无人机基站的组切换
Group Handover for Drone Base Stations
摘要：
诸如物联网（IoT）和机器类型通信（MTC）之类的新技术的广泛使用迫使连接到移动网络的用户设备（UE）和MTC设备的数量增加。固有地，随着基站（BS）的覆盖区域内的UE的数量激增，服务质量（QoS）趋于下降。无人机安装的BS（UxNB）的使用是UE密集分布的地方（诸如体育场）的解决方案。UxNB作为一种有前途的技术出现，由于其快速部署，可用于未来的容量注入目的。然而，这种新兴技术引入了新的安全问题。相互认证、在地面BS和UxNB之间创建通信信道以及快速切换操作可能在使用UxNB进行容量注入时引起安全性问题。该新协议还建议执行从地面到UxNB的UE切换作为一个组。据作者所知，根据LTE和5G标准，BS之间没有认证解决方案。所提出的方案提供了用于由地面BS认证UxNB的解决方案。另外，在所提出的方法中不需要切换中的每个UE的证书共享阶段。没有证书共享步骤通过减少BS之间的通信数量来节省资源。此外，在所提出的组切换方法中，许多UE切换操作在简洁的时间内完成。
英文摘要：
The widespread use of new technologies such as the Internet of things (IoT) and machine type communication(MTC) forces an increase on the number of user equipments(UEs) and MTC devices that are connecting to mobile networks. Inherently, as the number of UEs inside a base station's (BS) coverage area surges, the quality of service (QoS) tends to decline. The use of drone-mounted BS (UxNB) is a solution in places where UEs are densely populated, such as stadiums. UxNB emerges as a promising technology that can be used for capacity injection purposes in the future due to its fast deployment. However, this emerging technology introduces a new security issue. Mutual authentication, creating a communication channel between terrestrial BS and UxNB, and fast handover operations may cause security issues in the use of UxNB for capacity injection. This new protocol also suggests performing UE handover from terrestrial to UxNB as a group. To the best of the authors' knowledge, there is no authentication solution between BSs according to LTE and 5G standards. The proposed scheme provides a solution for the authentication of UxNB by the terrestrial BS. Additionally, a credential sharing phase for each UE in handover is not required in the proposed method. The absence of a credential sharing step saves resources by reducing the number of communications between BSs. Moreover, many UE handover operations are completed in concise time within the proposed group handover method.
