發(fā)布時(shí)間：2019-05-27 17:01
【摘要】：在傳統(tǒng)網(wǎng)絡(luò)數(shù)據(jù)流量爆發(fā)性增長、頻譜效率已接近極限值的形式下,異構(gòu)組網(wǎng)是增加網(wǎng)絡(luò)容量、提高數(shù)據(jù)速率的有效方式。LTE-A系統(tǒng)中異構(gòu)組網(wǎng)引入低功率節(jié)點(diǎn),縮短了網(wǎng)絡(luò)與用戶間距離,提高了無線鏈路質(zhì)量和頻譜效率,逐漸成為LTE-A系統(tǒng)中的關(guān)鍵技術(shù)之一,但同時(shí)也帶來復(fù)雜的移動(dòng)性管理等問題。在深入分析3GPP E-UTRA協(xié)議規(guī)范的基礎(chǔ)上,首先建立了LTE-A MacroPico異構(gòu)網(wǎng)絡(luò)拓?fù)淠Ｐ?然后對Macro-to-Pico和Pico-to-Macro雙向切換概率進(jìn)行了分析和仿真。在此基礎(chǔ)上,給出了用戶及其相關(guān)網(wǎng)絡(luò)參數(shù)對于切換成功概率的影響分析。
[Abstract]:In the form of explosive growth of traditional network data traffic and spectral efficiency close to the limit value, heterogeneous networking is an effective way to increase network capacity and improve data rate. Low power nodes are introduced into heterogeneous networking in LTE-A system. It shortens the distance between the network and the user, improves the quality of the wireless link and the spectrum efficiency, and gradually becomes one of the key technologies in the LTE-A system, but at the same time, it also brings complex mobility management and other problems. Based on the deep analysis of 3GPP E-UTRA protocol specification, the topology model of LTE-A MacroPico heterogeneous network is established, and then the bidirectional switching probability of Macro-to-Pico and Pico-to-Macro is analyzed and simulated. On this basis, the influence of users and their related network parameters on the success probability of handover is analyzed.
