì)網(wǎng)絡(luò)進(jìn)行KPI指標(biāo)優(yōu)化，給出了優(yōu)化前后KPI指標(biāo)對(duì)比情況，并具體闡述了影響覆蓋、切換、重建及下載速率等常見問題及優(yōu)化方案，對(duì)實(shí)際網(wǎng)絡(luò)建設(shè)和優(yōu)化都具有較強(qiáng)的參考意義。
[Abstract]:With the rapid development of mobile Internet, LTEL long term Evolution (3G) as a long term evolution technology of 3GPP has made a breakthrough. TD-LTE network was officially commercially available at the end of 2013, with its characteristics of low delay and high speed. TD-LTE network will provide domestic users with high speed and convenient mobile data network service. TD-LTE network is still in the early stage of construction and optimization deployment. According to its network characteristics and construction mode, how to do a good job of network pre-planning to ensure construction quality, Fast optimization of network performance is the key to build TD-LTE network. This paper describes the main features of TD-LTE network, including the physical layer structure, physical layer process and other basic knowledge. At the same time, the key technologies of TD-LTE are also introduced in detail. In this paper, the TD-LTE network of the university town is planned and optimized based on the scenario of the university town. Firstly, the network planning principles of F band and D band are introduced, and the TD-LTE network planning scheme of university town is determined on the basis of this principle. The scheme is perfected by simulation, and the project construction scheme is finally determined. Then, using the planning scheme, the paper optimizes the KPI index of the network, gives the comparison of the KPI index before and after the optimization, and expounds the common problems and optimization scheme, such as influence coverage, handover, reconstruction and download rate, etc. It has a strong reference significance for the actual network construction and optimization.
