发布时间：2019-05-27 17:01
【摘要】：在传统网络数据流量爆发性增长、频谱效率已接近极限值的形式下,异构组网是增加网络容量、提高数据速率的有效方式。LTE-A系统中异构组网引入低功率节点,缩短了网络与用户间距离,提高了无线链路质量和频谱效率,逐渐成为LTE-A系统中的关键技术之一,但同时也带来复杂的移动性管理等问题。在深入分析3GPP E-UTRA协议规范的基础上,首先建立了LTE-A MacroPico异构网络拓扑模型,然后对Macro-to-Pico和Pico-to-Macro双向切换概率进行了分析和仿真。在此基础上,给出了用户及其相关网络参数对于切换成功概率的影响分析。
[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.
