论文摘要
网络切片已在5G/6G网络中引入，以应对提供具有不同要求的新服务的挑战。在5G和6G无线网络切片的设计中使用了SDN和NFV技术，以及对这些技术的控制的集中化，诸如资源日历之类的新服务也可以在无线网络中使用。在带宽日历中，具有低潜伏期灵敏度和大音量的流量转移到了以后的时间段，以便可以提供具有高潜伏期灵敏度的应用程序。我们讨论了如何在C-RAN体系结构中日历无线电资源，这也利用网络切片。这称为切片感知的无线电资源日历。该问题的模型是作为ILP问题开发的，并提出了两种启发式算法，以解决由于最佳解决方案的复杂性而解决的。观察结果表明，当租户之间共享资源时，接受的请求数量增加。
Network slicing has been introduced in 5G/6G networks to address the challenge of providing new services with different and sometimes conflicting requirements. With SDN and NFV technologies being used in the design of 5G and 6G wireless network slicing, as well as the centralization of control over these technologies, new services such as resource calendaring can also be used in wireless networks. In bandwidth calendaring, traffic with a low latency sensitivity and a high volume is shifted to later time slots so that applications with a high latency sensitivity can be served instead. We discuss how to calendar radio resources in the C-RAN architecture, which also makes use of network slicing. This is referred to as Slice-Aware Radio Resource Calendaring. A model of the problem is developed as an ILP problem and two heuristic algorithms are proposed for solving it due to complexity of optimal solution. Observations have shown that when resources are shared between tenants, the number of accepted requests increases.
