5G异构网络中软件定义网络启用认证切换机制的设计

发布时间：2024-05-31 03:08

　　自第一代推出无线移动通信以来,已经过去了几十年,特别是主要由语音系统组成。在最近的几年里,世界目睹了无线通信向后代发展的连续但稳定的发展。实现各种数字调制,有效的频率复用,基于分组的互联网的优势以及物理层技术的连续进步,例如,正交频分复用(OFDMA),Wideband Code Division Multiple Access(W-CDMA),多输入多输出(MIMO),混合式自动重送请求(HARQ)投资于技术发展的成功。虽然智能的普及正逐渐增长,但每个基于IP的4G网络设备都成为日常生活的一部分。因此,面向用户的复杂应用程序,如视频交流,在线游戏,医疗保健服务,提供了广泛的业务范围,以增加收入。事实上,没有人会对各种智能设备感到惊讶,例如智能茶壶。此外,人们发现这些工具非常方便和有用。然而,为了确保能够提供适当质量的技术实现,下一代无线通信需要提供显着高的速率(显然为Gbps),极低的延迟,基站(BS)容量的极大扩大。此外,5G将在比较现有4G网络的感知服务质量(QoS)方面进行相当大的改进。上面提到的智能设备的传播,以及各种多媒体应用的注入,以及无线数据(主要是多媒体)的几乎指数上...
