The Fifth Generation (5G) cellular network requires new solutions to new network requirements, for example, support for high-speed mobility. This paper presents a handover decision solution for connected vehicles to 5G Ultra-Dense Networks (5G-UDN). Its main goal is to treat high vehicular mobility and provide performance gains in handover for vehicles, since the densification of the cellular network causes, despite the expected capacity gain, difficulties in the cells selection, a greater number of failed and unnecessary handovers (ping-pong effect), longer delays and energy consumption, and high packet losses. The solution is based on Virtual Cells (V-Cells). The selection of the best cells is made based on complex network metrics to compose a V-Cell, as well as other criteria such as signal strength, distance, and speed. The solution relies on the Software-Defined Network (SDN) controller which has centralized network information. Simulations were conducted in Network Simulator, ns-3. The results show that the solution is effective in the treatment of vehicle handover.

FiVH:超密集5G网络中联网车辆的V-Cell间切换决策解决方案

第五代(5G)蜂窝网络需要针对新网络要求的新解决方案,例如,对高速移动性的支持。本文提出了一种连接车辆到5G超密集网络(5G-UDN)的切换决策解决方案。它的主要目标是治疗车辆的高机动性,并为车辆的交接提供性能提升,因为尽管预期的容量增加,但蜂窝网络的致密化仍会导致小区选择困难,失败和不必要的交接数量增加(ping-乒乓效应),更长的延迟和能源消耗以及高丢包率。该解决方案基于虚拟单元(V-C​​ell)。基于构成V小区的复杂网络指标以及其他标准(例如信号强度,距离和速度)来选择最佳小区。该解决方案依赖于具有集中式网络信息的软件定义网络(SDN)控制器。模拟是在ns-3网络模拟器中进行的。结果表明该解决方案在车辆交接处理中是有效的。
